按照此处的描述和操作 Devops 命令建立与 MQTT 3.1.1 端点的连接最终得到无效的 json 400 响应。甚至MQTT-Bidirectional示例也被 400 拒绝。所以这就是为什么我在这里发布这个问题以获取提示我目前做错了什么以及我可以做些什么来帮助其他人在同一问题上运行。这是我的卷曲请求:
gd@gd:~/ditto/mosquitto$ curl -X POST 'http://{ditto-url}/devops/piggyback/connectivity?timeout=10000' -u devops:foobar -H 'Content-Type: application/json' -d createMQTT_connection.json
{"status":400,"error":"json.invalid","message":"Failed to parse JSON string 'createMQTT_connection.json'!","description":"Check if the JSON was valid (e.g. on https://jsonlint.com) and if it was in required format."}
检查我的 json 文件的提示返回我的 json 是有效的。
这是我的 json 文件当前的样子:
{
"targetActorSelection": "/system/sharding/connection",
"headers": {
"aggregate": false
},
"piggybackCommand": {
"type": "connectivity.commands:createConnection",
"connection": {
"id": "mqtt-example-connection-123",
"name": "mmqtt-example-connection-123",
"connectionType": "mqtt",
"connectionStatus": "open",
"failoverEnabled": true,
"uri": "tcp://{mqtt-broker-url}:1883",
"sources": [
{
"addresses": [
"{ditto-url}/#"
],
"authorizationContext": ["nginx:ditto"],
"qos": 0,
"filters": []
}
],
"targets": [
{
"address": "{ditto-url}/{{ thing:id }}",
"topics": [
"_/_/things/twin/events"
],
"authorizationContext": ["nginx:ditto"],
"qos": 0
}
]
}
}
}
有人知道为什么这个 json 无效?
感谢您提供解决此问题的支持和提示!
[编辑] 首先,“-f”对 curl 请求更有意义:
curl -X POST -u devops:foobar 'http://{ditto-url}:8080/devops/piggyback/connectivity?timeout=10000' -f createMQTT_connection_1.json
curl: (22) The requested URL returned error: 400 Bad Request
curl: (6) Could not resolve host: createMQTT_connection_1.json
第二个这里更新json(结果如上所示)
{
"targetActorSelection": "/system/sharding/connection",
"headers": {
"aggregate": false
},
"piggybackCommand": {
"type": "connectivity.commands:createConnection",
"connection": {
"id": "mqtt-example-connection-123",
"connectionType": "mqtt",
"connectionStatus": "open",
"failoverEnabled": true,
"uri": "tcp://{MQTT-Broker-url}:1883",
"sources": [{
"addresses": ["ditto-tutorial/#"],
"authorizationContext": ["nginx:ditto"],
"qos": 0,
"filters": []
}],
"targets": [{
"address": "ditto-tutorial/{{ thing:id }}",
"topics": [
"_/_/things/twin/events",
"_/_/things/live/messages"
],
"authorizationContext": ["nginx:ditto"],
"qos": 0
}]
}
}
}
