Verify Signature Result

Last Updated on : 2022-11-01 09:37:35download

To improve service security, Tuya has updated the signature algorithm. This topic describes how to view the input parameters and decryption result of sign by using Postman. You can verify the encryption result of sign in the cloud API requests.

Prerequisites

Procedure

The API package provides scripts for calculating sign. You can use Postman’s console to print log parameters for verification.

  1. Add code to print console.log.
    In Postman, log in to the Pre-request Script page and find function calcSign. In the function, add the following code lines:

    // `str` is the input parameter of encryption
    console.log("str:",str);
    // `sign` indicates the encryption result
    console.log("sign:",signUp)
    

    Note: The verification calculation parameters of token requests (the APIs to get and refresh a token) are different from that of business requests (APIs other than the token management APIs). Select the correct API request calculation rule.

    Verify Signature Result

  2. Log in to the Console.

    Verify Signature Result

  3. Call APIs and view the returned result.
