(C# UWP/WinRT) OneDrive -- Streaming File Upload

See more OneDrive Examples

Uploads a local file by path to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call. Uploading in this way only supports files up to 4MB in size. The 4MB limitation is a OneDrive limitation, not a Chilkat limitation. (See the other example(s) for uploading larger files.)

Note: This example requires Chilkat v9.5.0.68 or greater.

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

Chilkat.Http http = new Chilkat.Http();

// Use your previously obtained access token here:
// See the following examples for getting an access token:
//    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
//    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
//    Refresh Access Token (Azure AD v2.0 Endpoint).
//    Refresh Access Token (Azure AD Endpoint).

// (Make sure your token was obtained with the Files.ReadWrite scope.)
http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN";

// To upload in a single HTTP request, send a PUT request such as the following:

// 	PUT /v1.0/me/drive/root:/{item-path}:/content
// 	Content-type: text/plain
// 	Content-Length: <the actual content length>
// 
// 	The contents of the file goes here.

// Note: This example can upload any type of file.
// Chilkat automatically adds the Content-Length header.

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.HttpVerb = "PUT";
// If not using "me", then the path should be /v1.0/users/{id | userPrincipalName}/...
req.Path = "/v1.0/me/drive/root:/someFolder/penguins.jpg:/content";
// Indicate the local file to be streamed in the upload.
req.StreamBodyFromFile("qa_data/jpg/penguins.jpg");
// If you're uploading a file and don't know what the Content-Type should be,
// just use "application/octet-stream".  See below for an example..
req.ContentType = "image/jpeg";

// In this case, we're uploading the same JPG file but instead of providing "image/jpeg" for the
// Content-Type, we provide "application/octet-stream".  ("application/octet-stream" is the general
// HTTP content-type used for anything unkown.  "octet" is a synonym for "byte".  It's just a way of
// saying: Here's a stream of bytes that comprise the file.)

// Also, you'll notice in the successful JSON response (below), that Microsoft automatically
// detected the Content-Type as "image/jpeg", because the mimeType is set as such.
// It is likely Microsoft set the MIME type (i.e. Content-Type) based on the file extension, or even better
// it may have determined the MIME type by examining the initial bytes of the file to find the standard 
// identifying markers that signify common file types such as PDF, JPG, ZIP, and many more.

// In a nutshell:  Don't worry about setting the ContentType precisely. If you know it, great.  If not, just
// use "application/octet-stream".
