- HttpServletRequest获取请求路径
- 1、 //Returns the part of this request‘s URL from the protocol name up to the query string in the first line of the HTTP request
- // eg. /ser.do?method=add_pre&type=mad
- String url = request.getRequestURI();
- return /ssm/ser.do
- 2、 //The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters
- //eg. http://localhost:8080/ssm/ser.do?method=add_pre&type=mad
- StringBuffer url_buffer = request.getRequestURL();
- return http://localhost:8080/ssm/ser.do
HttpServletRequest 的这两种方法都只能得到不包含参数的请求url，区别如下：
1 前者返回相对路径，后者返回完整路径
2 前者返回string ，后者返回stringbuffer
要想得到完整请求url可以通过如下方法，getQueryString()得到的是url后面的参数串，和前者相加就是带参数的请求路径了
- String queryString = request.getQueryString();
- String fullPath = url + queryString;
- // 或者是url_buffer.toString()+queryString;
- 即 /ssm/ser.do + method=add_pre&type=mad
