Asp.net Mvc 3 连接字符串问题

Question

我刚刚为我的网络应用程序创建了一些托管空间。但是，当我更改连接字符串以指向提供商的 SQL 服务器时，我收到错误。

该字符串如下：

   <connectionStrings>
    <add name="ApplicationServices" connectionString="Data Source=d5d3955e-1183-4e10-8892-9f9d005af0a8.sqlserver.sequelizer.com;Initial Catalog=dbd5d3955e11834e1088929f9d005af0a8;Persist Security Info=True;User ID=juydqjglrdwrhgsr;Password=***********" providerName="System.Data.SqlClient" />
  <add name="TraxzDBEntities" connectionString="metadata=res://*/Models.DBModel.csdl|res://*/Models.DBModel.ssdl|res://*/Models.DBModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=d5d3955e-1183-4e10-8892-9f9d005af0a8.sqlserver.sequelizer.com;Initial Catalog=dbd5d3955e11834e1088929f9d005af0a8;Persist Security Info=True;User ID=juydqjglrdwrhgsr;Password=***********&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>

我收到这个奇怪的错误：

Login failed for user 'juydqjglrdwrhgsr'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

我假设连接字符串做错了什么，任何人都可以对此发表一些见解吗？需要启动并运行此托管才能继续我的学校项目。 :)

更新：我正在使用 AppHarbor 进行托管，我一直在寻找这个问题并发现了这一点：

  If you take advantage of the Sequelizer MySQL and MS SQL Server add-ons, SQLSERVER_CONNECTION_STRING and SQLSERVER_URI settings will be injected into your application appSettings. SQLSERVER_CONNECTION_STRING_ALIAS will also be inserted if you add an alias. Further, the connection string will be placed in the connectionStrings element with name set to the alias if one is specified.

The uri is of the following format: sqlserver://username:password@hostname/databasename. If you want, you can create your own connection string (if, for example, you need a custom one for Entity Framework). Here's an example of building a standard connection string:

var uriString = ConfigurationManager.AppSettings["SQLSERVER_URI"];
var uri = new Uri(uriString);
var connectionString = new SqlConnectionStringBuilder
{
    DataSource = uri.Host,
    InitialCatalog = uri.AbsolutePath.Trim('/'),
    UserID = uri.UserInfo.Split(':').First(),
    Password = uri.UserInfo.Split(':').Last(),
}.ConnectionString;

我不知道这真正意味着什么..我需要添加新的连接字符串吗？如果是这样，我如何创建一个映射到我创建的实体？

通过修改 applicationServices 连接字符串修复了该问题：

<add name="TraxzDBEntities" connectionString="metadata=res://*/Models.DBModel.csdl|res://*/Models.DBModel.ssdl|res://*/Models.DBModel.msl;
         provider=System.Data.SqlClient;
         provider connection string="
         Data Source=YOURPROVIDERDATASOURCE;
         User ID=YourUserName; 
         Password=YourPassword;
         Initial Catalog=YourCatalog;
         Persist Security Info=True;
      MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />

然后在 .tt 类下，对我来说它是“Dbcontext.context.tt”，我们添加以下内容

   string baseConnectionString = ConfigurationManager.ConnectionStrings["TraxzDBEntities"].ConnectionString;

    EntityConnectionStringBuilder entityBuilder = new EntityConnectionStringBuilder();
    entityBuilder.Provider = "System.Data.SqlClient";
    entityBuilder.ProviderConnectionString = baseConnectionString;
    entityBuilder.Metadata = @"res://*/";

    return entityBuilder.ToString();
