Variables

var API_ROOT string

当前项目根目录

var DisableCache bool

DisableCache will disable caching of the home directory. Caching is enabled by default.

Functions

func CheckFileIsExist

func CheckFileIsExist(filename string) bool

*

• 判断文件是否存在 存在返回 true 不存在返回false

func DeCompress

func DeCompress(zipFile, dest string) error

解压

func DeleteFile

func DeleteFile(filePath string) error

func Dir

func Dir() (string, error)

Dir returns the home directory for the executing user.

This uses an OS-specific method for discovering the home directory. An error is returned if a home directory cannot be detected.

func Expand

func Expand(path string) (string, error)

Expand expands the path to include the home directory if the path is prefixed with `~`. If it isn't prefixed with `~`, the path is returned as-is.

func GetDate

func GetDate() string

返回当前时间

func GetFileSize

func GetFileSize(filePath string) (int64, error)

func GetMD5

func GetMD5(plainText string) string

MD5 加密字符串

func GetMd5

func GetMd5(path string) (string, error)

计算文件的md5，适用于本地文件计算

func GetMd52

func GetMd52(file io.Reader) (io.Reader, string, error)

从流中直接读取数据计算md5 并返回流的副本，不能用于计算大文件流否则内存占用很大 @return io.Reader @params file的副本

func GetParamHmacMD5Sign

func GetParamHmacMD5Sign(secret, params string) (string, error)

func GetParamHmacSHA1Sign
