使用使用JSP读取客户端信息读取客户端信息
使用JSP读取客户端信息
请阅读以下代码。如果你的使用要求不同，可对这些代码加以很方便的修改。这些代码可以使你获得：
公司company, 用户name，版本version，main version，minor version
操作系统(未完成!)，语言language，locale等。
建立一个新的JSP文件:
请将下列class文件加入classpath (你要建立同样的目录结构– de.hunsicker.http.util，当然也可以自己调节包的名称。!):
package de.hunsicker.http.util;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Browser extends HttpServlet
{
protected HttpServletRequest request;
protected HttpSession session;
protected String userAgent;
protected String company; // Firmenname des Herstellers
protected String name; // Bezeichnung des Browsers
protected String version; // Version
protected String mainVersion; // Hauptversion
protected String minorVersion; // Unterversion
protected String os; // Betriebssystem
protected String language = \"de\"; // Sprachcode Standard
protected Locale locale; // Locale-Objekt mit den aktuellen
// Spracheinstellungen
private Hashtable supportedLanguages; // Untersttzte Sprachen
public Browser(HttpServletRequest request, HttpSession session)
{
this.initialize();
this.request = request;
this.session = session;
this.setUserAgent(this.request.getHeader(\"User-Agent\"));
this.setCompany();
this.setName();
this.setVersion();
this.setMainVersion();
this.setMinorVersion();
this.setOs();
this.setLanguage();
this.setLocale();
}
public void initialize()
{
this.supportedLanguages = new Hashtable(2);
this.supportedLanguages.put(\"en\", \"\");
this.supportedLanguages.put(\"de\", \"\");
}
public void setUserAgent(String httpUserAgent)
{
this.userAgent = httpUserAgent.toLowerCase();
}
private void setCompany()
{
if (this.userAgent.indexOf(\"msie\") > -1)
{
this.company = \"Microsoft\";
}
else if (this.userAgent.indexOf(\"opera\") > -1)
{
this.company = \"Opera Software\";
}
else if (this.userAgent.indexOf(\"mozilla\") > -1)
{
this.company = \"Netscape Communications\";
}
