本文介绍了Java获取此次请求URL以及获取服务器根路径的方法,并且进行举例说明,感兴趣的朋友可以学习借鉴下文的内容。
一、 获取此次请求的URL
String requestUrl = request.getScheme() //当前链接使用的协议 +\"://\" + request.getServerName()//服务器地址 + \":\" + request.getServerPort() //端口号 + request.getContextPath() //应用名称,如果应用名称为 + request.getServletPath() //请求的相对url + \"?\" + request.getQueryString(); //请求参数
举例:
http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1 <Context path=\"world\" docBase=\"/home/webapps\" debug=\"0\" reloadable=\"true\"/> request.getScheme() = \"http\"; request.getServerName() = \"127.0.0.1\"; request.getServerPort() = \"8080\"; request.getContextPath() = \"world\"; request.getServletPath() = \"index.jsp\"; request.getQueryString() = \"name=lilei&sex=1\"; http://127.0.0.1:8080/world/index.jsp?name=lilei&sex=1 <Context path=\"\" docBase=\"/home/webapps\" debug=\"0\" reloadable=\"true\"/> request.getScheme() = \"http\"; request.getServerName() = \"127.0.0.1\"; request.getServerPort() = \"8080\"; request.getContextPath() = \"\"; request.getServletPath() = \"world/index.jsp\"; request.getQueryString() = \"name=lilei&sex=1\";
二、获取服务器根路径
<% String path = request.getContextPath(); String basePath = request.getScheme()+\"://\"+request.getServerName()+\":\"+request.getServerPort()+path+\"/\"; %>
使用如下:
<head> <link rel=\"stylesheet\" type=\"text/css\" href=\"<%=basePath%>static/css/framework/themes/default/easyui.css\"> <link rel=\"stylesheet\" type=\"text/css\" href=\"<%=basePath%>static/css/framework/themes/icon.css\"> <link rel=\"stylesheet\" type=\"text/css\" href=\"<%=basePath%>static/css/base.css\"> <script src=\"<%=basePath%>static/javascript/framework/jquery.min.js\"></script> <script src=\"<%=basePath%>static/javascript/framework/jquery.easyui.min.js\"></script> <script src=\"<%=basePath%>static/javascript/framework/easyui-lang-zh_CN.js\"></script> <script src=\"<%=basePath%>static/javascript/framework/easyui-util.js\"></script> </head>
以上就是Java获取此次请求URL以及服务器根路径的方法,希望对大家的学习有所帮助。
