Question

我需要从HttpResponse获取响应uri并将其解析为名称 - 值对。我需要以下.NET片段的模拟：

string authorizationRequestParameters = string.Format("client_id={0}&response_type=code&scope={1}&access_type=offline", ClientID, Scope);
Uri authorizationRequestUri = new Uri(OauthHost.AbsoluteUri + "?" + authorizationRequestParameters);
HttpWebResponse authorizationResponse = DoGet(authorizationRequestUri, cookies);
NameValueCollection authorizeResponseParameters = HttpUtility.ParseQueryString(authorizationResponse.ResponseUri.Query);
string callbackCode = authorizeResponseParameters["code"];

必要条件是，在Java版本中，DoGet方法返回apache HttpResponse。我尝试这样做的方式：

HttpResponse resp = hch.doGet("http://...?client_id=...&response_type=...&scope=...&access_type=...");
HttpEntity entity = resp.getEntity();
InputStream instream = entity.getContent();
System.out.print(IOUtils.toString(instream, "UTF-8"));

我可以通过这种方式接收html内容，但我只需要响应包含参数的部分Uri。我怎么能这样做？

似乎HttpWebResponse.ResponseUri属性来自Content-Location标头，或者它是请求URI。所以这样的事情应该有效：

final String uri = "http://...?client_id=...&response_type=...&scope=...&access_type=...";
final HttpResponse resp = hch.doGet(uri);
final String contentLocation = resp.getFirstHeader ("Content-Location");
final String responseURI = contentLocation != null ? contentLocation : uri;

从apache HttpResponse获取响应Uri并解析它（java）
