    "sign_id": [123, 124...] //Signature ID, which can be specified with a value. For example, "sign_id":123
}

Note:
The "sig" field is generated according to the formula sha256(appkey=$appkey&random=$random&time=$time).
The pseudo codes are as follows:

string strAppkey = "5f03a35d00ee52a21327ab048186a2c4"; //The corresponding appkey of sdkappid, which must be kept confidential at the business side.
string strRand = "7226249334"; //The value of the "random" field in the URL
string strTime = "1457336869"; //UNIX timestamp
string sig = sha256(appkey=5f03a35d00ee52a21327ab048186a2c4&random=7226249334&time=1457336869)
