该函数主要用来指定参数(os.O_APPEND|os.O_CREATE|os.O_WRONLY)以及文件权限(0666)来打开文件,如果打开成功返回的文件对象将被用作I/O操作funcOpenFile(namestring, flagint, perm FileMode)(*File,error) 使用os.Open家族函数和ioutil.ReadAll()读取文件示例: funcOsIoutil(namestring){iffileObj,err := os...
Then, we use the fmt.Fprintln method to append the string to a file. If we can create the info.txt file, we can view the content as: $ cat info.txt Hello worldstring Text appended tothesecondline Conclusion This piece covers file writing and appending operations in the Go programming la...
