What this PR does:
To prevent reading the reader multiple times in #5201, instead we first parse the form to read the body if it is a POST request, then we set body to the buffer we copied. This could make sure we read the buf later only once.
I have added integration test cases for query frontend with vertical sharding enabled. Tests should pass after this fix.
Note:
If it is a GET request and it sets body to non empty, in this case the buffer is nil so we will set body to nil. But I think this is fine as
ParseForm
method only cares about url params and ignores body if it is a GET request.Which issue(s) this PR fixes:
Fixes #5201
