xamarin froms从Django rest框架解析JSON

如何解决xamarin froms从Django rest框架解析JSON

我可以在django网站上成功注册我的xamarin表单应用程序，如果用户名或电子邮件已经存在，我会以这种格式从django rest框架收到http响应：

{
"username": [
    "account with this username already exists."
],"email": [
    "account with this email already exists."
]

}

我想在显示警报中显示这些错误，而无需用户名和电子邮件。仅错误文本（例如：使用该用户名的帐户已经存在或使用此电子邮件的帐户已经存在）我尝试了很多方法来解析它，但是没有一个起作用。我该如何实现？

我的应用中的代码：

HttpClient client = new HttpClient();
        var values = new Dictionary<string,string>
        {
            { "username",EntryUsername.Text },{ "email",EntryEmail.Text },{ "password",EntryPassword1.Text },{ "password2",EntryPassword2.Text }
        };

        var content = new FormUrlEncodedContent(values);

        var response = await client.PostAsync("http://192.168.0.101:8000/api/account/register",content);

        var responseString = await response.Content.ReadAsstringAsync();

解决方法

使用Newtonsoft

var data = "{\"username\": [\"account with this username already exists.\"],\"email\": [\"account with this email already exists.\"]}";

var obj = JObject.Parse(data);
    
Console.WriteLine(obj["username"][0]);
Console.WriteLine(obj["email"][0]);
