Apache HttpClient接收“406不可接受”错误

Question

我正在编写一个使用Java和Apache HttpClient的播客下载器。它适用于大多数RSS提要，但这一个失败了，出现了“406不可以接受”的错误。

链接是http://sqrpt.com/feed/podcast/

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]}}

   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();

Answer 1

它似乎检查了用户代理。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();
