还是不行，但是我改了client.dart文件里面的代码成功了，但是访问oss报错403

[huhx]

如果是提供了 stsUrl，那么需要返回的json结构如下

{
  "AccessKeyId": "AccessKeyId",
  "AccessKeySecret": "AccessKeySecret",
  "SecurityToken": "SecurityToken",
  "Expiration": "2022-03-22T11:33:06Z"
}

这是我后端返回的例子：

这是我的，顺序不一样有影响吗？

结构是没问题，你是说文件上传成功了(可以在 aliyun 网页上面检查)，但是访问文件报403?

[xaiocaiji7653]

文件没上传成功，只是从后端成功获取了sts凭证，但是用sts凭证上传文件的时候报403了，我怀疑是阿里云角色权限问题，但是重新创建了还是403
