面试题求解，做过 ad tracking 或者 chrome dev tool 玩的溜的请进

[halden]

Using Chrome ’ s Developer Tools or Firefox ’ s HttpFox plugin, please look at the network calls when you click on the following two creatives. The MediaMath click tracker is working correctly if you see a call beginning with http://pixel.mathtag.com/click

Creative #1: https://creative-preview.mathads.com/p/bjQnKwgb

Creative #2: https://creative-preview.mathads.com/s/mWdP6keN

Is the click tracker firing on both ads? If not, examine the tag code of both creatives to identify where the problem might lie. Explain your findings.

以上是某家公司的面试题，然后根据我的分析，并没有从 http request 里面找到直接访问 http://pixel.mathtag.com/click 的请求，但是通过分析 timeline 他在跑 js 的时候通过跳转的网址中包涵了下面的内容 {"pid":7199,"tid":1295,"ts":227361902822,"ph":"X","cat":"v8,devtools.timeline","name":"v8.compile","args":{"fileName":"https://bs.serving-sys.com/BurstingPipe/adServer.bs? cn=brd&Page=&PluID=0&Pos=32223305210475495&EyeblasterID=35067080&clk=0&sct=1&dg=8504866&dgo=5079662&rtu=http://www.mediamath.com&di=0&pc=&sessionid=7774604282335317787&usercookie=u2=113fb65d-0e98-4537-88f3-67f41aeeb180&OptOut=0&ncu=http://pixel.mathtag.com/click/img%253Fmt_aid%253D0%2526mt_id%253D0%2526mt_adid%253D0%2526mt_sid%253D0%2526mt_exid%253D0%2526mt_inapp%253D0%2526redirect%253D&ebReferrer=https://creative-preview.mathads.com/s/mWdP6keN","data": {"columnNumber":154,"lineNumber":1,"url":"https://bs.serving-sys.com/BurstingPipe/adServer.bs? cn=brd&Page=&PluID=0&Pos=32223305210475495&EyeblasterID=35067080&clk=0&sct=1&dg=8504866&dgo=5079662&rtu=http://www.mediamath.com&di=0&pc=&sessionid=7774604282335317787&usercookie=u2=113fb65d-0e98-4537-88f3-67f41aeeb180&OptOut=0&ncu=http://pixel.mathtag.com/click/img%253Fmt_aid%253D0%2526mt_id%253D0%2526mt_adid%253D0%2526mt_sid%253D0%2526mt_exid%253D0%2526mt_inapp%253D0%2526redirect%253D&ebReferrer=https://creative-preview.mathads.com/s/mWdP6keN"}},"dur":298,"tdur":293,"tts":11647079},

所以我不确定这算不算是访问了 http://pixel.mathtag.com/click ，还有这道题究竟应该怎么解

我是你同行.
1. be aware, 你把他们这处 trackingpixel 放出来,他们可能 会知道有 V2EX 上人看过这个,就等于你泄露的面试题
2. 我没点你链接,你点开 creative 后,如果有 click 在 timeline,那就是 click tracker fire 了,这看看 timeline 就知道了,很简单,根据你帖的,click tracker fire 了,他完全可以 capture 这个

@20150517 啊。。我今天才看到你的回复，这个是我朋友问我的，我做前端的，对广告部署不太了解。。然后我想既然他都这样问了，而且他给了我完整的面试题的 pdf ，我也就想试试自己能不能做出来

然后我并有在 timeline 里面找到"直接访问" http://pixel.mathtag.com/click 的 http request ，而是你看他 link 带的参数中包涵有这个 tracker 的跳转，但有没有真正跳转到我并不知道
