I'm using fastcgi++ for my ajax pages, parsing and encoding with json-spirit. (I'm also very new to c++)
I'm having trouble figuring out how to access the post data.
I cut my teeth on .net & php, and those would conveniently convert a json data string (speaking in jQuery here, so my vocab is probably off) to simple variables or $_POST
array respectively.
I'm looking at the main example for reading POST data on fastcgi++ http://www.nongnu.org/fastcgipp/doc/2.1/a00003.html, but it only shows it->first
and it->second.value
. I can't find anything in the linked docs on that page.
Since I don't have the http knowledge to articulate this properly, is there a way to read a jQuery ajax()
data
string, for example, {foo: "bar", jim: "bob"}
by foo
and jim
in fastcgi++?
If not, should the it->first
simply be treated as a string to be parsed by json-spirit ?
Ah, OK.
First, jQuery http://api.jquery.com/jQuery.ajax/
data
Type: PlainObject or String
Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests.
So jQuery does break it up into a POST query string for you.
Then, fastcgi++, via the Session tutorial, there's a piece of code environment().findPost("data").value
that apparently references the element <input type='text' name='data' value='Hola señor, usted me almacenó en una sesión' />
. No need to use spirit to parse incoming ajax data.
environment()
looks like it's initialized automatically for you in Fastcgipp::Request
.
I'm loving this framework more each day!
Now, I just need to figure out how to integrate it with websocket++...
How a multi-level json object will be converted into a query string and read in via fastcgi++ is probably best left to another question.
