c# - Cannot send a content-body with this verb-type with GET request -

-

i'm receiving request through webapi, , trying resend site.

the goal receive request, example: http://localhost:9999/#q=test. , forward real site:(for test set google.com) http://google.com/#q=test

i've following code:

    protected override async task<httpresponsemessage> sendasync(httprequestmessage request, system.threading.cancellationtoken cancellationtoken)     {         string url = request.requesturi.pathandquery;         uribuilder forwarduri = new uribuilder(_otherwebsitebase);         forwarduri.path = url;         if (request.method == httpmethod.get)         {             //request.method = httpmethod.post;         }         request.requesturi = forwarduri.uri;         request.headers.host = forwarduri.host;         return await _client.sendasync(request, httpcompletionoption.responseheadersread);//_client httpclient     }

currently got system.net.protocolviolationexception states: cannot send content-body verb-type.

but input request request(and should request). if put post request, don't have exception anymore, google says don't expect post request.

so why exception coming? idea on how fix it?

i ended creating copy of initial request, , sending again:

protected override async task<httpresponsemessage> sendasync(httprequestmessage request, system.threading.cancellationtoken cancellationtoken) {     string url = request.requesturi.pathandquery;     uribuilder forwarduri = new uribuilder(_otherwebsitebase);     forwarduri.path = url;      httprequestmessage newrequest = request.clone(forwarduri.uri.tostring());      httpresponsemessage responsemessage = await _client.sendasync(newrequest);     return responsemessage; }

the clone method following, inspired question: how forward httprequestmessage server

    public static httprequestmessage clone(this httprequestmessage req, string newuri)     {         httprequestmessage clone = new httprequestmessage(req.method, newuri);          if (req.method != httpmethod.get)         {             clone.content = req.content;         }         clone.version = req.version;          foreach (keyvaluepair<string, object> prop in req.properties)         {             clone.properties.add(prop);         }          foreach (keyvaluepair<string, ienumerable<string>> header in req.headers)         {             clone.headers.tryaddwithoutvalidation(header.key, header.value);         }         clone.headers.host = new uri(newuri).authority;         return clone;     }
