Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application is described next in connection with fig. 1 and 2.
Specifically, fig. 1 is an optional system architecture for implementing access to public network resources under an IPTV private network according to an embodiment of the present application, where, as shown in fig. 1, the system architecture may include: a terminal 10, a proxy gateway 20, a service server 30. The terminal 10 is a terminal in an IPTV network, the proxy gateway 20 is a server capable of performing data interaction with the terminal 10 and the service server 30, and the service server is a server in the public internet.
The terminal 10 may be a set-top box, and is capable of supporting playing of public network playing resources returned by the proxy gateway. Further, through the terminal 10, the user can realize various operations such as watching video, listening to music, and surfing lessons at the TV end.
The proxy gateway 20 and the service server 30 may be composed of a plurality of servers, where the proxy gateway 20 may be a server provided by a target application manufacturer or a server provided by an IPTV private network manufacturer.
The proxy gateway 20 can receive the playing resource matched with the target service selected by the user and sent by the service server 30, and send the playing resource to the terminal 10, so that the terminal 10 plays the playing resource.
Based on this, the present application can help the terminal 10 under the IPTV private network play the purpose of the public network resources.
Based on the system architecture shown in fig. 1, fig. 2 shows an optional signaling flow of a method for accessing public network resources under an IPTV private network according to an embodiment of the present application.
Referring to fig. 2, the flow is specifically as follows:
step S110, the terminal 10 responds to the operation of selecting the target service under the target application on the terminal 10 by the user, and obtains the proxy gateway address and the URL address corresponding to the terminal service from the target application.
Specifically, the user may select the target service under the target application in various manners, for example, the user selects through infrared remote control, and the user may also select through a key on the terminal 10.
The target application is an application that needs to access a public network playing resource, and when the application app that needs to access the public network playing resource and is installed on the terminal 10 is manufactured, a manufacturer can write a proxy gateway address corresponding to the application app in a code of a product, and can write a URL address corresponding to a product service in a code corresponding to the service. When the installed application app updates the service, the corresponding URL address may be written in the updated service code at the same time.
Different applications in the same terminal 10 may correspond to different proxy gateway addresses, or may correspond to the same proxy gateway address, and the same application in the terminal 10 may correspond to only the same proxy gateway address.
The URL addresses corresponding to different services in the same application app can be different, and the domain names of the URL addresses in the same application app can be the same or different.
Based on the above, when the user selects the target service under the target application, the proxy gateway address and the URL address corresponding to the target service can be obtained.
In step S120, the terminal 10 performs a first conversion process on the URL address to obtain a processed character string.
Specifically, the present application may perform the first conversion process on the URL address in various manners, and may convert the URL address into binary or decimal.
After the first conversion process, the character string does not contain the domain name of the unprocessed URL address.
In step S130, the terminal 10 combines the proxy gateway address and the processed character string to serve as a service request address.
Specifically, the service request address points to a proxy gateway.
The processed character strings can be spliced at the tail end of the proxy gateway address for combination. After the merging is completed, only one domain name in the obtained service request address, namely the domain name with the proxy gateway exists.
Step S140, the terminal 10 invokes the player and sends the service request address.
Specifically, the player is an application in the terminal 10, and the terminal 10 sends the service request address to the proxy gateway 20 through its application, i.e., the player.
Wherein the service request address includes the proxy gateway address and the processed character string, and the processed character string can be obtained after the proxy gateway 20 receives the service request address.
Step S150, the proxy gateway 20 performs a second conversion process on the processed character string, and obtains the URL address after the second conversion process.
Specifically, the second conversion process is an inverse process of the first conversion process. Therefore, the proxy gateway 20 performs the second conversion processing on the processed character string, and then obtains the URL address.
Step S160, the proxy gateway 20 sends the URL address.
Specifically, the proxy gateway 20 sends the URL address to the service server 30, and the service server 30 corresponds to the target service.
Step S170, the service server 30 sends the public network playing resource corresponding to the URL address.
Specifically, after the service server 30 receives the URL address, it may search for the public network play resource corresponding to the URL address. After the service server 30 obtains the public network playing resource, the public network playing resource may be sent to the proxy gateway 20.
