如何在Azure Web App的自定义部分中覆盖web.config值? [英] How to override web.config values in custom section in Azure Web App?

问题描述

在Azure Web App中可以轻松覆盖web.config AppSettings部分.例如.如果我有以下web.config:

It is possible in Azure Web App to override web.config AppSettings section easily. E.g. if I have the following web.config:

<appSettings>   
    <add key="AllowedCORSOrigin" value="http://localhost:26674"/>
</appSettings>

我可以在门户网站的应用程序设置UI中覆盖它，

I can override it in the app settings UI in the portal like that:

我在web.config中也有一个自定义部分:

I have also a custom section in the web.config:

<AdWordsApi>
    <add key="OAuth2RefreshToken" value="TOKEN" />
</AdWordsApi>

是否有可能以某种方式覆盖它?我已经尝试过AdWordsApi.OAuth2RefreshToken和AdWordsApi:OAuth2RefreshToken，但这并不容易.

Is it possible to override it somehow as well? I have tried AdWordsApi.OAuth2RefreshToken and AdWordsApi:OAuth2RefreshToken, but that does not work that easily.

P.S.知道其他自定义部分是否可行，例如是否要在服务器上使用其他身份验证模式，这很有趣.

P.S. It's interesting to know if it's possible with other custom sections like e.g if I want another authentication mode on the server.

<system.web>
    <authentication mode="None" />
</system.web>

推荐答案

简短的回答是这是不可能的.

Short answer is that it is not possible.

您描述的机制仅适用于应用程序设置"和连接字符串".高层次，它的工作方式是:

The mechanism you describes only works with App Settings and Connection Strings. High level, the way it works is:

• 您的Azure应用设置成为环境变量
• 在运行时，一个特殊的模块在.NET config系统中动态设置这些参数.请注意，物理web.config从未修改.

但是要使这种机制适用于任意配置节将很困难，因为如果不修改物理文件就无法动态影响这些配置节.

But it would be hard to make such mechanism work on arbitrary config sections, as those could not be dynamically affected without modifying the physical file.
