1. Timestamp Problem: The interface signature generation of Tik Tok needs a timestamp, which is usually the number of milliseconds of the current time. If your time format is incorrect, signature verification will fail. It is recommended that you use the tool class library to generate timestamps in the correct format.
2. Parameter problem: most interfaces of Tik Tok need to pass some parameters, and the number and types of these parameters must be consistent with those specified in the interfaces, otherwise the signature verification will fail. Please check whether the number, types and values of your parameters are correct, and set them according to the requirements of official documents.
3. Encryption: The interface signature of Tik Tok is generated by encryption using a specific algorithm. If your encryption process is incorrect, the signature cannot be verified. Please use the correct encryption algorithm to calculate the signature according to the official document requirements.
4. Version number problem: If you use Tik Tok's API, you may need to include the API version number in the request. If you use an expired version number, the signature will not be verified. Please check your request parameters to ensure that you are using the correct API version number.
If you have checked the above problems, but still can't generate the interface signature, please check the interface documentation of Tik Tok to see if there are any special requirements or precautions. If the problem still exists, you can try to contact Tik Tok's technical support personnel and provide detailed error information and logs to quickly locate the problem.
