iOS开发之网络请求(基于AFNetworking的再封装)

那现在就来说一下再封装的意义是什么？

最重要的意义差不多就是统一接口（这个也是封装的一个作用，如果不了解封装的同学可以去看看封装的用处，是个提高效率的非常有效的办法），这一点要是再多人项目中尤其能体现出来

那么我在网络请求的时候究竟最常用的网络请求有哪些呢？

我最常用到的就是get,post

上代码：

@interface UploadParam : NSObject
/**
*  图片的二进制数据
*/
@property (nonatomic, strong) NSData *data;
/**
*  服务器对应的参数名称
*/
@property (nonatomic, copy) NSString *name;
/**
*  文件的名称(上传到服务器后，服务器保存的文件名)
*/
@property (nonatomic, copy) NSString *filename;
/**
*  文件的MIME类型(image/png,image/jpg等)
*/
@property (nonatomic, copy) NSString *mimeType;
@end

@class UploadParam;

/**
*  网络请求类型
*/
typedef NS_ENUM(NSUInteger,HttpRequestType) {
/**
*  get请求
*/
HttpRequestTypeGet = 0,
/**
*  post请求
*/
HttpRequestTypePost
};

@interface HttpRequest : NSObject

/**
*  发送get请求
*
*  @param URLString  请求的网址字符串
*  @param parameters 请求的参数
*  @param success    请求成功的回调
*  @param failure    请求失败的回调
*/
+ (void)getWithURLString:(NSString *)URLString
parameters:(id)parameters
success:(void (^)(id responseObject))success
failure:(void (^)(NSError *error))failure;

/**

*
*  @param URLString  请求的网址字符串
*  @param parameters 请求的参数
*  @param success    请求成功的回调
*  @param failure    请求失败的回调
*/
+ (void)postWithURLString:(NSString *)URLString
parameters:(id)parameters
success:(void (^)(id responseObject))success
failure:(void (^)(NSError *error))failure;

/**
*  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 resultBlock 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;

/**

*
*  @param URLString   上传图片的网址字符串
*  @param parameters  上传图片的参数
*  @
