今天研究了下在 unity 下做的 oss 上傳，感覺應該分享下。

下面是官網的連結文件

官網給的例子

using Aliyun.OSS;
var endpoint = "<yourEndpoint>";
var accessKeyId = "<yourAccessKeyId>";
var accessKeySecret = "<yourAccessKeySecret>";
var bucketName = "<yourBucketName>";
var objectName = "<yourObjectName>";
var localFilename = "<yourLocalFilename>";
// 建立OssClient例項。
var client = new OssClient(endpoint, accessKeyId, accessKeySecret);
try
{
    // 上傳檔案。
    client.PutObject(bucketName, objectName, localFilename);
    Console.WriteLine("Put object succeeded");
}
catch (Exception ex)
{
    Console.WriteLine("Put object failed, {0}", ex.Message);
}
 

<yourAccessKeyId>、<yourAccessKeySecret>，<yourLocalFilename>這三個引數相對簡單些，分別是你的 Oss 帳號的 Id、secret、本地檔案的路徑。
而對於 <yourEndpoint>、<yourBucketName>，<yourObjectName>卻不知所云，他們到底是個什麼，其實在 oss 裡這個都有。開啟你的 oss 後臺管理。

其中 1 代表 <yourBucketName>。2代表<yourEndpoint>，但是前面要加上 http://

<yourBucketName>就是你的最終檔案的路徑， 例如：modal/oxs/aaa.unity3d

下面是我做了 AssetsBundle後，自動上傳ab包的功能。
附上寫好的Oss單例程式碼：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
using Aliyun.OSS;
using UnityEditor;

public class AliyunOss{
	// 建立OssClient例項。
	OssClient client;
	string endpoint = "https://oss-cn-beijing.aliyuncs.com";
	string accessKeyId = "";
	string accessKeySecret = "";
	string bucketName = "abcdef";
	string objectName = "modal";
	string localFilename = "Assets/StreamingAssets";
	string outPath = "Assets/StreamingAssets"; //Application.temporaryCachePath
	#region 單例
	private static AliyunOss mSelf = null;
	public static AliyunOss Instance
	{
		get
		{
			if (mSelf == null)
			{
				mSelf = new AliyunOss();
			}
			return mSelf;
		}
	}

	AliyunOss()
	{
		client = new OssClient(endpoint, accessKeyId, accessKeySecret);

	}

	#endregion

	public void OssAb(string path,string name)
	
	{	
		try
		{
			// 上傳檔案。
			Debug.Log(path+"-----------"+objectName+path+"/"+name);
			client.PutObject(bucketName, objectName+path+"/"+name, localFilename+path+"/"+name);
			Debug.Log("Oss succeeded");
		}
		catch (Exception e)
		{
			Console.WriteLine(e);
			throw;
		}
	}
}

 

其中關鍵語句client.PutObject(bucketName, objectName+path+"/"+name, localFilename+path+"/"+name);為上傳檔案，被呼叫後是這樣的：
client.PutObject("abcdef","modal/oxs/aaa.unity3d","Assets/StreamingAssets/oxs/aaa.unity3d");

這樣是不是就理解了，如果給你解答疑惑，不要忘記點贊哦。
