c# - Pushbullet API 通知

Question

我想用 Pushbullet API 在 C# 中创建一个程序。

现在我从手机收到通知，但我想利用收到的数据。

如何分析和提取这样的数据：

{
  "push": {
    "application_name": "Pushbullet",
    "body": "If you see this on your computer, Android-to-PC notifications are working!\n",
    "client_version": 125,
    "dismissable": true,
    "has_root": false,
    "icon": "(base64_encoded_jpeg)",
    "notification_id": "-8",
    "notification_tag": null,
    "package_name": "com.pushbullet.android",
    "source_device_iden": "ujpah72o0sjAoRtnM0jc",
    "source_user_iden": "ujpah72o0",
    "title": "Mirroring test",
    "type": "mirror"
  },
  "type": "push"
}

我怎样才能阅读这样的代码？

正则表达式？

Answer 1

这是一个有效的.Net Fiddle => https://dotnetfiddle.net/9Lt67g

解决方案的详细信息：按照以下步骤操作。为了完整起见，整个代码也粘贴在末尾（以防 dotnetfiddle 出现故障或将来“死亡”）

步骤1

使用json2csharp.com或类似的东西从您的 JSON 响应中生成 C# POCO。这是我使用您提供的示例 JSON 生成的。

public class Push
{
    public string application_name { get; set; }
    public string body { get; set; }
    public int client_version { get; set; }
    public bool dismissable { get; set; }
    public bool has_root { get; set; }
    public string icon { get; set; }
    public string notification_id { get; set; }
    public object notification_tag { get; set; }
    public string package_name { get; set; }
    public string source_device_iden { get; set; }
    public string source_user_iden { get; set; }
    public string title { get; set; }
    public string type { get; set; }
}

public class RootObject
{
    public Push push { get; set; }
    public string type { get; set; }
}

第2步

使用 JSON.Net 将 JSON 反序列化为您的 POCO

Notification notification = JsonConvert.DeserializeObject<Notification>(json);
Console.WriteLine("PushBullet API Notification...");
Console.WriteLine("   App Name: {0}", notification.push.application_name);
Console.WriteLine("   Notification Body: {0}", notification.push.body);
// .... etc. you get the idea. You now have the notification in a POCO and do 
// whatever you want with it :)

这是控制台输出：

（注意，您需要Newtonsoft.Json通过包管理器控制台使用 Nuget 添加到您的项目中。）

public class Notification
