Put、Delete、Get、Post封装方法设置请求头
还有获取用户权限以及登录请求的封装方法

先是不常用的吧（写的时候不是）
// GET超级api

+ (void)requestGETSuperAPIWithURLStr:(NSString *)urlStr WithAuthorization:(NSString *)authorization paramDic:(NSDictionary *)paramDic finish:(void(^)(id responseObject))finish enError:(void(^)(NSError *error))enError{

   // 设置请求头
   [manager.requestSerializer setValue:authorization forHTTPHeaderField:@"Authorization"];