The public network playing resource corresponds to the URL address, and the URL address corresponds to the target service, so the target service corresponds to the public network playing resource.
Step S180, the proxy gateway 20 sends the public network playing resource.
Specifically, after receiving the public network play resource, the proxy gateway 20 may send the public network play resource to the terminal 10.
Step S190, the terminal 10 plays the public network playing resource.
Specifically, after receiving the public network playing resource, the player in the terminal 10 may play the public network playing resource.
As can be seen from the above technical solution, in the method for accessing public network resources under an IPTV private network provided by the embodiments of the present application, when a player in a terminal 10 has a requirement for playing public network playing resources, the public network playing resources corresponding to a target service may be obtained, and the public network playing resources sent by a proxy gateway 20 may be played. Therefore, the application can realize that public network playing resources are obtained and played by accessing the public Internet under the IPTV private network.
Furthermore, the proxy service address and the URL address can be obtained from the target application, the IPTV operator is not required to carry out routing configuration, DNS configuration or network transformation on the IPTV private network, the set top box is not required to carry out any configuration change and setting, and the like, so that the security risk of various configurations and unpredictable influence caused by improper operation are effectively reduced, the threshold of the application for accessing the IPTV private network is greatly reduced, and the realization cost is low. In addition, the method does not need additional operation or configuration by a user, is simple and easy to implement, and is convenient to popularize and implement.
Next, an embodiment of the present application will be further described with respect to the terminal 10, which is a method for accessing public network resources under an IPTV private network according to the present application.
The terminal 10 has been described above as being capable of performing a first conversion process on the URL address to obtain a processed character string. Further, the process of performing the first conversion processing on the URL address by the terminal 10 to obtain the processed character string will be described in detail below.
Specifically, in some embodiments of the present application, the terminal 10 may perform a first conversion process on the URL address as a whole, to obtain a processed character string.
Wherein the URL address is entirely the entire URL address, i.e., the terminal 10 converts the entire URL address into a character string.
Further, in some embodiments of the present application, the terminal 10 may perform a first conversion process on the domain name in the URL address to obtain a first string, and then splice a second string in the URL address except for the domain name at the end of the first string to obtain a processed string.
Specifically, the URL address may include a domain name and an access path, and the terminal 10 may perform a first conversion process on the domain name to obtain a first string corresponding to the domain name. And then, splicing the first character string and the access path to obtain the processed character string.
The above technical solution introduces two specific contents that can perform the first conversion process, for example, the first conversion process can be performed on the entire URL address, or the first conversion process can be performed only on the domain name of the URL address, so that the corresponding processing mode can be selected according to the length of the URL address. For example, when the length of the URL address exceeds a certain threshold, the first conversion process is performed only on the domain name, so as to reduce the time for performing the first conversion process on the URL address. Therefore, the time for accessing the public network resources under the IPTV private network can be reduced, and the public Internet can be better accessed to acquire the public network playing resources for playing.
Next, a processing mode of the first conversion processing will be described in detail.
In some embodiments of the present application, the first conversion process may be an encryption process.
Specifically, the encryption processing manner may include any one of the following: MD5 encryption algorithm, triple DES encryption algorithm, IDEA encryption algorithm, skip encryption algorithm, RC4 encryption algorithm, RC5 encryption algorithm. For example, the URL address may be processed using an MD5 encryption algorithm, to obtain an MD5 value corresponding to the URL address, as a processed string.
Further, the terminal 10 and the proxy gateway 20 may agree on a public key and a private key, and perform a first conversion process on the URL address, thereby obtaining a processed string.
As can be seen from the above technical solutions, the present embodiment provides a specific processing manner of the first conversion process, specifically, encryption processing may be performed, where encryption algorithms have multiple types. After the encryption processing, the character strings with different lengths can be converted into character strings with uniform lengths, so that the terminal 10 can be spliced conveniently, and the proxy gateway 20 can recognize the processed character strings conveniently, so that the proxy gateway 20 can better send the URL address to the service server 30.
Next, an embodiment of the present application will be further described with respect to a proxy gateway 20, which is a method for accessing public network resources under an IPTV private network according to the present application.
