我正在尝试使用 Hubot 脚本解析 JIRA webhook。

目前，我只有一个非常简单的 Hubot 脚本来打印发布的正文：

module.exports = (robot) ->
  robot.router.post '/jirawebhooks/foo-tickets', (req, res) ->
    console.dir("#{new Date()} jira webhook post_received")
    console.dir(req.body)
    console.dir(req.body.payload)
    console.dir(JSON.parse req.body)

    res.send 'OK'

打印出正文似乎有效 - 除了某些字段（例如问题、字段、报告者被打印为[Object]：

'Wed Oct 01 2014 11:35:36 GMT+0000 (UTC) jira webhook post_received'

我不完全确定为什么？

有效载荷未定义。

在 req.body 上使用 JSON.parse 似乎给了我一个Unexpected token o：

这是因为身体已经以某种方式被解析了吗？如果是这样，是什么解析的？如果它已经被解析，为什么有些字段仍然显示为[Object]？

根据您的堆栈跟踪 bodyParser 正在运行。这意味着如果交付 JSON 数据，它将在到达您之前自动解析。

这意味着 req.body 已经是您解码的 JS 对象，因此您不必再次解析它。

某些字段被标记为 [Object] 的原因是自动转储不会一直深入到结构中。在它决定停止的地方，它会显示 [Object] 而不是更深的结构。您可以使用 JSON.stringify 将其全部转储...您可以在此处查看 Jira 发送的 webhook 结构。
