Answer 1

还没到登录，在下载验证码的时候已经报异常了，代码如下：import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;import javax.net.ssl.SSLContext;import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.SSLContextBuilder;
import org.apache.http.conn.ssl.TrustStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;public class XiaMen_IS
{ public static void main(String[] args)
{
crawler();
} // 信息抓取
public static void crawler()
{
try
{ CloseableHttpClient cbHttpClient = createSSLInsecureClient();
getVerficationCode(cbHttpClient);
} catch (Exception e)
{
System.out.println("---厦门社保抓取失败---");
}
} // 获取验证码
private static String getVerficationCode(CloseableHttpClient cbHttpClient) throws Exception
{
try
{
String url = "https://app.xmhrss.gov.cn/wcm/servlet/VCodeServlet";// 验证码地址
HttpGet get = new HttpGet(url);
HttpResponse response = cbHttpClient.execute(get);// 报异常
// 获取验证码字节数组
byte data[] = EntityUtils.toByteArray(response.getEntity()); } catch (Exception e)
{
System.out.println("厦门社保下载验证码异常:");
e.printStackTrace();
throw e;
} return null;
} // client工具函数，信任对方（https）所有证书
public static CloseableHttpClient createSSLInsecureClient()
{
try
{
// 创建安全套接字对象
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy()
{
// 信任所有
public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException
{
return true;
}
}).build();
// 获取分层tls/ssl连接
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
return HttpClients.custom().setSSLSocketFactory(sslsf).build();
} catch (KeyManagementException e)
{
e.printStackTrace();
} catch (NoSuchAlgorithmException e)
{
e.printStackTrace();
} catch (KeyStoreException e)
{
e.printStackTrace();
}
return HttpClients.createDefault();
}}

Answer 2

将
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
改为
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,new String[] {"SSLv3"}, null, SSLConnectionSocketFactory.getDefaultHostnameVerifier());亲测已经可以把验证码下载下来了。

Answer 3

报语法错误httpclient用的什么版本？
我用4.4运行的，org.apache.http.conn.ssl.SSLConnectionSocketFactory。

Answer 4

我又下了个httpclient-4.3.4.jar改成
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext,new String[] {"SSLv3"}, null, null);
就可以了啊
