Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The CDN is an intelligent virtual network constructed on the basis of the existing network, and by means of edge servers deployed in various places and functional modules of load balancing, content distribution, scheduling and the like of a central platform, a user can obtain required content nearby, network congestion is reduced, and the access response speed and hit rate of the user are improved.
In recent years, with the rapid popularization of intelligent terminals, the mobile internet has become a main way for people to obtain information. More and more users search information through search engines, and the loading speed of the information is very important in user experience. As a mode, a content delivery network may be used to cache a resource in a CDN edge node accessed by a user network, and when a user needs to access the resource, the resource may be obtained from a nearby CDN edge node without obtaining from a server, which reduces the waiting time of the user, thereby accelerating the loading speed of information. However, the inventor finds that, for a resource accessed for the first time, a CDN edge node needs to perform a back-sourcing process, and in some weak network environments, the CDN edge node has problems of a long time (1-10 seconds), unreliable quality (back-sourcing process is prone to fail), and the like during back-sourcing process due to network reasons, which may cause the length of back-sourcing process to be long, thereby affecting the resource loading speed and reducing user experience.
In view of the above problems, the inventors have found through long-term research that a broadcast message sent by a service server can be received by a client, where the broadcast message is sent when the service server detects that a resource is uploaded for the first time, and the broadcast message carries an identifier of the resource, and then a resource preloading request carrying the identifier of the resource is sent to a corresponding content distribution node, so that the content distribution node preloads the resource to the local. Therefore, through the above manner, the resource preloading request carrying the resource identifier is sent to the corresponding content distribution node by the client side when the broadcast message sent by the service server when detecting that the resource is uploaded for the first time is received, so that the content distribution node can preload the resource to the local, thereby realizing the pre-heating loading of the content distribution node on the resource, and through the pre-heating loading, the time length of the content distribution node for requesting the resource from the source station to the source is reduced, the first-time loading speed of the resource is accelerated, and the user experience is improved, so that the resource loading method, the device, the electronic device and the storage medium provided by the embodiment of the application are provided.
For the convenience of describing the scheme of the present application in detail, an application environment in the embodiment of the present application is described below with reference to the accompanying drawings.
Referring to fig. 1, an application environment schematic diagram of a resource loading method according to an embodiment of the present application is shown in fig. 1, where the application environment can be understood as a network system 10 according to an embodiment of the present application, where the network system 10 includes: client 12, client 13, CDN origin server 14, and CDN cache server 15.
The CDN origin station server 14 and the CDN cache server 15 may be one server (network access server), a server cluster (cloud server) composed of a plurality of servers, or a cloud computing center (database server). The client 12 and the client 13 may be any devices with communication and storage functions, including but not limited to a PC (Personal Computer), a PDA (tablet Personal Computer), a smart television, a smart phone, a smart wearable device, or other smart communication devices with network connection functions.
Optionally, the client 12 and the client 13 may be clients of an instant messaging application, a social network application, or an internet access application, where the client may be an application client (such as a video playing application in a mobile phone APP), or may be a web page client (such as a browser, a live webcast platform, and the like), and is not limited herein.
Alternatively, the CDN origin server 14 may establish communication connections with the client 12 and the various clients 13 over a network, which may be a wireless network, as one approach.
In one embodiment, the user may upload the resource to the CDN origin server 14 through the client 12, and the CDN origin server 14 may send the resource to each CDN cache server 15 for caching, so that the client 13 may request the resource from the CDN cache server 15 directly. Optionally, if the resource is a resource uploaded for the first time, when the client 13 requests the resource from the CDN cache server 15, the CDN cache server 15 needs to request the CDN origin server 14 for a back source, and in this way, the client 12 and the client 13 may be the same client (i.e., in this way, the client 12 may be identical to the client 13).
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a flowchart of a resource loading method according to an embodiment of the present application is shown, where the embodiment provides a resource loading method applicable to an electronic device, and the method includes:
step S110: the client receives the broadcast message sent by the service server.
