戈朗 :exclude trash files from google drive

Question

type listAllFilesArgs struct {
	query     string
	fields    []googleapi.Field
	sortOrder string
	maxFiles  int64
}
type Field string

func (self *Drive) listAllFiles(args listAllFilesArgs) ([]*drive.File, error) {
	var files []*drive.File
	var pageSize int64
	if args.maxFiles > 0 && args.maxFiles < 1000 {
		pageSize = args.maxFiles
	} else {
		pageSize = 1000
	}
	controlledStop := fmt.Errorf("Controlled stop")
	err := self.service.Files.List().Q(args.query).Fields(args.fields...).OrderBy(args.sortOrder).PageSize(pageSize).Pages(context.TODO(), func(fl *drive.FileList) error {
		files = append(files, fl.Files...)

		// Stop when we have all the files we need
		if args.maxFiles > 0 && len(files) >= int(args.maxFiles) {
			return controlledStop
		}

		return nil
	})

	if err != nil && err != controlledStop {
		return nil, err
	}

	if args.maxFiles > 0 {
		n := min(len(files), int(args.maxFiles))
		return files[:n], nil
	}

	return files, nil
}

func (self *Drive) newPathfinder() *remotePathfinder {
	return &remotePathfinder{
		service: self.service.Files,
		files:   make(map[string]*drive.File),
	}
}

我正在使用 go 进行我的 googledrive api 开发，下面是版本使用的详细信息，go 版本 go1.8.1 windows/amd64并进口“google.golang.org/api/drive/v3” “google.golang.org/api/googleapi”发展

err = gDrive.List(listArgs)
	if err != nil {
		fmt.Errorf("Failed to list files: %s", err)
	}

func (self *Drive) List(args ListFilesArgs) (err error) {
	listArgs := listAllFilesArgs{
		query:     args.Query,
		fields:    []googleapi.Field{"nextPageToken", "files(id,name,md5Checksum,mimeType,size,createdTime,parents)"},
		sortOrder: args.SortOrder,
		maxFiles:  args.MaxFiles,
	}
	files, err := self.listAllFiles(listArgs)
	if err != nil {
		return fmt.Errorf("Failed to list files: %s /n", err)
	}

	pathfinder := self.newPathfinder()

	if args.AbsPath {
		// Replace name with absolute path
		for _, f := range files {
			f.Name, err = pathfinder.absPath(f)
			if err != nil {
				return err
			}
		}
	}

	PrintFileList(PrintFileListArgs{
		Out:         args.Out,
		Files:       files,
		NameWidth:   int(args.NameWidth),
		SkipHeader:  args.SkipHeader,
		SizeInBytes: args.SizeInBytes,
	})

	return
}

用于 Golang 列表文件(包括垃圾)的 google drive api。如何排除垃圾文件，

Answer 1

要过滤您要从谷歌驱动器检索的文件，您需要指定搜索参数，如 "Search for Files" 中所述。 .将其作为 Q(...) 的参数传递，例如

Suppose you want to search for pdf file with a name containing myfile and not in trashed.

然后代码看起来像

err := self.service.Files.List().
   Q("mimeType='application/pdf' and name contains 'myfile' and trashed=false")
