我正在尝试使用Arm模板部署网站和sql azure，我正在尝试使用部署的数据库名称使用部署的网站转换sql连接字符串。创建了网站，部署了源代码并创建了sql azure数据库，但连接字符串不会被更改。 我在这里遵循了这个方法： https://github.com/Azure/azure-quickstart-templates/tree/master/201-web-app-sql-database
我的website.json看起来像这样：

}
},
"databaseName": {

}
}
}
我的web.config看起来像这样：
ml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-MyApp-20170201054732.mdf;Initial Catalog=aspnet-MyApp-20170201054732;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
有人能告诉我为什么DefaultConnection永远不会改变吗？

我刚刚部署了它，可以确认应用程序设置是否正确填充。 Web.config不应被此模板覆盖，模板会创建应用程序设置，应用程序将其读取：
如果您的web.config文件中已经存在应用程序设置，则Windows Azure网站将在运行时使用与您的网站关联的值自动覆盖它们。连接字符串以类似的方式工作，只需要很少的额外要求。请记住，之前有一个名为“example-config_db”的连接字符串已与网站关联。如果网站的web.config文件在配置部分中引用相同的连接字符串，则Windows Azure网站将使用门户中显示的值在运行时自动更新连接字符串。

DefaultConnection中的web.config连接字符串无法通过ARM部署进行更新，因为您实际上需要将web.config文件部署为MSDeploy包的一部分，并带有用于更新的参数DefaultConnection连接字符串，使用ARM模板中的MSDeploy扩展资源。
E.g。在MSDeploy Package parameters.xml中，您需要定义一个参数以允许更新名为DefaultConnection的连接字符串的值。
<parameter name="Default Connection String" description="Connection string to enter into config" tags="SQL, Hidden,NoStore">
<parameterEntry kind="XmlFile" scope="Web\.config$" match="//connectionStrings/add[@name='DefaultConnection']/@connectionString" />
</parameter>
除上述内容外，您还需要添加 MSDeploy扩展资源，该资源是您网站资源下的子资源，并设置默认连接字符串参数使用ARM模板中的Azure SQL连接字符串。