Optionally, the broadcast message in this embodiment is sent by the service server when detecting that there is a resource to be uploaded for the first time, where the broadcast message carries an identifier of the resource to be uploaded for the first time. The resource may be a picture, a file, a page, or the like, and the type and content form of the resource may not be limited in this embodiment. The identifier may be understood as a target resource locator (i.e., a CDN-URL, where the CDN is a CDN cache server corresponding to a client that uploads resources, optionally, the CDN cache server in this embodiment may be understood as a content delivery node, optionally, a CDN cache node closest to the client and/or having the best network condition may be determined according to an IP address of the client as a corresponding content delivery node), and the target resource locator may represent a storage path of resources associated with the client that is generated by the service server, where the storage paths of resources associated with different clients may be different.
As one way, the client may receive the broadcast message sent by the service server based on a long connection channel with the service server. For example, a TCP connection between the client and the service server may be pre-established, in which case the client may receive the broadcast message sent by the service server based on a TCP long connection channel with the service server. For the establishment principle and the establishment process of the TCP connection between the client and the service server, reference may be made to related technologies, which are not described herein again.
Step S120: and sending a resource preloading request carrying the identifier of the resource to a corresponding content distribution node so that the content distribution node can preload the resource to the local based on the identifier of the resource.
As a manner, after obtaining the identifier of the resource, the client may send a resource preloading request carrying the identifier to the corresponding content distribution node according to the identifier, so that the content distribution node may preload the resource to the local based on the identifier of the resource. The resource is a resource requested by the client for the first time, and the content distribution node can be prompted to load the resource in advance by sending the preloading request, so that the loading time in the resource loading process can be reduced, and the resource loading speed is increased.
After the client sends the resource preloading request carrying the identifier to the corresponding content distribution node, the client may instruct the corresponding content distribution node to send the resource preloading request to the source station server (which may be understood as the CDN source station server), so that the resource corresponding to the identifier of the resource returned by the source station server may be obtained, and thus the corresponding content distribution node may preload the resource locally, reduce resource acquisition or time consumption for waiting in a subsequent service request process, and further improve user experience.
Optionally, the location of the client may be changed, for example, the client may move from location a to location B, and if the distance between location a and location B is long, the content distribution node corresponding to the client may be changed, that is, the content distribution node corresponding to the client in different locations may be different. Optionally, the specific distance between the position a and the position B in this embodiment may not be limited.
Optionally, in the process of changing the location of the client, the network environment may also change, for example, if the location of the client moves from the ground to the underground, the network signal may weaken, and in this way, if the client sends a resource preloading request carrying the identifier of the resource to the corresponding content distribution node, the sending may fail. As a way to improve this problem, after receiving a broadcast message sent by a service server, a client may first detect whether a network environment of a location where the client is located meets a preset condition, optionally, if the network environment of the location where the client is located meets the preset condition, the client may continue to send a resource preloading request carrying an identifier of the resource to a corresponding content distribution node; optionally, if the network environment of the location does not meet the preset condition, the client may delay sending the resource preloading request carrying the identifier of the resource to the corresponding content distribution node, where a specific duration of the delay may be adjusted according to an actual network environment condition. Optionally, the preset condition may be that the network signal of the network environment is greater than a specified threshold, and a specific value of the specified threshold may not be limited.
Optionally, after sending the resource preloading request carrying the identifier of the resource to the corresponding content distribution node, the client may detect whether a preloading request reception success signal returned by the service server is received, and optionally, if it is detected that the preloading request reception success signal returned by the service server is not received, the client may send the resource preloading request carrying the identifier of the resource to the corresponding content distribution node again, or continuously send the resource preloading request carrying the identifier of the resource to the corresponding content distribution node within a period of time, so as to ensure that the preloading request can be successfully sent.
