爬網頁遇到一些問題為什麼爬ptt網頁版他會跳出 SSLHandshakeException 我google了一下很多啊六都說是證書的問題應該是license吧如果是因為沒有license那我要怎麼解決這個問題呢?? 貼一下大部分遇到的錯誤訊息 at sun.security.ssl.Alerts.getSSLException(Alerts.java:192) at sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1949) at sun.security.ssl.Handshaker.fatalSE(Handshaker.java:302) at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387) at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory. java:543) at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory. java:409) at org.apache.http.impl.conn.DefaultClientConnectionOperator. openConnection(DefaultClientConnectionOperator.java:177) at org.apache.http.impl.conn.ManagedClientConnectionImpl. open(ManagedClientConnectionImpl.java:304) 我是用這樣的方法去爬的 webcatch(String website,String filename) throws IOException { FileWriter fw=new FileWriter(filename); BufferedWriter bw=new BufferedWriter(fw); HttpClient httpclient =new DefaultHttpClient(); HttpGet httpget =new HttpGet(website); HttpResponse response =httpclient.execute(httpget); String responseString =EntityUtils.toString(response.getEntity()); if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { bw.write(responseString); } else { System.out.println(response.getStatusLine()); } 只有爬ptt會遇到這個問題有什麼解決的方法呢???麻煩了 --
