Obtaining URL from http response when no location header is sent
提问by joepetrakovich
When communicating with http to http://forecast.weather.gov/zipcity.phpI need to obtain the URL that is generated from a request.
当与 http 通信到http://forecast.weather.gov/zipcity.php 时，我需要获取从请求生成的 URL。
I have printed out the headers and their values from the http response message but there is no location header. How can I obtain this URL? (I'm using HttpClient)
我已经从 http 响应消息中打印出标头及其值，但没有位置标头。我怎样才能获得这个网址？（我正在使用 HttpClient）

It should be similar to:
它应该类似于：
HttpClient client = new DefaultHttpClient();
HttpParams params = client.getParams();
HttpClientParams.setRedirecting(params, false);
HttpGet method = new HttpGet("http://forecast.weather.gov/zipcity.php?inputstring=90210");
HttpResponse resp = client.execute(method);
String location = resp.getLastHeader("Location").getValue();
EDIT: I had to make a couple minor tweaks, but I tested and the above works.
编辑：我不得不做一些小的调整，但我测试了上面的工作。
