用rod获取百度搜索结果的例子

package main

import (
    "fmt"
    "time"

    "github.com/ysmood/rod"
    "github.com/ysmood/rod/lib/input"
    "github.com/ysmood/rod/lib/launcher"
)

func Example_reuse_sessions() {
    url := launcher.NewUserMode().Launch()

    browser := rod.New().ControlURL(url).Connect()

    page := browser.Timeout(time.Second * 15).Page("https://www.baidu.com")
    page.Window(0, 0, 1920, 1080)
    // use css selector to get the search input element and input "git"
    page.Element("#kw").Input("测试").Press(input.Enter)
    // wait until css selector get the element then get the text content of it
    text := page.Element(`#31  > div.c-abstract`).Text() //这里的选择器selector是从chrome控制台中copy的。

    fmt.Println(text)

    fmt.Println("done")

    // Skip
    // Output: done
}
func main() {

    Example_reuse_sessions()
    for {
    }

}

比较简洁、直观。

 补充：用带iframe及alert的那个内网站点测试一下，果然很爽 

package main

import (
    "fmt"
    "time"

    "github.com/ysmood/rod"
    "github.com/ysmood/rod/lib/input"
    "github.com/ysmood/rod/lib/launcher"
)

func Example_reuse_sessions() {
    //page.WindowMaximize()
    //获取地址栏url看看
    url := launcher.NewUserMode().Launch()
    browser := rod.New().ControlURL(url).Connect()
    for _, p := range browser.Pages() {
        uri := p.Eval(`() => window.location.href`).String()
        fmt.Println(uri)
    }
    page := browser.Pages()[0]
    page.Navigate("http://192.168.132.XX/login/Login.jsp?logintype=1")
    page.WaitIdle() 
    page.Element("#loginid").Input("admin")
    page.Element("#userpassword").Input("1234").Press(input.Enter)
    //page.Element("#login").Click()
    page.WaitIdle() //这里不能用time.sleep延时
    //再次获取地址栏url看看
    for _, p := range browser.Pages() {
        uri := p.Eval(`() => window.location.href`).String()
        fmt.Println(uri)
    }
    fmt.Println(page.Element("#_ButtonOK_0").Text())
    page.Element("#_ButtonCancel_0").Click()
    //正式开始作业，处理iframe
    for i := 0; i < 5; i++ {
        Do()
    }

}

func Do() {
    //page.WindowMaximize()
    //获取地址栏url看看
    url := launcher.NewUserMode().Launch()
    browser := rod.New().ControlURL(url).Connect()
    for _, p := range browser.Pages() {
        uri := p.Eval(`() => window.location.href`).String()
        fmt.Println(uri)
    }
    page := browser.Pages()[0]
    page.Navigate("http://192.168.132.80/wui/main.jsp?templateId=3")
    page.WaitIdle() //正式开始作业，处理iframe
    frame01 := page.Timeout(6 * time.Second).Element("[name=mainFrame]").Frame()
    fmt.Println(frame01.Element("#_contenttable_655 > tbody > tr > td:nth-child(2) > table > tbody > tr:nth-child(1) > td:nth-child(2) > a > font > font > span").Text())
    frame01.Element("#_contenttable_655 > tbody > tr > td:nth-child(2) > table > tbody > tr:nth-child(1) > td:nth-child(2) > a > font > font > span").Click()
    page.WaitIdle() //点击后会弹出新窗口，所以这句或许应改成page.WaitPage()
    page = browser.Pages()[0]
    frame01 = page.Element("[name=bodyiframe]").Frame()
    frame01.WaitIdle()
    fmt.Println(frame01.Element("#flowbody > table > tbody > tr > td > form > div:nth-child(23) > font").Text())
    fmt.Println("here")
    frame02 := frame01.Element("#cke_contents_remark > iframe").Frame()
    frame02.WaitIdle()
    fmt.Println(frame02.Element("body").Text())
    //frame02.Element("body").Click().Input("已审批").Press(input.Enter)
    frame02.Element("body").Click().Input("已审批") //可以不加Click()
    page.Element("#toolbarmenu > td:nth-child(1) > table > tbody > tr:nth-child(2) > td.x-btn-mc > em > button").Click()
    page.HandleDialog(true, "") //之前不知道用这句，向页面body直接.Press(input.Enter)竟然也可以关掉alert
    page.Close()                //也许应加上go关键词，但代码能用就行了。

    fmt.Println("done")
}

func main() {

    Example_reuse_sessions()

}

 上面是初学时写的例子，实际运行中不太可靠。后来修改为类似下面的例子。在学习过程中还得到了ysmood本人的热心帮助，深表感谢！

package main

import (
    "fmt"
    "time"

    "github.com/ysmood/rod"
    "github.com/ysmood/rod/lib/input"
    "github.com/ysmood/rod/lib/launcher"
    "github.com/ysmood/rod/lib/proto"
)

// Shows how to subscribe events.
//var e9 = &proto.PageLoadEventFired{}
//var backoff = kit.BackoffSleeper(1*time.Second, 8*time.Second, nil)

func main() {
    url := launcher.New().
        Headless(false). // run chrome on foreground, you can also use env "rod=show"
        //Delete("enable-automation"). //可以让chrome不显示那句"chrome正受到自动测试软件的控制"。
        Devtools(false). // open devtools for each new tab
        Launch()
    browser := rod.New().
        ControlURL(url).
        Slowmotion(300 * time.Millisecond). // each input action will take 2 second
        Connect().
        Timeout(30 * time.Second)
    //defer browser.Close()
    page01 := browser.Pages()[0]
    proto.PageAddScriptToEvaluateOnNewDocument{
        Source: `Object.defineProperties(navigator, {webdriver: {get: () => undefined}})`, //修改window.navigator.webdriver的值
    }.Call(page01)
    //page01.Eval(`() => Object.defineProperties(navigator, {webdriver: {get: () => undefined}})`) //这句应该是晚了
