如果它们没有任何值,如何从板上获取所有 customFieldItems?

How to get all customFieldItems from a board if they don't have any values?

保持简短:

此调用:https://api.trello.com/1/boards/<id>/cards/?fields=all&customFieldItems=true(因为 key/token

将 return 所有卡片,每个卡片都有 属性 "customFieldItems": [],但如果卡片自定义字段项具有设置值,则该值仅包含数据。

那么如何获得为特定板配置的所有 customFieldItems?

自定义字段是针对看板定义的,因此您需要查询看板端点,例如:

curl https://api.trello.com/1/boards/${BOARD_ID}/customFields?key=${TRELLO_API_KEY}&token=${TRELLO_TOKEN}

这将 return 一个 JSON 对象数组,对应于您定义的每个自定义字段(不仅仅是在特定卡片上设置的自定义字段),例如:

[

    "id": "8c6a9274db4ac31ba3cbd81d",
    "idModel": "560bf4298b3dda300c18d09c",

    "display": {
      "cardFront": true
    },
    "name": "Points",

    "options": [

        "idCustomField": "8c6a9274db4ac31ba3cbd81d",
        "value": {
          "text": "1"
        },
        "color": "none",
        "pos": 20480
      },
      {
        "id": "5b6a9274db4ac31ba3cbd820",
        "idCustomField": "8c6a9274db4ac31ba3cbd81d",
        "value": {
          "text": "2"
        },
        "color": "none",
        "pos": 36864
      },
    ],
    "type": "list"
  },
]
