修订:请注意,我现在正在使用IP地址10.0.0.15,发布到MQTT代理的设备是10.0.0.122。这仍然可以通过终端进行。
我认为我正在使用MQTT连接器。遇到以下帖子中所述的问题后,我已经前进了
Can't connect to localhost Mosquitto Broker with Javascript?
我现在看到以下错误。
mqttws31.js:1585 Uncaught Error: AMQJS0013E Invalid argument
169.254.118.199 for host.
at new M (mqttws31.js:1585)
at startConnect (n.js:29)
at HTMLInputElement.onclick ((index):107)
根据js文件,它指示匹配错误。我尝试将IP地址添加为wss://169.254.118.199,但这不能解决问题。你知道是什么原因造成的吗?
我尝试了以下
wss://169.254.118.199
ws://169.254.118.199
wss://localhost
tcp://169.254.118.199
tcp://localhost
它们都产生相同的错误
这是错误指向mqttws31.js中的代码。
if (arguments.length == 2) {
// host: must be full ws:// uri
// port: clientId
clientId = port;
uri = host;
var match = uri.match(/^(wss?):\/\/((\[(.+)\])|([^\/]+?))(:(\d+))?
(\/.*)$/);
if (match) {
host = match[4]||match[2];
port = parseInt(match[7]);
path = match[8];
} else {
--> this is where error is pointing throw new Error(format(ERROR.INVALID_ARGUMENT,[host,"host"]));
}
} else {
if (arguments.length == 3) {
clientId = path;
path = "/mqtt";
}
if (typeof port !== "number" || port < 0)
throw new Error(format(ERROR.INVALID_TYPE, [typeof port, "port"]));
if (typeof path !== "string")
throw new Error(format(ERROR.INVALID_TYPE, [typeof path, "path"]));
var ipv6AddSBracket = (host.indexOf(":") != -1 && host.slice(0,1) != "[" &&
host.slice(-1) != "]");
uri = "ws://"+(ipv6AddSBracket?"["+host+"]":host)+":"+port+path;
}
编辑:在打印输出中,我在网页上看到以下内容已发送给Paho客户:
Connecting to: 10.0.0.122 on port: 8083
Using the following client value: clientID-64
我希望能够成功连接IP地址并获取MQTT有效载荷
答案 0 :(得分:0)
要获取所看到的错误,您不能使用在其他问题中发布的代码:
clientID = "clientID-" + parseInt(Math.random() * 100);
// Fetch the hostname/IP address and port number from the form
host = document.getElementById("host").value;
port = document.getElementById("port").value;
// Print output for the user in the messages div
// Initialize new Paho client connection
client = new Paho.MQTT.Client(host, Number(port), clientID);
仅当您仅将两个参数传递给Paho.MQTT.Client()
构造函数而不是3时,才会发生该错误。在这种情况下,第一个参数被解释为完整的URI(例如ws://10.0.0.122:8083/mqtt
),第二个参数被解释为完整的URI。客户ID。
