HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
String cookie = request.getHeader(HttpHeader.AUTHORIZATION.asString());
HttpRequest httpRequest = new HttpRequest().setRequest(request);
String authCookie = String.format("%s=%s", session_id, cookie );
ServletRequest clientRequest = httpRequest.getRequest();
httpRequest.setCookies(authCookie );

I sent cookies in response. This is how I did it:
我发送了 cookie 作为回应。我是这样做的：
String contextPath = request.getContextPath();//We need this path to set cookie's path.
Cookie [] cookies = request.getCookies();
Cookie cookieToProcess = null;
for (Cookie cookie : cookies) {
//Search cookie you need.
if ("you-cookie-name".equals(cookie.getName()) && "your-coocie-path".equals(cookie.getPath())) {
cookieToProcess = cookie;
break;
}
}
if (cookieToProcess == null) {
//No such cookie.
//Possibly user enters your site for the first time or they disabled cookies.
//In this case we create a new cookie.
String cookieName = "your-cookie-name";
String cookieValue = "your-cookie-value";
Cookie newCookie = new Cookie(cookieName, cookieValue);
newCookie.setPath(contextPath);
response.addCookie(newCookie);
} else {
String cookieValue = cookieToProcess.getValue();//Retrieve value from the cookie.
}
If you want to redirect or forward your request to the next jsp, servlet, etc, add request attribute see Difference between getAttribute() and getParameter()
如果要将请求重定向或转发到下一个 jsp、servlet 等，请添加请求属性，请参阅getAttribute() 和 getParameter() 之间的区别
