Information synchronization between your server and Tencent Cloud's CVM can be implemented by combining the following two ways:
You can call relevant API using GET request method of HTTP protocol on your server, that is, the parameters in the call are directly added in the URL. Example on how to call the API is provided in every API's documentation, so there is no difficulty in interfacing.
To ensure performance, we use HTTP protocol to call the API. Therefore, an effective measure is required to ensure the communication security between your server and Tencent Cloud backend.
All LVB Code-related cloud APIs employ the same security check mechanism - "t + sign verification":
Assume that the key is 5d41402abc4b2a76b9719d911017c592, and after calculation we can get the following signature:
t = "2016-08-22 15:17:27" = 1471850187
sign = MD5(5d41402abc4b2a76b9719d911017c5921471850187) = b17971b51ba0fe5916ddcd96692e9fb3
