Golang浏览器能力识别与解析插件库browscap_go的使用

介绍

PHP有一个get_browser()函数可以获取用户浏览器的能力信息。browscap_go是Go语言中类似get_browser()功能的实现。

browscap.ini文件是一个数据库，提供了大量关于浏览器及其能力的详细信息，如名称、版本、JavaScript支持等。

快速开始

首先需要使用browscap.ini文件初始化库，然后可以获取浏览器信息作为Browser结构体。

import (
	"fmt"
	bgo "github.com/digitalcrab/browscap_go"
)

func main() {
	// 初始化库，加载browscap.ini文件
	if err := bgo.InitBrowsCap("browscap.ini", false); err != nil {
		panic(err)
	}
	
	// 解析浏览器User-Agent字符串
	browser, ok := bgo.GetBrowser("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36")
	if !ok || browser == nil {
    	panic("Browser not found")
	} else {
    	// 输出浏览器信息
    	fmt.Printf("Browser = %s [%s] v%s\n", browser.Browser, browser.BrowserType, browser.BrowserVersion)
    	fmt.Printf("Platform = %s v%s\n", browser.Platform, browser.PlatformVersion)
    	fmt.Printf("Device = %s [%s] %s\n", browser.DeviceName, browser.DeviceType, browser.DeviceBrand)
    	fmt.Printf("IsCrawler = %t\n", browser.IsCrawler())
    	fmt.Printf("IsMobile = %t\n", browser.IsMobile())
	}
}

示例说明

1. 首先使用InitBrowsCap函数初始化库，参数为browscap.ini文件路径和一个布尔值
2. 然后使用GetBrowser函数解析浏览器User-Agent字符串，返回浏览器信息结构体和是否成功的标志
3. 浏览器信息结构体包含以下常用字段:
   • Browser: 浏览器名称
   • BrowserType: 浏览器类型
   • BrowserVersion: 浏览器版本
   • Platform: 操作系统平台
   • PlatformVersion: 操作系统版本
   • DeviceName: 设备名称
   • DeviceType: 设备类型
   • DeviceBrand: 设备品牌
4. 还提供了便捷方法:
   • IsCrawler(): 判断是否是爬虫
   • IsMobile(): 判断是否是移动设备
