Question

我们在Azure上有一个nodeJS webapp，它运行正常。

流式传输服务器日志时，每次加载页面时，所有资源（图像，css等）上都会出现一堆404错误。但是页面仍可以正确显示。

详细错误显示如下：

Requested URL      https://[myappname]:80/settings.png
Physical Path      D:\home\site\wwwroot\settings.png
Logon Method       Anonymous
Logon User     Anonymous

请求的URL显然是错误的，应该为https://[myappname].azurewebsites.net/settings.png，它是给定资源的公共URL，并且可以正常工作。此问题将加载大量日志，因此目前无法使用Web Server日志。

谢谢！

编辑：与this problem不同，我的页面正确加载并且资源文件可用。

已解决 ：我已将以下处理程序添加到我的web.config中：

<add name="UrlRoutingModule-4.0" path="*" verb="*" type="System.Web.Routing.UrlRoutingModule" preCondition="" />

我相信您需要在web.config中为静态文件内容配置一个规则集。

 <rule name="StaticContent">
                         <action type="Rewrite" url="public{REQUEST_URI}"/>
                    </rule>

在Azure Web Apps上运行的

Node.js应用程序通过IISNode托管在IIS上。因此，需要一个web.config文件在IIS上配置您的应用程序。如果您通过Continuous Deployment将应用程序部署到Azure App Service，则Azure将自动生成web.config文件。或者，您可以从此处下载文件。

我发布默认的web.config仅供参考”

Answer 2

感谢您的回答。

我有几乎相同的web.config，是自动生成的。您指出的规则略有不同：

    <rule name="StaticContent">
      <action type="Rewrite" url="public{PATH_INFO}"/>
    </rule>

我的服务器代码包括：

app.use(express.static(path.join(__dirname, 'public')));
