HiveMQ中的Websockets不工作-日志中没有

Question

问题得到解决:查看的底部

我不能连接到websockets。1883年港口运转良好。这是MQTT.fx的输出：

我对服务器和端口进行了Telnet测试，得到了一个空白终端。我猜这意味着有一个连接，因为否则我会有一个“连接失败”。消息日志插件没有显示任何内容，日志文件中也没有显示任何内容。

它的Debian和HiveMQ 3.2.2。

编辑

好的，这是一个Nginx问题，因为没有SSL，我的JavaScript站点就能工作。应该可以将SSL用于http，而对websockets则不安全，正如我在这里看到的：

Nginx MQTT websocket代理1

Nginx MQTT websocket代理2

我试过那里的配置，但没有成功。

解决方案：--不需要带有HiveMQ的Nginx代理。问题是Firefox不接受websockets的自签名证书。将"network.websocket.allowInsecureFromHTTPS“设置为true将使其工作。在Chrome中，您会收到关于JavaScript安全性的消息，您可以接受它。因为我只使用Firefox，而且没有消息，所以花了几个小时才找出了问题所在。此外，泛美卫生组织的onFailure函数也没有出现。

不幸的是，websocket支持尚未实现到MQTT.fx中。

如果您坚持通过websocket连接，您将不得不使用不同的MQTT-客户端。
