java request获取各种数据

我们经常需要在servlet(j2ee13.jar javax.servlet.http.HttpServletRequest)中，获取请求request的各种数据信息。

请求的URL: http://10.63.205.120:7001/undwrt/GetRealIP?param=a
可通过下面代码:

/**
* 通过servlet获取客户端请求request的URL
* http://10.63.205.120:7001/undwrt/GetRealIP?param=a * */
protected void getURL(HttpServletRequest request){
int ContentLength= request.getContentLength();
String ContentType= request.getContentType();
String CharacterEncoding= request.getCharacterEncoding();
String AuthType= request.getAuthType();
String Method= request.getMethod();
String RemoteAddr= request.getRemoteAddr();
String PathInfo= request.getPathInfo();
String ServerName= request.getServerName();
String Protocol= request.getProtocol();
String QueryString= request.getQueryString();
String RequestURI= request.getRequestURI();
String Scheme= request.getScheme();
int ServerPort= request.getServerPort();
String ServletPath= request.getServletPath();

String RequestURL= request.getRequestURL().toString();
String ContextPath= request.getContextPath();

System.out.println("ContentLength :"+ContentLength);
System.out.println("ContentType :"+ContentType);
System.out.println("CharacterEncoding :"+CharacterEncoding);
System.out.println("AuthType :"+AuthType);
System.out.println("Method :"+Method);
System.out.println("RemoteAddr :"+RemoteAddr);
System.out.println("PathInfo :"+PathInfo);
System.out.println("ServerName :"+ServerName);
System.out.println("Protocol :"+Protocol);
System.out.println("QueryString :"+QueryString);
System.out.println("RequestURI :"+RequestURI);
System.out.println("Scheme :"+Scheme);
System.out.println("ServerPort :"+ServerPort);
System.out.println("ServletPath :"+ServletPath);

System.out.println("RequestURL :"+RequestURL);
System.out.println("ContextPath :"+ContextPath);
}

run as:
ContentLength :-1
ContentType :null
CharacterEncoding :GBK
AuthType :null
Method :GET
RemoteAddr :10.63.205.79
PathInfo :null
ServerName :10.63.205.120
Protocol :HTTP/1.1
QueryString :param=a
RequestURI :/undwrt/GetRealIP
Scheme :http
ServerPort :7001
ServletPath :/GetRealIP
RequestURL :http://10.63.205.120:7001/undwrt/GetRealIP
ContextPath :/undwrt
