Question

I have a problem with json.
I have to do query:

{
"method": "authorize",
"params": [
"100000202",
"TestApp677"
]
}

To endpoint:http://xzasddfe.com/authorize/?ver=2_01

How to do it?

Answer 1

First take a look at some JSON libraries. I prefer JSONKit , as it`s really easy to use.

Next select a method to post data to your endpoint ( NSURLConnection , ASIHTTPRequest).

Here is an example using JSONKit and NSURLConnection:

-(void) postData {
   NSURL *url=[NSURL URLWithString:@"http://xzasddfe.com/authorize/?ver=2_01"];

    NSMutableDictionary *dic=[NSMutableDictionary dictionary];
    [dic setValue:@"authorize" forKey:@"method"];
    [dic setVObject:[NSArray arrayWithObjects:@"100000202",@"TestApp677",nil] forKey:@"params"];

    NSString *jsonString=[dic JSONString];

    NSMutableURLRequest *request=[[NSMutableURLRequest alloc] initWithURL:url];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];

    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    [request release];

}