In the resource loading method provided by this embodiment, a broadcast message sent by a service server is received by a client, where the broadcast message is sent when the service server detects that a resource is uploaded for the first time, and the broadcast message carries an identifier of the resource, and then a resource preloading request carrying the identifier of the resource is sent to a corresponding content distribution node, so that the content distribution node preloads the resource to the local. Therefore, through the above mode, the client side sends the resource preloading request carrying the resource identifier to the corresponding content distribution node under the condition that the client side receives the broadcast message sent by the service server when detecting that the resource is uploaded for the first time, so that the content distribution node can preload the resource to the local, the content distribution node can preheat and load the resource, the time length of the content distribution node for requesting the resource from the source station is reduced through preheating and loading, the first-time resource loading speed is accelerated, and the user experience is improved.
Referring to fig. 3, a flowchart of a resource loading method according to another embodiment of the present application is shown, where the embodiment provides a resource loading method applicable to an electronic device, and the method includes:
step S210: the client receives the broadcast message sent by the service server.
Step S220: and receiving the position identification of the client sent by the service server.
It will be appreciated that as the location of the client moves, the content distribution node corresponding to the client may change, for example, the content delivery node corresponding to the client at the location a is "CDN-1", the corresponding content delivery node at the position B is "CDN-2", optionally, the content delivery node CDN-1 and the content delivery node CDN-2 are different content delivery nodes, in this way, if the client receives the broadcast message sent by the service server at location a, and its location is changed from location a to location B within a short time (for example, 5 minutes, and the specific time may not be limited), in this way, if the client still sends a resource preloading request to the content distribution node corresponding to location a, poor transmission or transmission failure may be caused by poor network signals. As a way to improve this problem, the client in this embodiment may receive the location identifier of the client sent by the service server, and optionally, the location identifier is an identifier corresponding to the current location of the client.
The client may receive location data, which is periodically read by the service server and is related to the client, and further obtain a current location identifier of the client from the location data.
Step S230: and taking the content distribution node corresponding to the position identification as the corresponding content distribution node.
As one mode, after the location identifier of the client is obtained, the content distribution node corresponding to the location identifier may be used as the content distribution node corresponding to the client. Optionally, different location identifiers may correspond to different content distribution nodes, so that the content distribution node corresponding to the client may be accurately obtained according to the obtained location identifier.
Step S240: and sending a resource preloading request carrying the identifier of the resource to a corresponding content distribution node so that the content distribution node can preload the resource to the local based on the identifier of the resource.
In the resource loading method provided by this embodiment, the client receives the broadcast message sent by the service server, then receives the location identifier of the client sent by the service server, then uses the content distribution node corresponding to the location identifier as the content distribution node corresponding to the client, and then sends the resource preloading request carrying the identifier of the resource to the corresponding content distribution node, so that the content distribution node preloads the resource locally. The accurate sending of the resource preloading request is realized, so that the accuracy and the reliability of the resource loading are improved. The resource is preheated and loaded by the content distribution node, so that the time for the content distribution node to request the resource from the source station is shortened, the first loading speed of the resource is accelerated, and the user experience is improved.
Referring to fig. 4, a flowchart of a resource loading method according to another embodiment of the present application is shown, where the embodiment provides a resource loading method applicable to an electronic device, and the method includes:
step S310: and the service server acquires the resource locator of the resource sent by the client.
In this embodiment, the service server may be understood as a server corresponding to a browser, and a user may access resources to the service server through a client.
The Resource Locator may be understood as a Uniform Resource Locator (URL). As a mode, after uploading a resource to a CDN origin server for the first time, a client may obtain a URL returned by the CDN origin server, and optionally, a service server may receive the URL uploaded by the client, so that when receiving an access request for the resource, the service server may return an identifier to which the access request points to the corresponding client.
Step S320: generating an identification corresponding to the resource based on the resource locator.
Optionally, after obtaining the resource locator of the resource, the service server may generate an identifier corresponding to the resource based on the resource locator, for example, the service server may replace a URL uploaded by the client with a CDN-URL, and optionally, the CDN may be understood as a CDN cache server corresponding to the client uploading the resource.
