HttpServletRequest獲取請求引數
阿新 • • 發佈:2019-01-02
通過HttpServletRequest接收請求來的引數,
get請求
public class controller1 {
@RequestMapping(value = "/", method = {RequestMethod.POST})
public String con001(HttpServletRequest request) throws IOException {
Map<String, String> param = getAllRequestParam(request);
String queryString = request.getQueryString();
String user = request.getParameter("user");
String pass = request.getParameter("pass");
System.out.println(user);
System.out.println(param);
return "hello";
}
post請求
先獲取到引數名的集合,在組裝到Map裡
private Map<String, String> getAllRequestParam(final HttpServletRequest request) {
Map<String, String> res = new HashMap<String, String>();
Enumeration<?> temp = request.getParameterNames();
if (null != temp) {
while (temp.hasMoreElements()) {
String en = (String) temp.nextElement();
String value = request.getParameter(en);
res.put(en, value);
}
}
return res;
}
