Question

我尝试通过Admin HTTP API部署包含节点属性中凭据的流。在我的情况下，它是类型为mqtt-broker的节点。安全标签包含一个属性user，我尝试将其放入API调用中。

此属性存储在flows_<hostname>_cred.json中。就像this post所说的那样，该文件可能是encrypted。在我的案例中，settings.js设置为credentialSecret: false。

是否可以在Admin HTTP API中传递存储在flows_<hostname>_cred.json中的值？还是在本地替换文件的唯一方法？

修改

我发送到https://127.0.0.1:1880/flows的测试流返回HTTP代码204。

如果我在"user": "TEST"中添加e8482c08.9858f，这对我不起作用。

您不会直接将数据传递到creds文件，运行时会为您处理。

您需要将creds属性添加到流程中的匹配节点，然后发布到admin api。然后将它们剥离，加密并添加到creds文件中。

因此，对于mqtt-broker配置节点，您可以在名为凭据的字段中添加user和password字段。如此处https://nodered.org/docs/creating-nodes/credentials
