  • request获取各种路径

    1、request.getRequestURL() 返回的是完整的url,包括Http协议,端口号,servlet名字和映射路径,但它不包含请求参数。

    2、request.getRequestURI() 得到的是request URL的部分值,并且web容器没有decode过的

    3、request.getContextPath() 返回 the context of the request.

    4、request.getServletPath() 返回调用servlet的部分url.

    5、request.getQueryString() 返回url路径后面的查询字符串

    示例: 当前url:http://localhost:8080/CarsiLogCenter_new/idpstat.jsp?action=idp.sptopn

    request.getRequestURL() :http://localhost:8080/CarsiLogCenter_new/idpstat.jsp

    request.getRequestURI() :/CarsiLogCenter_new/idpstat.jsp

    request.getContextPath():/CarsiLogCenter_new

    request.getServletPath(): /idpstat.jsp

    request.getQueryString():action=idp.sptopn
