这是我在 Acumatica 24R2 中测试时使用的简单示例代码，响应为空

我向 Acumatica 提出了支持案例，并收到了解决该问题的解决方案。

Acumatica 建议在 SubmitApproval 中传递 webhookRequest 而不是 webhookResponse 以达到预期结果。

**private string SubmitApproval(string collectorID, PX.Api.Webhooks.WebhookRequest request)**
{
    string body = string.Empty;
    Stream stream = request.Body;
    stream.Position = 0;
    using (StreamReader reader = new StreamReader(stream))
    {
        // Read the entire stream to a string
        body = reader.ReadToEnd();
    }
    string values = collectorID;
    string[] arr = values.Split(new char[] { ';' });
    string trantype = arr[0];
    string doctype = arr[1];
    string docnbr = arr[2];
    bool authorize = false;
    arr = body.Split(new char[] { '&' });
    foreach (string node in arr)
    {
        string[] element = node.Split(new char[] { '=' });
        switch (element[0].ToLower())
        {
            case "cbauthorize": authorize = (element[1].ToLower() == "on"); break;
            default: break;
        }
    }
    SOOrderEntry g = PXGraph.CreateInstance<SOOrderEntry>();
    SOOrder ord = SOOrder.PK.Find(g, doctype, docnbr);
    if(ord != null)
    {
        WHSOOrderExt ext = ord.GetExtension<WHSOOrderExt>();
        ext.UsrApprove = authorize;
        ext.UsrHits = (ext.UsrHits ?? 0) + 1;
        g.Document.Update(ord);
        g.Save.Press();
    }
    var view = @"
           <!DOCTYPE html>
            <html>
            <body>
               <h1>Approval</h1>
              Thank You Your Submitted your answer was {0}
            </body>
       </html>
           ";
    return string.Format(view,((authorize)?"Yes":"No"));
}
