Synchronization moderation interface

Request specification

• Request URL:

Get it from the Console - Service Configuration

• Interface description:

Submit the video information to the interface. After the information is submitted, screenshots of the video will be detected, and the results need to be obtained by calling the Result Obtaining Interface.

• Supported Formats:

1.Audio package formats supported by the detection interface：wav、mp3、aac、amr、3gp、m4a、wma、ogg、ape etc

2.Audio duration needs to be less than 1 minute

• HTTP Request Header:

• Request method：POST

• Request body JSON object:

• Example of request body:

  JSON Response
  
      {
      "type":1,
      "lang":"zh-CN",
      "audio":"http://xxx.xxx.com/xxxx",
      "userId": "testUser"
      }  
  

• Request signature:

When the user requests the Video Submit API, the request can be signed with the appId and secretKey (obtained from the Console - Service Configuration). When the API receives the request with the signature information, it will verify the signature using the same algorithm, and if the signature is found to be inconsistent, the API will return 401 error to the user.

If the API validates the signature to be consistent and the user corresponding to the appId has permission to operate the requested resource, then the request succeeds, otherwise the API returns 401 error.

• Send signatures by HTTP Request Headers

Method: Add a header named Authorization in the request, whose value is the signature value. For example:

 Authorization: Njl86M/jY6zZaZoGhZdGO+GI/8+yGFECusGH1yQHUFE=

• Signature calculation method

1. Canonicalized Query String:

Convert the request body JSON string to a hexadecimal string (not Base64) by doing sha256 encoding with UTF-8 character encoding.

CanonicalizedQueryString = hex(sha256(jsonBody))

2. Constructs the signed string StringToSign ("\n" stands for ASCII newline character):

   StringToSign = HTTPMethod + “\n” + HostHeaderInLowercase + “\n” + HTTPRequestURI + “\n” + CanonicalizedQueryString <obtained from previous step

               > + "\n" +
               "X-AppId:" + SAME_APPID_IN_HEADER + "\n" +
               "X-TimeStamp:" + SAME_TIMESTAMP_IN_HEADER
   

HTTPRequestURI is the absolute path to the request URI, not containing the CanonicalizedQueryString. If the HTTPRequestURI is empty, a forward slash (/) will be retained.

The hash-based message authentication code (HMAC) is created using the HMAC-SHA256 protocol and then the signature is calculated.

3. StringToSign serves as the signature string, secretKey serves as the secret key and SHA256 serves as the hash algorithm.

   For more information about HMAC, see: https://tools.ietf.org/html/rfc2104。
   

4. Converting the results of the previous step to a BASE64 string

5. Put the BASE64 string into the Authorization of HTTP request Header

• Example of signature

Below is an example of appId & secretKey & audio

appId=1000
secrectKey=d9e23d93053f49ade2f8fce185acedd4
audio_url="http://xxx.xxx.com/xxxx"

Below is an example of request body.

{
 "type": 1,
 "audio":"http://xxx.xxx.com/xxxx",
 "userId": "12345678"
}
