cos-python-sdk's Issues

character mapping must return integer, None or unicode

如果我添加一行

self._secret_key = str(self._secret_key)

这个错误会消失。

但是出现新的错误是：

'ascii' codec can't decode byte 0xe7 in position 2: ordinal not in range(128)

sdk里面函数命名规范不统一啊

有些函数命名用驼峰法，有些又用下划线分隔法……应该统一成python的下划线分隔形式吧

sample.py里面的例子参数顺序都是错误的

按照sample.py里的upload整了好久，都不成功，最后仔细看源码发现参数顺序都是错的。

请问在python3 里面能用吗？

secretKey 配置问题

pip install qcloud_cos 后，文件已经 copy 到了系统目录里面，没办法再去修改 conf.py 了。多个项目也无法使用不同的配置。能否改变一下配置的方式？比如用 class 实现？

只能通过文件名上传文件？

我在程序里处理好了一串文本流，那我怎样才能上传？

怎么查看目录存不存在？

cos.stat方法对文件验证不起作用，无论存在与否一概返回成功

cos上传api报错：TypeError: character mapping must return integer, None or unicode

sdk报错：
TypeError: character mapping must return integer, None or unicode

主要原因：
python 2.6的hmac不支持unicode编码导致：
http://bugs.python.org/issue5285
解决方案：
传递给api的参数进行str处理：

cos_app_id = str(info['cos_app_id'])
cos_s_id = str(info['cos_s_id'])
cos_s_key = str(info['cos_s_key'])
bucket = str(info['cos_bucket'])
cos_api = qcloud_cos.Cos(cos_app_id, cos_s_id, cos_s_key)
result = cos_api.statFile(bucket, cos_path)
