ssl - HiveMQ 中的 Websockets 不工作 - 日志中没有任何内容

Question

问题已解决:检查帖子底部

我无法连接到 websockets。端口 1883 工作正常。这是 MQTT.fx 的输出:

我对服务器和端口进行了 Telnet 测试，得到一个空白终端。我想这意味着有一个连接，否则我会有一个“连接失败”。消息日志插件不显示任何内容，日志文件中也没有任何内容。

它的 Debian 和 HiveMQ 3.2.2。

好的，这是一个 Nginx 问题，因为没有 SSL，我的 JavaScript 网站可以正常工作。正如我在这里看到的那样，应该可以对 http 使用 SSL 而对 websockets 不安全:

Nginx MQTT websocket proxy 1

Nginx MQTT websocket proxy 2

我试过那里的配置，但没有成功。

解决方案:HiveMQ 不需要 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，您会收到有关 JavaScript 安全性的消息，您可以接受它。因为我只使用 Firefox 并且没有消息，所以花了几个小时才找出问题所在。 paho onFailure 函数也没有出现。

Answer 1

不幸的是websocket support尚未在 MQTT.fx 中实现。

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

干杯，
