Question

我正在尝试将带有GET请求的JSON列表加载到我的localhost（WAMP）上的PHP文件到我的Silverlight + Webproj解决方案中：

HttpWebRequest request = WebRequest.Create(uri) as HttpWebRequest;
request.BeginGetRequestStream(GetRequestStreamCallback, request);

    private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
    {
        HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
        Stream postStream = request.EndGetRequestStream(asynchronousResult);

        byte[] byteArray = Encoding.UTF8.GetBytes(postInformation);
        postStream.Write(byteArray, 0, postInformation.Length);
        postStream.Close();
        request.BeginGetResponse(DownloadCompleted, request);
    }

    private void DownloadCompleted(IAsyncResult asynchronousResult)
    {
        ... load the data from the response , etc
}

这对于另一个网站来说完全相同。但现在我得到了这个安全例外：

{System.Security.SecurityException ---> System.Security.SecurityException: Security error.
   at System.Net.Browser.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncResult     asyncResult)
   at System.Net.Browser.BrowserHttpWebRequest.<>c__DisplayClassa.    <EndGetResponse>b__9(Object sendState)
   at System.Net.Browser.AsyncHelper.<>c__DisplayClass4.<BeginOnUI>b__0(Object sendState)
   --- End of inner exception stack trace ---
    at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallback beginMethod, Object state)
   at System.Net.Browser.BrowserHttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at KunstWebsite.Model.Factory`1.DownloadCompleted(IAsyncResult asynchronousResult)}

我尝试了一些解决方案，我发现像添加clientaccesspolicy.xml，crossdomain.xml，将localhost作为可信站点，将trust level =“Full”添加到我的web.config中。它们似乎都不起作用......

任何人都知道我可能忽略了什么？
