beego - 使用beego进行多文件上传

Question

如何使用beego上传多个文件？ GetFile 方法仅返回第一个文件名。

html:

<form action="/post/save" method="POST" enctype="multipart/form-data">
    <input type="file" name="images" multiple>
</form>

在 Controller 中:

file, header, err := this.GetFile("images")
if err != nil {
    log.Println("error", err)
} else {
    log.Println("filename", header.Filename)
}

这样可以吗？

第450行

// GetFiles return multi-upload files
 files, err:=c.Getfiles("myfiles")
    if err != nil {
        http.Error(w, err.Error(), http.StatusNoContent)
        return
    }
 for i, _ := range files {`enter code here
    for each fileheader, get a handle to the actual file
    file, err := files[i].Open()
    defer file.Close()
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
    //create destination file making sure the path is writeable.
    dst, err := os.Create("upload/" + files[i].Filename)
    defer dst.Close()
    if err != nil {
    enter code here

        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
    //copy the uploaded file to the destination file
    if _, err := io.Copy(dst, file); err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
 }
