NSString *postUrl = @"http://www.huway.com/api_index?module=event&action=topads";

NSDictionary *parameters = @{@"PARAMETERS NAME 1" : @"PARAMETERS VALUE 1",
@"PARAMETERS NAME 2" : @"PARAMETERS VALUE 2"};

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

//方法一：
//    manager.requestSerializer = [AFJSONRequestSerializer serializer];
//    manager.responseSerializer = [AFJSONResponseSerializer serializer];
//    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
//    [manager.requestSerializer setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

//注意：默认的Response为json数据
//    [manager setResponseSerializer:[AFXMLParserResponseSerializer new]];
//    manager.responseSerializer = [AFHTTPResponseSerializer serializer];//使用这个将得到的是NSData
manager.responseSerializer = [AFJSONResponseSerializer serializer];//使用这个将得到的是JSON

//注意：此行不加也可以
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/plain", @"text/html", nil];
//    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
//    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain; charset=utf-8"];
//    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/plain"];

//SEND YOUR REQUEST
[manager POST:postUrl parameters:NULL success:^(AFHTTPRequestOperation *operation, id responseObject) {
