segment-io - 如何访问 segment.io 跟踪/页面调用的 messageID？

Question

发送请求时如何访问段页面事件的messageID？

以下事件生成页面事件：

analytics.page("Home");

网络请求如下所示：

{timestamp: "2021-03-23T17:16:04.699Z",…}
 anonymousId: "12f80ff1-d78e-4d9a-a950-cfb051e8f4ed"
 category: ""
 context: {page: {path: "/", referrer: "", search: "", title: "",…},…}  
 integrations: {}
 messageId: "ajs-de98fbd7a71de273dfbc02f342ee9f5e"
 name: ""
 properties: {}
 sentAt: "2021-03-23T17:16:04.702Z"
 timestamp: "2021-03-23T17:16:04.699Z"
 type: "page"
 userId: "12091906-01011992"
 writeKey: "oQrIdeZq3zOxttwxMGmqqgvZLKXplhtW"
 _metadata: {bundled: ["Segment.io"], unbundled: [], bundledIds: []}

尝试访问请求有效负载的 messageID 部分，我得到：

 messageId: "ajs-de98fbd7a71de273dfbc02f342ee9f5e"
