Request获取各种路径总结

// 常见Request获取路径集合
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String remoteAddress = request.getRemoteAddr();
String servletPath = request.getServletPath();
String realPath = request.getRealPath("/");
String remoteUser = request.getRemoteUser();
String requestURI = request.getRequestURI();
out.println("path:"+path+"<br>");
out.println("basePath:"+basePath+"<br>");
out.println("remoteAddr:"+remoteAddress+"<br>");
out.println("servletPath:"+servletPath+"<br>");
out.println("realPath:"+realPath+"<br>");
out.println("remoteUser:"+remoteUser+"<br>");
out.println("requestURI:"+requestURI+"<br>");
