Java 我得到一个；证书中的主机名没有'；“t匹配”；尝试连接到我的Android应用程序中的助手网站时出错

下午好，正如标题中所说，我无法在我的Android应用程序中连接到我的caddy网站上的子域。我正在将该应用程序的后端从Heroku迁移到我自己的digitalocean droplet，并且该应用程序在使用Heroku时可以正常工作

我得到的错误消息如下：

W/System.err: javax.net.ssl.SSLException: hostname in certificate didn't match: <sub.domain.com> != <domain.com> OR <domain.com>

我可以在我的web浏览器中连接到子域，所以我真的不知道为什么会发生这种情况。我并不太热衷于禁用主机名验证，所以我想知道是否有办法在Caddy端修复它。

因此，我可以通过切换到okhttp库来解决这个问题

渐变依赖项：

dependencies {
    compile group: 'com.squareup.okhttp3', name: 'logging-interceptor', version: '3.8.0'
    compile 'com.squareup.okhttp3:okhttp:3.8.0'
}

课程的新版本：

试试看，您可能会得到更多帮助。您可以在浏览器中连接到domain.com吗？这一行中

url

的值是多少

final-HttpPostHC4 post=new-HttpPostHC4（url）@Tobyalen嘿，我可以连接到domain.com，在我的浏览器中没有问题。然而，我最终通过使用okhttp库解决了这个问题。对不起，浪费了你的时间。也许可以用你所做的回答你自己的问题（如使用不同的图书馆）@TobyAllen好主意，我刚刚回答了。
