使用 Go Colly 获取属性值
Getting attribute value with Go Colly
在“html”中使用c.OnHTML时,如何获取#id-card-1 ID 中的 href 属性值?
c.OnHTML("html", func(e *colly.HTMLElement) {
...
linkStr := "#id-card-1[href]" //???
log.Print(e.Attr(linkStr))
...}
这是页面中HTML的片段:
<a href="/some-link-here" target="_blank" id="id-card-1" class="card card--featured" data-item-card="11042036">
ChildAttr
函数可用于此目的。
ChildAttr returns the stripped text content of the first matching
element's attribute.

c.OnHTML("html", func(e *colly.HTMLElement) {
linkStr := "#id-card-1"
log.Println(e.ChildAttr(linkStr, "href"))
})
