As shown in fig. 5, the gateway apparatus 400 includes: at least one of modem 410, communicator 420 controller 430, memory, power supply, user interface.
In some embodiments, when gateway device 400 receives an original content request sent by a terminal device through communicator 420, controller 430 judges whether a request matching library includes a redirected content request corresponding to the original content request or not through gateway device 400, and when the request matching library includes the redirected content request corresponding to the original content request, sends the redirected content request corresponding to the original content request to the terminal device through communicator 410, so that the terminal device obtains response content corresponding to the redirected content request from a content distribution network based on the redirected content request corresponding to the original content request; when the request matching library does not include the redirected content request corresponding to the original content request, the response content corresponding to the original content request is acquired from the content server through the communicator 410, and then the acquired response content corresponding to the original content request is forwarded to the terminal device through the communicator 410.
In some embodiments, when the gateway device 400 obtains the response content corresponding to the original content request from the content server through the communicator 410, the gateway device 400 further determines, through the controller 430, whether the response content corresponding to the original content request meets the condition of caching to the CDN (preset condition), and if the response content corresponding to the original content request meets the condition of caching to the CDN, caches the response content corresponding to the original content request to the CDN, generates a redirected content request corresponding to the original content request, and adds the redirected content request corresponding to the original content request to the request matching library, so that when the same or similar content request sent by the terminal device is subsequently received, the redirected content request corresponding to the original content request is sent to the terminal device, so that the terminal device obtains the response content corresponding to the redirected content request from the content distribution network based on the redirected content request corresponding to the original content request.
In some embodiments, the implementation manner of the gateway device 400 to determine, through the communicator 410, whether the response content corresponding to the original content request meets the condition of caching to the CDN may include: recursively acquiring resource files of each level of the response content, and generating a resource file set corresponding to the response content; determining whether each resource file in the resource file set can be cached to the content distribution network according to the attribute of each resource file in the resource file set; if all the resource files in the resource file set can be cached in the content distribution network, determining that the response content meets the preset condition; and if one or more resource files in the resource file set can not be cached in the content distribution network, determining that the response content does not meet the preset condition. That is, whether each resource file in the response content corresponding to the original content request accords with the condition of caching to the CDN is determined, if all the resource files accord with the condition of caching to the CDN, the response content corresponding to the original content request is determined to accord with the condition of caching to the CDN, and if one or more resource files do not accord with the condition of caching to the CDN, the response content corresponding to the original content request is determined to not accord with the condition of caching to the CDN.
In some embodiments, the attributes of the resource file include the business scenario of the resource file. The gateway device 400 determines whether the resource file meets the condition of caching to the CDN, including: determining whether the service scene of each resource file in the resource file set belongs to a preset service scene; if the service scene of the first resource file in the resource file set does not belong to the preset service scene, determining that the first resource file can be cached to the content distribution network; and if the service scene of the second resource file in the resource file set belongs to the preset service scene, determining that the second resource file cannot be cached in the content distribution network. In actual use, service scenes of all resource files can be preconfigured, and service scenes which are unsuitable for buffering to the CDN, such as a user-related service scene, a timing operation service scene, an intelligent recommendation service scene and the like, are configured as preset service scenes, so that uploading of the resource files which are unsuitable for buffering to the CDN, such as the user-related service scene, the timing operation service scene, the intelligent recommendation service scene and the like, to the CDN is avoided.
In some embodiments, the implementation manner of the gateway device 400 to generate the redirected content request corresponding to the original content request includes: after caching response content corresponding to the original content request to the content distribution network, receiving a cache address of the response content corresponding to the original content request sent by the content distribution network; and generating a redirection content request corresponding to the original content request according to the cache address. That is, the cache address of the response content corresponding to the original content request may be used as the redirected content request corresponding to the original content request.
In some embodiments, to avoid excessive data in the request matching library, the redirected content requests in the request matching library are valid, and redirected content requests that exceed the valid are purged from the request matching library. In some embodiments, the manner in which redirected content requests that exceed the validity period are cleared includes: when the redirected content request corresponding to the original content request is added into the request matching library, starting timing; and deleting the redirected content request corresponding to the original content request from the request matching library when the timing duration reaches the preset duration. Because the redirected content request exceeding the validity period is cleared from the request matching library, corresponding response data cached in the CDN is also invalidated, and timely clearing of the invalidation data cached in the CDN can improve the cache utilization rate of the CDN, so that the gateway device further deletes the response content corresponding to the original content request from the cache of the content delivery network after deleting the redirected content request corresponding to the original content request from the request matching library.
In some embodiments, the implementation manner of adding the redirected content request corresponding to the original content request to the request matching library by the gateway device 400 includes: performing generalization processing on request parameters in the original content request to obtain a generalized content request corresponding to the original content request; establishing a corresponding relation between the generalized content request and the redirected content request; and adding the corresponding relation to the request matching library. In response, the gateway device 400 may further perform generalization processing on the request parameters in the original content request before determining whether the request matching library includes the redirected content request corresponding to the original content request. The probability of finding the corresponding redirected content request can be improved by generalizing the request parameters in the original content request, so that the pressure and the calculation cost of the server are reduced.
