Cannot get 'location' header in response using HttpClient

Question

The location header is there, I can see it in browser:

I'm using org.apache.httpcomponents.httpclient to send http request with cookie:

```

URI uri = new URIBuilder().setScheme("https").setHost("api.weibo.com").setPath("/oauth2/authorize").setParameter("client_id","3099336849").setParameter("redirect_uri","http://45.78.24.83/authorize").setParameter("response_type", "code").build();
HttpGet req1 = new HttpGet(uri);
RequestConfig config = RequestConfig.custom().setRedirectsEnabled(false).build();
req1.setConfig(config);
req1.setHeader("Connection", "keep-alive");
req1.setHeader("Cookie", cookie);
req1.setHeader("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36");
response = httpclient.execute(req1);

```

I googled a lot and tried enable/disable auto redirect,but it doesn't seem to work for me.So can somebody tell me how to get the location header in response just like the browser did?

Please share the code you used for trying to disable redirect. — Jan

You cannot see 'location' header, because HttpClient followed that redirect immediately - even before giving you that response.

Try disabling redirect while setting up your HttpClient:

HttpClient instance = HttpClientBuilder.create().disableRedirectHandling().build();

Check this URL and you'll see the Location Header:

URI uri = new URIBuilder().setScheme("https").setHost("www.googlemail.com").setPath("/").build();

api.weibo.com/oauth2/… I got this page.It seems like I didn't authorized when I use the HttpClient to send request.

Okay - I tried your code with browser and with code and got response 200 both times as well.

So it's not HttpClient not receiving location Header, it's the server not sending it

So I cannot skip auth process with cookie?

That's a whole new question... Try setting all the headers your browser sent inside your code.

I found out my real question...I didn't pass the auth process in my code,so I keep getting oauth2 page.After I set all the headers in my request just like the browser did and finally I get the right response.
