Microsoft Virtual Academy Sky. Drive

Sky. Drive overview • Microsoft’s cloud storage solution for files and photo sharing • Guidelines for using Sky. Drive in Windows 8 Apps – Upload data in response to user action • Apps are allowed to store data without user interaction – Use Sky. Drive for what it does best • Documents, photos, etc. – Don’t undermine trust • Respect user security and privacy • Warn if data is public, etc.

Where to store app data in Sky. Drive • Don’t scatter data around Sky. Drive • Follow this pattern: – [Sky. Drive root] • Sub folder: Application. Data – Sub folder: [Application Name] ([Publisher Name or Company Name]) » Files…

Sky. Drive API Core Concepts • Interact with files using HTTP operations: – POST / PUT to upload – GET to download – MOVE / COPY to move or copy without downloading – The SDK wrappers these operations for you: • Live. Connect. Client. Post. Async • Live. Connect. Client. Get. Async • Etc. • Permissions – Inherited from parent object up the folder hierarchy

Useful folder and file properties • id - prefixed with file or folder – i. e. “file. a 6 b 2 a 7 e 8 f 2515 e 5 e. A 6 B 2 A 7 E 8 F 2515 E 5 E!126” • name – user supplied display name – i. e. “Episode. Notes. txt” • description • type – file, folder, album, etc. • source – if a file, the path to download the file – https: //. .

Working with Sky. Drive API • Important types: – Live. Connect. Session – Live. Connect. Client • Requires a valid session • Required scope: – wl. skydrive - Read access – wl. skydrive_update – read and write access – Live. Operation. Result • contains a dynamic dictionary containing resultant key/value pairs

Retrieving file or folder properties • Supply the item. Id as either an id or one of the few friendly names: • file. a 6 b 2 a 7 e 8 f 2515 e 5 e. A 6 B 2 A 7 E 8 F 2515 E 5 E!126 • /me/skydrive

Result properties can be access via dynamic • Warning: no type safety or compiler checks!

Understanding folder and file hierarchy • Some folders are accessed by Folder ID – Example: folder. a 6 b 2 a 7 e 8 f 2515 e 5 e. A 6 B 2 A 7 E 8 F 2515 E 5 E!126 • Some folders are accessed by name – /me - details about the signed in user – /me/skydrive – root of your Sky. Drive folder – /me/calendars – /me/contacts – /me/events • List files by obtaining the containing folder id

Download a file: Step 1 : Get folders of “/me/skydrive” • Imagine we want to download filename. txt: – /me/skydrive/directory 1/directory 2/filename. txt • In order to retrieve a list of files and folders contained in directory 1 (and we don’t know directory 1’s id), we first need to get a list of the folders in /me/skydrive

Download a file: Step 2 : Get “directory 1” from list • Once we have the list of files and folders (from /me/skydrive), we can find directory 1 and its id property: – id = folder. 96 a 6 fb 5 ab 7 b 940 c 6. 96 A 6 FB 5 AB 7 B 940 C 6!123

Download a file: Step 3 : Get folders of “directory 1” • We use the Folder Id to find the folders in directory 1, so we can find the id for directory 2:

Download a file: Step 5 : Get files of “directory 2” • We repeat the last few steps and get directory 2’s id, – directory 2 Id = folder. bb 1 b 4 E 12 b 9 f 9414 f. BB 1 B 4 E 12 B 9 F 9414 F!231 • We use can get a list of files (and folders) in directory 2:

Download a file: Step 6 : Get “file. txt” file url • We can the find the properties for filename. txt and the path we need to download it:

Download a file: Step 7 : Create local target • Now we have the download path, we need to create a local Storage. File where we will write the downloaded file

Download a file: Step 8 : Create local target • Use the download path – Note: uses the background downloader

Get a file, recap 1. Get folders of “/me/skydrive” 2. Get “directory 1” from list 3. Get folders of “directory 1” 4. Get “directory 2” from list 5. Get files of “directory 2” 6. Get “file. txt” file url 7. Create local target 8. Download to target
