Sending a JSON object to a web app function via Http?

[valheru]

Hi,

I'm not sure if this question even makes sense, so bear with me here.

I'm using a tool called HtmlUnit (which is like JUnit) to send a http
request to my web application. The http address needs to include JSON
objects because the JavaScript/Java functions at the web application
are expecting to receive them as parameters.

Let me clarify:

suppose the web app servlet has a (Java) function:

boolean myfunction(JSON Object myobject)

and I want to call it from an outside test using Html, how do I do
this?

I want to send a request like "http://localhost/json/<path>/
myfunction" and then put the JSON object stuff at the end of the http
line so that the function myfunction accepts it as the parameter
myobject.

How do I do this? Can it be done? Is this "the way" to send such
objects to such functions?

Thanks for your help. Any info would be appreciated.

Irrelevant. Java is not JavaScript.

You would need to encode the path component so that the URI complies
with RFC 3986, and a server that supports either the PATHINFO feature (with
which foo/<encoded-jsonwould be possible) or append the encoded as the
query part after the `?' character (foo?[name=]<encoded-json>).

In ECMAScript implementations this can be achieved by using the return value
of the encodeURICompon ent() method, and that of escape() as a fallback.

Can it be done?

Yes.

Is this "the way" to send such objects to such functions?

The usual approach is to use a POST request instead, for the URI length is
not limited per default, but it is in Internet Explorer, to 2083 characters.

Thanks for your help. Any info would be appreciated.
