更改 nopCommerce 的连接字符串？

Question

我正在使用 nopCommerce，我需要删除 settings.txt 文件中的连接字符串并插入 web.config 文件。我怎样才能做到这一点？

Answer 1

将连接字符串从 settings.txt 移到 web.config 的最直接方法是修改Nop.Core.Data.DataSettingsManager. 具体方法LoadSettings()和SaveSettings()方法。您可以将连接字符串存储在您想要的任何位置（最好在 web.config 中），只要这两种方法读取和写入配置即可。

DataSettingsManager可以在此 Gist 中找到支持在 web.config 中存储连接字符串的更新的粗略示例：http : //git.io/vUPcI只需将连接字符串从 settings.txt 复制到 web.config 并命名连接“ DefaultConnection”或相应地调整代码。

只需做两步

1. 替代两个方法LoadSettings，并SaveSettings在\nopCommerce\Libraries\Nop.Core\Data\DataSettingsManager.cs。来自@Stephen Kiningham 链接的代码

   /// <summary>
   /// Load settings
   /// </summary>
   /// <param name="filePath">File path; pass null to use default settings file path</param>
   /// <returns></returns>
   public virtual DataSettings LoadSettings(string filePath = null)
   {            
       try
       {
           System.Configuration.Configuration webConfig = WebConfigurationManager.OpenWebConfiguration(HttpRuntime.AppDomainAppVirtualPath);
           return new DataSettings
           {
               DataConnectionString = webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ConnectionString,
               DataProvider = webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ProviderName
           };
       }
       catch (NullReferenceException)
       {
           return new DataSettings();
       }
   }
   
   /// <summary>
   /// Save settings to a file
   /// </summary>
   /// <param name="settings"></param>
   public virtual void SaveSettings(DataSettings settings)
   {            
       if (null == settings) throw new ArgumentNullException("settings");
   
       System.Configuration.Configuration webConfig = WebConfigurationManager.OpenWebConfiguration(HttpRuntime.AppDomainAppVirtualPath);
   
       webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ConnectionString = settings.DataConnectionString;
       webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ProviderName = settings.DataProvider;
   
       webConfig.Save();
   }
   

2. 将连接字符串添加到您的网络配置 web.config

   /// <summary>
   /// Load settings
   /// </summary>
   /// <param name="filePath">File path; pass null to use default settings file path</param>
   /// <returns></returns>
   public virtual DataSettings LoadSettings(string filePath = null)
   {            
       try
       {
           System.Configuration.Configuration webConfig = WebConfigurationManager.OpenWebConfiguration(HttpRuntime.AppDomainAppVirtualPath);
           return new DataSettings
           {
               DataConnectionString = webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ConnectionString,
               DataProvider = webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ProviderName
           };
       }
       catch (NullReferenceException)
       {
           return new DataSettings();
       }
   }
   
   /// <summary>
   /// Save settings to a file
   /// </summary>
   /// <param name="settings"></param>
   public virtual void SaveSettings(DataSettings settings)
   {            
       if (null == settings) throw new ArgumentNullException("settings");
   
       System.Configuration.Configuration webConfig = WebConfigurationManager.OpenWebConfiguration(HttpRuntime.AppDomainAppVirtualPath);
   
       webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ConnectionString = settings.DataConnectionString;
       webConfig.ConnectionStrings.ConnectionStrings["DefaultConnection"].ProviderName = settings.DataProvider;
   
       webConfig.Save();
   }
   

Answer 3

请将其添加到 Nop.Web 项目下的 web.config 中：

<connectionStrings>
<add name="MyConnectionString" 
connectionString="Data Source=serverName;Initial Catalog=DBName;Persist Security Info=False;UserID=userName;Password=password" 
</connectionStrings>

此致。
