使用flurl向OneSignal api发送通知

Question

我正在尝试使用onesignal页面中的示例发送一些数据

var request = WebRequest.Create("https://onesignal.com/api/v1/notifications") as HttpWebRequest;

request.KeepAlive = true;
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";

request.Headers.Add("authorization", "Basic xxx");

var obj = new
{
    app_id = "xxx",
    contents = new { en = "English Message" },
    included_segments = new string[] { "Active Users" }
};
var param = JsonConvert.SerializeObject(obj);
byte[] byteArray = Encoding.UTF8.GetBytes(param);

使用此代码工作正常但我使用Flurl向这样的信号发出请求

var body = new
{
    app_id = "xxx",
    contents = new
    {
        es = "Mensaje prueba"

    },
    included_segments = new string[] { "All" }
};
string param = JsonConvert.SerializeObject(body);
var content = new System.Net.Http.ByteArrayContent(Encoding.UTF8.GetBytes(param));

var response = await new Flurl.Url(urlbase)
    .AppendPathSegment("notifications")
    .WithHeader("Content-Type", "application/json; charset=utf-8")
    .WithHeader("Authorization", "Basic xxx")
    .PostAsync(content)
    .ReceiveString();

但是我得到了“糟糕的请求”。请有人帮忙指出如何与Flurl进行相同的通话？

正如第一条评论中所提到的，你做的工作超出了你的需要。 Flurl会为你序列化body，所以删除这些行：

string param = JsonConvert.SerializeObject(body);
var content = new System.Net.Http.ByteArrayContent(Encoding.UTF8.GetBytes(param));

并使用body直接发布PostJsonAsync：

var response = await urlbase
    ...
    .PostJsonAsync(body)
    .ReceiveString();
