Taking CDN as an example, by setting up a CDN node throughout the network to form a layer of intelligent virtual network on the basis of the existing Internet, the CDN node receives the request from the user terminal, returns the source to the source station, and stores the data accessed by the user terminal. When other user terminals continue to access the data, the CDN node that has stored the data directly provides the service. However, many of the responses of the source station are redirected Uniform Resource Locators (URLs). After the CDN node stores the redirected URL, the user terminal needs to continue to access the data content according to the redirected URL. Some data may need to be more. The secondary redirecting jump causes the user terminal to take a long time to obtain the target data content. In the prior art, there is a problem that the user terminal obtains data less efficiently.

The implementation, functional features, and advantages of the present invention will be further described in conjunction with the embodiments.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present invention provides a data push method. Referring to FIG. 1, in a first embodiment of the data push method of the present invention, the data push method includes:

Step S10: Upon receiving the service request sent by the user terminal, the content distribution network CDN node determines whether the service data pointed by the service request is currently stored.

The data pushing method provided in this embodiment can be applied to the Internet access. For example, when the CDN node receives the webpage access request of the user terminal and does not currently store the webpage data pointed by the webpage access request, the webpage access is performed according to the webpage. Retrieving the webpage data pointed to by the webpage access request to the source station server, and acquiring the webpage data that does not carry the redirected URL based on the redirected URL when the webpage data that the source station server responds with the redirecting URL; The CDN node stores the webpage data that does not carry the redirected URL as the webpage data pointed to by the webpage access request, and sends the webpage data that does not carry the redirected URL to the user terminal, which is easy to understand. When the stored webpage data that does not carry the redirected URL is accessed again, the CDN node can provide the service by using the stored webpage data that does not carry the redirected URL, thereby reducing response time and improving user terminal acquiring data. s efficiency.

Optionally, the user terminal generates the corresponding URL when receiving the URL input by the user in the browser-based address bar, or the click operation triggered by the hyperlink address displayed by the browser, or the playback operation triggered by the streaming media player. The service request (or the IP address) is sent to the CDN node; when receiving the service request sent by the user terminal, the CDN node determines whether the service data pointed by the service request is currently stored, according to the judgment result. The corresponding operation is performed, for example, when the service data pointed by the service request is stored, the CDN node may directly send the service data pointed by the service request to the user terminal.

In other embodiments, before step S10, the method further includes:

The CDN routing device receives the original service request sent by the user terminal, where the original service request carries the original URL requested by the user terminal, and the domain name corresponding to the original URL is the original domain name requested by the user terminal; The routing device returns a redirect response message to the user terminal, where the domain name corresponding to the URL carried by the redirect response message includes an acceleration node selected by the CDN routing device for the user terminal (described in the first embodiment) An identifier of the CDN node for the user terminal to send a service request to the CDN node, and the CDN node provides an acceleration service.

For example, the URL carried in the service request sent by the user terminal to the CDN routing device is http://www.ZTE.com/news/a.html, wherein the content corresponding to www.ZTE.com is content provider (Content Provider) Provided by CP), and providing a content distribution acceleration service through the CDN, the CDN routing device selects an acceleration node for the user terminal according to a predetermined policy (the identifier of the acceleration node is corresponding to the identifier C1 of the CDN node in the first embodiment), Construct a new URL at http://C1.cdn.net/www.ZTE.com/news/a.html. The user terminal sends a service request to the new URL to obtain the number of pages of the corresponding page stored by the CDN node. according to.

In step S20, when the service data pointed by the service request is not currently stored, and the service data pointed to by the service request carries the redirected unified data locator URL, the CDN node acquires not carried based on the redirected URL. Redirect the business data of the URL;

In this embodiment, when the service data pointed by the service request is not currently stored, the CDN node forwards the service request to the source station server according to the URL (or IP address) carried by the service request, to receive the The service data that the source station server responds to; when receiving the service data that is sent by the source station server, the CDN node determines whether the service data that the source station server responds carries the redirect URL, which can be understood by those skilled in the art. When the service data that the source station server responds carries the redirect URL, if the CDN node directly returns the service data that the source station server responds to the user terminal, the user terminal will receive according to the The redirected URL carried in the service data is redirected and then accessed to obtain the target data, wherein the user terminal may even need to be redirected multiple times during the process of continuing to access. Obviously, this is contrary to the original intention of the CDN. Therefore, in the embodiment, when the service data pointed by the service request (that is, the service data that the source station server responds based on the service request) carries the redirect URL, And the CDN node continues to determine whether the service data that is responded to by the source station server corresponding to the redirect URL is carried according to the redirected URL redirection, when receiving the service data of the source station server corresponding to the redirect URL. If there is a redirect URL, if yes, continue the redirect, otherwise go to step S30.

