Node-Red：通过 Admin HTTP API 部署流程，在节点属性中包含凭据

Question

我尝试通过 Admin HTTP API containing credentials in nodes properties. In my case it's a node of type mqtt-broker 部署流程。安全选项卡包含一个属性 user，我试图将其放入 API 调用中。

这个属性存储在flows_<hostname>_cred.json中。喜欢 stated this file could be encrypted。在我的例子中 settings.js 它设置为 credentialSecret: false.

是否可以在 Admin HTTP API 中传递存储在 flows_<hostname>_cred.json 中的值？或者是唯一在本地替换文件的方法？

我发送给https://127.0.0.1:1880/flows的测试流程，returnsHTTP代码204。

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

您不直接将数据传递给 creds 文件，这是由运行时为您处理的。

您需要将 creds 属性添加到流程中的匹配节点，然后 post 到管理员 api。然后它们将被剥离、加密并添加到 creds 文件中。

因此，对于 mqtt-broker 配置节点，您将在名为 credentials 的字段中添加 user 和 password 字段。如文档中所述 https://nodered.org/docs/creating-nodes/credentials
