@wushengyeyouya 大佬，帮忙解决下这个问题

[specialbiscuit]

能知道怎么调用就行

[specialbiscuit]

目前我的调用方式需要调用到5个服务：请求发起 -> /tokenQuery (没有拿到token) -> /execute/query_user(我的服务path, token直接数据库取得) -> /93/get (获取任务状态, status为Suucess就继续下一步) -> /getDirFileTrees(获取到path路径，为下一步提供入参) -> /openFile (获取结果) -> 请求结束。 不知道是不是这样，如果是这样，感觉调用一个服务要走这么多接口吗，还是说我理解错了，求大佬帮助

楼上的 /execute/query_user操作，会经常性的返回status为Failed的结果，我对比了DSS后台的查询方式，看到了/get请求要反复查询的，这个对于外部系统没法这样调用，请问有别的调用方式吗

Data service token from/queryById? Interface returns (page clicks into use), field is userToken. Access to all interfaces is GateWay certified. The token of a data service can only be used for the management process of a data service. Authentication using postman requires either cookies on the page or secret key authentication using linkis-gateway. Add Token-Code: XXX to the headThis specifies the login key for linkis-gateway Token-User: XXX This specifies the login user for linkis-gateway.

I did it according to this step, and also called execute/{path:*}, but in the step of {id}/get, the status returned was FAILED

/openFile

If I want to get the result set, do I have to call 5 interfaces, namely /tokenQuery, /execute/{path:*}, /{id}/get, /getDirFileTrees and /openFile, is this calling method correct?
