Question

这是我的代码

        URL url = new URL(requestUrl);
        HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
        BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));

我遇到了异常

java.security.cert.CertificateException: No name matching www.sandbox.freelancer.com found

据我所知，这个网站没有适当的证书。但是我必须登录这个网站。任何建议将不胜感激。感谢。

Answer 1

创建不验证证书链的信任管理器

TrustManager[] trustAllCerts = new TrustManager[]{
    new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }
        public void checkClientTrusted(
            java.security.cert.X509Certificate[] certs, String authType) {
        }
        public void checkServerTrusted(
            java.security.cert.X509Certificate[] certs, String authType) {
        }
    }
};

安装所有信任的信任管理器

try {
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
}

现在访问https网址

try {
    URL url = new URL("https://www.sandbox.freelancer.com");
    HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
    BufferedReader br = 
         new BufferedReader(new InputStreamReader(conn.getInputStream()));

} catch (MalformedURLException e) {
}

您可以保存证书（在Firefox中获取），然后将证书添加到密钥库，然后将您的应用配置为使用该密钥库。
