AFNetworking 如何POST一個JSON數據到服務器

  NSString *pathStr=@"http://www.baidu.com" ;

                                AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@""]];//這裏要將url設置爲空

                                httpClient.parameterEncoding = AFJSONParameterEncoding;

                                [httpClient setDefaultHeader:@"Accept" value:@"text/json"];

                               
                                NSMutableDictionary *params=[[NSMutableDictionary alloc] init];   // 要傳遞的json數據是一個字典

                                [params setObject:UserID forKey:@"userId"];

                                [params setObject:[self.contDic objectForKey:@"weiboId" ] forKey:@"operateId"];

                                [params setObject:@"8d0ce196d0eafa27780cc3a7217de71d92474021dc0a4fc593d4f9b9eda320ca" forKey:@"key"];

 

                                 // httpClient 的postPath就是上文中的pathStr，即你要訪問的URL地址，這裏是向服務器提交一個數據請求，

                                [httpClient postPath:pathStr parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

                                    NSLog(@"data====%@",params);

                                    NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];

                                    NSLog(@"Request Successful, response '%@'", responseStr);

                                    [responseStr release];

                                } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

                                    NSLog(@"[HTTPClient Error]: %@", error);