Step S30, the CDN node stores the service data that does not carry the redirected URL as the service data pointed by the service request, and sends the service data that does not carry the redirected URL to the user terminal;

In this embodiment, when the CDN node obtains the service data that does not carry the redirected URL, the service data that does not carry the redirected URL is stored as the service data pointed to by the service request, for the CDN node. When the service request is received again, the service data providing service that does not carry the redirected URL is directly used; and when the service data that does not carry the redirected URL is stored, the CDN node also performs the Carry redirect URL The service data is sent to the user terminal as the service data pointed by the service request for presentation to the user. In other embodiments, the CDN node may further send the service data that does not carry the redirected URL to the user terminal before or after storing the service data that does not carry the redirected URL.

Step S40: When currently storing the service data pointed by the service request, the CDN node directly sends the service data pointed by the service request to the user terminal.

It is easy to understand that the CDN node stores the service data in order to receive the service request for the stored service data again, and directly provides the service with the stored service data to achieve the purpose of network acceleration. Therefore, in this embodiment, When the service data pointed by the service request is currently stored, the CDN node directly sends the service data pointed by the service request to the user terminal for presentation to the user.

In other embodiments, the CDN node may also delete the stored service data when the service request for the stored service data is not received within a preset time period.

The preset time period may be set according to actual needs. For example, the preset time period is preferably set to 24 hours in the embodiment, and those skilled in the art may understand that the user is not accessed by periodically deleting for a long time. The business data can improve the utilization of the storage space of the CDN node.

In the data push method of the embodiment, when the CDN node receives the service request of the user terminal, if the service data pointed by the service request is not currently stored, and the service data pointed by the service request carries the redirect URL, The redirecting URL obtains the service data that does not carry the redirected URL, and stores the service data that does not carry the redirected URL as the service data pointed to by the service request, and the service data that does not carry the redirected URL. The service data that is directed to the service request is sent to the user terminal, and when the service request is received again, the CDN node can provide the service by using the stored service data that does not carry the redirect URL, without the user terminal. Perform redirected jumps to improve the efficiency of user terminals to obtain data.

Optionally, based on the first embodiment, a second embodiment of the data pushing method of the present invention is proposed. In the embodiment, before the step S40, the method further includes:

When the service data pointed to by the service request does not carry a redirect URL, perform the above step S40;

The CDN node updates the service data pointed by the service request by using the service data that does not carry the redirected URL, and sends the service data that does not carry the redirected URL to the user terminal.

It should be noted that, in actual applications, the service data stored by the CDN node may be historically acquired based on the prior art, and may exist with a redirect URL. Therefore, in this embodiment, to ensure the CDN. The node can effectively provide an acceleration service. When the service data pointed by the service request is currently stored, the CDN node first determines whether the service data pointed by the service request carries a redirect URL; if the service request points When the service data does not carry the redirected URL, the CDN node directly sends the service data pointed by the service request to the user terminal, so that the user terminal presents the user data to the user; if the service data pointed by the service request carries When there is a redirect URL, the CDN node obtains the service data that does not carry the redirected URL based on the redirected URL, and the CDN node obtains the service data that does not carry the redirected URL based on the redirected URL. The first embodiment is not described here; when the service data that does not carry the redirected URL is obtained, the CDN node is not carried. URL oriented service data updating service data point to the service request, and service data carries no redirect URL is transmitted to the user terminal, for their presentation to a user.

