创建 Playsafe Token

接口URL

https://hls.videocc.net/service/v1/token

接口说明

1. 用于创建 Playsafe Token，这个 token 即是加密视频的播放凭证
2. 如果一个token尚未过期，此时使用相同的 videoId、viewerId、viewerIp、iswxa 参数值请求该接口，则会复用原来的token，并延长原token的有效期。

响应失败JSON示例：

userId 错误

{
    "code": 400,
    "status": "error",
    "message": "user_not_found",
    "data": "user secretKey not found."
}

ts 过期

{
    "code": 403,
    "status": "error",
    "message": "ts_expired",
    "data": "ts parameter is expired."
}

签名错误

{
    "code": 403,
    "status": "error",
    "message": "sign_invalid",
    "data": "sign parameter invalid."
}

响应字段说明

签名规则

1. 将除了 sign 之外的全部 非空 请求参数（也就是说，参数值为空的参数，将排除掉，不参与签名的计算），按字典序升序排列，按“参数名1参数值1参数名2参数值2……”的格式拼接起来，例如：ts1552447784505userIde6b23c6f51videoIde6b23c6f51c4b1cb9f0302a92ed42440_eviewerIdabcd1234viewerIp127.0.0.1
2. 在上述字符串的头、尾分别加上 secretKey。以上述字符串、secretKey为abc为例，得到：abcts1552447784505userIde6b23c6f51videoIde6b23c6f51c4b1cb9f0302a92ed42440_eviewerIdabcd1234viewerIp127.0.0.1abc
3. 计算上述字符串的MD5值，并转为大写，得到：166D45560D37DDBF0F05081D975231B5
