java獲取request的頭信息

1.獲取全部頭信息：

 //get request headers
  private Map<String, String> getHeadersInfo() {
    Map<String, String> map = new HashMap<String, String>();
    Enumeration headerNames = request.getHeaderNames();
    while (headerNames.hasMoreElements()) {
        String key = (String) headerNames.nextElement();
        String value = request.getHeader(key);
        map.put(key, value);
    }
    return map;
  }

 

2.獲取某個頭信息：

private String getHeader(String headerName) {
        return request.getHeader(headerName);
    }
