1、导入DLL 会有平台不兼容的问题，这里导出SDK源代码。
2、导入aliyun_oss_dotnet_sdk_2_8_0src 内代码 放入unity 工程。
3、会报 HttpUtils 里面的一个异常错误
var mimeLines = Properties.Resources.MimeData.ToString().Split('n');//异常产生处
原因是这个 MimeData 无法通过ResourceManager.GetString 获取。
源代码
//internal static string MimeData {
// get {
// return ResourceManager.GetString("MimeData", resourceCulture);
// }
//}
修改为
internal static readonly string MimeData =

这样就可以正常使用SDK 功能了。
4、_addInternalMethod这个引用永远为空，原因就是.net40里WebHeaderCollection这里根本没有AddInternal这个函数，
//var internalMethodName = (_isMonoPlatform == true) ? "AddWithoutValidate" : "AddInternal";
全部使用 AddWithoutValidate
5、Unity Webgl 无法正常下载ossclient 文件。
修改为url 去下载。
public void DownLoadFile(string _strFile, string _strFilePath,Action
{
this.fileName = _strFile;
this.filePath = _strFilePath;
Debug.Log("DownLoadFile==============");
var client = new OssClient(Config.EndPoint, Config.AccessKeyId, Config.AccessKeySecret);
try
{
Debug.Log("DownLoadFile _strFile========" + _strFile);
Debug.Log("DownLoadFile _strFilePath===========" + _strFilePath);
var req = new GeneratePresignedUriRequest(Config.Bucket, _strFile, SignHttpMethod.Get);
var uri = client.GeneratePresignedUri(req);
Debug.Log("uri======" + uri.OriginalString);
StartCoroutine(DownUrl(uri.OriginalString, _strFilePath, (succ) =>{
callback?.Invoke(succ);
}));
}
catch (OssException ex)
{
Debug.Log("Failed with error code:"+ ex.ErrorCode + "; Error info: "+ ex.Message + ".RequestID: HostID:"+ ex.HostId.ToString());
}
catch (Exception ex)
{
Debug.Log("Failed with error info:"+ ex.Message);
}
}
IEnumerator DownUrl(string downloadingUrl,string _strFilePath, Action
{
//发送请求
UnityWebRequest webRequest = UnityWebRequest.Get(downloadingUrl);
yield return webRequest.SendWebRequest();
if (webRequest.isHttpError || webRequest.isNetworkError)
{
Debug.Log("Download Error:" + webRequest.error);
callback?.Invoke(false);
}
else
{
Debug.Log("DownUrl==============");
//获取二进制数据
var _Filedata = webRequest.downloadHandler.data;
using (var file = File.Open(_strFilePath, FileMode.OpenOrCreate))
{
int length = (int)_Filedata.Length;
file.Write(_Filedata, 0, length);
}
callback?.Invoke(true);
}
}
6、Unity Webgl 上传文件问题。
ossclient 上传文件
ossClient.PutObject(signedUrl, stream); 会因为缺少webgl 库 上传失效。
var generatePresignedUriRequest = new GeneratePresignedUriRequest(Config.Bucket, _strFile, SignHttpMethod.Put);
var signedUrl = ossClient.GeneratePresignedUri(generatePresignedUriRequest);
// 使用签名URL上传文件。
StartCoroutine(UpLoadPut(signedUrl, bytes, _strFile));
用 UnityWebRequset 会出403 签名不匹配的错误。这里用BestHttp 插件 实现现下面的方法。就可以正常上传连接 文件和数据了。
IEnumerator UpLoadPut(Uri url, string data,string fileName)
{
var request = new HTTPRequest(url,HTTPMethods.Put,(op1,op2)=>{
Debug.Log("HTTPRequest: ===========" );
});
byte[] bytes = Encoding.UTF8.GetBytes(data);
request.RawData = bytes;
request.Send();
yield return null;
}
