def sign_url(self, method, key, expires, headers=None, params=None):
"""生成签名URL。
常见的用法是生成加签的URL以供授信用户下载，如为log.jpg生成一个5分钟后过期的下载链接::
>>> bucket.sign_url('GET', 'log.jpg', 5 * 60)
'http://your-bucket.oss-cn-hangzhou.aliyuncs.com/logo.jpg?OSSAccessKeyId=YourAccessKeyId\&Expires=1447178011&Signature=UJfeJgvcypWq6Q%2Bm3IJcSHbvSak%3D'
:param method: HTTP方法，如'GET'、'PUT'、'DELETE'等
:type method: str
:param key: 文件名
:param expires: 过期时间（单位：秒），链接在当前时间再过expires秒后过期
:param headers: 需要签名的HTTP头部，如名称以x-oss-meta-开头的头部（作为用户自定义元数据）、
Content-Type头部等。对于下载，不需要填。
:type headers: 可以是dict，建议是oss2.CaseInsensitiveDict
:param params: 需要签名的HTTP查询参数
:return: 签名URL。