Fig. 6 is a schematic flow chart illustrating a content distribution method according to an embodiment of the present application, and as shown in fig. 6, the content distribution method according to the embodiment of the present application includes the following steps:
s601, the terminal equipment sends an original content request to the gateway equipment.
Correspondingly, the gateway device receives an original content request sent by the terminal device.
In some embodiments, the implementation of the terminal device sending the original content request to the gateway device may include: the terminal equipment responds to the user operation to determine the user interface to be displayed, and sends an original content request to the gateway equipment according to the display content of the user interface to be displayed. For example: when the user operates to start the operation of the television, the television can determine the home page of the television of the user interface to be displayed, and further display content with the home page sends an original content request to the gateway equipment.
In some embodiments, the original content request may be a user request for interface data.
S602, the gateway equipment judges whether a request matching library comprises a redirected content request corresponding to the original content request.
In some embodiments, the request matching library may store the correspondence between the original content request and the redirected content request in the form of a correspondence table, and determine whether the redirected content request corresponding to the original content request is included in the request matching library by determining whether the original content request is included in the request matching library. For example, when the request matching library stores the correspondence between the original content request and the redirected content request in the form of a correspondence table, the storage content in the request matching library may be as shown in the following table 1:
TABLE 1
In some embodiments, both the original content request and the redirected content request may be uniform resource locators (Uniform Resource Locator, URLs).
In the above step S602, if the gateway device determines that the request matching library includes a redirected content request corresponding to the original content request, the following steps S603 to S606 are performed.
S603, the gateway equipment acquires a redirected content request corresponding to the original content request according to the request matching library.
S604, the gateway equipment sends a redirection content request corresponding to the original content request to the terminal equipment.
Correspondingly, the terminal equipment receives a redirection content request corresponding to the original content request sent by the gateway equipment.
S605, the terminal equipment sends a redirection content request corresponding to the original content request to a content distribution network.
Correspondingly, the content distribution network receives a redirection content request corresponding to the original content request sent by the terminal equipment.
S606, the content distribution network sends response content corresponding to the redirection content request to the terminal equipment.
Correspondingly, the terminal equipment receives response content corresponding to the redirection content request sent by the content distribution network.
In some embodiments, the buffer data of the content distribution network has a validity period, and when the buffer data of the content distribution network exceeds the validity period, the data exceeding the validity period is deleted from the buffer of the content distribution network, so the implementation of the step S606 (the content distribution network sends the response content corresponding to the redirecting content request to the terminal device) may include the following steps a to e:
and a step a of determining whether the response content corresponding to the redirection content request is out of date.
In the step a, if it is determined that the response content corresponding to the redirection content request is not expired, the following steps b and c are executed.
And b, reading response content corresponding to the redirection content request from the cache.
And c, sending response content corresponding to the redirection content request to the terminal equipment.
In the step a, if it is determined that the response content corresponding to the redirection content request has expired, the following steps d and e are executed.
And d, acquiring response content corresponding to the redirected content request from the content server.
And e, sending response content corresponding to the redirection content request to the terminal equipment.
To this end, the terminal device acquires the response content from the content distribution network.
In the above step S602, if the gateway device determines that the request matching library does not include the redirected content request corresponding to the original content request, the following steps S607 to S609 are performed.
S607, the gateway device sends the original content request to the content server.
Correspondingly, the content server receives the original content request sent by the gateway device.
And S608, the content server sends response content corresponding to the original content request to the gateway equipment.
Correspondingly, the gateway equipment receives response content corresponding to the original content request sent by the content server.
S609, the gateway device sends response content corresponding to the original content request to the terminal device.
Correspondingly, the terminal equipment receives response content corresponding to the original content request sent by the gateway equipment.
So far, the terminal device acquires the response content from the content server.
According to the content distribution method provided by the embodiment of the application, when the gateway equipment receives an original content request sent by the terminal equipment, whether a request matching library comprises a redirection content request corresponding to the original content request is judged, when the request matching library comprises the redirection content request corresponding to the original content request, the redirection content request corresponding to the original content request is sent to the terminal equipment, so that the terminal equipment obtains response content corresponding to the redirection content request from a content distribution network based on the redirection content request corresponding to the original content request, and when the request matching library does not comprise the redirection content request corresponding to the original content request, the response content corresponding to the original content request is obtained from a content server and sent to the terminal equipment. The gateway device and the content distribution method provided by the embodiment of the application determine whether to send response content to the terminal device based on the content distribution network or the content server by judging whether the request matching library comprises the redirection content request corresponding to the original content request, so that the embodiment of the application can realize whether to send the response content to the terminal device based on the content distribution network in the content request granularity.
Referring to fig. 7, as an extension and refinement of the embodiment shown in fig. 6, after step S608 (the content server transmits the response content corresponding to the original content request to the gateway device) on the basis of steps S601 to S609 shown in fig. 6, the content distribution method provided by the embodiment of the present application further includes the steps of:
s701, the gateway equipment judges whether the response content meets a preset condition.