The proxy gateway 20 has been described above as being capable of performing the second conversion processing on the processed character string and acquiring the URL address after the second conversion processing. Further, the process of the proxy gateway 20 performing the second conversion processing on the processed character string and acquiring the URL address after the second conversion processing will be described in detail below.
In some embodiments of the present application, the processed string may include a first string and a second string, where the first string is the string after the first conversion, and the second string is the string that is not converted.
Specifically, when the terminal 10 performs the first conversion process only on the domain name in the URL address, the domain name after the first conversion process is used as the first character string, and the portion of the URL address other than the domain name is used as the second character string. Based on this, the terminal 10 splices the first character string and the second character string to obtain a processed character string.
On this basis, the processed character string may include a first character string and a second character string, the proxy gateway 20 performs a second conversion process on the first character string to obtain a domain name of the URL address, and splices the end of the domain name into the second character string, so that the URL address may be obtained.
The second conversion process is the inverse process of the first conversion process, and the first conversion process and the second conversion process are the processing modes agreed by the terminal 10 and the proxy gateway 20.
In some embodiments of the present application, the processed string may be a third string after the URL address is integrally converted. On this basis, the proxy gateway 20 may perform a second conversion process on the third string to obtain the URL address.
Specifically, when the terminal 10 performs the first conversion process on the entire URL address, the obtained processed character string is the third character string. On the basis, the second conversion processing can be performed on the third character string, and the URL address can be obtained.
The above technical solution introduces a processing mode capable of selecting different second conversion processing according to the difference of the processed character strings. Therefore, the time for accessing the public network resources under the IPTV private network can be reduced, and the public Internet can be better accessed to acquire the public network playing resources for playing.
Next, a processing mode of the second conversion processing will be described in detail.
In some embodiments of the present application, the first conversion process may be an encryption process, and correspondingly, the second conversion process may be a decryption process.
The decryption processing mode comprises any one of the following steps: MD5 decryption algorithm, decryption Triple DES decryption algorithm, decryption IDEA decryption algorithm, skip jack decryption algorithm, RC4 decryption algorithm, RC5 decryption algorithm.
For example, if the first conversion process is an MD5 encryption algorithm, the second conversion process may be an MD5 decryption algorithm as an inverse of the first conversion process. For example, if the terminal 10 encrypts the URL address, the processed character string is obtained as the MD5 value. On this basis, the proxy gateway 20 decrypts the MD5 value by using an MD5 decryption algorithm to obtain the URL address.
As can be seen from the above technical solutions, the present embodiment provides a specific processing manner of the second conversion process, where the second conversion process may be a decryption process based on the first conversion process being an encryption process. The decryption algorithm may be various, and corresponds to the first conversion process. After decryption processing, the encrypted character string is converted into the corresponding URL address and sent to the service server 30.
Next, the present application will be described in detail by way of examples in specific scenarios.
The explanation will be given taking as an example that the first conversion process is an MD5 encryption algorithm and the second conversion process is an MD5 decryption algorithm.
If the terminal 10 obtains that the proxy gateway service address is http://192.168.1.1 and/or the URL address is http:// abc.bd.cn/e/f.mp4.
Next, the present application will be described by taking an example of encrypting a domain name in a URL address.
At this time, the domain name in the URL address may be encrypted by using an MD5 encryption algorithm, that is, http:// 192.168.1.1/may be encrypted, so as to obtain an MD5 value corresponding to the domain name may be 80F3A86511B050CB344B1C8CD235A57B. The processed string may be found to be 80F3a86511B050CB344B1C8CD235a57B/e/f.mp4.
The processed character string can be spliced with the proxy gateway service address to obtain the service request address which is http://192.18/80F3A86511B050CB344B1C8CD235A57B/e/f.mp4.
After the proxy gateway 20 obtains the service request address, the processed character string 80F3a86511B050CB344B1C8CD235a57B/e/f.mp4 may be obtained.
On this basis, the proxy gateway 20 may perform a second conversion process on the MD5 value to obtain http:// abc.bd.cn/and splice with e/f.mp4, so as to obtain the URL address as http:// abc.bd.cn/e/f.mp4.
Next, the present application will be described by taking an example of encrypting the entire URL address.
