Question

I am working on one project in which I am preparing API to interact with server from iPhone.

I have created API with POST parameter xmlrequest and in that parameter, I am passing xml content.

Everything is working correctly, except, when in xml content if any special character comes, it cuts off on server side.

My question is should I apply any header/content type on both sides, if yes, Can I get example ?

EDIT:

It is an issue of special character, in xml content I tried to replace “&” with “and” and it worked, but when I try to replace “&” with “&”, it does not work.

In HTTP, GET- and POST- parameters are seperated with the special characters ?, & and =. I’m sure you already have seen things like that in URLS: example.com?foo=bar&meow=woof

Your server will parse the query-string, and it assumes that everytime a & appears, it’s a new parameter. So, in order to pass such a special character, you first need to URL-encode it (on the iPhone-side). For example, the space-character, URL-encoded, would be %20.

You can then decode the URL-encoded string on server side using urldecode() and rawurldecode().