Step S330: and if the resource is detected to be uploaded for the first time, sending a broadcast message of the first uploading of the resource to a target client.
Optionally, after generating the identifier corresponding to the resource, the service server may store the resource and the identifier corresponding to the resource in a mapping relationship, and optionally, if it is detected that the identifier identical to the identifier exists in the storage process, the service server may directly store the resource and the identifier identical to the identifier correspondingly. If the identifier identical to the identifier is not detected to exist, the resource can be judged to be uploaded for the first time, in this way, the service server can store the resource and the identifier corresponding to the resource in a correlation manner, and simultaneously send a message for uploading the resource for the first time to the target client, so that the target client can send a resource preloading request carrying the identifier of the resource to the corresponding content distribution node based on the broadcast message, and further the content distribution node can preload the resource to the local based on the identifier of the resource.
Wherein, the broadcast message carries the identifier of the resource. It should be noted that the number of target clients may be multiple, and the specific number may not be limited. In some implementations, the target client and the client uploading the resource may be the same client. For example, if the target client and the client that uploads the resource are the same client, the client uploads the resource to the source station server without storing the resource locally, so that the resource can be requested to be acquired when the resource needs to be used, the memory required by the resource is reduced, and the operation efficiency of the device is improved. Optionally, in other embodiments, the target client and the client that uploads the resource may not be the same client, and in this manner, when it is detected that the resource is first uploaded, the service server may send a broadcast message that the resource is first uploaded to at least one other client.
Alternatively, the service server may determine the target client from the plurality of clients in various ways. For example, as one way, the service server may select an active client from a preset number of clients, and then take the active client as a target client. The specific value of the preset number may not be limited, and the active client may be understood as a client with a higher access frequency (for example, the access frequency is greater than 5 times/hour/day, and optionally, the specific value and format of the access frequency may be set according to actual conditions), or may be understood as a client whose online duration exceeds a preset duration within a period of time (for example, a client whose online duration exceeds 3 hours within a day).
Optionally, as another mode, the service server may obtain account levels of a preset number of clients, and rank the account levels of the clients, and in this mode, a client with a top rank may be selected as a target client. For example, it is assumed that, among 1000 clients, the corresponding client levels include level 1, level 2, level 3, level 4, level 5, and level 6, and it is assumed that level 1< level 2< level 3< level 4< level 5< level 6, where the number of clients corresponding to level 6 is 5, the number of clients corresponding to level 5 is 17, the number of clients corresponding to level 4 is 39, the number of clients corresponding to level 3 is 300, the number of clients corresponding to level 2 is 420, the number of clients corresponding to level 1 is 219, and if the clients corresponding to level 4, level 5, and level 6 are selected as target clients, the number of target clients is 61.
In the resource loading method provided by this embodiment, the service server obtains the resource locator of the resource sent by the client, then generates the identifier corresponding to the resource based on the resource locator, and then sends the broadcast message that the resource is uploaded for the first time to the target client if it is detected that the resource is uploaded for the first time, so that the target client can send the resource preloading request carrying the identifier of the resource to the corresponding content distribution node based on the broadcast message, and further the content distribution node can preload the resource to the local based on the identifier of the resource, thereby reducing the time for the content distribution node to request the resource from the source station, accelerating the speed of the first loading of the resource, and further improving the user experience.
Referring to fig. 5, a flowchart of a resource loading method according to still another embodiment of the present application is shown, where the embodiment provides a resource loading method applicable to an electronic device, and the method includes:
step S410: and the service server acquires the resource locator of the resource sent by the client.
Step S420: generating an identification corresponding to the resource based on the resource locator.
Step S430: and if the resource is detected to be uploaded for the first time, sending a broadcast message of the first uploading of the resource to a target client.
