这里是获得相同结果的简化代码.

Here is the stripped down version of the code that gets the same result.

using System;
using System.Net;
using System.Web.Script.Serialization;

namespace OneDriveUploadSession
{
    class Program
    {
        static void Main(string[] args)
        {
            JavaScriptSerializer jss = new JavaScriptSerializer();
            string strTokenURL = "https://login.microsoftonline.com/REDACTED.onmicrosoft.com/oauth2/v2.0/token";
            string strAppSecret = "client_id=REDACTED&scope=https%3A%2F%2Fgraph.microsoft.com%2F.default&client_secret=REDACTED&grant_type=client_credentials";
            string strUserName = "REDACTED";


            //Get Access Token
            WebClient wcAccessToken = new WebClient();

            wcAccessToken.Headers.Add("Content-Type", "application/x-www-form-urlencoded");

            string strJSONAccessToken = wcAccessToken.UploadString(strTokenURL, strAppSecret);
            dynamic dynJSONAccessToken = jss.DeserializeObject(strJSONAccessToken);
            string strAccessToken = dynJSONAccessToken["access_token"].Replace(Environment.NewLine, "");


            //Get Drive ID for specified user
            WebClient wcDriveID = new WebClient();

            wcDriveID.Headers.Add("Authorization", "Bearer " + strAccessToken);

            string strDriveJSON = wcDriveID.DownloadString("https://graph.microsoft.com/v1.0/users/" + strUserName + "/drives");
            dynamic dynDriveJSON = jss.DeserializeObject(strDriveJSON);
            string strDriveID = dynDriveJSON["value"][0]["id"];


            //Create Upload Session
            WebClient wcCreateUploadSession = new WebClient();
            string strCreateUploadSessionURL = "https://graph.microsoft.com/v1.0/drives/" + strDriveID + "/root:/test.txt:/createUploadSession";

            wcCreateUploadSession.Headers.Add("Authorization", "Bearer " + strAccessToken);
            wcCreateUploadSession.Headers.Add("Content-Type", "application/json");

            string strJSONCreateUploadSession = wcCreateUploadSession.UploadString(strCreateUploadSessionURL, "POST", "{\"item\": {\"@microsoft.graph.conflictBehavior\": \"rename\"}}");
            dynamic dynJSONCreateUploadSession = jss.DeserializeObject(strJSONCreateUploadSession);
            string strUploadSessionURL = dynJSONCreateUploadSession["uploadUrl"];


            //Delete Upload Session
            WebRequest wrDeleteUploadSession = WebRequest.Create(strUploadSessionURL);

            wrDeleteUploadSession.Method = "DELETE";
            wrDeleteUploadSession.GetRequestStream();
            wrDeleteUploadSession.GetResponse();
        }
    }
}

推荐答案

基于您的代码，您正在使用客户端凭据流(也称为仅应用程序).在这种情况下，不支持可恢复的上载.从文档:

Based on your code, you're using the client credentials flow (aka app-only). Resumable uploads are not supported in this scenario. From the documentation:

注意:此API尚不支持Files.ReadWrite.All应用程序权限.计划全面支持.

Note: The Files.ReadWrite.All application permission is not yet supported on this API. Full support is planned soon.

目前，仅使用委派权限支持断点续传.

At this time, resumable uploads are only supported using delegated permission.