Optionally, based on the second embodiment, a third embodiment of the data pushing method of the present invention is proposed. In this embodiment, the service data pointed by the service request carries an HTTP status code, and the CDN node determines the service. The steps of the service data pointed to by the request carrying the redirect URL include:

It should be noted that the HTTP Status Code is a 3-digit code used to indicate the HTTP response status of the server. It is defined by the RFC 2616 specification and obtained RFC2518, RFC 2817, RFC 2295, RFC 2774, and RFC 4918. Specification extension. Specifically, the HTTP status code includes a message class status code of 1 header, a success class status code of 2 headers, a redirect class status code of 3 headers, a request error class status code of 4 headers, and a server of 5 prefixes. Error class status code, for example, the common HTTP status code "404" indicates that the request failed, the requested resource was not found on the server, and "404" is widely used when the server does not want to reveal exactly why the request was rejected or no other suitable The response is available.

In this embodiment, the CDN node determines whether the service data pointed by the service request carries a redirect URL based on the redirect header status code of the 3-word header. Specifically, the CDN node preferably passes the HTTP status code “301”. Or "302" to determine, that is, the preset HTTP status code is set to "301" or "302" in this embodiment. Wherein, 301" indicates that the requested resource has been permanently moved to the new location, and the new permanent URL is returned in the Location field of the response; "302" indicates that the requested resource temporarily responds from a different URL, and the temporary URL is The response is returned in the Location field.

For example, when the HTTP status code carried by the service data pointed by the service request that is extracted by the CDN node is “301” or “302”, it is determined that the service data pointed by the service request carries a redirect URL; When the HTTP status code carried by the service data pointed by the service request extracted by the CDN node is not “301” and is not “302”, the service pointed to by the service request is determined. The transaction data does not carry a redirect URL.

Optionally, based on the first embodiment, a fourth embodiment of the data pushing method of the present invention is provided. In this embodiment, when the type of the service data pointed by the service request is webpage data, the CDN node sends the Before the step of describing the business data pointed to by the business request, the method further includes:

It should be noted that in the Internet, there are various types of data, such as web page data, audio data, and video data. The text, pictures and other information that we see on the monitor are not what we see in the computer. Even if you know that all the information is stored on the hard disk, you can't see anything inside, just some discs. Suppose, if you magnify the disc with a microscope, you will see that the surface of the disc is uneven, the raised area is magnetized, and the concave area is not magnetized; the raised area represents the number 1, and the concave part represents the number 0. The hard disk can only use 0 and 1 to represent all text, pictures and other information. So how is the letter "A" stored on the hard disk? It is possible that the small computer storage letter "A" is 1100001, and the Xiaowang computer storage letter "A" is 11000010, so that the two sides will misunderstand when exchanging information. For example, Xiao Zhang sent 1100001 to Xiao Wang. Xiao Wang does not think that 1100001 is the letter "A". It may be considered as the letter "X". That is to say, Xiao Zhang and Xiao Wang's computers use different encoding methods. It can be understood by those skilled in the art that when the type of the service data pointed to by the service request is webpage data, only when the coding mode adopted by the user terminal is the same as the coding mode used by the service data pointed by the service request, The user terminal can normally present the service data pointed by the service request to the user, and ensure that the displayed webpage does not appear garbled.

In this embodiment, the service request sent by the user terminal to the CDN node includes an encoding mode adopted by the user terminal, and the CDN node may be parsed by The "charset=xxx" field in the service data pointed to by the service request determines the coding mode used by the service data pointed by the service request, where the "xxx" part is the code used by the service data pointed by the service request. Commonly used codes include GB2312, GBK, UTF-8, ISO8859-1 and so on. After determining the coding mode adopted by the user terminal and determining the coding mode used by the service data pointed by the service request, the determination may be performed.

Optionally, after the step of determining, by the CDN node, that the coding mode used by the service data to be used by the service request is the same as the coding mode adopted by the user terminal, the CDN node further includes:

It is easy to understand that when the coding mode adopted by the user terminal is different from the coding mode used by the service data pointed by the service request, the CDN node uses the coding mode of the user terminal to request the service pointed by the service request. The data is re-encoded, and the re-encoded service data is available for the user terminal to be parsed normally, and the webpage content is presented to the user.

It can be understood by those skilled in the art that, in other embodiments, after the CDN node obtains the service data that does not carry the redirected URL from the source station server, the CDN node may separately use the multiple common coding modes to The service data carrying the redirected URL is re-encoded, and the re-encoded service data is separately stored to further improve the efficiency of the user terminal to obtain data.

