Hi All
I need to write an application that receive a POST with simple Json
{"variable1":"Value","Variable2":"Value",....}

I'm using synapse library (but I can change and use another library)
but i didn't see any example....

I do not know about synapse, but if  you use fpweb, TRequest has
OnUnknownEncoding event which will be called when request is handling
POST or PUT request but with unknown content type.

Currently fpweb TRequest handles multipart/form-data and
application/x-www-form-urlencoded only. So POST with application/json
content-type is unknown content type.

However to be able to set OnUnknownEncoding event you need to set it
before request body is read and parsed.
Best place to set it I guess would be to override
TFPCustomHttpServer.initRequest() method. This method is called after
TRequest instance is created but before reading data from socket.

Indy has a TIdHTTPServer  component.  In its OnCommandGet event (which
also handles POSTs), you can access the JSON data via the provided
ARequestInfo parameter, in its PostStream property.
