AFHTTPSessionManager : AFURLSessionManager 继承
是AFURLSessionManager的遍历方法

 NSURL *baseURL = [NSURL URLWithString:@"http://example.com/v1/"];
    [NSURL URLWithString:@"foo" relativeToURL:baseURL];                  // http://example.com/v1/foo
    [NSURL URLWithString:@"foo?bar=baz" relativeToURL:baseURL];          // http://example.com/v1/foo?bar=baz
    [NSURL URLWithString:@"/foo" relativeToURL:baseURL];                 // http://example.com/foo
    [NSURL URLWithString:@"foo/" relativeToURL:baseURL];                 // http://example.com/v1/foo
    [NSURL URLWithString:@"/foo/" relativeToURL:baseURL];                // http://example.com/foo/
    [NSURL URLWithString:@"http://example2.com/" relativeToURL:baseURL]; // http://example2.com/

baseURL 的讲解

// 下面是基本属性
@property (readonly, nonatomic, strong, nullable) NSURL *baseURL; // 基本的baseURL 
@property (nonatomic, strong) AFHTTPRequestSerializer <AFURLRequestSerialization> * requestSerializer; // 请求系列化
@property (nonatomic, strong) AFHTTPResponseSerializer <AFURLResponseSerialization> * responseSerializer; // 响应系列化
@property (nonatomic, strong) AFSecurityPolicy *securityPolicy; // 安全策略
+ (instancetype)manager; // 单例的管理者
- (instancetype)initWithBaseURL:(nullable NSURL *)url; // 初始化基础的baseURL
- (instancetype)initWithBaseURL:(nullable NSURL *)url
           sessionConfiguration:(nullable NSURLSessionConfiguration *)configuration NS_DESIGNATED_INITIALIZER; // 基于url进行配置configuration


// GET 、 Head 、POST（基本数据post， martipart数据post）、PUT、PATCH、DELETE、


/**

 @param failure 失败的回调

 @see -dataTaskWithRequest:uploadProgress:downloadProgress:completionHandler:
 */
- (nullable NSURLSessionDataTask *)dataTaskWithHTTPMethod:(NSString *)method
                                                URLString:(NSString *)URLString
                                               parameters:(nullable id)parameters
                                                  headers:(nullable NSDictionary <NSString *, NSString *> *)headers
                                           uploadProgress:(nullable void (^)(NSProgress *uploadProgress))uploadProgress
                                         downloadProgress:(nullable void (^)(NSProgress *downloadProgress))downloadProgress
                                                  success:(nullable void (^)(NSURLSessionDataTask *task, id _Nullable responseObject))success
                                                  failure:(nullable void (^)(NSURLSessionDataTask * _Nullable task, NSError *error))failure;

PS :
1 ) 对AFURLSessionManager 底层的方法封装，对get、post等便利的方法
2 ) 上传文件内容 , 这个调用的是上传的

AFURLSessionManager 的接口
