file upload to one drive

Maybe this can help you out:

Using the code:

public string OneDriveApiRoot { get; set; } = "https://api.onedrive.com/v1.0/";

Upload file to OneDrive

//this is main method of upload file to OneDrive
public async Task<string> UploadFileAsync(string filePath, string oneDrivePath)
{
//get the upload session,we can use this session to upload file resume from break point
string uploadUri = await GetUploadSession(oneDrivePath);
//when file upload is not finish, the result is upload progress,
//When file upload is finish, the result is the file information.
string result = string.Empty;
using (FileStream stream = File.OpenRead(filePath))
{
long position = 0;
long totalLength = stream.Length;
int length = 10 * 1024 * 1024;
//In one time, we just upload a part of file
//When all file part is uploaded, break out in this loop
while (true)
{
//Read a file part
byte[] bytes = await ReadFileFragmentAsync(stream, position, length);
//check if arrive file end, when yes, break out with this loop
if (position >= totalLength)
{
break;
}
//Upload the file part
result = await UploadFileFragmentAsync(bytes, uploadUri, position, totalLength);
position += bytes.Length;
}
}
return result;
}
private async Task<string> GetUploadSession(string oneDriveFilePath)
{
var uploadSession = await AuthRequestToStringAsync(
uri: $"{OneDriveApiRoot}drive/root:/{oneDriveFilePath}:/upload.createSession",
httpMethod: HTTPMethod.Post,
contentType: "application/x-www-form-urlencoded");
JObject jo = JObject.Parse(uploadSession);
return jo.SelectToken("uploadUrl").Value<string>();
}
private async Task<string> UploadFileFragmentAsync(byte[] datas, string uploadUri, long position, long totalLength)
{
var request = await InitAuthRequest(uploadUri, HTTPMethod.Put, datas, null);
request.Request.Headers.Add("Content-Range", $"bytes {position}-{position + datas.Length - 1}/{totalLength}");
return await request.GetResponseStringAsync();
}

Get Share Link: ( Javascript )

//This method use to get ShareLink, you can use the link in web or client terminal
public async Task<string> GetShareLinkAsync(string fileID, OneDriveShareLinkType type, OneDrevShareScopeType scope)
{
string param = "{type:'" + type + "',scope:'" + scope + "'}";
string result = await AuthRequestToStringAsync(
uri: $"{OneDriveApiRoot}drive/items/{fileID}/action.createLink",
httpMethod: HTTPMethod.Post,
data: Encoding.UTF8.GetBytes(param),
contentType: "application/json");
return JObject.Parse(result).SelectToken("link.webUrl").Value<string>();
}
