Question

向www.sunnyportal.com发送获取请求时，控制台中出现错误代码，如下所示：

    javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure
at sun.security.ssl.Alerts.getSSLException(Alerts.java:192)

我试了以下几页没有运气：

+ Received fatal alert: handshake_failure through SSLHandshakeException

+ How to solve javax.net.ssl.SSLHandshakeException Error?

这是我的代码：

package personal.Project;

    import java.io.IOException;

    import java.io.InputStream;

    import java.net.MalformedURLException;

    import java.net.URL;

    import java.net.URLConnection;

    import java.net.URLEncoder;

    public class GetUrl {

        private String url = "https://www.sunnyportal.com/Templates/ChartValues.aspx";

private String charset = "UTF-8";  // Or in Java 7 and later, use the constant: java.nio.charset.StandardCharsets.UTF_8.name()
private String login = "<>";
private String password = "<>";

public String getReq() throws MalformedURLException, IOException
{
    String query = String.format("login=%s&password=%s", 

            URLEncoder.encode(login, charset), 
            URLEncoder.encode(password, charset));

        URLConnection c = new URL(url + "?" + query).openConnection();
        c.setRequestProperty("Accept-Charset", charset);
        InputStream response = c.getInputStream();  

        return response.toString();
}
public static void main (String args[])
{
    GetUrl data = new GetUrl();
    String getString = null;
    try {
        getString = data.getReq();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        System.exit(1);
    }

    System.out.println( getString );
}

}

希望能帮助解决这个问题，提前谢谢！

根据https://www.ssllabs.com/ssltest/analyze.html?d=sunnyportal.com，服务器只协商一个密码套件TLS_RSA_WITH_AES_256_CBC_SHA，它使用带有256位密钥的AES。

如果您使用 Oracle Java 使用128位以上的任何对称密码（包括AES 256），您必须下载并安装JCE Unlimited Strength 管辖区域政策文件你的版本。对于当前支持的版本8，在通用下载页面http://www.oracle.com/technetwork/java/javase/downloads/index.html底部附近，它会链接到http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html。对于旧版本，搜索会找到http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html和http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html。

PS：SSLHandshakeException while connecting to a https site的欺骗，虽然我不确定你是否可以找到它。

获取请求handshake_faliure：javax.net.ssl.SSLHandshakeException
