如何在 .Net Core 2 中为 IIS 发布定义自定义 web.config? [英] How to define custom web.config in .Net Core 2 for IIS publish?

问题描述

VS 将生成(并覆盖)一个 web.config 文件作为发布到 IIS 的一部分.我需要在文件中包含各种项目(例如扩展文件上传最大大小限制、重定向到 HTTPS 等).我目前必须在每次发布后将内容复制并粘贴到文件中.

VS will generate (and override) a web.config file as part of publishing to IIS. I have various items I need to include in the file (like extending the file upload max size limit, redirecting to HTTPS, etc.). I am currently having to copy and paste the contents into the file after every publish.

有没有办法定义 Visual Studio 在为 IIS 发布 .NET Core 2 Web 应用时生成的 web.config 文件的内容?

Is there a way to define the contents of the web.config file that Visual Studio generates when publishing a .NET Core 2 web app for IIS?

推荐答案

我终于回到了这个问题并使用了一个转换:

I finally got back to this and wound up using a transform:

1. 在项目根目录下创建 web.release.config 文件

1. Create a web.release.config file in the root of the project

将该文件的属性设置为 Build Action = None，这样它就不会被直接复制到目标文件夹

Set that file's properties to Build Action = None so it doesn't get copied directly to the destination folder

使用转换语法定义需要插入的部分:

Use the transformation syntax to define the sections that need to be inserted:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
  <location>
    <system.webServer>
      <security xdt:Transform="Insert">
        <requestFiltering>
          <requestLimits maxAllowedContentLength="209715200" />
        </requestFiltering>
      </security>
      <rewrite xdt:Transform="Insert">
        <rules>
          <rule name="HTTP/S to HTTPS Redirect" enabled="true" stopProcessing="true">
            <match url="(.*)" />
            <conditions logicalGrouping="MatchAny">
              <add input="{SERVER_PORT_SECURE}" pattern="^0$" />
            </conditions>
            <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" />
          </rule>
        </rules>
      </rewrite>
      <modules xdt:Transform="Insert" runAllManagedModulesForAllRequests="false">
        <remove name="WebDAVModule" />
      </modules>
    </system.webServer>
  </location>
</configuration>
