Load

• 说明：Load加载、解压并将路径为path的文件数据读取到默认资源对象中。prefix是非必要参数，表示存储到当前资源对象中的每个文件的前缀。

• 格式：

  func Load(path string, prefix ...string) error

• 示例：

  package main
  import "github.com/gogf/gf/v2/os/gres"
  func main() {
      if err := gres.Load("../res/myfile"); err != nil {
          panic("load binary content to resource manager failed: " + err.Error())
      }
  }

Get

• 说明：Get返回指定路径的文件。

• 格式：

  func Get(path string) *File

• 示例：

  )
  func main() {
      file := gres.Get("../res/myfile")
      if file == nil {
          glog.Error(gctx.New(), "get file failed!")
          return
      }
      fmt.Println("Get File Name:", file.Name())
  }

GetWithIndex

• func GetWithIndex(path string, indexFiles []string) *File

• 示例：

GetContent

• 说明：GetContent在默认资源对象中直接返回路径为path的内容。

• 格式：

  func GetContent(path string) []byte

• 示例：

  package main
  import (
      "fmt"
      "github.com/gogf/gf/v2/os/gres"
  )
  func main() {
      fileContent := gres.GetContent("../res/myfile")
      fmt.Println("Get File Content:", fileContent)
  }

Contains

• 说明：Contains检查路径为path的资源是否存在于默认资源对象中。

• 格式：

  func Contains(path string) bool

• 示例：

  package main
  import (
      "fmt"
      "github.com/gogf/gf/v2/os/gres"
  )
  func main() {
      if gres.Contains("../res/myfile") {
          fmt.Println("myfile is exist!")
      } else{
          fmt.Println("myfile is not exist!")
      }
  }

IsEmpty

• 说明：IsEmpty检查并返回资源管理器是否为空。

• 格式：

  func IsEmpty() bool

• 示例：

  package main
  import (
      "fmt"
      "github.com/gogf/gf/v2/os/gres"
  )
  func main() {
      fmt.Println(gres.IsEmpty())
      gres.Add("xxxxxxxxxxxxxxxxx")
      fmt.Println(gres.IsEmpty())
      // Output:
      // true
      // false

ScanDir

• 格式：

• 示例：

  package main
  import (
      "fmt"
      "github.com/gogf/gf/v2/os/gres"
  )
  func main() {
      files := gres.ScanDir("../res", "*.doc,*.go", true)
      if len(files) > 0 {
          for _, file := range files {
              fmt.Println("ScanDir Result:", file.Name())
          }
      }
  }

  )
  func main() {
      files := gres.ScanDirFile("../res", "*.*", true)
      if len(files) > 0 {
          for _, file := range files {
              fmt.Println("ScanDirFile Result:", file.Name())
          }
