您可以从 editmeta REST资源.

You can get that information either from the createmeta or editmeta REST resources.

如果要在编辑特定问题时检索可用选项，请使用editmeta.例如.

Use editmeta if you want to retrieve the available options when editing a specific issue. E.g.

GET /rest/api/2/issue/TEST-123/editmeta

当您要结合问题类型检索项目的选项时，请使用createmeta.例如

Use createmeta when you want to retrieve the options for a project in combination with an issue type. E.g.

GET /rest/api/2/issue/createmeta?projectKeys=MYPROJ&issuetypeNames=Bug&expand=projects.issuetypes.fields

带有选项的customfields将返回如下:

The customfields with options will be returned like this:

"customfield_12345": {
  "schema": {
    "type": "string",
    "custom": "com.atlassian.jira.plugin.system.customfieldtypes:select",
    "customId": 12345
  },
  "name": "MySelectList",
  "allowedValues": [
    {
      "self": "http://jira.url/rest/api/2/customFieldOption/14387",
      "value": "Green",
      "id": "14387"
    },
    {
      "self": "http://jira.url/rest/api/2/customFieldOption/14384",
      "value": "Blue",
      "id": "14384"
    }
  ]
}
