javax.net.ssl.SSLHandshakeException: java.security.cert

问题及处理方法记录

Http请求时候出现这个问题，一般都是请求的Url使用的是Https ，但是安全证书有问题，导致请求失败，根源在证书问题上，这里我们不影响开发的话，可以在代码里面配置，暂时避免这个错误。

1、项目中添加这个类

public class SSLSocketClient {

    // 获取这个SSLSocketFactory
    public static SSLSocketFactory getSSLSocketFactory() {
        try {
            SSLContext sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, getTrustManager(), new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    // 获取TrustManager
    private static TrustManager[] getTrustManager() {
        TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {

                    }

                    @Override
                    public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {

                    }

                    @Override
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return new java.security.cert.X509Certificate[0];
                    }
                }
        };
        return trustAllCerts;
    }

    // 获取HostnameVerifier
    public static HostnameVerifier getHostnameVerifier() {
        HostnameVerifier hostnameVerifier = new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        };
        return hostnameVerifier;
    }
}

2、OkhttpClicent配置

public OkHttpClient.Builder createOkHttpBuilder() {
        OkHttpClient.Builder okHttpBuilder = new OkHttpClient.Builder();
        ...
        // 添加下面两句代码
        okHttpBuilder.sslSocketFactory(SSLSocketClient.getSSLSocketFactory());
        okHttpBuilder.hostnameVerifier(SSLSocketClient.getHostnameVerifier());

        return okHttpBuilder;
    }
