Re: [libmicrohttpd] Can handle Content-Type = application/json ?

[Justin Graves]

We are running libmicrohttpd in an API which uses JSON in both request and response bodies almost exclusively with no issue. We do also use form data. If the client sends a body with "application/json" as the "Content-Type" header, we will see whatever they sent via MHD_get_connection_values.

I have just verified this, using libmicrohttp v0.9.62, by sending a request with a "Content-Type" header of "application/json", then using MHD_get_connection_values with MHD_HEADER_KIND, and it gives me a key of "Content-Type" exactly once with a value of "application/json".

Perhaps providing example code related to your header parsing would help?

Gentlepeople:

 

I am using libmicrohttpd to make, naturally, a web server.  The client wants to send me a post request with a content type of “application/json”.

 

Libmicrohttpd doesn’t seem to support application/json.  Only "application/x-www-form-urlencoded" and "multipart/form-data".  I tried using MHD_set_connection_value as the source code suggested, but it doesn’t work.  I suspect it doesn’t replace the existing Content-Type key, but adds a header to the end.

 

Does libmicrohttpd just not work for this case?  I don’t feel I can tell my client not to send me application/json.  It’s such an obvious and commonly accepted format.

 

Ideas?
