How to set cookie from CookieManager when using HttpUrlConnection?

Question

I'm perform a http request with some cookie, My code like this:

HttpURLConnection conn = (HttpURLConnection) u.openConnection();
CookieManager cookieManager = new CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
cookieManager.getCookieStore().add(....);//here to set cookie
CookieHandler.setDefault(cookieManager);
// do request in following

But I can't find my cookie by fiddler. I have search many questions in stackoverflow, none of them work through. So, please help me to find the way to set cookie.

PS I don't want to use Cookie header.

最后，我发现了问题，在我的代码中，应在任何Http操作之前调用CookieHandler.setDefault（），而应在u.openConnection()之前u.openConnection() 。
