ASP.Net Core MVC需要< environmentVariables>在web.config中工作 [英] ASP.Net Core MVC needs <environmentVariables> in web.config to work

问题描述

我正在将我的ASP.Net Core 3.1 MVC项目发布到IIS.该项目包括一个Web api控制器以及mvc控制器.它将生成一个web.config文件，如下所示.发布后，该应用会显示该页面，但除非添加<环境变量>指向发展.如果我改用Production，它将无法正常工作.

I am publishing my ASP.Net Core 3.1 MVC project to IIS. The project includes a web api controller along with mvc controllers. It generates a web.config file as below. Once published, the app shows the page but the web api doesn't work unless I add the < environmentVariables > pointing to Development. If I put Production instead, it doesn't work.

已生成Web.config

Web.config Generated

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath=".\MyApp.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>

修改了Web.config:

Web.config Modified:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath=".\MyApp.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess">
        <environmentVariables>
            <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" />
        </environmentVariables>
      </aspNetCore>   
    </system.webServer>
  </location>
</configuration>

web.config的修改部分

Modified portion of web.config

<environmentVariables>
    <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" />
<environmentVariables>

推荐答案

将Visual Studio更新到v16.6.3，该版本刚刚发布(6月30日).它显然包括针对此问题的修复程序.我只是遇到了类似的问题，发布在这里:

Update Visual Studio to v16.6.3, which was just release (June 30). It apparently includes a fix for this issue. I just went through this similar problem, posted here:

为什么会从launchSettings.json中获取环境变量是否存在aspNetCore web.config部分时无法加载配置文件?
