Change the connection string of nopCommerce?

问题

I am using nopCommerce and I need to remove the connection string in the settings.txt file and insert the web.config file. How can i do this?

回答1:

The most straightforward way to move the connection string out of settings.txt and into the web.config is to modify the Nop.Core.Data.DataSettingsManager. Specifically the LoadSettings() and SaveSettings() methods. You can store the connection string wherever you'd like (ideally in web.config), as long as those two methods read and write the configuration.

A rough example of the DataSettingsManager updated to support storing the connection string in web.config can be found in this Gist: http://git.io/vUPcI Just copy the connection string from settings.txt to web.config and name the connection "DefaultConnection" or adapt the code accordingly.

Just do two steps

Replace two method LoadSettings and SaveSettings in \nopCommerce\Libraries\Nop.Core\Data\DataSettingsManager.cs. Code from link of @Stephen Kiningham

/// <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();
}

Add connection string to your web config web.config

<connectionStrings>
    <add name="DefaultConnection"
         connectionString=" Data Source=localhost;Initial Catalog=nopcommerce;Integrated Security=True;Persist Security Info=False"
         providerName="sqlserver">
    </add>
</connectionStrings>

回答3:

In addition to adding the connection to the web.config, you have to specify the providerName="sqlserver".

Ex) ;Initial Catalog=;Integrated Security=False;User ID=;Password=;Connect Timeout=30;Encrypt=True" providerName="sqlserver" />

This is because the EfDataProviderManager in Nop.Data has a check for the provider name, and will throw an exception if you put the normal

providerName="System.Data.SqlClient"

回答4:

Please add this to your web.config under Nop.Web project :

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

Best Regards.
