iOS-AFNetworking封装Get(自定义HTTP Header)和Post请求及文件下载

前面提到AFNetworking是一个很强大的网络三方库，首先你需要引入AFNetworking三方库；如封装的有误还请指出，谢谢！

1.Get请求

/**Get请求

 url 服务器请求地址

 success 服务器响应返回的结果

 faile  失败的信息

 */

+ (void)getHttpRequestURL:(NSString *)url RequestSuccess:(void(^)(id repoes,NSURLSessionDataTask *task)) success RequestFaile:(void(^)(NSError *error))faile{

   AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

   manager.responseSerializer = [AFHTTPResponseSerializer serializer];//放弃解析

    ///自定义http header 此处可省略

   /// [manager.requestSerializer setValue:@"application/json"forHTTPHeaderField:@"Accept"];

   /// [manager.requestSerializer setValue:@"application/json;charset=utf-8"forHTTPHeaderField:@"Content-Type"];

   /// [manager.requestSerializer setValue:@"http header" forHTTPHeaderField:@"XiaoGuiGe"];

    [manager.requestSerializer setHTTPShouldHandleCookies:NO];

    [manager GET:url parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {

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

        if (success) {

            //返回成功结果

            success(responseObject,task);

        }

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

        //返回失败结果

        faile(error);

    }];

}

2.Post请求

/**Post请求

 url 服务器请求地址

 pram 请求参数

 success 服务器响应返回的结果

 faile  失败的信息

 */

+ (void)postHttpRequestURL:(NSString *)url RequestPram:(id)pram RequestSuccess:(void(^)(id respoes))success RequestFaile:(void(^)(NSError *erro))faile{

   AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    [manager POST:url parameters:pram progress:^(NSProgress * _Nonnull uploadProgress) {

        ///这里面是进度

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

        if (success) {

            //返回成功结果

            success(responseObject);

        }

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

        //返回失败结果

        faile(error);

    }];

}

3.文件下载

+ (void)createDownloadFileWithURLString:(NSString *)URLString downloadFileProgress:(void (^)(NSProgress *))downloadFileProgress setupFilePath:(NSURL *(^)(NSURLResponse *))setupFilePath downloadCompletionHandler:(void (^)(NSURL *, NSError *))downloadCompletionHandler{

     NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:URLString]];

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    manager.requestSerializer = [AFHTTPRequestSerializer serializer];

    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    NSURLSessionDownloadTask *dataTask = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {

        /**

         *  下载进度

         */

        downloadFileProgress(downloadProgress);

    } destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {

        /**

         *  设置保存目录

         */        

        return setupFilePath(response);

    } completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) {

        /**

         *  下载完成

         */

        downloadCompletionHandler(filePath,error);

    }];

    [dataTask resume];

}

如有错误，还望指出！
