Abs 获取绝对路径 func Abs(path string) (string, error) pathAbs, _ := filepath.Abs("./") fmt.Println Rel 返回一个路径的相对路径 func Rel(basepath, targpath string) (string, error) fmt.Println(filepath.Rel(". /static 表示从 file指向 static 的相对路径 // 注意;路径内不能包含文件 // 当路径末尾包含文件 fmt.Println(filepath.Rel(". \static.js VolumeName 获取开头卷名 func VolumeName(path string) (v string) pathAbs, _ := filepath.Abs(" ./") fmt.Println(filepath.VolumeName(pathAbs)) // -> C: Walk 遍历目录树,并执行回调, 类似 map 报错或遍历结束,跳出
Golang-filepath 使用 获取当前目录 os.GetPWD() filepath.Abs(path) # 绝对目录 filepath.Dir(path) # 相对目录 可以 filepath.Abs (filepath.Dir(path)) 获取字符目录,前缀,后缀等方法 filepath.Split(path) filepath.Base(path) # test.txt filepath.Ext
if not any(fileEx in item for item in exclude): print(fileName) filePath = os.path.join(root,fileName) fileSize = getsize(filePath) files_size os.stat(filename).st_size FileNotFoundError: [WinError 3] The system cannot find the path specified: 解决: filePath \\" + filePath fileSize = getsize(filePath)
或者 [ERROR] Can’t start server: can’t create PID filepath: No such file or directory 错误原因 一般是由于服务器强制关机导致
合并一个开发比较久的分支到master。 使用的命令: git checkout master git merge may_dev_branch
