Я создаю игру Unity, в которой нужно использовать какое-то хранилище файлов. Из-за его примеров, документации и поддержки я решил использовать Dropbox API 2.0. Я использую код из Dropbox API-2.0 examples-SimpleTest для реализации асинхронного загрузчика файлов. Файл просто загружает файл с псевдослучайным именем * .json в папку приложения / nullJSON. Загруженные файлы - это просто * .json файлы, содержащие строку json. Ниже мой код. Поскольку Unity использует .NetCore, я не могу использовать WebRequestHandler при настройке http-клиента:
Вызовов API:
//For Game
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.Xml;
using UnityEngine.Networking;
using System.IO;
using UnityEngine.EventSystems;
using System.Net;
using UnityEngine.Networking.NetworkSystem;
using System;
using System.Net.Sockets;
//For Dropbox API
using System.Threading;
using System.Runtime.InteropServices;
using System.Net.Http;
using System.Threading.Tasks;
using System.Linq;
using Newtonsoft.Json;
using Dropbox.Api;
using Dropbox.Api.Common;
using Dropbox.Api.Files;
using Dropbox.Api.Team;
Инициализатор клиента (отвечает за настройкуHTTP / Dropbox Client):
public void dBoxSetup()
{
//Only run if the dropbox client doesn't exist.
if (dBoxClient == null)
{
//Connect to Dropbox
DropboxCertHelper.InitializeCertPinning();
httpClient = new HttpClient()
{
Timeout = TimeSpan.FromMinutes(20)
};
try
{
var config = new DropboxClientConfig("nullificationApp")
{
HttpClient = httpClient
};
dBoxClient = new DropboxClient(accessToken, config);
}
catch (HttpException e)
{
StartCoroutine(ShowMessage("Application Error: Exception reported from RPC layer", 5));
Debug.Log("Exception reported from RPC layer");
Debug.Log(" Status code: " + e.StatusCode);
Debug.Log(" Message : " + e.Message);
if (e.RequestUri != null)
{
Debug.Log(" Request uri: " + e.RequestUri);
}
}
}
}
Этот код, кажется, работает, поскольку аналитика API показывает, что он успешно соединяется, и я не получаю никаких ошибок исключения при его настройке. Создать новый файл JSON:
public async void dBoxCreate()
{
//This fucntion creates a new JSON file.
if (!IPaddr.text.Equals(""))
{
//Naming convention should have already been checked.
string defenderInfo = pathJSON();
//Create Page to Upload
await ChunkUpload(dBoxClient, jsonPath, fileName + ".json", defenderInfo);
Debug.Log("Creating file " + fileName);
StartCoroutine(ShowMessage("Creating file" + fileName, 5));
}
else
{
Debug.Log("Please provide an Opponent IP Address");
StartCoroutine(ShowMessage("Please provide an Opponent IP Address", 5));
}
}
Этот код также работает без ошибок.
Фактический загрузчик (где на самом деле возникает ошибка): /// <summary>

/// and also enable capability to track upload progerss.

private async Task ChunkUpload(DropboxClient myclient, string folder, string fileName, string contentBody)
{
Console.WriteLine("Chunk upload file...");
// Chunk size is 128KB.
const int chunkSize = 128 * 1024;
// Create a random file of 1MB in size.
//var fileContent = new byte[1024 * 1024];
//new System.Random().NextBytes(fileContent);
var fileContent = System.Text.UTF8Encoding.UTF8.GetBytes(contentBody);
using (var stream = new MemoryStream(fileContent))
{
int numChunks = (int)Math.Ceiling((double)stream.Length / chunkSize);
byte[] buffer = new byte[chunkSize];
string sessionId = null;
for (var idx = 0; idx < numChunks; idx++)
{
Console.WriteLine("Start uploading chunk {0}", idx);
var byteRead = stream.Read(buffer, 0, chunkSize);
using (MemoryStream memStream = new MemoryStream(buffer, 0, byteRead))
{
if (idx == 0)
{
var result = await myclient.Files.UploadSessionStartAsync(body: memStream);
sessionId = result.SessionId;
}
else
{
UploadSessionCursor cursor = new UploadSessionCursor(sessionId, (ulong)(chunkSize * idx));
if (idx == numChunks - 1)
{
await myclient.Files.UploadSessionFinishAsync(cursor, new CommitInfo(folder + "/" + fileName), memStream);
}
else
{
await myclient.Files.UploadSessionAppendV2Async(cursor, body: memStream);
}
}
}
}
}
}
Если быть точным, ошибка возникает в строке, которую я называю , ожидают myclient.Files.UploadSessionStartAsync () [или любой myclient.Files async метод в этом отношении].
Это исключение, которое выдает игра, что также указывает на то, что ошибка возникает с функцией, которую я упомянул выше:
ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Есть идеи о том, что происходит? Моим первым предположением было, что json был слишком большим, но это явно не так. Следующим моим предположением будет то, что это будет WebRequestHandler, так как приложение SimpleTest прекрасно работает, но тогда возникает проблема, заключающаяся в том, что .NetCore предположительно не поддерживает WebRequestHandler. Любые рекомендации / идеи? <Чем быстрее ответ, тем лучше. </p>
