表单上传，覆盖上传方式，错误：401 bad token

Question

用Python产生的Topken，代码如下：

# Create Qiniu Upload Token
policy = qiniu.rs.PutPolicy(scope='%s:%s' % (bucket_name, 'key.png'))
policy.fsizeLimit = 1024 * 1024
policy.mimeLimit = "image/jpeg;image/png"
policy.returnBody = '{"hash": $(etag), "key": $(key)}'
policy.returnUrl = url
uptoken = policy.token()

Answer 1

要上传的文件的key是'key.png'？
