84+ 如何使用STS(临时密钥)来挂载bucket
85+
86+ ```
87+ 参考挂载示例
88+ ./cosfs 1252448703:rabbitliu /mnt/rabbit/ -ourl=http://cn-south.myqcloud.com -odbglevel=info -oallow_other -ocam_role=sts -opasswd_file=/tmp/passwd-jimmy-sts
89+
90+ 其中 -ocam_role=sts 是必须的参数
91+
92+ -opasswd_file 含义和之前一致,文件名和路径可以任意指定
93+ 但是文件内容需要以以下格式提供
94+ COSAccessKeyId=AKID5yc1B6BEwRikX8gaQ1NTIrAE2ay92mFS
95+ COSSecretKey=80e1A3h5FBtNbcPxGPL3ZqthFYdU6TbY
96+ COSAccessToken=109dbb14ca0c30ef4b7e2fc9612f26788cadbfac3
97+ COSAccessTokenExpire=2017-08-29T20:30:00
98+
99+ 其中COSAccessTokenExpire 代表临时token过期时间,本地时间,格式需要和例子中一致
100+ cosfs会根据这个时间来判断是否要重新加载配置来获取到最新的配置
101+
102+ 其它三个参数需要向CAM申请获取
103+
104+
105+ ```
