ProtocolViolationException: Cannot send a content-body with this verb-type
Issue Description
.NET runtime gives below error,
The above error is most visible in the Client application which tries to send HTTP requests like GET or DELETE request with Body parameter.
Resolution
I found such errors are as per the design following a few RFC specifications clarifying the same.
.NET Framework doesn’t support body in GET and DELETE
Currently, regular .NET Framework doesn’t support GET or DELETE method with request body as we learned in the guidelines
But as per RFC 7231 specification clarifies the support for GET method with body parameters. But also warns us of its usage.
These specifications however not yet implemented in the regular .NET framework but supported in .NET Core framework
RFC Specification
As per RFC 7231
GET is the primary mechanism of information retrieval and the focus of almost all performance optimizations.
A payload within a GET request message has no defined semantics; sending a payload body on a GET request might cause some existing implementations to reject the request.
Similar specifications also exist for HTTP DELETE method also.
Support in .NET Core – Available
.NET Core seems already supporting the above specification and allow us to send Body parameter([FromBody] within HTTP GET and DELETE method,
Please see the example here
It seems it’s not easy to provide a straight resolution for such an issue but the above guidelines can help us to know any limitations, challenges, etc.
Did I miss anything else in these resolution steps?
Did the above guidelines help to assist in resolving the issue?
