ios开发之--使用AFNetWorking 3.1.0 ，简单的请求封装类

从苹果系统自带的请求类，到ASIHttpRequest第三方请求类，再到AFNetWorking第三方请求类，目前只要牵扯到数据请求，基本上都是用AFN，所以，这里纯粹是记录下：

hRequestTools.h

#import <Foundation/Foundation.h>

/**
 *  网络请求类型
 */
typedef NS_ENUM(NSUInteger,HttpRequestType) {
    /**
     *  get请求
     */
    HttpRequestTypeGet = ,
    /**
     *  post请求
     */
    HttpRequestTypePost =
};

@interface hRequestTools : NSObject

/**
 *  发送网络请求
 *
 *  @param URLString   请求的网址字符串
 *  @param parameters  请求的参数
 *  @param type        请求的类型
 *  @param success     请求的结果
 */
+ (void)requestWithURLString:(NSString *)URLString
                  parameters:(id)parameters
                        type:(HttpRequestType)type
                     success:(void (^)(id responseObject))success
                     failure:(void (^)(NSError *error))failure;

hRequestTools.m

#pragma mark 封装的请求方法
+ (void)requestWithURLString:(NSString *)URLString
                  parameters:(id)parameters
                        type:(HttpRequestType)type
                     success:(void (^)(id responseObject))success
                     failure:(void (^)(NSError *error))failure
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    manager.requestSerializer.timeoutInterval = 30.0f;
    switch (type) {
        case HttpRequestTypeGet:
        {
            [manager GET:URLString parameters:parameters progress:^(NSProgress * _Nonnull downloadProgress) {
                
            } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                
                if (success) {
                    id jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers  error:nil];
                    success(jsons);
                }
                
            } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                if (failure) {
                    failure(error);
                }
            }];

        }
            break;
        case HttpRequestTypePost:
        {
            [manager POST:URLString parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
                
            } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                
                if (success) {
                    id jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers  error:nil];
                    success(jsons);
                }
                
            } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                
                if (failure) {
                    failure(error);
                }
                
            }];
        }
            break;
        default:
            break;
    }

}

请求里面如果要加缓存的话，可以和YYCache这个第三方配合使用，
