我测试使用的是在macox下

终端执行命令安装包

brew update
brew install leptonica
brew install tesseract
brew install tesseract-lang
go get github.com/otiai10/gosseract

main.go

package

"github.com/otiai10/gosseract/v2"

client := gosseract.NewClient()
defer client.Close()
client.SetImage("/Users/xxx/Downloads/xxx.jpg")
client.SetLanguage("chi_sim")
text, _ := client.Text()
//fmt.Println(text)
reg := regexp.MustCompile("验证码: [^ ]*\\s")
yzmStr := reg.FindAllString(text, 1)
fmt.Println(yzmStr)
yzmSlice := strings.Split(text, "验证码: ")
fmt.Println(yzmSlice[1])
