安装python couchDb库:

https://pypi.python.org/pypi/CouchDB/0.10

连接服务器

复制代码 代码如下:

>>> import couchdb
>>> couch = couchdb.Server('http://example.com:5984/')

创建数据库
复制代码 代码如下:

>>> db = couch.create('test') # 新建数据库
>>> db = couch['mydb'] # 使用已经存在的数据库

创建文档并插入到数据库:
复制代码 代码如下:

>>> doc = {'foo': 'bar'}
>>> db.save(doc)
('e0658cab843b59e63c8779a9a5000b01', '1-4c6114c65e295552ab1019e2b046b10e')
>>> doc
{'_rev': '1-4c6114c65e295552ab1019e2b046b10e', 'foo': 'bar', '_id': 'e0658cab843b59e63c8779a9a5000b01'}

save()方法会返回'_id','_rev'字段
通过id查询数据库
复制代码 代码如下:

>>> db['e0658cab843b59e63c8779a9a5000b01']


更新文档 :
复制代码 代码如下:

>>> data = db["5fecc0d7fe5acac6b46359b5eec4f3ff"]   
>>> data['billSeconds'] = 191
>>> db.save(data)
(u'5fecc0d7fe5acac6b46359b5eec4f3ff', u'3-6b8a6bb9f2428c510dcacdd5c918d632')

遍历数据库
复制代码 代码如下:

>>> for id in db:
...     print id
...
'e0658cab843b59e63c8779a9a5000b01'

删除文档并清理数据库
复制代码 代码如下:

>>> db.delete(doc)
>>> couch.delete('test')
