IOS 开发 AFNetworking 网络工具-网络请求的三次封装 OC版

NetworkTool.h

亲测可用,能正常获取数据(已后台返回的json数据作为测试的)

//单例

//第一次封装参数比较多,比较长

                failure:(nullable void (^)(NSURLSessionDataTask * _Nullable task, NSError *_Nonnull error))failure;

//第二次封装,简化参数,把没有用的progress参数去掉
- (void)requestWithType:(requestType)type URLString:(nonnull NSString *)URLString parameters:(nullable id)parameters success:(nullable void (^)(id _Nullable responseObject))success  failure:(nullable void (^)(NSError *_Nonnull error))failure;

//第三次封装,直接使用类方法,外部调用单例都不用创建
+ (void)requestWithType:(requestType)type URLString:(nonnull NSString *)URLString parameters:(nullable id)parameters success:(nullable void (^)(id _Nullable responseObject))success  failure:(nullable void (^)(NSError *_Nonnull error))failure;

项目实测

//网络请求
- (void)addNetworkData {
    NSString *URLString = [NSString stringWithFormat:@"%@",BaseURLString];

    NSString *token = [[NSUserDefaults standardUserDefaults] objectForKey:@"token"];

    NSDictionary *parameters = @{
                                 @"token":token
                                 };
    //使用第三次封装的类方法--类名直接调用,简洁明了                             
        [NetworkTool requestWithType:requestTypePOST URLString:URLString parameters:parameters success:^(id  _Nullable responseObject) {
    ZYLog(@"%@",responseObject);
    } failure:^(NSError *_Nonnull error) {

    }];
}

ZYLog(@”%@”,responseObject);的输出结果

// MARK: 弹框
- (void)sendUIAlertControllerWithTitle:(NSString *)title message:(NSString *)message {
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    [self presentViewController:alert animated:YES completion:^{
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [alert dismissViewControllerAnimated:YES completion:nil];
        });
    }];
}

调用第一次封装的效果

    [[NetworkTool shareNetworkTool] requestWithType:requestTypePOST URLString:URLString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nullable task, id  _Nullable responseObject) {
        //处理返回的json

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        [self sendUIAlertControllerWithTitle:@"用户信息获取失败" message:@"网络延迟/系统繁忙"];
    }];

调用第二次封装的效果

    [[NetworkTool shareNetworkTool] requestWithType:requestTypePOST URLString:URLString parameters:parameters success:^(id  _Nullable responseObject) {

        //返回的数据处理
    } failure:^(NSError * _Nonnull error) {
        [self sendUIAlertControllerWithTitle:@"用户信息获取失败" message:@"网络延迟/系统繁忙"];
    }];
