Question

Google App引擎不支持文件I / O或其他低级库。

我希望能够在我的GAE项目中使用boto（1.9.167）库。

现在我遇到此错误：

    def __init__(self, profile_name, load_config, popen=subprocess.Popen):
AttributeError: 'module' object has no attribute 'Popen'

例如，是否可以跳过credentials检查并因此绕过对Popen的呼叫？

我的代码就是

s3_client = boto3.client('s3',
                         aws_access_key_id=access_key,
                         aws_secret_access_key=secret_key)
s3_client.generate_presigned_url(...)

不依赖于本地存储的任何文件。

如何避免在Google App Engine的boto中使用POpen？
