GoWebDAV

A golang WebDAV client library.

Main features

gowebdav library allows to perform following actions on the remote WebDAV server:

• create path
• get files list
• download file
• upload file
• get information about specified file/folder
• move file to another location
• copy file to another location
• delete file

Usage

First of all you should create Client instance using NewClient() function:

root := "https://webdav.mydomain.me"
user := "user"
password := "password"

c := gowebdav.NewClient(root, user, password)

After you can use this Client to perform actions, described below.

NOTICE: we will not check errors in examples, to focus you on the gowebdav library's code, but you should do it in your code!

Create path on a WebDAV server

err := c.Mkdir("folder", 0644)

In case you want to create several folders you can use c.MkdirAll():

err := c.MkdirAll("folder/subfolder/subfolder2", 0644)

Get files list

files, _ := c.ReadDir("folder/subfolder")
for _, file := range files {
    //notice that [file] has os.FileInfo type
    fmt.Println(file.Name())
}

Download file to byte array

webdavFilePath := "folder/subfolder/file.txt"
localFilePath := "/tmp/webdav/file.txt"

bytes, _ := c.Read(webdavFilePath)
ioutil.WriteFile(localFilePath, bytes, 0644)

Download file via reader

Also you can use c.ReadStream() method:

webdavFilePath := "folder/subfolder/file.txt"
localFilePath := "/tmp/webdav/file.txt"

reader, _ := c.ReadStream(webdavFilePath)

file, _ := os.Create(localFilePath)
defer file.Close()

io.Copy(file, reader)

Upload file from byte array

webdavFilePath := "folder/subfolder/file.txt"
localFilePath := "/tmp/webdav/file.txt"

bytes, _ := ioutil.ReadFile(localFilePath)

c.Write(webdavFilePath, bytes, 0644)

Upload file via writer

webdavFilePath := "folder/subfolder/file.txt"
localFilePath := "/tmp/webdav/file.txt"

file, _ := os.Open(localFilePath)
defer file.Close()

c.WriteStream(webdavFilePath, file, 0644)

Get information about specified file/folder

webdavFilePath := "folder/subfolder/file.txt"

info := c.Stat(webdavFilePath)
//notice that [info] has os.FileInfo type
fmt.Println(info)

Move file to another location

oldPath := "folder/subfolder/file.txt"
newPath := "folder/subfolder/moved.txt"
isOverwrite := true

c.Rename(oldPath, newPath, isOverwrite)

Copy file to another location

oldPath := "folder/subfolder/file.txt"
newPath := "folder/subfolder/file-copy.txt"
isOverwrite := true

c.Copy(oldPath, newPath, isOverwrite)

Delete file

webdavFilePath := "folder/subfolder/file.txt"

c.Remove(webdavFilePath)
