Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the present disclosure provides a resource transmission method, which may be specifically executed by a server as shown in fig. 1. The resource transmission method comprises the following steps of 101-103:
101. receiving a resource address acquisition request from the terminal equipment, wherein the resource address acquisition request at least comprises a resource identifier of a resource to be acquired.
The resource to be acquired is an image resource required by the terminal device, and the image resource may be, for example, a picture, a video, or the like. The resource address obtaining request may include a resource identifier of the resource to be obtained, and is used to enable the server to determine the resource address corresponding to the resource identifier of the resource to be obtained according to the resource identifier of the resource to be obtained.
In practical applications, the resource address obtaining request may further include a terminal device identifier, so that the server may distinguish different terminal devices according to the terminal device identifier.
102. According to the resource identifier, determining a resource address corresponding to the resource identifier from a resource list; wherein, the resource list at least comprises the corresponding relation between the resource identifier and the resource address.
In this step, the server determines, according to the resource identifier in the resource address acquisition request, which acquisition device the resource to be acquired corresponding to the resource identifier is stored on from the resource list, or which acquisition device the resource to be acquired can be acquired through. That is, the server determines the resource address where the resource to be acquired is stored, or may acquire the resource address of the resource to be acquired.
For example, the resources to be acquired in the resource list include: a first unit of language at a grade, a lesson explanation; a first secondary math unit for testing questions and answers; eight-grade english second unit, lesson explanation. The resource addresses in the resource list include: http:// www.1:. com/1:. html, http:// www.1:. com/2:. html, http:// www.2:. com/3:. html, as shown in the following table:
| resource to be acquired | Collecting resource addresses on a device |
| First unit of language, lesson explanation in one grade | http://www.1**.com/1**.html |
| First unit of second grade mathematics, test questions and answers | http://www.1**.com/2**.html |
| Eight-grade English second unit, text explanation | http://www.2**.com/3**.html |
Specifically, the resource address may be a resource link address of the resource to be acquired on the acquisition device, or the resource address may be an enabling address of the acquisition device that acquires the resource to be acquired.
In practical application, the server may also perform maintenance and update on the resource list. For example, when an image resource is newly added to a certain acquisition device, or a resource address corresponding to an original image resource is changed or deleted, the server updates the resource list in time.
103. And sending the resource address to the terminal equipment.
After determining the resource address corresponding to the resource to be acquired, the server sends the resource address to the terminal device, so that the terminal device directly accesses the resource address to acquire the resource to be acquired.
In a feasible implementation manner, the server may also perform classification management on the received image resources, and return a certain type of image resources and a corresponding resource address to the terminal device when the terminal device requests it. Specifically, the server receives image resources and resource identifiers from each acquisition device; and the category of the image resource is used as an index, and the corresponding image resource, the resource address and the resource identifier are stored to generate the resource list.
The resource address acquisition request received by the server may further include information of a resource category to be acquired. After receiving the resource address acquisition request containing the resource category information to be acquired, the server sends all image resources and resource addresses corresponding to the resource category information in the resource list to the terminal equipment in a list form according to the resource category information to be acquired. So that the terminal device is presented to the user.
Further, in this embodiment, the server may also manage the authority of the user to acquire the image resource. In a feasible manner, the level of the user can be predefined according to the role of the user, different levels correspond to different permissions, and the server can respond to the resource address acquisition request of the user at the level according to the permissions corresponding to the different levels and send the resource address to the user at the level.
For example, if the user level is one year level, the resource address of the image resource corresponding to the one year level can be acquired from the server. If the level of the user is upgraded to the second-grade level, the resource address of the image resource corresponding to the second-grade level can be acquired from the server. Or, if the user level is primary, the resource address of the image resource in the primary range corresponding to the primary can be obtained from the server; if the user level is a middle level, the resource address of the image resource in the middle level range corresponding to the middle level can be acquired from the server. This embodiment is not particularly limited thereto.
According to the resource transmission method provided by the embodiment of the disclosure, the server sends the resource address of the resource to be acquired on the acquisition device, which is required by the terminal device, to the terminal device, so that the terminal device directly accesses the image resource on the acquisition device through the resource address, and the problem of source code leakage of the image resource in the transmission process is avoided.
The embodiment of the present disclosure provides a resource transmission method, as shown in fig. 2, the resource transmission method may be specifically executed by a terminal device, and the terminal device may be, for example, a Personal Computer (PC), a zero terminal, a thin terminal, a mobile terminal, and the like.
Specifically, the resource transmission method comprises the following steps 201-204:
201. sending a resource address acquisition request to a server; the resource address acquisition request at least comprises a resource identifier of the resource to be acquired.
