AFNetWorking实现参数以body传输请求数据

/**
 *  异步POST请求:以body方式,支持数组
 *
 *  @param url     请求的url
 *  @param body    body数据
 *  @param success 成功回调
 *  @param failure 失败回调
 */
+ (void)postWithUrl:(NSString *)url body:(NSData *)body success:(HttpSuccess)success failure:(HttpSuccess)failure {

    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:url parameters:nil error:nil];
    request.timeoutInterval = TIMEOUTINTERVAL;
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    // 设置body
    [request setHTTPBody:body];

    AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",@"text/json", @"text/plain", @"text/html", nil];
    [[manager dataTaskWithRequest:request completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
        if (error) {
            failure(error);
        } else {
            id json = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil];
            success(json);
        }
    }] resume];
}