Optionally, the present invention further provides a data pushing device. Referring to FIG. 2, in the first embodiment of the data pushing device of the present invention, the data pushing device includes:

The first determining module 10 is configured to determine, when the CDN node that the content distribution network is located, receives the service request sent by the user terminal, whether the CDN node currently stores the service data pointed by the service request;

The data pushing device provided in this embodiment can be applied to Internet access, for example, The data pushing device provided by the embodiment is built in the CDN node, and the CDN node receives the webpage access request of the user terminal, and does not currently store the webpage data pointed by the webpage access request, according to the webpage access request. The source station server returns the webpage data pointed to by the webpage access request, and obtains webpage data that does not carry the redirected URL based on the redirected URL when the webpage data that the source station server responds with the redirecting URL; The CDN node stores the webpage data that does not carry the redirected URL as the webpage data pointed to by the webpage access request, and sends the webpage data that does not carry the redirected URL to the user terminal, which is easy to understand When the stored webpage data that does not carry the redirected URL is accessed again, the CDN node can provide the service by using the stored webpage data that does not carry the redirected URL, thereby reducing the response time and improving the efficiency of the user terminal acquiring data. .

Optionally, the user terminal generates the corresponding URL when receiving the URL input by the user in the browser-based address bar, or the click operation triggered by the hyperlink address displayed by the browser, or the playback operation triggered by the streaming media player. The service request of the (or IP address) is sent to the CDN node where the first determining module 10 is located; the first determining module 10 determines the CDN when receiving the service request sent by the user terminal based on the CDN node. Whether the node currently stores the service data pointed by the service request, so as to perform a corresponding operation according to the determination result, for example, when the service data pointed by the service request is stored, the service data pointed by the service request may be directly sent. To the user terminal.

In other embodiments, before the first determining module 10 determines whether the CDN node currently stores the service data pointed by the service request, the first determining module 10 further includes:

For example, the URL carried in the service request sent by the user terminal to the CDN routing device is http://www.ZTE.com/news/a.html, wherein the content corresponding to www.ZTE.com is CP (Content Provider, content) The provider provides, and provides a content distribution acceleration service through the CDN, and the CDN routing device selects an acceleration node for the user terminal according to a predetermined policy (the identifier of the acceleration node is corresponding to the identifier C1 of the CDN node in the first embodiment), constructing a new The URL is http://C1.cdn.net/www.ZTE.com/news/a.html. The user terminal sends a service request to the new URL to obtain page data of a corresponding page stored by the CDN node.

The obtaining module 20 is configured to: when the CDN node does not currently store the service data pointed by the service request, and the service data pointed by the service request carries the redirected unified data locator URL, based on the redirect URL Obtaining business data that does not carry a redirect URL;

In this embodiment, when the CDN node does not currently store the service data pointed by the service request, the obtaining module 20 forwards the service request to the source station server according to the URL (or IP address) carried by the service request, Receiving the service data of the source station server response; when the CDN node receives the service data of the source station server response, the obtaining module 20 determines whether the service data that the source station server responds carries Oriented URL, as can be understood by those skilled in the art, when the service data that the source station server responds carries the redirected URL, if the service data responded to by the source station server is directly returned to the user terminal, The user terminal will re-access according to the redirected URL carried in the received service data, and then obtain the target data, wherein the user terminal may even need to be redirected multiple times during the process of continuing to access. Obviously, this is contrary to the original intention of the CDN. Therefore, in the embodiment, when the service data pointed by the service request (that is, the service data that the source station server responds based on the service request) carries the redirect URL, The obtaining module 20, based on the redirected URL redirection, continues to determine whether the service data responded by the source station server corresponding to the redirected URL is received when receiving the service data of the source station server corresponding to the redirected URL. If the redirected URL is carried, the redirect is continued. Otherwise, the obtained service data that does not carry the redirected URL is pushed to the sending module 30 for processing.