That is, the gateway device determines whether the response content acquired from the content server satisfies the condition of caching to the content distribution network.
In some embodiments, the implementation manner of the step S701 (the gateway device determines whether the response content meets the preset condition) includes the following steps i to iii:
and step I, recursively acquiring resource files of each level of the response content, and generating a resource file set corresponding to the response content.
That is, the resource files of each hierarchy of the response content are recursively acquired, and all the acquired resource files are combined into a resource file set corresponding to the response content.
For example, referring to fig. 8, a display interface with a television set as the response content is shown in fig. 8. The response content comprises: [ navigation List ] the navigation List includes: navigation items: [ My ], [ preferably ], [ film xx ], [ VIP ], [ TV show ], [ child ], [ education ], [ K song ], wherein the [ education ] is the focus navigation item in the navigation items. Navigation items [ education ] include: the side bar navigation comprises sub navigation items [ one grade ], two grades ], three grades ], four grades, five grades, six grades and seven grades, wherein the one grade is a focus sub navigation item in the sub navigation items. The recommended resource file of the first grade comprises the following items of medium resource 1, medium resource 2, medium resource 3, medium resource 4, medium resource 5, medium resource 6 and medium resource 7. Abstracting the response content corresponding to the display interface shown in fig. 8, the abstract diagram shown in fig. 9 may be obtained, and further, the resource file data structure of the response content may be obtained as follows:
A resource file of each level of response content corresponding to the display interface shown in fig. 8 is recursively acquired, and a resource file set corresponding to the response content is generated as { [ navigation list }, [ my ], [ recommendation ], [ movie xx ], [ VIP ], [ TV play ], [ juvenile ], [ education ], [ K song ], [ one-year ], [ two-year ], [ three-year ], [ four-year ], [ five-year ], [ six-year ], [ seven-year ], [ medium 1 ], [ medium 2 ], [ medium 3 ], [ medium 4 ], [ medium 5 ], [ medium 6 ], [ medium 7 }.
And step II, determining whether each resource file in the resource file set can be cached in the content distribution network according to the attribute of each resource file in the resource file set.
For example: for [ navigation list ]: determining whether the navigation list is recommended content or fixed content, wherein navigation items [ my ], [ recommended ], [ movie xx ], [ VIP ], [ TV play ], [ juvenile ], [ education ], [ K song ] under the navigation list are time-sharing operation content (content displayed in a designated time period), and if so, the navigation items cannot be cached to a content distribution network, otherwise, the navigation items cannot be cached to the content distribution network.
For another example: for the sub-navigation items of the navigation item [ education ], if each interface request is issued by [ one grade ], two grades ], three grades ], four grades ], five grades, six grades and seven grades, and the sequence is fixed, the [ education ] can be cached to the content distribution network.
In some embodiments, the attributes of any resource file include the business scenario of the resource file. The service scene of the resource file can be preconfigured by operation staff.

step 1, determining whether the service scene of each resource file in the resource file set belongs to a preset service scene.
The preset service scenario may include: the user related service scenario, the timing operation service scenario, the intelligent recommendation service scenario and the like are not suitable for the service scenario cached to the CDN.
In the above step 1, if the service scenario of the first resource file in the resource file set does not belong to the preset service scenario, the following step 2 is executed, and if the service scenario of the second resource file in the resource file set belongs to the preset service scenario, the following step 3 is executed.
And 2, determining that the first resource file can be cached to the content distribution network.
And step 3, determining that the second resource file cannot be cached in the content distribution network.
The first resource file and the first resource file are any resource file in the resource file set.
And if it is determined in the step ii that all the resource files in the resource file set can be cached in the content distribution network, executing the following step iii.
And III, determining that the response content meets the preset condition.
As described in the above example, when the resource file set is { [ navigation list ], [ my ], [ recommendation ], [ movie xx ], [ VIP ], [ television show ], [ child ], [ education ], [ K song ], [ one-grade ], [ two-grade ], [ three-grade ], [ four-grade ], [ five-grade ], [ six-grade ], [ seven-grade ], [ medium resource 1 ], [ medium resource 2 ], [ medium resource 3 ], [ medium resource 4 ], [ medium resource 5 ], [ medium 6 ], [ medium 7 ] }, each resource file can be cached to the content distribution network, the response content corresponding to the display interface shown in fig. 8 is determined to satisfy the preset condition.
And if the step II is that one or more resource files in the resource file set can not be cached in the content distribution network, executing the following step IV.
And IV, determining that the response content does not meet the preset condition.
That is, as long as any resource file in the resource file set cannot be cached in the content distribution network, it is determined that the response content does not meet the preset condition.
In some embodiments, a data identifier may be added in advance in the resource file, if the resource file may be cached in the content distribution network, a first identifier is added, if the resource file may not be cached in the content distribution network, a second identifier is added, after a resource file set corresponding to the response content is obtained, the data identifiers of the resource files in the resource file set are traversed, if the first identifiers are both the first identifiers, it is determined that the response content meets the preset condition, and if one or more second identifiers are provided, the response content does not meet the preset condition. Illustratively, the first identifier may be 1 and the second identifier may be 0.
