CefSharp Javascript 回調從不返回已解決 promise

Question

首先，請原諒我的英語，它非常糟糕。 我在 WinForms 應用程序中使用 CefSharp 在導航器和 .NET 代碼之間進行通信。

I'm trying to resolve a promise in an asynchronous callback function with CefSharp, but in the response returned to.Net I never get the response of the resolved promise, but rather an object that seems to represent the consumers of said promise (finally,抓住，然后）。

有沒有辦法解決這個問題？

我留下一個例子，希望能幫助你理解這個問題。

//C#代碼

public void TestCallback(IJavascriptCallback javascriptCallback)
{
    const int taskDelay = 1500;
    Task.Run(async () =>
    {
        await Task.Delay(taskDelay);
        using (javascriptCallback)
        {
            var result = await javascriptCallback.ExecuteAsync();
            //result is a JavaScriptResponse, but property "Result" is not "user" object, is a dictionary object with 'then', 'catch', 'finally' keys. 
        }
    });
}

//JS代碼

function async MyCallback()
{
  // read our JSON
  let response = await fetch('/article/promise-chaining/user.json');
  let user = await response.json();
  return user;
}
boundAsync.testCallback(MyCallback);

非常感謝。

現在，在 cefsharp 的 88 版中已經解決了這個問題： https://github.com/cefsharp/CefSharp/wiki/Advanced-Async-JavaScript-Binding-(JSB)/07c45fa962174d0476c4f2206f707365e9b11edd#javascript-callback-with-
