Request Body

Last updated: 2020-06-07 19:06:31


    This is a legacy API which has been hidden and will no longer be updated. We recommend using the new LVB API 3.0 which is standardized and faster.

    1. Service Address

    The domain name for the Tencent Cloud LVB service is

    2. Communication Protocol

    All the Tencent Cloud APIs communicate over HTTPS to provide high-security channels.

    3. Request Methods

    POST and GET requests are both supported, but cannot be used at the same time. If the GET method is used, the parameters are obtained from Querystring. If the POST method is used, the parameters are obtained from Request Body, and the parameters in the Querystring are ignored. The request parameters are organized in the same way in both types of requests. Generally, GET method is used. If the parameter strings are too long, POST method is used. For more information, please see the relevant API description.

    4 Character Encoding

    UTF-8 encoding is always used.
