'unicode' 对象不支持项目分配 (HTTP 400) (Request-ID: xxx)

Question

来自openstack keystone client management doc：

我使用openstack user list查看openstack中的用户，但出现以下错误：

'unicode' object does not support item assignment (HTTP 400) (Request-ID: req-ccf9d2b6-0801-45fd-9000-7feb3783eedc)

为什么会出现这个问题？很奇怪。

在openstack cloud mariadb的keystone数据库中，我selected * from user，得到如下信息：

Answer 1

最后发现有几行的额外数据格式不对。

在快照中查看用户的额外列。数据如下：

{"email": "xxxx@xx.com", "links":"http://103.x5.xx.1/user_resource/liaoss07"}

但是要注意links不应该这样，所以，我把extra设置为{}，extra是这样不正常的。

我的解决方案是：

UPDATE user SET extra='{}' WHERE id=xxx

您也可以将电子邮件留在 {} 中。
