    }
    fmt.Println(utf8.FullRune(body))
    response := string(body)
    return response, nil
}
func main() {
    headers := map[string]string{
        "user-agent": "test",
    }
    content, _ := post("http://httpbin.org/post", headers, "")
    fmt.Println(content)

}

返回的content里面中文是Unicode的形式的 怎么才能输出中文形式的呢

Answer 1

import "golang.org/x/text/encoding/simplifiedchinese"

func ConvertStr2GBK(str string) string {
    //将utf-8编码的字符串转换为GBK编码
    ret, err := simplifiedchinese.GBK.NewEncoder().String(str)
    return ret   //如果转换失败返回空字符串

    //如果是[]byte格式的字符串，可以使用Bytes方法
    b, err := simplifiedchinese.GBK.NewEncoder().Bytes([]byte(str))
    return string(b)
}
