is there an example of AFHTTPClient posting json with AFNetworking?

Question

Looking for an example of how to post json with AFHTTPClient. I see that there is a postPath method which takes an NSDictionary and the AFJSONEncode me

Answer 1

The best and simple way to do that is to subclass AFHTTPClient.

Use this code snippet

MBHTTPClient

#define YOUR_BASE_PATH @"http://sample.com"
#define YOUR_URL @"post.json"
#define ERROR_DOMAIN @"com.sample.url.error"

/**************************************************************************************************/
#pragma mark - Life and Birth

+ (id)sharedHTTPClient
{
    static dispatch_once_t pred = 0;
    __strong static id __httpClient = nil;
    dispatch_once(&pred, ^{
        __httpClient = [[self alloc] initWithBaseURL:[NSURL URLWithString:YOUR_BASE_PATH]];
        [__httpClient setParameterEncoding:AFJSONParameterEncoding];
        [__httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
        //[__httpClient setAuthorizationHeaderWithUsername:@"" password:@""];
    });
    return __httpClient;
}

/**************************************************************************************************/
#pragma mark - Custom requests

- (void) post<#Objects#>:(NSArray*)objects
success:(void (^)(AFHTTPRequestOperation *request, NSArray *objects))success
failure:(void (^)(AFHTTPRequestOperation *request, NSError *error))failure
{
    [self postPath:YOUR_URL
       parameters:objects
          success:^(AFHTTPRequestOperation *request, id JSON){
              NSLog(@"getPath request: %@", request.request.URL);

              if(JSON && [JSON isKindOfClass:[NSArray class]])
              {
                  if(success) {
                      success(request,objects);
                  }
              }
              else {
                  NSError *error = [NSError errorWithDomain:ERROR_DOMAIN code:1 userInfo:nil];
                  if(failure) {
                      failure(request,error);
                  }
              }
          }
          failure:failure];
}

Then in your code just call

[[MBHTTPClient sharedHTTPClient]  post<#Objects#>:objects
                                          success:^(AFHTTPRequestOperation *request, NSArray *objects) {
    NSLog("OK");
}
                                          failure:(AFHTTPRequestOperation *request, NSError *error){
    NSLog("NOK %@",error);
}

objects is an NSArray (you can change it to NSDictonary) and will be encode in JSON format
