Unity 接入騰訊雲COS對象存儲

網上沒找到COS對應.net新版本的教程，就踩完記錄下來

首先注冊騰訊雲巴拉巴拉，下載.net sdk巴拉巴拉

放到Unity項目中，刪掉不必要的測試模塊，剩下的如下圖

然后建立一個測試腳本，代碼如下

using UnityEngine;
using COSXML;
using COSXML.Auth;
using COSXML.Model.Object;
using System.IO;
using COSXML.Utils;
using System;

public class COSTest : MonoBehaviour
{
    public string appid = "";//設置騰訊雲賬戶的賬戶標識 APPID
    public string bucket = "";//存儲桶，格式：BucketName-APPID
    public string key = "exampleobject";//對象在存儲桶中的位置，即稱對象鍵
    public string secretId = ""; //雲 API 密鑰 SecretId
    public string secretKey = ""; //雲 API 密鑰 SecretKey
    public string region = "ap-guangzhou";
    // Start is called before the first frame update
    void Start()
    {
        Upload();
    }

    public void Upload() {
        CosXmlConfig config = new CosXmlConfig.Builder()
      .SetConnectionTimeoutMs(60000)  //設置連接超時時間，單位毫秒，默認45000ms
      .SetReadWriteTimeoutMs(40000)  //設置讀寫超時時間，單位毫秒，默認45000ms
      .IsHttps(true)  //設置默認 HTTPS 請求
      .SetAppid(appid) 
      .SetRegion(region) 
      .Build();

        long durationSecond = 600;          //每次請求簽名有效時長，單位為秒
        QCloudCredentialProvider qCloudCredentialProvider = new DefaultQCloudCredentialProvider(secretId,
          secretKey, durationSecond);

        CosXml cosXml = new CosXmlServer(config, qCloudCredentialProvider);

        try
        {    
            string srcPath = @"temp-source-file";//本地文件絕對路徑
            if (!File.Exists(srcPath))
            {
                // 如果不存在目標文件，創建一個臨時的測試文件
                File.WriteAllBytes(srcPath, new byte[1024]);
            }

            PutObjectRequest request = new PutObjectRequest(bucket, key, srcPath);
            //設置簽名有效時長
            request.SetSign(TimeUtils.GetCurrentTime(TimeUnit.SECONDS), 600);
            //設置進度回調
            request.SetCosProgressCallback(delegate (long completed, long total)
            {
                Debug.Log(String.Format("progress = {0:##.##}%", completed * 100.0 / total));
            });
            //執行請求
            PutObjectResult result = cosXml.PutObject(request);
            //對象的 eTag
            string eTag = result.eTag;
        }
        catch (COSXML.CosException.CosClientException clientEx)
        {
            //請求失敗
            Debug.Log("CosClientException: " + clientEx);
        }
        catch (COSXML.CosException.CosServerException serverEx)
        {
            //請求失敗
            Debug.Log("CosServerException: " + serverEx.GetInfo());        
        }
    }
}

一個簡單的上傳測試，填入自己的AppID，secretId，secretKey，bucket，region等參數
