Detailed Description
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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The present application is described next with reference to 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 the embodiment of the present application, and as shown in fig. 1, the system architecture may include: terminal 10, proxy gateway 20, 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 can support playing the public network playing resource returned by the proxy gateway. Further, the user can perform various operations such as watching video, listening to music, and surfing the lecture on the TV side through the terminal 10.
The proxy gateway 20 and the service server 30 may be composed of a plurality of servers, wherein the proxy gateway 20 may be a server provided by a target application manufacturer or a server provided by an IPTV private network manufacturer.
What the present application needs to achieve is that the proxy gateway 20 can receive the play resource that is sent by the service server 30 and matches with the target service selected by the user, and send the play resource to the terminal 10, so that the terminal 10 can play the play resource.
Based on this, the present application can help the terminal 10 under the IPTV private network play the public network resource.
Based on the system architecture shown in fig. 1, fig. 2 shows an optional signaling flow of the method for accessing public network resources in an IPTV private network according to the embodiment of the present application.
Referring to fig. 2, the flow is specifically as follows:
step S110, the terminal 10 responds to an operation of a user selecting a target service under a target application on the terminal 10, and acquires a proxy gateway address and a uniform resource locator 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 may select the target service through an infrared remote control, or the user may select the target service through a key on the terminal 10.
When the application app which needs to access the public network broadcast 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 of the application app, and can write a URL address corresponding to a product service in a code corresponding to the service. When the installed application app performs a service update, 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, which is not limited in the present application.
The URL addresses corresponding to different services in the same application app may be different, and the domain names of the URL addresses in the same application app may be the same or different.
Based on this, after 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.
Step S120, the terminal 10 performs a first conversion process on the URL address to obtain a processed character string.
Specifically, the URL address may be subjected to the first conversion processing in various ways, and may be converted into a binary system, or may be converted into a decimal system.
And after the first conversion processing, the character string does not contain the domain name of the unprocessed URL address.
Step S130, the terminal 10 merges 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 is in the obtained service request address, namely the domain name of the proxy gateway exists.
Step S140, the terminal 10 calls the player to send 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.
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 may obtain the URL address after performing the second conversion processing on the processed character string.
Step S160, the proxy gateway 20 sends the URL address.
Specifically, the proxy gateway 20 sends the URL address to the service server 30, where 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 a public network broadcast resource corresponding to the URL address. After the service server 30 obtains the public network broadcast resource, the public network broadcast 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 that the target service also corresponds to the public network playing resource.
Step S180, the proxy gateway 20 sends the public network play resource.
Specifically, after receiving the public network broadcast resource, the proxy gateway 20 may send the public network broadcast resource to the terminal 10.
Step S190, the terminal 10 plays the public network play resource.
Specifically, after receiving the public network play resource, the player in the terminal 10 may play the public network play resource.
It can be seen from the foregoing technical solutions that, in the method for accessing public network resources under an IPTV private network provided in this embodiment, when a player in the terminal 10 has a requirement for playing a public network playing resource, the public network playing resource sent by the proxy gateway 20 and corresponding to a target service can be obtained, and the public network playing resource is played. Therefore, the method and the device can access the public Internet to obtain the public network playing resources and play under the IPTV private network.
Furthermore, the proxy service address and the URL address can be obtained from the target application, an IPTV operator does not need to perform routing configuration, DNS configuration or network transformation on an IPTV private network, any configuration change, setting and the like on the set top box is not needed, the safety risk of various configurations and unpredictable influence caused by misoperation are effectively reduced, the threshold of application access to the IPTV private network is greatly reduced, and the cost is low. In addition, additional operation or configuration is not required for a user, and the method is simple, convenient and easy to implement and convenient to popularize.
Next, the embodiment of the present application will further describe a method for accessing public network resources under an IPTV private network according to the present application from the perspective of the terminal 10.
It has been described above that the terminal 10 can perform the first conversion process on the URL address to obtain the processed character string. Further, the following describes in detail a process of the terminal 10 performing the first conversion processing on the URL address to obtain a processed character string.
Specifically, in some embodiments of the present application, the terminal 10 may perform a first conversion process on the whole URL address to obtain a processed character string.
