如何使用JSoup或HttpConnection获取响应的确切状态代码？

Question

Whenever I try to get the status code of a particular URL, both JSoup and HttpConnection always returns 200 even if there is a 301/302 redirect for the request URL. Did anyone else face a similar issue and what should be the workaround to get the status code of the first request?

Answer 1

The general strategy if you want to see redirection status codes is to turn off automatic redirect following. If you then want to follow the redirects, you can do it yourself ... by hand ... after making a note of the status code.

The details will depend on what you are using; eg HttpUrlConnection, Apache HttpClient v3, Apache HttpClient v4, or something else.

• With HttpUrlConnection, call HttpUrlConnection.setFollowRedirects(false) - note that this a static method that affects all future connection attempts.
• With HttpClient v3, call HttpMethod.setFollowRedirects(false) .
• With HttpClient v4, you could supply a custom RedirectStrategy , or disable redirect handling with HttpClientBuilder.disableRedirectHandling() .
• With JSoup, you apparently call Connection.followRedirects(false) .
