goang ioutil.ReadFile使用相对路径

func FileCopy(src, dst string) bool {
    pwd, _ := os.Getwd()
    osPart := "/"
    if runtime.GOOS == "windows" {
        osPart = "\\"
    }
    src = pwd + osPart + src

    byteSlice, err := ioutil.ReadFile(src)
    if err != nil {
        log.Println(err)
        return false
    }
    WriteWithIoutilByte(dst, byteSlice)
    return true
}

func WriteWithIoutilByte(name string, content []byte) {
    if ioutil.WriteFile(name, content, 0644) == nil {
        log.Println("写入文件成功", name)
    }
}
