目录扫描
ScanDir
- 说明:扫描指定目录,可扫描文件或目录,支持递归扫描。
- 格式:
func ScanDir(path string, pattern string, recursive ...bool) ([]string, error)
func ExampleScanDir() {
// init
var (
fileName = "gflie_example.txt"
tempDir = gfile.TempDir("gfile_example_scan_dir")
tempFile = gfile.Join(tempDir, fileName)
tempSubDir = gfile.Join(tempDir, "sub_dir")
tempSubFile = gfile.Join(tempSubDir, fileName)
)
// write contents
gfile.PutContents(tempFile, "goframe example content")
gfile.PutContents(tempSubFile, "goframe example content")
// scans directory recursively
list, _ := gfile.ScanDir(tempDir, "*", true)
for _, v := range list {

}
// Output:
