Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

In the related art, when external multimedia resources, especially cross-region resources are acquired, the problems of slow network speed, overtime acquisition and unstable network exist. Moreover, the access interfaces of the multimedia resources are different, the acquisition logic is disordered, and the multimedia resources cannot be quickly acquired. In addition, when acquiring the cross-region resources, the problem of overtime of acquiring the multimedia resources due to slow network speed is solved.

In view of the above, the present disclosure provides a multimedia resource acquiring method. In the method, a resource identifier of a resource to be detected is received. And if the resource identifier contains information indicating that the resource to be detected is the identifier of the third-party resource, storing the resource to be detected in a resource pool. And generating a global unique identifier for the resource to be detected, and sending the resource to be detected and the corresponding global unique identifier to each regional server, so that a detection person can access the resource to be detected through the regional server through a detection terminal.

According to the method, the third-party resources are stored in the resource pool, so that a detector does not need to access the server of each third-party resource through a plurality of interfaces when detecting the resources to be detected, and can access the resource pool through the unified interface, thereby avoiding the problem that the multimedia resources cannot be quickly obtained due to the fact that the access interfaces of the multimedia resources are different and the obtaining logic is disordered in the related technology. Moreover, in the embodiment of the disclosure, since the resource to be detected is sent to each regional server, the inspector can access the resource to be detected through each regional server, thereby avoiding the problem of slow acquisition speed or overtime acquisition caused by acquiring the multimedia resource across regions.

Fig. 1 is a schematic view of an application scenario of a multimedia resource obtaining method according to an exemplary embodiment of the present disclosure. The scene comprises the following steps: control center 101, resource pool 102, and regional server 103. The control center may be implemented by at least one server, and is configured to manage content of the resource pool, including downloading and other processing of the multimedia resource, and the control center 101 may further process a request of the detection terminal to download the multimedia resource.

In the embodiment of the present disclosure, the control center 101 receives a resource identifier of a resource to be detected. If the resource to be detected is determined to be the third-party resource according to the resource identifier, storing the resource to be detected in the resource pool 102, and generating a global unique identifier of the resource to be detected. Then, the control center 101 sends the resource to be detected and the corresponding global unique identifier to each regional server 103, so that the regional server can provide a near service for the detection terminal.

The resource pool 102 and the area server 103 may be a server cluster or a cloud computing center composed of one server or several servers.

Other embodiments of the present disclosure will be described below in conjunction with the drawings for the sake of understanding.

Referring to fig. 2, a flowchart of a multimedia resource obtaining method according to an exemplary embodiment of the disclosure may include the following steps:

step 201: and receiving a resource identifier of the resource to be detected.

In specific implementation, the resource identifier may include a resource address of the resource to be detected. The resource address may be an address pointing to a resource pool, or may also be an address pointing to a third party server. Or the resource identifier can also comprise the type of the resource to be detected, such as pictures, videos, audios and the like, so that the classified storage can be realized during the storage.

Step 202: determining whether the resource identifier contains information indicating that the resource to be detected is an identifier of a third-party resource, if so, executing step 203; otherwise, go to step 205.

Step 203: and storing the resource to be detected in a resource pool, and continuing to execute the step 204.

Step 204: and generating a global unique identifier of the resource to be detected, and continuing to execute the step 205.

Step 205: sending the resource to be detected and the global unique identifier to each regional server; and each area server is used for providing resources to be detected for the detection terminal in the corresponding area.

According to the method, the third-party resources are stored in the resource pool, so that the inspector does not need to access the server of each third-party resource through a plurality of interfaces when detecting the resources to be detected, and can access the resource pool through the uniform interfaces. And the resource to be detected is sent to the regional server, so that a detector can access the resource to be detected nearby through the regional server, and the access speed of the resource to be detected is improved.

When an inspector accesses to-be-detected resources, if the to-be-detected resources are too large, problems such as crash of a detection terminal and the like can be caused. For example, insufficient memory cannot be handled. In order to solve the above problem, the resource to be detected may be fragmented when the step 203 is executed.

In an optional embodiment, if the data volume of the resource to be detected is greater than or equal to a preset threshold, the resource to be detected is fragmented; and then storing the fragmentation result of the resource to be detected and the fragmentation identification corresponding to each fragmentation result. The preset threshold may be set by itself, for example, may be set to 200M, or 300M, etc. When the slices are divided, the number of the slices may be set, for example, the number of the slices is set to 10, 15, or the like. Then the resources to be detected may be evenly fragmented. For example, if the data volume of the resource to be detected is 300M and the number of the fragments is 15, the resource to be detected is divided into 15 fragments, and the data volume of each fragment result is 20M. Alternatively, the data size of each segment result may be set, for example, 15M or 20M. For example, the data volume of the resource to be detected is 200M, the data volume of each fragmentation result is 20M, and during fragmentation, the resource to be detected is divided into 10 fragments, and the data volume of each fragmentation result is 20M.

After the resource to be detected is fragmented, a fragmentation identifier may be allocated to each fragmentation result. And generating a global unique identifier of the resource to be detected according to the fragment identifier. For example, the resource to be detected is divided into 3 pieces, and the piece identifiers are respectively assigned as A1, a2 and A3, and then the globally unique identifier generated according to the piece identifiers is a 123. Where 123 can represent the number of slices simultaneously.

Or, a globally unique identifier a of the resource to be detected may be generated according to the fragment identifiers a1, a2, and A3.

According to the method, when the data volume of the resource to be detected is larger than the preset threshold value, the resource to be detected is fragmented, when the detection terminal accesses the resource to be detected, fragmentation access can be performed, all the resource to be detected does not need to be returned to the detection terminal, the problem that the detection terminal is crashed due to overlarge access resource is avoided, and the stability of the server is guaranteed.

Due to the fact that the storage resources of the resource pool are limited, in order to avoid repeated storage of the resources to be detected, duplicate checking detection can be carried out on the resources to be detected before the global unique identification is generated. In order to improve the accuracy of duplicate checking, the duplicate checking detection can be carried out on the resource to be detected for multiple times based on different methods. This will be explained below by taking two duplicate checks as an example.

Firstly, when the duplicate checking is carried out for the first time, the duplicate checking is carried out on the resource to be detected according to the message digest algorithm and the resource identification. It may be implemented to generate a digest of the resource identification according to the message digest algorithm MD 5. And searching the generated abstract of the resource identification in the abstract of the resource identification of the stored resource. If the same resource is found, determining that the duplicate checking detection result is that the same resource is found. And at the moment, acquiring the global unique identifier of the resource to be detected, and sending the global unique identifier and the resource to be detected to each regional server. If the same resource is not found, determining that the duplicate checking result is that the same resource is not found. And at the moment, downloading the resource to be detected according to the resource identifier, and performing second duplicate checking on the resource to be detected. Optionally, in implementation, a summary of the resource content of the resource to be detected may be generated according to MD 5. And searching the generated abstract of the resource content in the abstract of the resource content of the stored resource.

If the same resource is found, determining the secondary duplicate checking result as the same resource is found. And at the moment, acquiring the global unique identifier of the resource to be detected, and sending the global unique identifier and the resource to be detected to each regional server.

If the same resource is not found, determining that the same resource is not found as a secondary duplicate checking result. At this time, the resource to be detected is stored in the resource pool. Specifically, when the resource to be detected is stored, the format of the resource to be detected may be converted into an expected format. The desired format may be, for example, a format supported by the detection terminal such as MP 4. In a specific implementation, the desired format may be set as needed, for example, set to MP3, etc., and the disclosure is not limited in particular.

According to the method, the duplicate checking detection is carried out on the resources to be detected, so that the waste of the storage resources of the resource pool can be avoided. If the duplicate checking and detecting are performed on the resources to be detected, the duplicate checking and detecting are performed according to the content of the resources, which may result in an excessive calculation amount. Therefore, firstly, the resource to be detected is subjected to the first duplicate checking detection through the resource identifier, and whether the second duplicate checking detection is performed on the resource to be detected is determined according to the result of the first duplicate checking detection, so that the accuracy of the duplicate checking result can be ensured while the calculation amount in the duplicate checking process is reduced. In addition, the resources to be detected are converted into the expected format during storage, so that the problem that the multimedia resources cannot be displayed and frames cannot be extracted due to the format problem can be solved.

And after the first re-check is finished, when the resource to be detected is downloaded, if the downloading fails, the resource to be detected is downloaded again at intervals of gradient time. Alternatively, the number of gradient times may be set by itself, for example, to 5, 6, etc. when implemented. Further, the gradients may be set to be sequentially increased or may be set to be sequentially decreased. That is, the step-up time may be 1s, 2s, and 3s in sequence, and the step-down time may be set to 4s, 3s, and 2s, and the like, and the disclosure is not particularly limited.

And if the re-downloading fails in the last gradient time, sending information indicating that the resource to be detected is unavailable to a third-party server corresponding to the resource to be detected.

For example, the gradient time is 1s, 3s, and 5s, if the downloading is failed again in the last gradient time of 5s, it indicates that the resource to be detected is unavailable, and at this time, information indicating that the resource to be detected is unavailable is sent to the third-party server.

According to the method, when the downloading of the resource to be detected fails, the resource to be detected can be automatically retried, and the normal downloading of the resource to be detected is ensured. When the information cannot be normally downloaded, the third-party server is notified so that the third-party server can know the information, and a resource manager of the third party can timely perform corresponding processing so as to complete detection of the resource to be detected.

After an exemplary processing method of the resource to be detected of the present disclosure is introduced, a method for the detection terminal to access the resource to be detected is introduced next.

Referring to fig. 3, another flow diagram of a multimedia resource acquiring method in an exemplary embodiment of the present disclosure is shown, where the flow diagram is used to explain how to return a corresponding multimedia resource in response to a request of a detection terminal, and the method may include the following steps:

step 301: and receiving a browsing request of the resource to be detected, which is sent by a detection terminal, wherein the browsing request carries the global unique identifier of the resource to be detected and the start time information of the fragment to be browsed of the resource to be detected.

Specifically, if the start time information is a first specified value, the browsing request is automatically triggered by the detection terminal, and if the start time information is a second specified value, the browsing request is triggered by the operation of the detection terminal user.

The start time information here may be time, for example, 15s, 10s, or the like, or may also be start time information indicating a location of the resource, for example, indicating that the location of the resource is 20M, and the fragmentation result is a fragmentation result corresponding to 20M. Also, the first specified value may be time, e.g., the first specified value may be set to 0s, 10s, etc., or the first specified value may be a value indicating the location of the resource, e.g., the first specified value may be set to 0M, 10M, etc. Likewise, the second specified value may be a time greater than the first specified value, such as 15s, 20s, etc. Or the second specified value may be a value indicating the location of the resource that is greater than the first specified value, e.g., the second specified value may be set to 20M, 30M, etc.

In specific implementation, if the resource to be detected in the resource pool is stored in a fragmentation mode, fragmentation access is required when the resource to be detected is accessed. And the fragment access requires the inspector to send a plurality of browsing requests, which affects the inspector's inspection of the resource to be inspected. As such, the present disclosure employs HTTP range (Hyper Text Transfer Protocol request header) to mask the logic of the fragments. That is, after the server of the detection terminal accesses a piece of data of the resource to be detected, the inspector automatically sends a request for continuing to browse the next piece of data.

For example, the browsing request carries the global unique identifier a123, and the start time information is 15s, it can be known that the resource to be detected with the global unique identifier a needs to be acquired after the browsing request is received, and according to the start time information and the rule of the fragment, it can be known that the fragment result with the fragment identifier a2 needs to be acquired. And returns the slicing result with the slicing identification of A2 to the detection terminal.

For another example, the browsing request carries the global unique identifier B1234, and the start time information is 30M, it is known that the resource to be detected of the global unique identifier B needs to be acquired after the browsing request is received, and according to the start time information and the rule of fragmentation, it is known that the fragmentation result of the fragmentation identifier B3 needs to be acquired, and the fragmentation result of the fragmentation identifier B3 is returned to the detection terminal.

Step 302: and acquiring a resource path of the resource to be detected according to the global unique identifier.

Specifically, the generated global unique identifier includes a storage state and a resource address, and the resource address is obtained from the resource identifier of the resource to be detected in advance; and if the resource to be detected is successfully stored in the resource pool, the storage state is stored, and if the resource to be detected is not successfully stored in the resource pool, the storage state is not stored.

For example, if the storage status is stored, it may indicate that the resource to be detected is a third-party resource, and therefore, the resource address included in the resource identifier of the resource to be detected is the address of the third-party server. Therefore, a resource path of the resource to be detected in the local resource pool needs to be generated. In specific implementation, a URL (Uniform resource locator) path of the resource to be detected may be generated.

And if the storage state is not stored, acquiring the resource address in the global unique identifier as the resource path of the resource to be detected.

For example, if the storage status is not stored, it may indicate that the resource to be detected is a non-third-party resource, i.e., a resource of the resource pool. Therefore, the resource address included in the resource identifier of the resource to be detected is an address pointing to the resource pool.

Step 303: and under the resource path, acquiring the fragmentation result corresponding to the start time information carried in the browsing request according to the corresponding relation between the start time information of the resource to be detected and the fragmentation result of the resource to be detected.

Step 304: and returning the acquired fragmentation result to the detection terminal.

According to the method, the resource path pointing to the resource pool is generated for the third-party resource, and the purpose of providing a uniform interface for the terminal to be detected is achieved. In addition, the start time information is carried in the browsing request, so that the required data can be conveniently returned in a slicing mode, and the crash caused by insufficient memory of the detection terminal is avoided.

In specific implementation, when the resource path of the resource to be detected is generated according to the global unique identifier and the storage path of the resource to be detected, a Content Delivery Network (CDN) address or a first URL address may be generated. And the first URL address is used for pointing to the resource pool or the area server where the detection terminal is located.

Optionally, determining a geographical area where the IP address of the publishing device of the resource to be detected is located, and determining a geographical area where the IP address of the detection terminal is located; if the geographic area where the IP address of the issuing equipment of the resource to be detected is located is the same as the geographic area where the IP address of the detection terminal is located, CDM is likely to be deployed in the area, and whether CDN is deployed in the geographic area where the IP address of the detection terminal is located can be further determined according to the corresponding relation between CDN and the geographic area where the IP address of the detection terminal is located. If a CDN is deployed, generating a CDN address of the resource to be detected according to the global unique identifier; if the CDN is not deployed, generating a first Uniform Resource Locator (URL) address of the resource to be detected according to the global unique identifier; and the first URL address is used for pointing to the resource pool or the area server where the detection terminal is located.

For example, CDN deployment areas such as city a, city B, city C, etc. The geographic area where the IP address of the resource to be detected is released is A city, and the geographic area where the IP address of the detection terminal is located is A city. Then, the geographic area where the IP address of the issued resource to be detected is the same as the geographic area where the IP address of the detection terminal is. At this time, it is determined that the CDN is deployed in city a, and a CDN address is generated according to the global unique identifier.

For another example, the geographic area where the IP address of the resource to be detected is released is city D, and the geographic area where the IP address of the detection terminal is located is city D. Then, the geographic area where the IP address of the issued resource to be detected is the same as the geographic area where the IP address of the detection terminal is. At this time, if it is determined that the CDN is not deployed in city D, the first URL address is generated according to the global unique identifier.

Optionally, in implementation, if the D city deploys the regional server, the first URL address points to the regional server. If the D city does not deploy the regional server, the first URL address is an address pointing to the resource pool.

If the geographic area where the IP address of the resource to be detected is issued is different from the geographic area where the IP address of the detection terminal is, whether the detection terminal is served by a corresponding regional server is further confirmed, and whether the regional server is deployed in the geographic area where the IP address of the detection terminal is can be determined.

If a regional server is deployed in the geographic region where the IP address of the detection terminal is located, generating a second URL address of the resource to be detected according to the global unique identifier, wherein the second URL address is used for pointing to the regional server where the detection terminal is located; and if the geographic area where the IP address of the detection terminal is located is not provided with an area server, generating a third URL address of the resource to be detected according to the global unique identifier, wherein the third URL address is used for pointing to the resource pool, so that the resource pool receives a resource acquisition request which is sent by the detection terminal and carries the third URL address through the uniform access interface.

For example, a region where a region server is deployed, such as D city, E city, etc., may be stored. The geographic area where the IP address of the resource to be detected is released is city C, and the geographic area where the IP address of the detection terminal is located is city D. Then, the geographic area where the IP address of the issued resource to be detected is different from the geographic area where the IP address of the detection terminal is. At this time, it is determined that the geographic area where the IP address of the detection terminal is located is deployed with the area server, and then the second URL address is generated according to the global unique identifier.

For another example, the geographic area where the IP address of the resource to be detected is released is city C, and the geographic area where the IP address of the detection terminal is located is city F. Then, the geographic area where the IP address of the issued resource to be detected is different from the geographic area where the IP address of the detection terminal is. At this time, it is determined that the geographic area where the IP address of the detection terminal is located does not deploy the regional server, and then a third URL address, that is, an address of the resource pool, is generated according to the global unique identifier.

According to the method, the CDN and the regional server are deployed, so that the detection terminal can access the resource to be detected through the nearby CDN or the regional server, and the access speed of the resource to be detected is improved.

After the exemplary method for browsing the resource to be detected of the present disclosure is introduced, a method for downloading the resource to be detected is introduced next.

In specific implementation, a download request of the resource to be detected sent by a detection terminal is received, wherein the download request carries a globally unique identifier of the resource to be detected. And determining the fragment identifier corresponding to the global unique identifier carried in the downloading request according to the corresponding relation between the global unique identifier and the fragment identifier. And determining the fragmentation result of the resource to be detected corresponding to the acquired fragmentation identification according to the corresponding relation between the fragmentation result and the fragmentation identification. Synthesizing the obtained slicing results into complete resources to be detected according to a preset sequence; and returning the complete resource to be detected to the detection terminal.

In specific implementation, the preset sequence may be a time sequence, or may be a sequence of key values in the segment identifier. Specifically, the resources to be detected can be combined into complete resources according to the sequence of the key values in the fragment identifier.

For example, the download request carries the global unique identifier a 1234. And if the corresponding relation between the global unique identifier and the fragment identifier is that the global unique identifier A corresponds to the fragment identifiers A1, A2, A3 and A4, obtaining each fragment result of the resource to be detected, A1, A2, A3 and A4 according to the global unique identifier A1234, and synthesizing each fragment result into the complete resource to be detected according to the sequence of A1-A4.

According to the method, the resource to be detected does not need to be downloaded in a slicing mode when being downloaded, the resource to be detected can be synthesized into the complete resource to be detected and returned to the detection terminal, and the operation of the detection terminal can be reduced.
