The last time, we saw how to authenticate to a Microsoft Live OneDrive account from within a standard Windows forms application. This time, we continue on from that previous post and create routines to make working with the file list much more friendly, followed by showing how to upload and download files from the account. If you're jumping straight into this without reading the previous article, please be aware this post assumes that you already know how to authenticate to the connected OneDrive vba samples download file onedrive and send rest requests to it.
If you don't already know this, I recommend that you at least skim over it so you know how to get an accessToken. The previous article can be helpful.
This code was used to return the JSON data that represents a complete file listing of the user's root folder. This is all very useful, but parsing the folder and file list manually is a rather tricky task. File System objects in a OneDrive account can take many different forms; for example, a standard folder might look like this:. The image file, as you can see straight away, has many extra fields that a folder does not have.
It gets even more complicated with movies and Office documents, and also some folders such as "Pictures," which are as MS refers to them 'Albums'. All of this means we can't just use a single simple class object created from the JSON like we did for the 'OneDriveInfo' object as in the code above. Sidetip : Indecently, if you have Visual Studio or later, there's a great new feature built into it. NET class ready for you to use.
Be careful, though; it can get very complicated, very fast. If we look at just the basic properties that match on all the objects, we'll see that in actual fact, they vba samples download file onedrive all the same as the whole set of properties in our 'OneDriveInfo' object. This makes sense, vba samples download file onedrive, because when we get the info for the root of our OneDrive, what we're actually requesting is the file system object for our root folder, and this contains the most basic set of properties we should use.
At this point, we're going to repurpose this object as a base class, so use your Visual Studio refactoring tools or find and replace to rename your object class from 'OneDriveInfo' to something more suitable, such as ' FileSystemBase '.
We now should be able to deserialize the ' data ' property of our file list into a list of ' FileSystemBase ' objects, by using newtonsoft. Now, we could if we wanted, simply strip everything before the first '[' and after the last ']' in our data, but because we're using Newtonsoft, vba samples download file onedrive.
Figure 1: Showing the nicely typed structure. Which, vba samples download file onedrive, like the base object, has an upload location allowing you to get the file list for that folder along with the other items such as ' size ', ' type ', and share permissions.
Once we have the base object, we then can start to extend that class to take account of the other object types. In our demo root folder, for example, we have a small PNG image file. The extra data that this carries is as follows:. If we turn just those properties into a class, and then inherit that class from file system base, we should end up with a class that looks similar to this:.
It's now trivial to get all the images, and, providing you create types for them, any other file types you wish to handle. You may notice in the method for getting image lists that, when I grab the upload location to get the extra JSON information, I do a replace on the string to vba samples download file onedrive the 'content' leaf from the URL:. The upload location for a file actually points to the download link. If you request that location directly, rather than getting a JSON payload as expected, you'll actually get a byte array of the file's contents.
Because all we want is the file information, we strip this off rather than do things the other way and build the URLand then just use that as the URL to make the request to. This will, in response, return to us a single JSON object of the same format of the single entry in the original file list, but with all of the properties intact. There are many other ways we could achieve the same thing. We could, for instance, use a dynamic type and just simply populate the root file list with everything, and then build our lists on the fly from that.
This would save the extra network accesses, and if you were using this on a mobile device, vba samples download file onedrive, it's certainly something you might need to think about.
For this post, though, it serves to show how to handle the different file types easily and simply. Making a normal get request against this, as we have been doing with the other requests, will simply and efficiently return you a stream of bytes that consist entirely of the file being requested. When making a content request, there is no JSON data or any other parts to the payload, just a pure data stream containing the file requested.
How you get that file onto disk, or into memory, is entirely up to you. It is, however, sensible to use the StreamReader interface to handle it, especially if the file is something like a video file, which might end up being several hundred megabytes in size. You can download a file from your OneDrive account by adding the following method to your application:. Note that you first need to grab a copy of the file list or at the very least the single object of the file you want to download.
In the preceding method, vba samples download file onedrive, all I've done is passed in the list of our files, and the ID I want to download.
The method then uses this to get the file's original file name and upload location, makes the request to the upload location, and then finally streams the bytes into a local file with the same name as the original. And, vba samples download file onedrive, that's all there is to it. Downloading files is easy once you have the base file information.
Like everything we've done so far, this is as simple as using a web client, making a request, processing the JSON that's returned, and acting on it. In vba samples download file onedrive, you'll most likely want to pass the folder name in as a parameter, allowing you to choose where on your OneDrive you want to upload the file to. Another improvement that you'll also likely want to make is to use a file stream, rather than converting the file to a byte array before sending it.
Using a byte array is great for small files, but if you try to use that method for uploading very large files, you'll quickly consume all your available memory. Once you upload the file, you'll get the obligatory JSON response, which for a successful file should look something like this:. You'll see that this contains your file's ID, its original name, and a public link should you want to make it downloadable in a web page. The topics we've covered in the last two posts have only just begun to scratch the surface.
With the correct scope requests, you can get contact lists from Outlook and profile information. You even can access Office documents and do specialist tasks with those that you can't do on normal files. Unfortunately, its sheer size means that it's impractical for me to go any farther than I have done in these posts. Remember, too, that even though we didn't make any direct use of it, we added the LiveSDK NuGet package to our project too, so it's worth exploring that.
Look at the methods and routines in there and study the data structures vba samples download file onedrive. Finally, remember that this is just a rest-based interface. I'll be more than happy to produce posts on specific topics of interest. Read More in. Desktop-as-a-Service Designed for Any Cloud?
