Due to the differences in required common parameters between different API styles, the request syntax and signature method V2 vary based on the API style.
If you want to use the request syntax and signature method V2 to construct HTTP requests, see the following topics based on the API style of the cloud service that you want to access:
Request syntax and signature method V2 for ROA APIs
Request syntax and signature method V2 for RPC APIs
The request syntax and signature method V2 are discontinued. We recommend that you use the request syntax and signature method V3.
Note
APIs that support the signature method V2 also support the signature method V3.
