示例1: handle_get_token
# 需要导入模块: from swift.common.swob import Response [as 别名]
# 或者: from swift.common.swob.Response import host_url [as 别名]
#.........这里部分代码省略.........
X-Auth-Key: <key> or X-Storage-Pass: <key>
On successful authentication, the response will have X-Auth-Token and
X-Storage-Token set to the token to use with Swift and X-Storage-URL
set to the URL to the default Swift cluster to use.
:param req: The swob.Request to process.
:returns: swob.Response, 2xx on success with data set as explained
above.
