Segment.IO请求失败，状态为“已取消”

Question

I've followed the steps here: https://segment.io/libraries/analytics.js without deviating from their instructions.

Here are the headers from one of the requests:

Request URL:http://api2.segment.io/v1/t
Request Headersview source
  Content-Type:text/plain
  Origin:http://staging.mywebsite.com
  Referer:http://staging.mywebsite.com/
  User-Agent:Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.72 Safari/537.36
Request Payloadview source
  {userId:null, sessionId:ccea006ec74cc613, event:Loaded a Page,…}
    apiKey: "eijofijoi4r"
    callbackId: 350
    context: {}
    event: "Loaded a Page"
    properties: {url:http://staging.mywebsite.com/, referrer:,…}
    sessionId: "ccea006ec74cc613"
    userId: null

Both the Preview and the Response have no data available. Other attributes worth mentioning:

Method: POST
Status: (cancelled)
Type: Pending

What are the reasons that could cause a status of (cancelled) ?

Are there any steps I can take to gather more information?

Answer 1

我也看到了这一点-事实证明，AdBlock扩展程序阻止了请求。

Answer 2

It could possibly be due to a deeply nested object inside properties that the API doesn't like. I think we take objects nested up to 7 levels deep last I checked.
