在Swift 3中为Google Drive iOS获取基本目录中的文件夹列表？

使用GoogleSignIn和GooglePiclientForrest，我已经能够登录到google，甚至可以使用从网站上获取的代码获得一个文件列表。我真正不懂的是如何按文件类型过滤请求的结果，或者如何获取子文件夹的内容。一点帮助都没有

澄清问题：而

let query = GTLRDriveQuery_FilesList.query()

query.pageSize = 10

service.executeQuery(query,
                             delegate: self,
                             didFinish: #selector(displayResultWithTicket(ticket:finishedWithObject:error:)))

完美配合

func displayResultWithTicket(ticket: GTLRServiceTicket,
                             finishedWithObject result : GTLRDrive_FileList,
                             error : NSError?) {

    if let error = error {
        print(error.localizedDescription)
        return
    }

    var text = "";

    if let files = result.files, !files.isEmpty {

        text += "Files:\n"
        for file in files {
            text += "\(file.name!) (\(file.identifier!))\n"
        }
    } else {
        text += "No files found."
    }
    print(text)
}

，我不知道如何仅获取文件夹或如何获取子文件夹中的文件。

对于列出的文件夹，我们希望像这样声明mimeType

  let root = "(mimeType = 'application/vnd.google-apps.folder' or mimeType = 'image/jpeg' or mimeType = 'image/png' or mimeType = 'application/pdf' or mimeType = 'application/epub' or mimeType = 'application/msword' or mimeType = 'application/vnd.openxmlformats-officedocument.wordprocessingml.document') and '\(root)' in parents and trashed=false"

现在，您可以将此根目录传递给您所需的需求列表

func GoogleDrivelistFiles(root : String) { //root 
    let query = GTLRDriveQuery_FilesList.query()
    query.pageSize = 100
    query.q = root
    query.fields = "files(id,name,mimeType,modifiedTime,createdTime,fileExtension,size,parents,kind),nextPageToken"
    service.executeQuery(query, completionHandler: {(ticket, files, error) in
        if let filesList : GTLRDrive_FileList = files as? GTLRDrive_FileList {

            var cloudArray = Array<FileObject>()
            if let filesShow : [GTLRDrive_File] = filesList.files {
                for Array in filesShow {
                    let name = Array.name
                    let mimeType = Array.mimeType
                    let id = Array.identifier
                    let folder = (mimeType as NSString?)?.pathExtension
                    let isfolder = true
                    let parents = Array.parents
                    var parentPath : String!
                    for arrayParents in parents! {
                        parentPath = arrayParents
                    }

                    let creationTime = Array.createdTime?.date
                    let modifiedTime = Array.modifiedTime?.date
                    let fileSize : Int!
                    let fileExtension : String!
                    if isfolder == true {
                        fileSize = 0
                        fileExtension = "Folder"
                    }else {
                        fileSize = Array.size?.intValue
                        fileExtension = Array.fileExtension
                    }
                    if folder == "folder" {
                    let content = FileObject(path: mimeType!, isFolder: true, parentPath: parentPath!, fileName: name!, creationDate: creationTime!, lastModified: modifiedTime!, fileSize: fileSize!, fileExtension: fileExtension!, fileId: id!, isSyncing: true)
                    cloudArray.append(content)
                    } else {
                        let content = FileObject(path: mimeType!, isFolder: false, parentPath: parentPath!, fileName: name!, creationDate: creationTime!, lastModified: modifiedTime!, fileSize: fileSize!, fileExtension: fileExtension!, fileId: id!, isSyncing: true)
                        cloudArray.append(content)
                    }
                }
            }
            DispatchQueue.main.async {
            self.delegate?.DataRefresh(fileObject: cloudArray)
            }

        }else {

        }
    })
}

嘿，您可以使用以下功能获取所有文件夹列表：-

func getAllfolders() {

   let root = "mimeType = 'application/vnd.google-apps.folder'"

   let query = GTLRDriveQuery_FilesList.query()
   query.pageSize = 100
   query.q = root
   query.fields = "files(id,name,mimeType,modifiedTime,createdTime,fileExtension,size),nextPageToken"

   service.executeQuery(query, completionHandler: {(ticket, files, error) in

       if let filesList : GTLRDrive_FileList = files as? GTLRDrive_FileList {
           if let filesShow : [GTLRDrive_File] = filesList.files {
               print("files \(filesShow)")
               for ArrayList in filesShow {
                   let name = ArrayList.name ?? ""
                   let id = ArrayList.identifier ?? ""
                   print("hello\(name)", id)
               }
           }
       }
   })
 }

您可以获得所有文件夹列表，包括/不包括废弃文件夹：-

func getAllfolders() {

   let root = "mimeType = 'application/vnd.google-apps.folder'" // including trash folder or add and trashed=true
   //let root = "mimeType = 'application/vnd.google-apps.folder' and trashed=false" // excluding trash folders
   let query = GTLRDriveQuery_FilesList.query()
   query.pageSize = 100
   query.q = root
   query.fields = "files(id,name,mimeType,modifiedTime,createdTime,fileExtension,size),nextPageToken"

   service.executeQuery(query, completionHandler: {(ticket, files, error) in

       if let filesList : GTLRDrive_FileList = files as? GTLRDrive_FileList {
           if let filesShow : [GTLRDrive_File] = filesList.files {
               print("files \(filesShow)")
               for ArrayList in filesShow {
                   let name = ArrayList.name ?? ""
                   let id = ArrayList.identifier ?? ""
                   print("hello\(name)", id)
               }
           }
       }
   })
 }

我现在真的很清楚为什么我在这个问题上得到了负面的评价。这是一个有效的问题，标记正确。我没有提供代码补充，因为正如我所说的，我使用的代码来自quickstart。请，如果你要投反对票，至少告诉我为什么，这样我才能对这个社区产生更积极的影响。你找到解决办法了吗。我也被这个困住了@康诺尔24601遗憾的是，我还没有找到任何学习swift中谷歌驱动API的好资源@如果我发现了，我会告诉你的，如果你发现了什么，请告诉我。可悲的是，这篇文章仍然是负面的，而且相当陈旧，所以我怀疑它是否会得到回复。我想答案可能在于在swift中发出http请求，我也不知道。嗨，你找到解决方案了吗。如果需要，请告诉我。我找到了解决办法。：）嘿，我喜欢这个解决方案！如果你能发布一个例子，那将非常有帮助！你能在选择文件夹后给出代码吗？如何获取文件夹中的文件列表？@KrutikaSonawala希望您能理解我所写的内容。：）高兴的coding@KrutikaSonawala你明白我的意思了吗？请告诉评论：）是的，我在考虑文件夹的问题，但列表给出了两者的合并结果。：）感谢您提供第二节代码。这将为我提供

GTLRDrive_文件列表0x281af3f90:{files:[0]}

。虽然我的驱动器中有文件夹。原因可能是什么？

func getAllfolders() {

   let root = "mimeType = 'application/vnd.google-apps.folder'" // including trash folder or add and trashed=true
   //let root = "mimeType = 'application/vnd.google-apps.folder' and trashed=false" // excluding trash folders
   let query = GTLRDriveQuery_FilesList.query()
   query.pageSize = 100
   query.q = root
   query.fields = "files(id,name,mimeType,modifiedTime,createdTime,fileExtension,size),nextPageToken"

   service.executeQuery(query, completionHandler: {(ticket, files, error) in