The sending module 30 is configured to store the service data that does not carry the redirect URL as the service data pointed by the service request, and send the service data that does not carry the redirect URL. Sent to the user terminal;

In this embodiment, when the service data that does not carry the redirected URL is obtained, the sending module 30 stores the service data that does not carry the redirected URL as the service data pointed to by the service request, to receive the service again. When the request is made, the service data providing service that does not carry the redirected URL is directly used; and when the service data that does not carry the redirected URL is stored, the sending module 30 further sends the redirected URL. The service data is sent to the user terminal as the service data pointed to by the service request for presentation to the user. In other embodiments, the sending module 30 may further send the service data that does not carry the redirected URL to the user terminal before or after storing the service data that does not carry the redirected URL.

The sending module 30 is further configured to directly send the service data pointed by the service request to the user terminal when the CDN node currently stores the service data pointed by the service request.

It is easy to understand that the CDN node stores the service data in order to receive the service request for the stored service data again, and directly provides the service with the stored service data to achieve the purpose of network acceleration. Therefore, in this embodiment, When the service data pointed by the service request is currently stored, the sending module 30 directly sends the service data pointed by the service request to the user terminal for presentation to the user.

In other embodiments, the data pushing apparatus further includes a deleting module, configured to delete the stored service data when the CDN node does not receive a service request for the stored service data within a preset time period.

The data pushing device provided in this embodiment is built in the CDN to receive the operation, and when the CDN node receives the service request of the user terminal, if the service request is not currently stored, The service data, and the service data that the service request is directed to carry the redirect URL, the service data that does not carry the redirect URL is obtained based on the redirected URL, and the service data that does not carry the redirect URL is stored as The service data pointed to by the service request, and the service data not carrying the redirect URL is sent to the user terminal as the service data pointed by the service request, and when the service request is received again, the CDN node is The stored service data that does not carry the redirected URL can be used to provide a service, and the user terminal does not need to perform a redirect jump, thereby improving the efficiency of the user terminal to obtain data.

Optionally, based on the first embodiment, a second embodiment of the data pushing device of the present invention is provided. In this embodiment, the data pushing device further includes a second determining module, configured to be currently stored in the CDN node. When the service data pointed to by the service request is determined, it is determined whether the service data pointed by the service request carries a redirect URL;

The sending module 30 is further configured to: when the service data pointed by the service request does not carry the redirecting URL, directly send the service data pointed by the service request to the user terminal;

The obtaining module 20 is further configured to: when the service data pointed to by the service request carries the redirecting URL, obtain the service data that does not carry the redirected URL based on the redirected URL;

The sending module 30 is further configured to update the service data pointed by the service request by using the service data that does not carry the redirect URL, and send the service data that does not carry the redirect URL to the user terminal.

It should be noted that, in actual applications, the service data stored by the CDN node may be historically acquired based on the prior art, and may exist with a redirect URL. Therefore, in this embodiment, to ensure the CDN. The node can effectively provide the acceleration service. When the service data pointed by the service request is currently stored, the second determining module first determines whether the service data pointed by the service request carries a redirect URL; if the service request points When the service data does not carry the redirected URL, the sending module 30 directly sends the service data pointed by the service request to the user terminal, so that the user terminal presents the user data to the user; The obtaining module 20 obtains the service data that does not carry the redirected URL based on the redirected URL, where the obtaining module 20 obtains the non-portable based on the redirected URL. For the service data of the redirected URL, reference may be made to the first embodiment, and details are not described herein. When the service data that does not carry the redirected URL is obtained, the sending module 30 updates the service data that does not carry the redirected URL. The service data pointed to by the service request, and the service data not carrying the redirect URL is sent to the user terminal for presentation to the user.

In addition, in this embodiment, the obtaining module 20 determines whether the service data that the source station server responds carries the redirect URL by calling the second determining module.

Optionally, based on the second embodiment, a third embodiment of the data pushing apparatus of the present invention is proposed. In this embodiment, the service data pointed by the service request carries an HTTP status code, and the second determining module further sets Determining whether the HTTP status code carried by the service data pointed by the service request is consistent with a preset HTTP status code, where the service status is directed to the service data when the HTTP status code is consistent with the preset HTTP status code. Carry a redirect URL.

