https://github.com/aliyun/aliyun-oss-csharp-sdk/blob/d71ca46514a26e3a9f66c7e970637d8e0fa8e6d8/samples/Samples/PutObjectSample.cs#L56

代码逻辑如下：

public static string PutObjectToOss(Stream fs)
        {
            var guidStr = Guid.NewGuid().ToString("N");
            var randName = guidStr.Substring(3, 5);
            var filename = $"shopguide/imageCreateZhao1/{guidStr}.jpg";

            Stopwatch sw = new Stopwatch();
            sw.Start();
            var res = client.PutObject(bucketName, filename, fs);
            sw.Stop();

            if (res.HttpStatusCode.ToString() == "OK")
                return $"{alidomain}{filename}";
            return string.Empty;
        }

## 报错如下：

哥们解决了么，最后我们是改了配置
