Csharp 将 Api 连接到 WebGl (SmarterAsp.net) 上的 Unity 项目

因此，我一直在try 将Unity项目与API连接起来，并将其构建在WebGL平台上. 在Android、Windows App和WebGL IN Unity上，它运行得很好，但当我在WebGL平台上构建它时，它就不能运行了. 查看下面的API链接进行测试: http://syriatech07-001-site1.htempurl.com/Users个

我已经找到了解决方案，但我不知道如何应用它，就是在标题中添加一个HOST. 我试过这个接口"https://httpbin.org/get""，它运行得很好. 如果需要更多的信息，请让我知道.

Edit:
Here's the connection code:

IEnumerator GetDataCoroutineASync()
{
    // Showing the result
    outPutArea.text = "Loading.....";

    string uri = "http://syriatech07-001-site1.htempurl.com/Users";
    using (UnityWebRequest request = UnityWebRequest.Get(uri))
    {
        request.SetRequestHeader("Host", "syriatech07-001-site1.htempurl.com");
        request.SetRequestHeader("Access-Control-Allow-Methods", "*");
        request.SetRequestHeader("Access-Control-Allow-Headers", "append,delete,entries,foreach,get,has,keys,set,values,Authorization,Origin, Content-Type, X-Auth-Token,Accept, X-Requested-With, Access-Control-Request-Method, Access-Control-Request-Headers");
        request.SetRequestHeader("Access-Control-Allow-Origin", "*");

        var op = request.SendWebRequest();

        yield return op;

        if (request.isNetworkError)
        { outPutArea.text = "isNetworkError"; }
        else if (request.isHttpError)
        { outPutArea.text = "isHttpError"; }
        else
        { outPutArea.text = request.downloadHandler.text; }
    }
}
