The multimedia resource cache server is used for caching the multimedia resources sent by the multimedia resource storage server, and the multimedia resources cached in the multimedia resource cache server can be resources which have been requested by other terminals or the terminal.
The following describes a resource acquisition method provided by the present application with reference to specific embodiments. Fig. 3 is a first schematic flow diagram of the resource obtaining method provided in the present application, where an execution main body of the method flow shown in fig. 3 may be a resource obtaining device, the resource obtaining device is an adaptation server, and the adaptation server may be implemented by any software and/or hardware. As shown in fig. 3, the resource obtaining method provided in this embodiment may include:
s301, receiving a resource request sent by a terminal, wherein the resource request comprises: the network type of the terminal, the type of the target resource requested by the terminal.
The user can obtain the required resource through the terminal, and correspondingly, the terminal can send a resource request to the adaptation server. It should be understood that the process of the terminal sending the resource request to the adaptation server may be the same as the process of the terminal sending the resource request to the server in the prior art, and details are not described herein.
The resource request of the embodiment of the application may include: the network type of the terminal, the type of the target resource requested by the terminal. The network type of the terminal is used for indicating whether the terminal belongs to an intranet terminal or an extranet terminal. It should be understood that the intranet and the extranet in this embodiment are relative to the network where the adaptation server, the multimedia resource cache server, and the multimedia resource storage server are located.
The type of the target resource requested by the terminal may be static resources such as characters and pictures, or dynamic resources such as videos and animations, or resources including the static resources and the dynamic resources.
The following describes an applicable scenario in which the terminal sends a resource request to the adaptation server in this embodiment:
fig. 4 is a schematic diagram of a terminal interface change provided in the present application. Optionally, a plurality of resources or only a target resource may be displayed on the terminal. As shown in the example of the interface 401 of fig. 4, a plurality of resources, resource 1 and resource 2, are displayed on the interface. When a user needs resource 1, this resource 1 is a target resource. The user can select the resource 1 by clicking or other operation modes to trigger the terminal to send a resource request to the adaptation server. It should be understood that the resource request includes: the type of resource 1 and the network type of the terminal.
S302, a target server is determined according to the network type of the terminal and/or the type of the target resource, the target server is a multimedia resource cache server or a multimedia resource storage server, the multimedia resource cache server is used for caching the multimedia resource sent by the multimedia resource storage server, and the multimedia resource storage server is used for storing a plurality of multimedia resources.
After receiving the resource request, the adaptation server may determine the target server according to the network type of the terminal and/or the type of the target resource in the resource request. The target server is a server accessed by the terminal, namely a server for acquiring target resources. It should be understood that the terminal accessing the target server means that the adaptation server forwards the resource request to the target server so that the target server returns the target resource.
The target server in this embodiment is a multimedia resource cache server or a multimedia resource storage server. That is, in this embodiment, the adaptation server determines that the target server is a multimedia resource cache server or a multimedia resource storage server according to the network type of the terminal and/or the type of the target resource. The multimedia resource cache server is used for caching multimedia resources sent by the multimedia resource storage server, and the multimedia resource storage server is used for storing a plurality of multimedia resources. Optionally, the multimedia resource cache server may periodically clean the cached multimedia resources, that is, delete the cached multimedia resources before the current time preset time period, so as to ensure timeliness of the cached multimedia resources.
Optionally, in this embodiment, the adaptation server stores a preset rule for determining the target server, where the preset rule may be used to indicate a correspondence between a network type of the terminal and the target server, or a correspondence between a type of the target resource and the target server, or a correspondence between a network type of the terminal and a type of the target resource and the target server. According to the corresponding relation, the network type of the terminal in the resource request and/or the type of the target resource, the corresponding target server can be determined.
Optionally, for the intranet terminal, which is a terminal authorized by the intranet, the intranet terminal can directly access the multimedia resource storage server, and the problem of access security does not exist. Therefore, the target server corresponding to the intranet terminal can be set as the multimedia resource storage server. Correspondingly, the target server corresponding to the external network terminal can be set as a multimedia resource cache server, namely, the external network terminal obtains resources by accessing the multimedia resource cache server for caching the multimedia resources, so that potential safety hazards caused by the fact that the external network terminal directly accesses the multimedia resource storage server are avoided.
Optionally, for dynamic resources such as videos and animations, the dynamic resources need to occupy a larger bandwidth in the transmission process and have a long transmission time, so that a target server corresponding to the dynamic resources can be set as a multimedia resource cache server. Correspondingly, for static resources in transmission time periods such as static resources of characters, pictures and the like, a target server corresponding to the static resources can be set as a multimedia resource storage server.
In this embodiment, in order to improve access security, if the network type of the terminal in the resource request is an external network terminal, it is determined that the target server is a multimedia resource cache server. Correspondingly, in this embodiment, in order to improve the resource obtaining efficiency, if the type of the target resource in the resource request is a dynamic resource, it is determined that the target server is a multimedia resource cache server. That is, in this embodiment, when the network type of the terminal in the resource request is an external network terminal, or the type of the target resource is a dynamic resource, the terminal obtains the corresponding resource by accessing the multimedia resource cache server.
