iOS新鲜的AFNetworking3使用方法

post请求

.h里面声明方法

+ (void)postRequestWithUrl:(NSString
*)urlString params:(NSDictionary *)params completion:(void(^)(id
result))completionBlock failure:(void(^)(void))failureBlock;

.m里面实现方法

// post请求

+ (void)postRequestWithUrl:(NSString *)urlString params:(NSDictionary *)params completion:(void (^)(id))completionBlock
failure:(void (^)(void))failureBlock

{

    // 1、创建请求管理者

    AFHTTPSessionManager *manager = [AFHTTPSessionManagermanager];

   
// 2、数据反序列化（因为在进行请求服务器之前会对参数进行一次参数序列化）

    manager.responseSerializer = [AFHTTPResponseSerializerserializer];

    // 3、开始请求

    [manager POST:urlString
parameters:params progress:^(NSProgress *_Nonnull uploadProgress) {

          // 上传进度        

  NSLog(@"uploadProgress%@", uploadProgress);

    } success:^(NSURLSessionDataTask *_Nonnull task,
id _Nullable responseObject) {

  //解析数据

          NSDictionary *obj = [NSJSONSerializationJSONObjectWithData:responseObject
options:NSJSONReadingMutableContainerserror:nil];

        

        completionBlock(obj);

    } failure:^(NSURLSessionDataTask *_Nullable task,
NSError *_Nonnull error) {

        NSLog(@"网络连接失败");

        NSLog(@"%@", task.response.URL);

    }];

}

至于get请求，换个方法就好了
