AFNetworking 的封装<一>

由于之前不太会用写文章,第一次写出来的东西不规整.现在重新整理一下.
对于AFNetworking的网络请求,大家应该都不陌生.经过实际的开发和自己的总结,现分享一套比价方便实用的封装请求.当然,每个项目的网络对接各异,这里也只是做出一个样例的展示,我们还是要根据自己项目的实际情况来封装AFN方法.
.h文件

#importtypedef NS_ENUM(NSUInteger,HttpRequestType) {
HttpRequestTypeGet = 0,//get
HttpRequestTypePost//post
};
@interface GlobelRequest : 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 (^)(NSDictionary * responseObject))success failure:(void (^)(NSError *error))failure;
/**
*  发送post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)postWithURLString:(NSString *)URLString parameters (id)parameters success:(void (^)(NSDictionary * responseObject))success failure:(void (^)(NSError *error))failure;
/**
*  发送网络请求---get/post 通用
*  @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 (^)(NSDictionary * responseObject))success failure:(void (^)(NSError * error))failure;

这里是AFNetworking的常用封装.关于图片上传的方法暂未涉及.往后会继续总结.篇幅不想写太长,第二个问题请见下一篇.
