Request—url参数解析

请求地址： http://localhost:8080/test?name=11&pwd=33
代码示例：

@RequestMapping("test")
public void getParam(HttpServletRequest request,String name,String pwd) {
    // 输出参数
    System.out.println("name = " + name + ", pwd = " + pwd);
    // 获取url输入的地址
    String requestURL = request.getRequestURL().toString().trim();
    System.out.println("获取url输入的地址：" + requestURL);
    // 获取uri
    System.out.println("获取uri地址：" + request.getRequestURI());

    // 获取参数
    Enumeration enu=request.getParameterNames();
    while(enu.hasMoreElements()){
        // 参数名
        String paraName=(String)enu.nextElement();
        String parameterVal = request.getParameter(paraName);
        System.out.println(paraName + ": " + parameterVal);
    }

    try {
        URL url = new URL(requestURL);
        System.out.println("host = " + url.getHost());
        System.out.println("port = " + url.getPort());
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

结果：

name = 11, pwd = 33
获取url输入的地址：http://localhost:8080/test
获取uri地址：/test
name: 11
pwd: 33
host = localhost
port = 8080
