Question

我正在使用Java和Apache HttpClient编写播客下载程序。它适用于大多数RSS提要，但是这个提示失败并显示“406 Not Acceptable”错误。

我得到的回应是：

HttpResponseProxy{HTTP/1.1 406 Not Acceptable [Server: nginx/1.12.0, Date: Sat, 03 Jun 2017 03:40:17 GMT, Content-Type: text/html; charset=iso-8859-1, Content-Length: 226, Connection: keep-alive] ResponseEntityProxy{[Content-Type: text/html; charset=iso-8859-1,Content-Length: 226,Chunked: false]}}

我的Java代码是：

   HttpClient httpClient = HttpClients.custom().setUserAgent( "Mozilla/5.0" ).build();
   HttpGet httpGet = new HttpGet( url );
   httpGet.setHeader( "Accept", "*/*" );
   httpGet.setHeader( "Accept-Encoding", "gzip, deflate, sdch" );
   httpGet.setHeader( "Accept-Language", "en-US,en;q=0.8" );
   HttpResponse httpResponse = httpClient.execute( httpGet );
   return httpResponse.getEntity();

我不确定如何调试这个。大多数帖子都说错误的接受标题。我已经让我接受了一切，但仍然失败了。

当我在Chrome中访问该网站时，我会收到以下标题。可能是导致问题的304返回码吗？

我还能尝试什么？

Answer 1

它似乎检查了User-Agent。我让它与以下用户代理一起工作：

CloseableHttpClient httpClient = HttpClients.custom().setUserAgent( "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36" ).build();

Apache HttpClient接收“406 Not Acceptable”错误