In this embodiment, the second determining module determines, according to the redirecting class status code of the 3-word header, whether the service data pointed by the service request carries a redirecting URL. Specifically, the second determining module preferably passes the HTTP state. The code "301" or "302" is judged, that is, the preset HTTP status code is set to "301" or "302" in this embodiment. Where 301" indicates that the requested resource has been forever Moved to the new location for a long time, and the new permanent URL is returned in the Location field of the response; "302" indicates that the requested resource temporarily responds from a different URL, and the temporary URL is returned in the Location field of the response.

For example, when the HTTP status code carried by the service data pointed by the service request by the second determining module is “301” or “302”, it is determined that the service data pointed by the service request carries a redirect URL; The service data pointed to by the service request does not carry the redirected URL when the HTTP status code carried by the service data that is sent by the CDN node is not "301" and is not "302".

Optionally, based on the first embodiment, a fourth embodiment of the data pushing and loading device of the present invention is provided. In this embodiment, when the type of the service data pointed by the service request is webpage data, the data pushing device And a third determining module, configured to determine whether the encoding mode used by the service data pointed by the service request is the same as the encoding mode adopted by the user terminal;

It should be noted that in the Internet, there are various types of data, such as web page data, audio data, and video data. The text, pictures and other information that we see on the monitor are not what we see in the computer. Even if you know that all the information is stored on the hard disk, you can't see anything inside, just some discs. Suppose, if you magnify the disc with a microscope, you will see that the surface of the disc is uneven, the raised area is magnetized, and the concave area is not magnetized; the raised area represents the number 1, and the concave part represents the number 0. The hard disk can only use 0 and 1 to represent all text, pictures and other information. So how is the letter "A" stored on the hard disk? It is possible that the small computer storage letter "A" is 1100001, and the Xiaowang computer storage letter "A" is 11000010, so that the two sides will misunderstand when exchanging information. For example, Xiao Zhang sent 1100001 to Xiao Wang. Xiao Wang does not think that 1100001 is the letter "A". It may be considered as the letter "X". That is to say, Xiao Zhang and Xiao Wang's computers use different encoding methods. Those skilled in the art can understand that When the type of the service data pointed to by the service request is webpage data, the user terminal can normally perform the same manner only when the coding mode adopted by the user terminal is the same as the coding mode used by the service data pointed by the service request. The business data pointed to by the service request is presented to the user to ensure that the displayed webpage is not garbled.

In this embodiment, the service request sent by the user terminal to the CDN node includes an encoding mode adopted by the user terminal, and the third determining module may parse the service data pointed by the service request. The "charset=xxx" field determines the coding mode used by the service data pointed to by the service request, wherein the "xxx" part is the code used by the service data pointed by the service request, and the commonly used codes include GB2312, GBK. , UTF-8, ISO8859-1 and so on. After determining the coding mode adopted by the user terminal and determining the coding mode used by the service data pointed by the service request, the third determining module may perform the determination.

Optionally, in order to ensure that the webpage can be displayed normally, the sending module 30 is further configured to use the user terminal when the encoding mode used by the service data pointed by the service request is different from the encoding mode adopted by the user terminal. The encoding mode re-encodes the service data pointed by the service request, and sends the re-encoded service data to the user terminal.

It is easy to understand that when the coding mode adopted by the user terminal is different from the coding mode used by the service data pointed by the service request, the sending module 30 uses the coding mode of the user terminal to point to the service request. The service data is re-encoded, and the re-encoded service data is available for the user terminal to be parsed normally, and the webpage content is presented to the user.

It can be understood by those skilled in the art that, in other embodiments, after the obtaining module 20 obtains the service data that does not carry the redirected URL from the source station server, the sending module 30 may also adopt a plurality of commonly used ones. The encoding method re-encodes the service data that does not carry the redirected URL, and separately stores the re-encoded service data, so as to further improve the efficiency of the user terminal to obtain data.

Embodiments of the present invention also provide a storage medium. Optionally, in this embodiment, an execution instruction is stored in the storage medium, and the execution instruction is used to execute the foregoing method.

Optionally, in the embodiment, the foregoing storage medium may include, but is not limited to, a USB flash drive, a Read-Only Memory (ROM), and a Random Access Memory (RAM). A variety of media that can store program code, such as a hard disk, a disk, or an optical disk.

The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformations made by the description of the present invention and the drawings are directly or indirectly applied to other related technical fields. The same is included in the scope of patent protection of the present invention.
