示例1: addRequest
func addRequest(p *page.Page, tag, url, cookie, content string) {
req := request.NewRequest(url, "json", tag, "GET", "", nil, nil, nil, content)
p.AddTargetRequestWithParams(req)
}示例2: Process
// Parse html dom here and record the parse result that we want to Page.
// Package goquery (http://godoc.org/github.com/PuerkitoBio/goquery) is used to parse html.
func (this *MyPageProcesser) Process(p *page.Page) {

// AddTargetRequestWithParams Params:
// 1. Url.
// 2. Responce type is "html" or "json" or "jsonp" or "text".
// 3. The urltag is name for marking url and distinguish different urls in PageProcesser and Pipeline.
// 4. The method is POST or GET.
// 5. The postdata is body string sent to sever.
// 6. The header is header for http request.
// 7. Cookies
// 8. Http redirect function
