Question

一段时间后返回 Android。我刚刚购买了 EV 证书，并尝试使用 SSL/TSL 连接到我的 Web 服务。我得到：

我在此处的其中一个答案中发现我应该尝试 testssl.sh。我安装了它，这是一些报告...

让我知道查看更多内容是否有用...

我查看了服务器（在 AWS 上托管的 nginx），在此期间日志中没有错误。

这里是 SSL 上下文的创建：

    try {
        sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, new java.security.SecureRandom());
    } catch (NoSuchAlgorithmException | KeyManagementException ex) {
        Log.e(TAG, "Error creating SSL context", ex);
    }

TSLv1.3 因不受支持而失败。

这是我的连接代码：

    try {
        URL url = new URL(urlName);
        HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
        urlConnection.setSSLSocketFactory(sslContext.getSocketFactory());
        urlConnection.setDoOutput(true);
        urlConnection.setFixedLengthStreamingMode(bytesToSend.length);

        OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream()); //Exception here
        out.write(bytesToSend);
        out.flush();

        InputStream in = new BufferedInputStream(urlConnection.getInputStream());
        result = readStreamAsString(in);
    }
   catch(Exception exception) {
        Log.e(TAG, "Error registering site", exception);
        throw new Square1Exception("Error hitting:" + urlName, exception);
    }

如输出流创建所示那样爆炸。

我的平板电脑运行的是 Android 9，这比我发现的大多数类似问题都要新。

感谢所有建议。

正如 Joy 和 alexrait 所建议的，问题不在于指定 SSL 上下文。显然，默认情况下，android 不会尝试最好的。 :(

所以，我在这里添加了代码：

    try {
        sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, new java.security.SecureRandom());
    } catch (NoSuchAlgorithmException | KeyManagementException ex) {
        Log.e(TAG, "Error creating SSL context", ex);
    }

然后添加这一行来使用它：

        HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
        urlConnection.setSSLSocketFactory(sslContext.getSocketFactory());

现在似乎一切正常。感谢您的帮助。
