ios - 如何使用swift在谷歌驱动器中创建文件夹和文件

Question

我正在使用 google drive SDK 创建文件夹，但无法创建。我可以登录并获取所有文件和文件夹，但无法创建。

我正在使用 swift 并使用了这段代码

let metaData = GTLRDrive_File()
    metaData.name = "xyz"
    metaData.mimeType = "application/vnd.google-apps.folder"
    let querys = GTLRDriveQuery_FilesCreate.query(withObject: metaData, uploadParameters: nil)

    querys.fields = "id"

    //service.executeQuery(querys, delegate: self, didFinish: nil)

    self.service.executeQuery(querys) { (ticket:GTLRServiceTicket, object:Any?, error:Error?) in
        // Put your completion code here
    }

但无法创建文件夹。谁能帮我吗。提前致谢。

    func chilkatTest() {
        var success: Bool = true

    //  It requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  This example uses a previously obtained access token having permission for the
    //  Google Drive scope.

    let gAuth = CkoAuthGoogle()
    gAuth.AccessToken = "GOOGLE-DRIVE-ACCESS-TOKEN"

    let rest = CkoRest()

    //  Connect using TLS.
    var bAutoReconnect: Bool = true
    success = rest.Connect("www.googleapis.com", port: 443, tls: true, autoReconnect: bAutoReconnect)

    //  Provide the authentication credentials (i.e. the access token)
    rest.SetAuthGoogle(gAuth)

    //  -------------------------------------------------------------------------
    //  A multipart upload to Google Drive needs a multipart/related Content-Type
    rest.AddHeader("Content-Type", value: "multipart/related")

    //  Specify each part of the request.

    //  The 1st part is JSON with information about the file.
    rest.PartSelector = "1"
    rest.AddHeader("Content-Type", value: "application/json; charset=UTF-8")

    let json = CkoJsonObject()
    json.AppendString("name", value: "testHello.txt")
    json.AppendString("description", value: "A simple file that says Hello World.")
    json.AppendString("mimeType", value: "text/plain")

    //  To place the file in a folder, we must add a parents[] array to the JSON
    //  and list the folder id's.  It's possible for a file to be in multiple folders at once
    //  if it has more than one parent.  If no parents are specified, then the file is created
    //  in the My Drive folder.
    //  Note: We'll assume we already have the id if the folder.  It is the id's that are specified here,
    //  not the folder names.
    var parents: CkoJsonArray? = json.AppendArray("parents")
    var folderId: String? = "0B53Q6OSTWYolY2tPU1BnYW02T2c"
    parents!.AddStringAt(-1, value: folderId)
    parents = nil

    rest.SetMultipartBodyString(json.Emit())

    //  The 2nd part is the file content, which will contain "Hello World!"
    rest.PartSelector = "2"
    rest.AddHeader("Content-Type", value: "text/plain")

    var fileContents: String? = "Hello World!"
    rest.SetMultipartBodyString(fileContents)

    var jsonResponse: String? = rest.FullRequestMultipart("POST", uriPath: "/upload/drive/v3/files?uploadType=multipart")
    if rest.LastMethodSuccess != true {
        print("\(rest.LastErrorText)")
        return
    }

    //  A successful response will have a status code equal to 200.
    if rest.ResponseStatusCode.integerValue != 200 {
        print("response status code = \(rest.ResponseStatusCode.integerValue)")
        print("response status text = \(rest.ResponseStatusText)")
        print("response header: \(rest.ResponseHeader)")
        print("response JSON: \(jsonResponse!)")
        return
    }

    //  Show the JSON response.
    json.Load(jsonResponse)

    //  Show the full JSON response.
    json.EmitCompact = false
    print("\(json.Emit())")

    //  A successful response looks like this:
    //  {
//   "kind": "drive#file",
    //    "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
    //    "name": "Untitled",
    //    "mimeType": "text/plain"
    //  }

    //  Get the fileId:
    print("fileId: \(json.StringOf("id"))")

}
