PHP有内置函数：

file_put_contents_() 函数把一个字符串写入文件中

golang 有没有这样的使用起来很方便的函数进行写入操作呢？

ioutil.WriteFile
ioutil.ReadFile

https://golang.org/pkg/io/ioutil/

内置函数,没有,自己封装一个呗.

func main() {
????writeFile("1.txt", "xxx")
}

func writeFile(filename string, content string) bool {
????_, err := os.Stat(filename)
????if err != nil {
????????if !os.IsExist(err) {
????????????os.Create(filename)
????????}
????}
????file, err := os.OpenFile(filename, os.O_APPEND|os.O_WRONLY, os.ModeAppend)
????defer file.Close()
????if err != nil {
????????return false
????}
????_, err = file.WriteString(content)
????if err != nil {
????????return false
????}
????return true
}

ioutil.WriteFile()这个方法应该可以满足你的需求。直接将字节写入到文件

// WriteFile writes data to a file named by filename.
// If the file does not exist, WriteFile creates it with permissions perm
// (before umask); otherwise WriteFile truncates it before writing.
func WriteFile(filename string, data []byte, perm os.FileMode) error {
    f, err := os.OpenFile(filename, os.O_WRONLY|os.O_CREATE|os.O_TRUNC, perm)
    if err != nil {
        return err
    }
    _, err = f.Write(data)
    if err1 := f.Close(); err == nil {
        err = err1
    }
    return err
}

拿走，不用谢！