Wherein, the resource identifier is used for uniquely identifying the resource to be acquired. The resource to be acquired is displayed to the user through a display screen of the terminal device in the form of an information list, for example, the information list includes titles of the image resources, and the user sends a resource address acquisition request for the resource to be acquired (the image resource desired to be acquired) by clicking the title of the image resource desired to be acquired in the information list.
It should be noted that, the user may click the title of the image resource desired to be acquired in the information list through a mouse, may click the title of the image resource desired to be acquired in the information list on a touch display screen through a finger/an electronic pen, and may select the title of the image resource desired to be acquired in the information list through a voice instruction. And is not particularly limited herein.
In practical application, the terminal device stores a mapping relationship between the image resource and the resource identifier, and the terminal device can determine the resource identifier corresponding to the resource to be acquired according to the mapping relationship between the image resource and the resource identifier.
202. A resource address is received from the server.
The resource address may be a resource link address of the resource to be acquired on the acquisition device, or the resource address may be an enabling address of the acquisition device that acquires the resource to be acquired.
In practical application, if the resource to be acquired is stored in the acquisition device, the resource address received by the terminal device is the resource link address returned by the server. If the resource to be acquired needs to be acquired by the acquisition equipment in real time, correspondingly, the resource address received by the terminal equipment is the resource starting address of the acquisition equipment returned by the server.
203. And sending a resource acquisition request to acquisition equipment corresponding to the resource address according to the resource address.
Specifically, when the resource address is a resource link address, the terminal device may send a resource acquisition request to the acquisition device corresponding to the resource link address according to the resource link address, so that the acquisition device returns the image resource stored and compressed by the acquisition device.
When the resource address is a resource starting address, the terminal device may send a resource obtaining request to the acquisition device corresponding to the resource starting address according to the resource starting address, so as to trigger the acquisition device to acquire the image resource in real time, and return to the terminal device after compressing the image resource acquired in real time.
204. And receiving the compressed image resource from the acquisition device.
And the acquisition equipment encodes and compresses the image resources and then sends the image resources to the terminal equipment. The image resource is transmitted in the form of the video image frame after compression coding in the transmission process, so that the problem of source code leakage in the transmission process of the image resource in the prior art is effectively avoided.
Further, the resource address acquisition request sent by the terminal device to the server may further include resource category information to be acquired; correspondingly, the terminal equipment can receive all image resources and resource addresses which are sent by the server and correspond to the resource type information; and all the image resources and resource addresses are displayed in a list form.
After this step, after receiving the compressed image resource, the terminal device may decompress the compressed image resource, and display the decompressed image resource to the user.
It should be noted that, in the prior art, there may be problems such as an old version and an inability to update in time of an image resource stored in a server, or there may also be problems such as inconsistency of player versions and an inability to parse a file format when a terminal device is required to operate or play the image resource, and a user needs to install a plurality of players and parsers for different file formats. In this embodiment, the terminal device only needs to decode the received resource information, and there are no problems that the versions of the players are inconsistent, the file format cannot be analyzed, and the like, which not only facilitates the use of the user, but also reduces the requirement for the hardware configuration of the terminal device, thereby achieving the light weight of the terminal device and reducing the cost.
According to the resource transmission method provided by the embodiment of the disclosure, after the terminal device acquires the resource address of the image resource to be acquired from the server, the compressed image resource is acquired from the acquisition device according to the resource address, and the image resource is transmitted in the form of the compressed video image frame, so that the problem of source code leakage of the image resource in the transmission process can be effectively avoided.
The embodiment of the present disclosure provides a resource transmission method, as shown in fig. 3, the resource transmission method may be specifically executed by a collection device, where the collection device refers to a device that stores or collects resources, and the collection device may be a server, a camera, and the like, for example.
Specifically, the resource transmission method comprises the following steps 301-304:
301. receiving a resource acquisition request from terminal equipment; the resource acquisition request at least comprises a resource identifier of the resource to be acquired.
302. And acquiring the image resource corresponding to the resource identifier according to the resource identifier.

303. And compressing the image resources according to a preset compression mode.
After the acquisition equipment acquires/acquires the image resource in real time, the acquisition equipment uses a preset compression mode to encode and compress the image resource so as to prevent the image resource from leaking source codes in the transmission process. Wherein, the preset compression mode may include: a baseline coding compression mode or a progressive coding compression mode.
304. And sending the compressed image resource to the terminal equipment.
According to the resource transmission method provided by the embodiment of the disclosure, after the acquisition device receives the resource acquisition request sent by the terminal device, the acquisition device compresses the resource to be acquired required by the terminal device and then sends the compressed resource to the terminal device, so that the problem of source code leakage of image resources in the transmission process can be effectively avoided.
