上面是错误的返回结果，
access_id跟access_key
我在我的阿里云，［ [font='Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans GB', STHeiti, 'Microsoft YaHei']Access Key管理 [font='Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans GB', STHeiti, 'Microsoft YaHei'] ］里面复制，核对了很多次了；


求解！
thanks！
