https请求出现Received fatal alert: handshake_failure异常解决

1.简述

　　使用Https请求知道链接时出现javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure异常，是因为ssl协议错误。

2.解决方案

　　主要是在创建SSLContext的时候指定TLS协议，就可以解决这个问题，使用的是httpclient-4.5.jar、httpcore-4.4.1.jar。

　　出现异常示例代码如下：

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.config.Registry;
import org.apache.http.config.RegistryBuilder;
import org.apache.http.conn.socket.ConnectionSocketFactory;
import org.apache.http.conn.socket.PlainConnectionSocketFactory;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
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.impl.conn.PoolingHttpClientConnectionManager;
import org.apache.http.ssl.SSLContextBuilder;
import org.apache.http.util.EntityUtils;

public class Demo {
    public static void main(String[] args) throws Exception {
        String url = "https://weather.com/weather/today/l/22.69,113.91?par=google";
        String result = "";
        CloseableHttpClient httpClient = null;
        try {
            SSLContextBuilder builder = new SSLContextBuilder();
            // 全部信任 不做身份鉴定
            builder.loadTrustMaterial(null, new TrustStrategy() {
                @Override
                public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                    return true;
                }
            });
            SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(), new String[] { "SSLv2Hello", "SSLv3", "TLSv1", "TLSv1.2" }, null, NoopHostnameVerifier.INSTANCE);
            Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory> create().register("http", new PlainConnectionSocketFactory()).register("https", sslsf).build();
            PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
            cm.setMaxTotal(200);// max connection
            httpClient = HttpClients.custom().setSSLSocketFactory(sslsf).setConnectionManager(cm).setConnectionManagerShared(true).build();
            HttpGet httpGet = new HttpGet(url);
            RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(30000).setConnectTimeout(30000).build();// 设置请求和传输超时时间
            httpGet.setConfig(requestConfig);
            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity resEntity = httpResponse.getEntity();
            result = EntityUtils.toString(resEntity);
        } catch (Exception e) {
            throw e;
        } finally {
            if (httpClient != null) {
                httpClient.close();
            }
        }
        System.out.println(result);
    }
}

            if (httpClient != null) {
                httpClient.close();
            }
        }
        System.out.println(result);
    }
}

　　第二种成功是因为去除了SSLv2Hello、SSLv3协议。

　　注意：三个示例中的最后一个输出记得屏蔽，因为内容较多不屏蔽则会卡一会。
