https Java SSL Exception protocol_version

    在java代码中，使用HttpClient爬取https页面时，遇到了这个bug：javax.net.ssl.SSLException: Received fatal alert: protocol_version

      先奉上初始的代码：

29     HttpClient client = HttpClients.createDefault();
30     HttpRequestBase http = new HttpGet(url);
31     HttpContext context = new BasicHttpContext();
32     try {
33       HttpResponse response = client.execute(http, context);
34       int statusCode = response.getStatusLine().getStatusCode();
35 
36       switch (statusCode) {
37         case 200:
38         case 400:// 业务异常
39           break;
40         default:
41           throw new HttpException(url + " Status Code:" + statusCode);
42       }
43 
44       HttpEntity entity = response.getEntity();
45       String reStr = EntityUtils.toString(entity);
46       System.out.println(reStr);
47     } catch (Exception e) {
48       System.out.println(e.toString());
49     }
50   }

 注：加上System.setProperty("javax.net.debug", "all");这一行是为了查看调试信息。

86 javax.net.ssl.SSLException: Received fatal alert: protocol_version

 

重点是这一行：

*** ClientHello, TLSv1

这个表示我们使用的默认的http协议班本是：TLSv1，错误提示意思是http协议版本不正确。

于是，我按照stackoverflow上的分析，增加协议版本："SSLv2Hello"

改版后的代码：

8 ======>WeatherCrawler getCurrentWeather errorjavax.net.ssl.SSLException: Received fatal alert: protocol_version

到了这里，问题还是没有解决，报错信息跟之前一样，没有进展。

于是，我对照着下面表格，一直尝试协议的组合，直到尝试到{"SSLv2Hello", "TLSv1.2"}的组合，才抓取到页面的html代码。后来发现只用 "TLSv1.2"即可抓取到页面。

SSLContext Algorithms

The algorithm names in this section can be specified when generating an instance of SSLContext.

Algorithm Name	Description
SSL	Supports some version of SSL; may support other versions
SSLv2	Supports SSL version 2 or later; may support other versions
SSLv3	Supports SSL version 3; may support other versions
TLS	Supports some version of TLS; may support other versions
TLSv1	Supports RFC 2246: TLS version 1.0 ; may support other versions
TLSv1.1	Supports RFC 4346: TLS version 1.1 ; may support other versions
TLSv1.2	Supports RFC 5246: TLS version 1.2 ; may support other versions
SSLv2Hello	Currently, the SSLv3, TLSv1, and TLSv1.1 protocols allow you to send SSLv3, TLSv1, and TLSv1.1 hellos encapsulated in an SSLv2 format hello. For more details on the reasons for allowing this compatibility in these protocols, see Appendix E in the appropriate RFCs (previously listed). Note that some SSL/TLS servers do not support the v2 hello format and require that client hellos conform to the SSLv3 or TLSv1 client hello formats. The SSLv2Hello option controls the SSLv2 encapsulation. If SSLv2Hello is disabled on the client, then all outgoing messages will conform to the SSLv3/TLSv1 client hello format. If SSLv2Hello is disabled on the server, then all incoming messages must conform to the SSLv3/TLSv1 client hello format.
