家中多个摄像机用于人体识别。把这个步骤做成了一个子流程。
但是多个摄像机如何选择呢?
配置基本一样。就是IP不同

var ip = `10.0.0.222`;
msg.url = `http://${ip}:11110/picture/1/current/`;
return msg;


改ip变量就行了吧

使用这个方法后。提示
"Warning: msg properties can no longer override set node properties. See bit.ly/nr-override-msg-props"

非常感谢。已经搞定了。可能是之前的http request是其他流程导入的关系。不起作用。重新拉了个http request就ok了。。