Wherein the URL address is the entire URL address as a whole, 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 character string, and then concatenate a second character string except the domain name in the URL address at an end of the first character string to obtain a processed character 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 character string corresponding to the domain name. And then splicing the first character string and the access path to obtain a processed character string.
The above technical solution introduces two specific contents that can perform the first conversion processing, for example, the first conversion processing may be performed on the whole URL address, or the first conversion processing may be performed only on the domain name of the URL address, so that the corresponding processing mode may 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 processing is performed only on the domain name, so as to reduce the time for performing the first conversion processing 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 obtain the public network playing resources for playing.
Next, a processing manner 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 mode may include any one of the following: MD5 encryption algorithm, Triple DES encryption algorithm, IDEA encryption algorithm, Skipjack 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 also agree with a public key and a private key, and perform a first conversion process on the URL address, thereby obtaining a processed character string.
As can be seen from the foregoing technical solutions, the present embodiment provides a specific processing manner of the first conversion processing, which may specifically be encryption processing, where there are multiple encryption algorithms. After the encryption processing, the character strings with different lengths can be converted into character strings with uniform length, so that the terminal 10 can be spliced, and the proxy gateway 20 can identify the processed character strings, so that the proxy gateway 20 can better send the URL address to the service server 30.
Next, the embodiment of the present application will further describe a method for accessing public network resources under an IPTV private network in the present application from the perspective of the proxy gateway 20.
It has been described above that the proxy gateway 20 can perform the second conversion process on the processed character string and obtain the URL address after the second conversion process. Further, a process of performing the second conversion process on the processed character string and acquiring the URL address after the second conversion process by the proxy gateway 20 will be described in detail below.
In some embodiments of the present application, the processed character string may include a first character string and a second character string, where the first character string is a character string subjected to the first conversion, and the second character string is a character string not subjected to the conversion processing.
Specifically, after the terminal 10 performs the first conversion processing only on the domain name in the URL address, the domain name after the first conversion processing is used as the first character string, and the part of the URL address except 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 concatenates the second character string with the end of the domain name, 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 character string may be a third character string obtained by performing a first conversion process on the whole URL address. On this basis, the proxy gateway 20 may perform a second conversion process on the third string to obtain the URL address.
Specifically, after the terminal 10 performs the first conversion processing on the whole URL address, the obtained processed character string is the third character string. On this basis, the second conversion processing may be performed on the third string to obtain the URL address.
The above technical solution introduces a processing manner that can select different second conversion processing according to different 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 obtain the public network playing resources for playing.
Next, a processing manner 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 modes: MD5 decryption algorithm, decryption Triple DES decryption algorithm, decryption IDEA decryption algorithm, Skipjack decryption algorithm, RC4 decryption algorithm, RC5 decryption algorithm.
For example, the first conversion process is an MD5 encryption algorithm, and the second conversion process is an inverse process of the first conversion process and may be an MD5 decryption algorithm. For example, if the terminal 10 encrypts the URL address, the obtained character string is an 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 foregoing technical solutions, this embodiment provides a specific processing manner for the second conversion processing, and the second conversion processing may be decryption processing on the basis that the first conversion processing is encryption processing. There may be a plurality of decryption algorithms corresponding to the first conversion process. After the decryption process, the encrypted character string may be 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 an example in a specific scenario.
The explanation is given taking an example in which the first conversion process is the MD5 encryption algorithm and the second conversion process is the MD5 decryption algorithm.
If the terminal 10 obtains that the proxy gateway service address is http:// 192.168.1.1/and 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 MD5 encryption algorithm may be used to encrypt the domain name in the URL address, that is, http:// 192.168.1.1/may be encrypted, and the MD5 value corresponding to the obtained domain name may be 80F3a86511B050CB344B1C8CD235a 57B. The processed string may be 80F3A86511B050CB344B1C8CD235A 57B/e/f.mp4.
The processed character string can be spliced with the proxy gateway service address to obtain the service request address of http://192.18/80F3A86511B050CB344B1C8CD235A 57B/e/f.mp4.
When the proxy gateway 20 obtains the service request address, the processed string 80F3A86511B050CB344B1C8CD235A57B/e/f.mp4 can 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 concatenate with e/f.mp4, so as to obtain the URL address of http:// abc.bd.cn/e/f.mp4.
Next, the present application will be described by taking an example of encrypting the entire URL address.
