IOS - Same ASIHTTPRequest code doesn't work only one method - ios

Question

In my project I make the other functions work with this code. But for this method I cannot make it work. I did copy-paste all this code for different methods(changing URL ,Result). The parameters of this methods are only int and string.
I always correct the wcf method from SOAP UI and .NET project.It works correct.
I only cannot make this code work for this method.
The [request responseString] returns a patient's information. Please help me. Thank you.
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:HASTAARAIP]];
NSData *myPostData = [[NSString stringWithFormat:#"{\"kat\":0,\"oda\":0,\"hastaAdi\":\"KAI\",\"protokolNo\":0,\"yatanAyaktan\":1}"] dataUsingEncoding:NSUTF8StringEncoding];
NSMutableData *myMutablePostData = [[NSMutableData alloc]initWithData:myPostData];
[request setPostBody:myMutablePostData];
[request setRequestMethod:#"GET"];
[request addRequestHeader:#"Content-Type" value:#"application/json"];
[request setDelegate:self];
[request startSynchronous];
Here is some things that can make you understand.
With this code the [request responseString] and [request responseStatusMessage] is null. But if I remove the line where the addRequestHeader, it says for responseStatusMessage HTML/1.1HTTP/1.1 404 Not Found 404. I didn't understand why it gives this 404 error. This request type works for the other methods.
The ıp is like http://.../rest/<methodname>
Added log for a part of responsestring`:
The server encountered an error processing the request. The exception
message is 'The incoming message has an unexpected message format
'Raw'. The expected message formats for the operation are 'Xml';
'Json'. This can be because a WebContentTypeMapper has not been
configured on the binding. See the documentation of
WebContentTypeMapper for more details.'. See server logs for more
details. The exception stack trace is:
Updated:
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:HASTAARAIP]];
[request setPostValue:#"0" forKey:#"kat"];
[request setPostValue:#"0" forKey:#"oda"];
[request setPostValue:#"KAI" forKey:#"hastaAdi"];
[request setPostValue:#"0" forKey:#"protokolNo"];
[request setPostValue:#"1" forKey:#"yatanAyaktan"];
[request startSynchronous];
But for responseString the logs:

The expected message formats for the operation are 'Xml'; 'Json'. This can be because a WebContentTypeMapper has not been configured on the binding.

Trying with AFNetworking:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"kat": #"0",#"oda": #"0", #"hastaAdi":hastaAdi, #"protokolNo":#"0",#"yatanAyaktan":#"1"};
[manager.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[manager POST:HASTAARAIP parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
But the log is like this:
Error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x8e49ce0 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}

ASI was long abandoned by the developer. using AFNetworking 2.0 will be more easy, and with a lot of good documentation: https://github.com/AFNetworking/AFNetworking
it looks like you are trying to make a #"POST" request.
you can use the following code snippet (uses IOS build in classes) to make the request:
NSDictionary *parameters = #{#"key" : value};
/* the following serialization is NOT a deep serialization */
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:nil];
NSURL *url = [NSURL URLWithString:#"http://www.someURL.com/whatEver"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20.0f];
[request setHTTPMethod:#"POST"];
[request addValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:jsonData];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if ([response isKindOfClass:[NSHTTPURLResponse class]]) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
NSLog(#"all headers from response:%#", [httpResponse allHeaderFields]);
NSLog(#"status code from response:%ld", (long)[httpResponse statusCode]);
}
}];
