对AFNetworking进行简单的封装

如题利用单例模式对AFNetworking进行简单的封装(仅仅是封装了最基本的GET，POST请求)。供新手使用。
首先你得先装好

.h文件中AFNetworking框架......这个就不用多说了吧......

#import <AFNetworking/AFNetworking.h>
//成功时的回调
typedef void(^successBlock)(id responseObjects);
//失败时的回调
typedef void(^failureBlock)(NSError *error);

@interface HBQNetWorkTools : AFHTTPSessionManager

//单例模式
+ (instancetype)SharedManager;

//Get请求方式
- (void)get_RequestWithUrl:(NSString *)urlString 
                parameters:(NSDictionary *)parameters 
              successBlock:(successBlock)success 
              failureBlock:(failureBlock)failure;

//post请求方式
- (void)post_RequestWithUrl:(NSString *)urlString 
                 parameters:(NSDictionary *)parameters 
               successBlock:(successBlock)success 
               failureBlock:(failureBlock)failure;

@end

.m文件中
#import "HBQNetWorkTools.h"

@implementation HBQNetWorkTools

#pragma mark - 单例模式
+ (instancetype)SharedManager {
      static HBQNetWorkTools *instance;

      static dispatch_once_t onceToken;
      dispatch_once(&onceToken, ^{
    
      NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    
      instance = [[HBQNetWorkTools alloc] initWithSessionConfiguration:configuration];
    
      //设置请求格式(默认格式为二进制格式)
      instance.requestSerializer = [AFJSONRequestSerializer serializer];
      //设置可接受的响应格式
      instance.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
       //设置请求超时时间(默认10s)
        instance.requestSerializer.timeoutInterval = 10.0;
    
    });

   return instance;
}

#pragma mark - get网络请求
- (void)get_RequestWithUrl:(NSString *)urlString parameters:(NSDictionary *)parameters successBlock:(successBlock)success failureBlock:(failureBlock)failure {

    [[HBQNetWorkTools SharedManager] GET:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    
        success(responseObject);
    
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    
        failure(error);
    }];
}
#pragma mark - post网络请求
- (void)post_RequestWithUrl:(NSString *)urlString parameters:(NSDictionary *)parameters successBlock:(successBlock)success failureBlock:(failureBlock)failure {

    [[HBQNetWorkTools SharedManager]POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    
        success(responseObject);
    
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        failure (error);
   }];
}
