Golang Playwright Chrome配置详解

最近在学习用Golang结合Playwright控制Chrome浏览器，但在配置过程中遇到了一些问题。想请教各位：

  1. 如何正确安装Playwright的Golang绑定？需要单独安装浏览器驱动吗？
  2. Chrome的启动参数应该在哪里配置？比如想设置无头模式和禁用沙箱该怎么写？
  3. 代码中如何指定Chrome的二进制路径？不同操作系统下路径写法有区别吗？
  4. 调试时出现浏览器启动失败或超时错误，一般可能是什么原因导致的？
    有没有完整的配置示例可以参考？谢谢！

Golang Playwright 配置 Chrome 主要分这几步：

  1. 安装依赖
go mod init your-project
go get github.com/playwright-community/playwright-go
npx playwright install chrome
  1. 基础配置示例
package main

import (
    "github.com/playwright-community/playwright-go"
)

func main() {
    pw, _ := playwright.Run()
    
    browser, _ := pw.Chromium.Launch(playwright.BrowserTypeLaunchOptions{
        Headless: playwright.Bool(false),  // 显示浏览器
        Channel:  playwright.String("chrome"),
    })
    
    page, _ := browser.NewPage()
    page.Goto("https://example.com")
    
    // 等待页面加载
    page.WaitForLoadState("networkidle")
    
    browser.Close()
    pw.Stop()
}
  1. 常用配置选项
  • Headless: 是否无头模式
  • Args: 启动参数，如 []string{"--disable-web-security"}
  • ExecutablePath: 指定 Chrome 路径
  • Viewport: 设置窗口大小
  • IgnoreHTTPSErrors: 忽略 HTTPS 错误
  1. 实用技巧
  • 设置用户数据目录保持登录状态
  • 使用 --no-sandbox 参数解决 Linux 环境问题
  • 通过 page.SetViewportSize() 动态调整窗口大小

注意：首次运行会自动下载浏览器，确保网络通畅。

Golang Playwright Chrome 配置详解

Playwright 是一个强大的浏览器自动化工具，Go 语言版本提供了对 Chrome 浏览器的完整支持。

基础配置

package main

import (
    "context"
    "log"

    "github.com/playwright-community/playwright-go"
)

func main() {
    pw, err := playwright.Run()
    if err != nil {
        log.Fatalf("启动 Playwright 失败: %v", err)
    }
    defer pw.Stop()

    // Chrome 浏览器配置
    browser, err := pw.Chromium.Launch(playwright.BrowserTypeLaunchOptions{
        Headless: playwright.Bool(false),     // 是否无头模式
        Channel:  playwright.String("chrome"), // 使用系统 Chrome
        Args: []string{
            "--no-sandbox",
            "--disable-dev-shm-usage",
            "--disable-web-security",
        },
    })
    if err != nil {
        log.Fatalf("启动 Chrome 失败: %v", err)
    }
    defer browser.Close()
}

常用配置选项

1. 浏览器启动选项

launchOptions := playwright.BrowserTypeLaunchOptions{
    Headless: playwright.Bool(true),           // 无头模式
    SlowMo:   playwright.Float(100),           // 操作延迟(毫秒)
    Timeout:  playwright.Float(30000),         // 启动超时时间
    Devtools: playwright.Bool(true),           // 开启开发者工具
}

2. 浏览器上下文配置

context, err := browser.NewContext(playwright.BrowserNewContextOptions{
    Viewport: &playwright.Size{
        Width:  1920,
        Height: 1080,
    },
    UserAgent: playwright.String("自定义 User Agent"),
    IgnoreHTTPSErrors: playwright.Bool(true),
    JavaScriptEnabled: playwright.Bool(true),
})

3. 页面配置

page, err := context.NewPage()
if err != nil {
    log.Fatalf("创建页面失败: %v", err)
}

// 设置页面超时
page.SetDefaultTimeout(30000)
page.SetDefaultNavigationTimeout(60000)

高级配置示例

func configureAdvancedChrome() {
    pw, _ := playwright.Run()
    
    browser, _ := pw.Chromium.Launch(playwright.BrowserTypeLaunchOptions{
        Headless: playwright.Bool(false),
        Args: []string{
            "--start-maximized",
            "--disable-blink-features=AutomationControlled", // 隐藏自动化特征
            "--disable-extensions",
            "--disable-plugins",
            "--disable-background-timer-throttling",
            "--disable-backgrounding-occluded-windows",
            "--disable-renderer-backgrounding",
        },
        ExecutablePath: playwright.String("/path/to/chrome"), // 自定义 Chrome 路径
    })

    context, _ := browser.NewContext(playwright.BrowserNewContextOptions{
        Viewport: nil, // 使用默认视口大小
        ExtraHTTPHeaders: map[string]string{
            "Accept-Language": "zh-CN,zh;q=0.9",
        },
    })
    
    defer browser.Close()
}

代理配置

browser, err := pw.Chromium.Launch(playwright.BrowserTypeLaunchOptions{
    Proxy: &playwright.Proxy{
        Server: "http://proxy.example.com:8080",
    },
})

环境变量配置

可以通过环境变量设置 Playwright：

PLAYWRIGHT_CHROME_CHANNEL=chrome
PLAYWRIGHT_HEADLESS=true

这些配置可以帮助你更好地控制 Chrome 浏览器的行为，满足不同的自动化测试需求。
