iOS上的Http请求

Question

So i am trying to make an http request using ASIHTTPRequest class , to send a json file to my server. I was given an android code which is functional and was asked to convert it to iOS code. I cant understand how to add headers on my request.The android code looks something like this :

private static final String CONTENT_TYPE = "Content-Type";
private static final String JSON_CONTENT_TYPE = "application/json; charset=utf-8";

and then :

request.addHeader(CONTENT_TYPE, JSON_CONTENT_TYPE);

On iOS i figured out that the code is something like this :

[request addRequestHeader:@"Content-Type" value:@"Content-Type"];
[request addRequestHeader:@"Json-Content-Type" value:@"application/json; charset=utf-8"];

BUT i got a bit confused , cause on android the request seems to be paired and on iOS the requestHeaders are individually stated. Is this a problem? Should they be paired too on iOS. Am i missing something here? Thank you for reading my post :D

Answer 1

What you want is

[request addRequestHeader:@"Content-Type" value:@"application/json; charset=utf-8"];

in the android example, they are just declaring two variables for the header values, they could had simply done something like

request.addHeader("Content-Type", "application/json; charset=utf-8");

which would have had the same effect, so you just need the one line i mentioned above.

also: ASIHTTPREQUEST does not get developed any more (see headline here) , so consider using another library for something like this, like AFNetworking
