基于HslCommunication.dll的 MQTT客户端测试

mndsoft 9月前 1006

HslCommunication.dll是一个.NET库，支持MQTT功能，根据来自 https://www.chengxu.xyz/t/461 网站的帖子做了个测试，增加了用户名密码验证和界面。

支持连接，订阅等。还有一些慢慢研究。

不知为何在mqttClient.OnMqttMessageReceived 函数里收到数据想 winform.txtLog.appendText( textColor = 0xFF0000,topic ++ '\r\n'; ) 到富文本框里，就会出现闪崩。

只能 log 或 winform.edit.text =topic;

感觉这个库体积比较大，如果单独只需要MQTT的话，还是 MQTTnet 这个专门库好，体积小，功能丰富，接下来研究这个库。

appendtext参数如果要定义文本颜色, 参数必须是个表, winform.richedit.appendText({textColor = 0xFF0000,topic ++ '\r\n';}); 这样就行了

popde appendtext参数如果要定义文本颜色, 参数必须是个表, winform.richedit.appendText({textColor = 0xFF0000,topic ++ '\r\n';}) ...
也可以这样写的。不是这个问题哈 /* 下面这样写也可以，等于传了一个表参数并省略了外层大括号{}。函数会自动展开参数表的数组成员作为其他调用参数，可指定多个文本参数。 */ winform.richedit.appendText( textColor = 0xFF0000, "蓝色文本" ) //下面这样写作用一样 winform.richedit.appendText( { textColor = 0xFF0000, "蓝色文本"} )

是啊，这个HslCommunication.dll 太大了，不过包含了很多功能。如果这个能封住aardio库，基本工控上的功能都可以搞定了

有关闪崩的问题找到了，不要用最新版的HslCommunication.dll，用11.1这个版本的，最近最新版的好像增加的限制次数。
