如何解决无法使用react-native-xmpp连接到Ejabberd Server
我正在尝试使用react-native-xmpp和Ejabberd创建一个基本的聊天应用程序，但是出现证书错误。这是完整的控制台输出：
Pressed
[Fri Aug 21 2020 04:40:01.140] LOG react-native-xmpp: Message: "Testing..." being sent to user: user@ec2-3-14-27-95.us-east-2.compute.amazonaws.com
[Fri Aug 21 2020 04:40:01.360] LOG react-native-xmpp: Error: java.security.cert.CertificateException: Hostname verification of certificate failed. Certificate does not authenticate ec2-3-14-27-95.us-east-2.compute.amazonaws.com
[Fri Aug 21 2020 04:40:01.366] LOG react-native-xmpp: Disconnected,error: Hostname verification of certificate failed. Certificate does not authenticate ec2-3-14-27-95.us-east-2.compute.amazonaws.com
我可以顺利登录Ejabberd Web管理面板，服务器启动也没有问题，但是似乎不喜欢接受XMPP连接。这是我的客户代码：
var XMPP = require('react-native-xmpp');
class App extends Component {
test() {
console.log('Pressed');
var user = 'admin@ec2-3-14-27-95.us-east-2.compute.amazonaws.com';
var password = 'password';
var to = 'user@ec2-3-14-27-95.us-east-2.compute.amazonaws.com';
XMPP.trustHosts(['ec2-3-14-27-95.us-east-2.compute.amazonaws.com']);
XMPP.connect(user,password);
XMPP.message('Testing...',to);
}
render() {
return (
<View style={styles.center}>
<Button title="Button" onPress={this.test} />
</View>
);
}
}
代码很丑陋，但是现在我只想确保我可以建立和维护连接。

解决方法
我可以登录Ejabberd Web管理面板没问题
使用HTTP还是HTTPS？检查您的网络浏览器是否报告有关证书的任何问题或疑问。
但它似乎不喜欢接受XMPP连接。
好吧，在我的理解中，您的客户端似乎拒绝了ejabberd提供的证书，因为该证书的声明主机与它所服务的主机不匹配。
您可以尝试使用知名的Jabber / XMPP客户端（例如Gajim或Psi）登录。也许这些测试使您对问题有了更多了解。
,您仍在使用ejabberd安装程序提供的示例证书。它是自签名的，没有任何有效性，因此应该会出现错误消息。
如果您希望该错误消失，请不要使用加密，或者更好的方法是：获取由证书颁发机构签名的证书。
