POST request in method-based service

Hi
How to easy process POST request in method-based service, i.e.:
- how to extract parameters from JSON payload?
- request Content type: text/plain or application/json?
- is it possible to use GetInputAsTDocVariant?

Regards, Tomek

Re: POST request in method-based service

Did you read the documentation about method-based services?

Did you check the corresponding samples?

Yes, I read:
https://synopse.info/files/html/Synopse … ml#TITL_49
http://blog.synopse.info/post/2010/07/1 … phi-7-2010
and unless I missed something, all of it with corresponding samples are related with GET request and extracting parameters from URI.

Check the https://synopse.info/files/html/api-1.1 … URICONTEXT documentation.

For the JSON body, you can use either JsonDecode(), or a TDocVariantData.

Re: POST request in method-based service

procedure TRemoteSrv.Test(Ctxt: TSQLRestServerURIContext);
var
 vBody: RawJSON;
 res: array [0..0] of TValuePUTF8Char;
 sParam: RawUTF8;
begin
  if Ctxt.Method = mPOST then begin
    vBody := Ctxt.Call.InBody;
    JSONDecode(vBody, ['Param1'], @res, true);
    sParam := res[0].Value;
  end;
  Ctxt.Results(['Test: ' + sParam]);
end;

This is what you meant?

Yes!

And make sure your code is thread-safe, because method-based service execution runs in parallel.
