这两个xml请求有何不同？
[英]How are these two xml requests different?
问题描述
I found a piece of code recently to help me get live prices into Google Sheets and wanted to expand upon it: 
我最近发现了一段代码，以帮助我将实时价格纳入Google表格，并希望对其进行扩展：
=min(importxml("http://shop.tcgplayer.com/productcatalog/product/show?IsProductNameExact=true&ProductName="&A5, "//div[contains(@class, 'scCardContent')]/span[@*] | //div[contains(@class, 'priceGuidePricePointDiv')][1]//tr[2]/td[contains(@class, 'priceGuidePricePointData')][1]"))
However, when I wrote an xml request in the script editor I was not able to make a successful request. 但是，当我在脚本编辑器中编写xml请求时，我无法成功发出请求。
var xml = UrlFetchApp.fetch(tcgUrl).getContentText();
I tried several different ways but kept getting blocked(?) by Incapsula. 我尝试了几种不同的方式但是被Incapsula阻止了（？）。
<html style="height:100%"><head><META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"><meta name="format-detection" content="telephone=no"><meta name="viewport" content="initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"></head><body style="margin:0px;height:100%"><iframe src="/_Incapsula_Resource?CWUDNSAI=9&xinfo=5-85037313-0 0NNN RT(1489553959732 1) q(0 -1 -1 -1) r(0 -1) B12(4,315,0) U18&incident_id=490000360254449935-589713359258649157&edet=12&cinfo=04000000" frameborder=0 width="100%" height="100%" marginheight="0px" marginwidth="0px">Request unsuccessful. Incapsula incident ID: 490000360254449935-589713359258649157</iframe></body></html>
Am I doing something wrong? 难道我做错了什么？ Is there a way around this? 有没有解决的办法？

You should look to leverage their API instead of scraping the site directly, as that is the preferred way to access pricing data. 您应该利用他们的API而不是直接抓取网站，因为这是访问定价数据的首选方式。
