webmagic创始人回答：
code4craft commented on 29 Nov 2017 • 更新会在0.7.4版本发布。 临时适配方式，修改HttpClientGenerator中的buildSSLConnectionSocketFactory方法， return new SSLConnectionSocketFactory(createIgnoreVerifySSL(), new String[]{"SSLv3", "TLSv1", "TLSv1.1", "TLSv1.2"}, null, new DefaultHostnameVerifier())
WebMagic默认的HttpClient只会用TLSv1去请求，对于某些只支持TLS1.2的站点（例如 https://juejin.im/） ，就会报错： javax.net.ssl.SSLException: Received fatal alert: protocol_version at sun.security.ssl.Alerts.getSSLException(Alerts.java:208) at sun.security.ssl.Alerts.getSSLException(Alerts.java:154) at sun.security.ssl.SSLSocketImpl.recvAlert(SSLSocketImpl.java:2023) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1125) at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1375) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1403) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387) at org.apache.http.conn.ssl.SSLConnectionSocketFactory.createLayeredSocket(SSLConnectionSocketFactory.java:394) at org.apache.http.conn.ssl.SSLConnectionSocketFactory.connectSocket(SSLConnectionSocketFactory.java:353) at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:141) at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:353) at org.apache.http.impl.execchain.MainClientExec.establishRoute(MainClientExec.java:380) at org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:236) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:184) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:88) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:110) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:184) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at us.codecraft.webmagic.downloader.HttpClientDownloader.download(HttpClientDownloader.java:85) 现在的修改方式是在HttpClientGenerator中构建SSLConnectionSocketFactory时加上支持。
