IOS 開發 AFNetworking 網絡工具-網絡請求的三次封裝 OC版

NetworkTool.h

親測可用,能正常擷取資料(已背景傳回的json資料作為測試的)

項目實測

//網絡請求
- (void)addNetworkData {
    NSString *URLString = [NSString stringWithFormat:@"%@",BaseURLString];

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

    NSDictionary *parameters = @{
                                 @"token":token
                                 };
    //使用第三次封裝的類方法--類名直接調用,簡潔明了                             
        [NetworkTool requestWithType:requestTypePOST URLString:URLString parameters:parameters success:^(id  _Nullable responseObject) {
    ZYLog(@"%@",responseObject);
    } failure:^(NSError *_Nonnull error) {

    }];
}
           

ZYLog(@”%@”,responseObject);的輸出結果

// MARK: 彈框
- (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)( * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [alert dismissViewControllerAnimated:YES completion:nil];
        });
    }];
}
           

調用第一次封裝的效果

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

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        [self sendUIAlertControllerWithTitle:@"使用者資訊擷取失敗" message:@"網絡延遲/系統繁忙"];
    }];
           

調用第二次封裝的效果

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

        //傳回的資料處理
    } failure:^(NSError * _Nonnull error) {
        [self sendUIAlertControllerWithTitle:@"使用者資訊擷取失敗" message:@"網絡延遲/系統繁忙"];
    }];
