Azure应用程序从machine.config中获取连接字符串

我已经在MS Azure上部署了一个MVC应用程序作为App Service。

在上次更新之前它运行正常，现在我得到的错误是应用程序从connectionString而不是machine.config中的web.config获取machine.config。

  1. 我知道不建议您修改machine.config

  2. 即使我想;我无法更改值，因为我无法访问<clear />文件。

    3. 我已尝试在<connectionStrings> web.config的{​​{1}}开头添加web.api，但不知何故应用程序的一部分/视图有效（我只是在哪里）使用network related or instance specific error填充客户端页面），但是当使用服务器端的控制器填充页面/视图时，它会抛出错误（SQL错误：LocalSqlServer）。

    应用程序以某种方式引用名为<?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,

的连接字符串。但是，我没有在整个应用程序中提到具有该名称的连接字符串。

    调试的问题在于，应用程序在本地实例上完美运行，但不适用于生产。

    这是我的连接字符串的样子：

    当我从connectionString

我认为这与你在web.config中有<roleManager enabled="true">有关，但没有配置它。这导致它使用来自machine.config的MySQLRoleProvider部分，该部分引用connectionStringName="LocalMySqlServer"。相反，您应该使用自己的数据库配置角色管理器。

e.g。来自doc page，你应该有这样的东西：

<roleManager enabled ="true"   
             defaultProvider ="SqlRoleProvider" >  
  <providers>  
    <add name ="SqlRoleProvider"   
         type="System.Web.Security.SqlRoleProvider"   
         connectionStringName="SqlConn"   
         applicationName="MembershipAndRoleProviderSample"/>  
  </providers>  
</roleManager>

答案 1 :(得分：0)

此问题与RoleManager相关，但设置为true，但未提供defaultProvider。感谢@DavidEbbo的pointing out。

这使服务器从machine.config中选择相同的内容。

现在，正如我的评论中提到的那样，ASP Membership确实适用于ASP Identity，但当前的应用程序使用Roles，因此无法正常工作。

实际上我必须编写自己的逻辑来处理应用程序中的RoleProvider，因为使用集成的RoleProvider更多的是我需要实现的简单登录的冗余。截至目前，当前的应用程序不再使用集成的RoleProvider，而是使用自定义的block_blob_service.put_block_list。
