代码示例

YAML

main:
  params: [input]
  steps:
    - init:
        assign:
          - userProfile: {}
          - recentItems: []
    - enrichUserData:
        parallel:
          shared: [userProfile, recentItems]  # userProfile and recentItems are shared to make them writable in the branches
          branches:
            - getUserProfileBranch:
                steps:
                  - getUserProfile:
                      call: http.get
                      args:
                        url: '${"https://example.com/users/" + input.userId}'
                      result: userProfile
            - getRecentItemsBranch:
                steps:
                  - getRecentItems:
                      try:

                      except:
                        as: e
                        steps:
                          - ignoreError:
                              assign:  # continue with an empty list if this call fails
                                - recentItems: []
