c# - 成员资格远程连接字符串在 SQL Server Management Studio 中有效但在 ASP.NET 中无效(错误 26)

Question

我在将 ASP.NET 的默认成员连接字符串更改为远程连接字符串时遇到问题。这是我尝试使用的连接字符串:

Data Source=myserver.com;Integrated Security=True;Initial Catalog=database_name;User ID=username;Password=password

数据库托管在共享主机上，可以通过 SQL Server Management Studio 访问，我还使用记事本方法等测试了完全相同的连接字符串...

所以，我几乎可以肯定问题不是我的连接字符串，而是 web.config 中的其他内容。这是 web.config 文件:

这是我收到的错误的屏幕截图:

你需要改成这样:

<membership defaultProvider="DefaultMembershipProvider">
    <providers>
        <clear/>
        <add ...

我还注意到您的连接字符串有 Data Source=xxxxxxx.com，我假设您只是为了发布而阻止了它，但它真的以 .com 结尾吗？您确定完全限定的 .com 地址可以从您的 Web 服务器解析吗？
