SharePoint2013与SharePoint2016语言切换原理以及如何使用代码进行语言切换

1、前言

SharePoint 2010版本,在首页面直接"选择显示语言"的菜单(如下图所示),如下图 :

在sharepoint2013和sharepoint2016并非如此。

  1. 这里首先需要安装语言包,SharePoint2016语言包下载地址:

https://www.microsoft.com/en-us/download/details.aspx?id=51492

SharePoint2013语言包下载地址:

https://www.microsoft.com/zh-cn/download/details.aspx?id=37140

 

注意:下载安装完毕后都要进行重新配置

 

  1. 在【网站设置】-【语言设置】设置备用语言,这里为英语,如下图

     

  2. 进行【关于我】进行【语言区域设置】如下图:

     

     

     

2、原理

上面说到SharePoint2010的语言切换根据记录cookie的方式可以快速进行切换,只要记录cookie的值lcid值,对于SharePoint2013和SharePoint2016的语言采用此方式不行,根据IE语言版本来确定显示哪个语言?,因此我们这里使用Fiddler工具进行http头文件的获取分析,主要分析:Accept-Language

说明:

Accept-Language:浏览器所希望的语言种类,当服务器能够提供一种以上的语言版本时要用到;根据http头的情况,用代码修改Accept-Language的设置来模拟设置语言版本的切换

  1. 我们打开英文站点:http://sp2016 用Fiddler抓取分析,如下图:

    分析结果:

  2. 我们打开中文站点:http://sp2016(切换后)的Fiddler抓取图,如下图:

既然知道这个原理,切换代码把每次要切换的语言版本保存到cookie值里,那么我们第一次系统用代码切换前cookie值为空设置一个默认为中文,使用httpModule方式来分析http头的Accept-Language的值,如果包含en-US就设置为英文版本,如果包含zh-CN就设置为中文。明白原理写代码就方便多了。

3、代码

  1. HttpModule.cs源码如下:

       

using System;

using System.Web;

using System.Web.UI;

using Microsoft.SharePoint;

using System.Threading;

using Microsoft.SharePoint.Utilities;

 

namespace CSSharePointLangSwitcher.LangSwitcherPage

{

public class HTTPSwitcherModule : IHttpModule

{

/// <summary>

/// You will need to configure this module in the web.config file of your

/// web and register it with IIS before being able to use it. For more information

/// see the following link: http://go.microsoft.com/?linkid=8101007

/// </summary>

#region IHttpModule Members

 

public void Dispose()

{

//clean-up code here.

}

 

/// <summary>

/// Init event

/// </summary>

/// <param name="context"></param>

public void Init(HttpApplication context)

{

// Below is an example of how you can handle Request event and provide

// custom logging implementation for it

context.PreRequestHandlerExecute += context_PreRequestHandlerExecute;

}

 

#endregion

 

/// <summary>

/// Assuming the selected language is stored in a cookie. Firstly, get the selected

/// language from cookie. Then add the selected language to the request header.

/// Finally, use the selected language for the current culture.

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

void context_PreRequestHandlerExecute(object sender, EventArgs e)

{

// Get current application.

HttpApplication httpApp = sender as HttpApplication;

 

// Get all HTTP-specific information about current HTTP request.

HttpContext context = httpApp.Context;

 

// Current language.

string strLanguage = string.Empty;

 

// The key of current selected language in the cookies.

string strKeyName = "LangSwitcher_Setting";

 

try

{

// Set the current language.

if (httpApp.Request.Cookies[strKeyName] != null)

{

strLanguage = httpApp.Request.Cookies[strKeyName].Value;

}

else

{

strLanguage = "zh-cn";

}

 

var lang = context.Request.Headers["Accept-Language"];

if (lang != null)

{

if (!lang.Contains(strLanguage))

context.Request.Headers["Accept-Language"] = strLanguage + "," + context.Request.Headers["Accept-Language"];

 

var culture = new System.Globalization.CultureInfo(strLanguage);

 

// Apply the culture.

SPUtility.SetThreadCulture(culture, culture);

}

}

catch (Exception ex)

{

System.Diagnostics.Debug.WriteLine(ex.Message);

}

}

}

}

 

 

 

  1. 切换代码如下:
    /// <summary>
    
    /// Save current selected language to cookie.
    
    /// </summary>
    
    /// <param name="sender"></param>
    
    /// <param name="e"></param>
    
    protected void btnSave_Click(object sender, EventArgs e)
    
    {
    
    if (ddlLanguages.SelectedIndex > 0)
    
    {
    
    // Selected language.
    
    string strLanguage = ddlLanguages.SelectedValue;
    
     
    
    // Set the Cookies.
    
    HttpCookie acookie = new HttpCookie(strKeyName);
    
    acookie.Value = strLanguage;
    
    acookie.Expires = DateTime.MaxValue;
    
    Response.Cookies.Add(acookie);
    
     
    
    Response.Redirect(Request.RawUrl);
    
    }
    
    }

     

4、效果

  1. 测试切换效果,先测试切换到中文,如下:

切换后,我们访问下http://sp2016 为中文效果,如下图:

  1. 测试切换效果,先测试切换到英文,如下:

切换后,我们访问下http://sp2016 为英文效果,如下图:
