Question

I wrote two code both are same

1. Using NSURLConnection and
2. Using AFNetworking.

My NSURLConnection code works fine but AFNetworking code don’t. Problem is I am getting JSON response from my NSURLConnection code but I am not getting JSON response from AFNetworking code but I am getting response code as 200. . I have tried all possible combination but still no luck. I dont know what is the problem. I wnat to use AFNetworking going forward so please someone help me. Thank you, — Amit

NSURLConnection:

- (IBAction)connectHandler:(UIButton *)sender {

//This is where we attempt to connect to the URL represented by self.labelHostURL
//along with exception handling
NSString *request_type = @"STARTUP";    
NSString *request_data = @"{\"lstCacheRefDt\":\"10/10/2010\",\"langCd\":\"en_US\",\"timeZn\":\"America/Chicago\",\"brndId\":\"WM\",\"prgmId\":\"WM0012\"}";
NSLog(@"Request: %@", request_data);

NSURL *url = [NSURL URLWithString:[ self.labelHostURL text ]];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
//NSData *requestData = [NSData dataWithBytes:[request_data UTF8String] length:[jsonRequest length]];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

NSString* request_body = [NSString
                          stringWithFormat:@"request_type=%@&request_data=%@",
                          [request_type stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
                          [request_data stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

[request setHTTPBody:[request_body dataUsingEncoding:NSUTF8StringEncoding]];

[NSURLConnection connectionWithRequest:request delegate:self];    }

AFNetworking:

- (void) getHomeData {

NSURL *url = [[NSURL alloc] initWithString:@"https://localhost:8443/MNMMLMockService/mAccountsWeb/services/mnapp/rpc"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];

NSDictionary *homePostParams1 = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"10/10/2010", @"lstCacheRefDt",
                                @"en_US", @"langCd",
                                @"America/Chicago", @"timeZn",
                                @"WM", @"brndId",
                                @"WM0012", @"prgmId", nil];

NSDictionary *homePostParams = [NSDictionary dictionaryWithObjectsAndKeys:@"STARTUP", @"request_type", homePostParams1,@"request_data", nil];

NSLog(@"Dic: %@", homePostParams);

NSMutableURLRequest *homeRequest = [httpClient requestWithMethod:@"POST" path:@"" parameters:homePostParams];
[homeRequest setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[homeRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:homeRequest
                                     success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
                                         NSLog(@"JSON %@", JSON);
                                         NSLog(@"operation StatusCode: %d", [response statusCode]);
                                     } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
                                         NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
                                     }];
[operation start]; }

Answer 1

I use AFNetworking library but you seem to be missing some steps that I do. I usually subclass AFHTTPClient. Whether you subclass or not, make sure to call AFHTTPClient’s registerHTTPOperationClass method.

For example in my AFHTTPClient subclass during the init process, I do (where self is AFHTTPClient instance) :

[self registerHTTPOperationClass:[AFJSONRequestOperation class]];

This will set the appropriate accept headers for you.

For operations (all expect json responses), I do something like:

AFHTTPRequestOperation *httpOperation = [httpClient HTTPRequestOperationWithRequest:request 
    success:^(AFHTTPRequestOperation *operation, id responseJSONObject) { // some logic}
    failure:^(AFHTTPRequestOperation *operation, NSError *error) { // some logic }];