In addition, in order to improve the resource obtaining efficiency in this embodiment, if the terminal in the resource request is an intranet terminal and the type of the target resource is a static resource, it is determined that the target server is a multimedia resource storage server, that is, when the resource requested by the intranet terminal is a static resource, the static resource can be directly obtained by accessing the multimedia resource storage server, so that the real-time property of resource obtaining is ensured.
The target server in this embodiment is a multimedia resource cache server or a multimedia resource storage server. In this embodiment, the server for caching the resource and the server for storing the resource may be distinguished according to the type of the resource.
Optionally, in this embodiment, if the type of the target resource is a static resource and the dynamic resource is a video, correspondingly, the multimedia resource cache server that caches the video is a video streaming server, and the multimedia resource storage server that stores the video is a video storage server.
Optionally, in this embodiment, if the type of the target resource is a static resource and the static resource is a picture, correspondingly, the multimedia resource caching server that caches the picture is a picture proxy server, and the multimedia resource storage server that caches the picture is a picture storage server. The picture proxy server may be an Nginx picture proxy server.
Correspondingly, when the network type of the terminal in the resource request is the external network terminal, the corresponding target server is the multimedia resource cache server. If the type of the target resource in the resource request is a video, the corresponding multimedia resource cache server is a video streaming media server, and if the type of the target resource in the resource request is a picture, the corresponding multimedia resource cache server is a picture proxy server.
Correspondingly, when the network type of the terminal in the resource request is an intranet terminal and the type of the target resource is a picture, the corresponding target server is a multimedia resource storage server, and the multimedia resource storage server is a picture storage server. When the network type of the terminal in the resource request is an intranet terminal and the type of the target resource is a video, the corresponding target server is a multimedia resource cache server, and the multimedia resource cache server is a video streaming media server.
S303, the resource request is forwarded to the target server.
In this embodiment, after the adaptation server determines the target server, the resource request sent by the terminal may be forwarded to the corresponding target server, so that the target server returns the target resource to the adaptation server according to the resource request, and further the adaptation server returns the target resource to the terminal.
It should be understood that the resource request includes an identification of the target resource. The identifier of the target resource is used to distinguish other resources, and may be the name, publication date, etc. of the target resource. For example, if the target resource is article 1, the identifier corresponding to the target resource may be the name "XXX" of article 1, or the author and publication date of article 1.
In this embodiment, after receiving the resource request, the target server may obtain the target resource from the cached resource or the stored resource according to the identifier of the target resource.
Optionally, when the multimedia resource cache server in this embodiment receives the resource request, it may determine whether the target resource is a resource requested for the first time according to the identifier of the target resource. It should be understood that the target resource is the first requested resource and refers to: the multimedia resource cache server receives a resource request, wherein the resource request can be sent by the terminal or sent by other terminals, and the identifier of the target resource appears for the first time in the resource request. I.e. when the target resource requested by the terminal is not the first requested resource, it indicates that the target resource was previously requested by the terminal or other terminals.
When the target resource is a resource requested for the first time, the multimedia resource cache server determines that the corresponding target resource is not stored in the target resource, and forwards the resource request to the multimedia resource storage server, so that the multimedia resource storage server sends the stored target resource to the multimedia resource cache server, and the multimedia cache server caches the target resource after receiving the target resource.
When the target resource is not the resource requested for the first time, the multimedia resource cache server queries that the target resource is not available in the cached resources (wherein although the target resource is cached by the multimedia cache server, the target resource is deleted during periodic cleaning), and if the target resource is not available, the multimedia resource cache server also needs to forward the resource request to the multimedia resource storage server, and the target resource is acquired by adopting the same method.
When the target resource is not the resource requested for the first time, the multimedia resource cache server inquires the target resource in the cached resources, and then sends the target resource to the adaptation server.
S304, receiving the target resource sent by the target server and sending the target resource to the terminal.
In this embodiment, the target server may obtain the target resource according to the resource request, and then send the target resource to the adaptation server. Correspondingly, the adaptive server receives the target resource sent by the target server and sends the target resource to the terminal.
Optionally, when the dynamic resource in the resource request is a video, the transmission time corresponding to the video is long. In the prior art, a terminal can play a video on the premise of receiving the video, so that the waiting time of a user is long and the user experience is poor.
In this embodiment, the video streaming media server may perform fragment processing on the video, and send the video fragment to the adaptation server, so that the adaptation server sends the video fragment to the terminal. Therefore, the terminal can play the received video after receiving the fragment video corresponding to the video, and the terminal does not need to wait for the whole video to be completely received and played, so that the user experience is improved.
Correspondingly, if the video is not cached in the video streaming media server, the video streaming media server can receive the video sent in a slicing mode to the video storage server, and further cache the video in a slicing mode, and further send the video can be achieved.
Optionally, the resource request in this embodiment may further include a display type of the terminal, where the display type of the terminal is used to indicate the resolution and the size of the terminal display resource. Optionally, the terminal may be an Android terminal, an IOS terminal, or a windows terminal, and different terminals have different resolutions, sizes, and the like for displaying the same target resource.
In this embodiment, before the adaptation server receives the target resource sent by the target server and sends the target resource to the terminal, the method may include: and processing the target resource according to the display type of the terminal to obtain the processed target resource. It should be understood that the processing may be processing for decreasing or increasing the resolution, increasing or decreasing the size of the target resource, so that the resolution and the size of the processed target resource are the same as those of the display resource of the terminal, so that the target resource more meets the requirement of the terminal.
