【问题描述】：
有人可以告诉我如何在 Android 中解决 SSLHandshakeException 问题吗？
请参阅下面的错误，我一直在尝试使用 HttpURLConnection 对象访问这个 URL。

请看下面我方法的代码
public static String getResponseFromHttpUrl(URL url) throws IOException {
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
InputStream in = urlConnection.getInputStream();
Scanner scanner = new Scanner(in);
scanner.useDelimiter("\\A");
boolean hasInput = scanner.hasNext();
if (hasInput) {
return scanner.next();
} else {
return null;
}
} finally {
urlConnection.disconnect();
}
}
【问题讨论】：
-
服务器有问题。由于您尚未发布您使用的 URL，我们无法帮助您解决此问题。
-
如果在运行 Android 9 或更高版本的手机中遇到此问题，并且您的 URL 以 http:// 而不是 https:// 开头，尝试在您的 manifest.xml
android:usesCleartextTraffic="true". 中添加这一行 -
TLSV1_ALERT_PROTOCOL_VERSION：这才是真正的原因。在这种情况下，这可能意味着服务器不喜欢客户端提供的 TLS 版本。可能服务器需要 TLS 1.2，而设备太旧，无法支持。 -
根据SSL Server Test，此服务器仅支持TLS 1.3。
