Web 部件错误:(401) 未经授权
我有一个小程序,用于查询 Web 服务、使用 XSLT 转换结果并将其显示在 jQuery 控件中。当我将代码移动到 Web 部件中并部署它时,我收到以下错误:
The remote server returned an error: (401) Unauthorized.
这是加载我的 XSLT 文件的代码,这就是我怀疑问题所在的地方:
XPathDocument xPathDoc;
XsltArgumentList args;
protected override void OnPreRender(EventArgs e)
{
xPathDoc = QueryRunner.GetQueryResults();
args = QueryRunner.GetColumnsToShow();
}
public static XPathDocument GetQueryResults()
{
OpacAccess.OpacAccess proxy = new OpacAccess.OpacAccess();
string result = string.Empty;
try
{
result = proxy.query("CompanyName", "username", "password",
ReadingList=\"London\"", 1000);
}
catch (Exception ex)
{
}
// Store the xml of the result
XPathDocument xPathDoc = new XPathDocument(new StringReader(result));
return xPathDoc;
}
protected override void RenderContents(HtmlTextWriter output)
{
XslTransform xslt = new XslTransform();
// Load the xslt file and perform the transformation
xslt.Load("http://rginfonet/Style%20Library/XSL%20Style%20Sheets/Liberty.xslt");
xslt.Transform(xPathDoc, args, output, null);
output.Flush();
}
这是我的堆栈跟踪(如果有的话)对任何人都有帮助:

如果您能提供一些关于导致此问题的原因的见解,请告诉我。谢谢!
I have a little program that queries a web service, transforms the results using XSLT and displays them in a jQuery control. When I move the code into a web part it and deploy it, however I'm getting the following error:
The remote server returned an error: (401) Unauthorized.
This is the code that's loading my XSLT file, which is where I suspect the problem is:
XPathDocument xPathDoc;
XsltArgumentList args;
protected override void OnPreRender(EventArgs e)
{
xPathDoc = QueryRunner.GetQueryResults();
args = QueryRunner.GetColumnsToShow();
}
public static XPathDocument GetQueryResults()
{
OpacAccess.OpacAccess proxy = new OpacAccess.OpacAccess();
string result = string.Empty;
try
{
result = proxy.query("CompanyName", "username", "password",
ReadingList=\"London\"", 1000);
}
catch (Exception ex)
{
}
// Store the xml of the result
XPathDocument xPathDoc = new XPathDocument(new StringReader(result));
return xPathDoc;
}
protected override void RenderContents(HtmlTextWriter output)
{
XslTransform xslt = new XslTransform();
// Load the xslt file and perform the transformation
xslt.Load("http://rginfonet/Style%20Library/XSL%20Style%20Sheets/Liberty.xslt");
xslt.Transform(xPathDoc, args, output, null);
output.Flush();
}
Here's my stack trace if it's at all helpful to anyone:

负责呈现 Web 部件的帐户无权访问 xslt 所在的文档库。
有几种方法可以解决这个问题,
The account responsible for rendering the webpart does not have access to the document library where you have the xslt located.
There are a few ways to get around this,
如果您将 Web 部件部署在 bin 文件夹中,则该文件夹可能没有权限,无法向您显示 Web 部件。添加足够的权限。
If you deployed your webpart in the bin folder ,might be that folder won't have permissions and not able to show you the webpart.Add sufficient permissions.
