iOS 纯原生 网络请求 简单封装

问题原因

项目里有用到网络请求，但因为请求相对简单，就没使用现成的什么三方SDK了，就只是将iOS自带的网络请求封装了下。
因为各个项目用到的数据结构和功能可能不一样，所以这里尽可能多的兼容了多种情况，各位可以按需取用。

实现

NetWorkManager.h

#import <Foundation/Foundation.h>

//请求类型枚举
typedef NS_ENUM(NSInteger,NetWorkHTTPMethod) {
    
    
    NetWorkHTTPMethod_GET,//请求指定页面信息，并返回实体主体
    NetWorkHTTPMethod_POST,//向指定的资源提交数据进行处理请求（例如提交表单或上传文件），
    //数据被包含在请求体中。post请求可能会导致新的资源的建立或已有资源的修改
    NetWorkHTTPMethod_HEAD,//类似隔天请求，只不过返回的响应中没有具体的内容，用于获取报头
    NetWorkHTTPMethod_OPTIONS,//允许客户端查看服务器的性能
    NetWorkHTTPMethod_PUT,//从客户端向服务器传送的数据取代指定的文档内容。
    NetWorkHTTPMethod_DELETE,//请求服务器删除指定的页面
    NetWorkHTTPMethod_TRACE,//回显服务器收到的请求，主要用于测试或诊断
    NetWorkHTTPMethod_CONNECT,//http/1.1协议中，预留给能够将连接改为管道方式的代理服务器
};

//通讯类型枚举
typedef NS_ENUM(NSInteger,NetWorkContentType) {
    
    
    NetWorkContentType_JSON,//application/json
    NetWorkContentType_PROTOBUF,//application/x-protobuf
    NetWorkContentType_PNGIMAGE,//image/png
    NetWorkContentType_VIDEOMP4,//video/mpeg4
    NetWorkContentType_JPGIMAGE,//image/jpeg
};

备注

上面很多方法和枚举的定义，是为了外部调用更简洁，可以适当自己增加自己需要的。
这个封装里面，没有进行多请求管理，都是一股脑的异步请求，，所以对于那种网络请求复杂的APP，请谨慎使用。
