4 示例代码(替换成您的AccessKeyId、AccessKeySecret、appKey)

详细解答可以参考官方帮助文档

    IClientProfile clientProfile = DefaultProfile.GetProfile("cn-hangzhou", "<your access key id>", "<your access key secret>");
    DefaultAcsClient client = new DefaultAcsClient(clientProfile);
    PushRequest request = new PushRequest();
    // 推送目标
    request.AppKey = <your appKey>;
    //推送目标: device:推送给设备; account:推送给指定帐号,tag:推送给自定义标签; all: 推送给全部
    request.Target = "all";
    //根据Target来设定，如Target=device, 则对应的值为 设备id1,设备id2. 多个值使用逗号分隔.(帐号与设备有一次最多100个的限制)
    request.TargetValue = "all";
    // 设备类型deviceType 取值范围为:0~3. iOS设备: 0; Android设备: 1; 全部: 3, 这是默认值.
    request.DeviceType = 1;
    // 推送配置
    // 0:表示消息(默认为0), 1:表示通知
    request.Type = 0;
    // 消息的标题
    request.Title = ".net Title";
    // 消息的内容
    request.Body = ".net body";
    // 通知的摘要
    request.Summary = ".net Summary";
    // 推送配置: iOS
    // iOS应用图标右上角角标
    request.IOSBadge = "1";
    // iOS通知声音
    request.IOSMusic = "default";
    //iOS通知标题(iOS 10+)
    request.IOSTitle = "iOS 10 Title";
    //iOS通知副标题(iOS 10+)
    request.IOSSubtitle = "iOS 10 Subtitle";
    //使能通知扩展处理(iOS 10+)
    request.IOSMutableContent = true;
    //设定通知Category
    request.IOSNotificationCategory = "test_category";
    //自定义的kv结构,开发者扩展用 针对iOS设备, iOS 10+ 可以用attachment关键字指定富媒体推送通知的资源Url
     request.IOSExtParameters = "{\"attachment\":\"https://xxxx.xxx/notification_pic.png\",\"key1\":\"value1\"}";
     request.ApnsEnv = "DEV";
    // 推送时设备不在线（既与移动推送的服务端的长连接通道不通），则这条推送会做为通知，通过苹果的APNs通道送达一次(发送通知时,Summary为通知的内容,Message不起作用)。注意：离线消息转通知仅适用于生产环境
    // request.Remind = false;
    // 推送配置: Android
    // 点击通知后动作,1:打开应用 2: 打开应用Activity 3:打开 url 4 :无跳转逻辑
    request.AndroidOpenType = "3";
    // Android收到推送后打开对应的url,仅仅当androidOpenType=3有效
    request.AndroidOpenUrl = "http://www.baidu.com";
    //设置该参数后启动小米托管弹窗功能，此处指定通知点击后跳转的Activity（托管弹窗的前提条件：1. 继承小米辅助通道；2. storeOffline设为true)
    //request.XiaomiActivity = "_Your_XiaoMi_Activity_";
    // 设定android类型设备通知的扩展属性
    request.AndroidExtParameters = "{\"k1\":\"android\",\"k2\":\"v2\"}";
    // 推送控制
    //String pushTime = DateTime.UtcNow.AddSeconds(3).ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");
    //request.PushTime = pushTime;//延迟3秒发送
    //String expireTime = DateTime.UtcNow.AddDays(2).ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");
    //request.ExpireTime = expireTime;//设置过期时间为2天
    //request.StoreOffline = false;
    try
       {
            PushResponse response = client.GetAcsResponse(request);
            Console.WriteLine("RequestId:" + response.RequestId);
            Console.WriteLine("ResponseId:"+response.ResponseId);
            Console.ReadLine();
        } catch (ServerException e)
        {
            Console.WriteLine(e.ErrorCode);
            Console.WriteLine(e.ErrorMessage);
            Console.ReadLine();
        } catch (ClientException e)
        {
            Console.WriteLine(e.ErrorCode);
            Console.WriteLine(e.ErrorMessage);
            Console.ReadLine();
        }
