目录上的“401未授权”

我假设这是一个 IIS 错误，因为如果在本地计算机上运行项目，就不会发生这种情况。

我在 ~/Content/css有样式表

该目录中的任何文件都不会在页面上加载，当我直接导航到它们时，会得到一个服务器错误:

401-未授权: 由于凭据无效，访问被拒绝。

您没有使用所提供的凭据查看此目录或页的权限。

这只发生在该目录，我没有问题访问任何其他文件。我需要在 IIS7中做些什么来阻止这一切吗？

You need to check the folder permissions on your server and check that the account that you are using to run your application has access to that folder.

It is likely that you do not have the IUSR_computername permission on that folder. I've just had a quick scan and it looks like you will find the information you need here.

If that isn't the case, are you prompted for your username and password by the browser? If so it may be that IIS is configured to use Integrated authentication only, as described here.

Another simple fix I found was to delete the local IIS site (from within IIS Manager) and then re-create the virtual directory from the "Properties" of your web project in Visual Studio.

  1. Open IIS and select site that is causing 401
  2. Select Authentication property in IIS Header
  3. Select Anonymous Authentication
  4. Right click on it, select Edit and choose Application pool identity
  5. Restart site and it should work

You do not have permision to view this directory or page using the credentials that you supplied.

This happened despite the fact the user is already authenticated via Active Directory.

There can be many causes to Access Denied error, but if you think you’ve already configured everything correctly from your web application, there might be a little detail that’s forgotten. Make sure you give the proper permission to Authenticated Users to access your web application directory.

Here are the steps I took to solve this issue.

  1. Right-click on the directory where the web application is stored and select Properties and click on Security tab.

  2. Click on Click on Edit…, then Add… button. Type in Authenticated Users in the Enter the object names to select., then Add button. Type in Authenticated Users in the Enter the object names to select.

  3. Click OK and you should see Authenticated Users as one of the user names. Give proper permissions on the Permissions for Authenticated Users box on the lower end if they’re not checked already.

  4. Click OK twice to close the dialog box. It should take effect immediately, but if you want to be sure, you can restart IIS for your web application.

Refresh your browser and it should display the web page now.

Hope this helps!

For me the Anonymous User access was fine at the server level, but varied at just one of my "virtual" folders.

Took me quite a bit of foundering about and then some help from a colleague to learn that IIS has "authentication" settings at the virtual folder level too - hopefully this helps someone else with my predicament.

In our case it was Windows-integrated authentication specified in the app's web.config

BUT the windows-auth module was not installed on the IIS machine at all.

Just adding another possible reason.