Wherein, the broadcast message carries the identifier of the resource. Optionally, when the service server sends the broadcast message of the first resource upload to the target client, the target client may be a client that uploads the resource to the source station server for the first time, or may be another client. Optionally, as shown in fig. 5, if the target client is a client that uploads resources to the source station server for the first time, the service server may send a broadcast message that the resources are uploaded for the first time to the client 12 (as shown by a dashed arrow in fig. 5).
Step S440: and the client receives the broadcast message sent by the service server.
Step S450: and sending a resource preloading request carrying the identifier of the resource to a corresponding content distribution node so that the content distribution node can preload the resource to the local based on the identifier of the resource.
Referring to fig. 6 and fig. 7, the following describes the present embodiment by way of a specific example:
in a specific application scenario, assuming that a resource is a picture, as shown in fig. 6, a flow chart of timing when a client requests to access the picture from a content distribution node in the prior art provided by the embodiment of the present application is shown. As shown in fig. 6, the client 12 may locally upload the picture to the CDN origin server 14, the CDN origin server 14 may return an origin URL to the client 12, the client 12 may send the origin URL to the service server 11, and optionally the service server 11 may replace the origin URL with a CDN-URL.
In an embodiment, the client 13 may initiate a service request to the service server 11, and the service server 11 may return service data of the CDN-URL with the picture to the client 13 in response to the service request, in which case the client 13 (optionally, the client 13 and the client 12 may be the same client, or may not be the same client) may request the picture from the content distribution node 15 according to the CDN-URL. Optionally, if the request is a first request, since the picture is stored in the CDN origin server 14 and the content delivery node 15 does not cache the picture, as a manner, the content delivery node 15 may send a picture back-to-source request to the CDN origin server 14, and further may receive the picture returned by the CDN origin server 14. Optionally, after receiving the picture returned by the CDN source station server 14, the content delivery node 15 may cache the picture and return the picture to the client 13. It is understood that, in the process from the time the client 13 initiates the picture request to the time the client receives the picture, since the content delivery node needs to request the picture back to the CDN origin server, it may take a lot of time due to poor network and other reasons, and further slow down the speed of loading the picture, which affects the user experience.
As a way to improve the above problem, as shown in fig. 7, a long connection channel between the client 13 and the service server 11 may be established in advance, and optionally, the long connection channel may be a TCP long connection channel. Optionally, through the long connection channel, after the service server 11 receives the source station URL sent by the client 12, when the source station URL is converted into a CDN-URL and stored, if it is found that the resource is first uploaded, the broadcast message that the resource is first uploaded to the target client (for example, the target client may be the client 13 shown in fig. 7) is quickly sent to the target client at the moment, and then a new picture needs to be preheated when unicasting to another target client (which may be understood as unidirectional broadcast here).
As a manner, after receiving the broadcast message sent by the service server 11, the client 13 may silently initiate a CDN-URL request to the content distribution node 15, so that the content distribution node 15 may send a request to return a picture corresponding to the CDN-URL to the CDN source station server 14 in advance, and in this manner, because the picture is preheated and loaded in advance, the content distribution node may quickly return the picture returned by the CDN source station server 14 to the client 13, and through preheating and loading the picture, the picture loading speed is increased, and user experience is improved.
It should be noted that, in this embodiment, only the resource is taken as an example for description, and optionally, if the resource is a file or a page of another type, the loading principle and the process of the resource are similar to the above-mentioned principle and process of loading the picture, and are not described herein again.
In the resource loading method provided by this embodiment, the service server obtains the resource locator of the resource sent by the client, then generates the identifier corresponding to the resource based on the resource locator, and then sends the broadcast message of the first upload of the resource to the target client if it is detected that the resource is the first upload, so that the client can send the resource preloading request carrying the identifier of the resource to the corresponding content distribution node after receiving the broadcast message, and thus the content distribution node can preload the resource locally, thereby reducing the time for the content distribution node to request the resource from the source station, accelerating the speed of the first load of the resource, and further improving the user experience.
