1.基本用法 (需要已经有一个运行的 IPFS 服务实例)
import ipfshttpclient
api = ipfshttpclient.connect('/ip4/192.168.107.216/tcp/5001/http')
res = api.add('test.txt')
res
{'Hash': 'QmWxS5aNTFEc9XbMX1ASvLET1zrqEaTssqt33rVZQCQb22', 'Name': 'test.txt'}
api.cat(res['Hash'])
'fdsafkljdskafjaksdjf\n'
2.管理功能
api.id()
{'Addresses': ['/ip4/127.0.0.1/tcp/4001/ipfs/QmS2C4MjZsv2iP1UDMMLCYqJ4WeJw8n3vXx1VKxW1UbqHS',
'/ip6/::1/tcp/4001/ipfs/QmS2C4MjZsv2iP1UDMMLCYqJ4WeJw8n3vXx1VKxW1UbqHS'],
'AgentVersion': 'go-ipfs/0.4.10',
'ID': 'QmS2C4MjZsv2iP1UDMMLCYqJ4WeJw8n3vXx1VKxW1UbqHS',
'ProtocolVersion': 'ipfs/0.1.0',
'PublicKey': 'CAASpgIwgg ... 3FcjAgMBAAE='}
3.传入API参数
api.pin_ls(type='all')
{'Keys': {'QmNMELyizsfFdNZW3yKTi1SE2pErifwDTXx6vvQBfwcJbU': {'Count': 1,
'Type': 'indirect'},
'QmNQ1h6o1xJARvYzwmySPsuv9L5XfzS4WTvJSTAWwYRSd8': {'Count': 1,
'Type': 'indirect'},
…
4.添加目录，指定文件名类型匹配
api.add('photos', match='*.jpg')
[{'Hash': 'QmcqBstfu5AWpXUqbucwimmWdJbu89qqYmE3WXVktvaXhX',
'Name': 'photos/photo1.jpg'},
{'Hash': 'QmSbmgg7kYwkSNzGLvWELnw1KthvTAMszN5TNg3XQ799Fu',
'Name': 'photos/photo2.jpg'},
{'Hash': 'Qma6K85PJ8dN3qWjxgsDNaMjWjTNy8ygUWXH2kfoq9bVxH',
'Name': 'photos/photo3.jpg'}]
5.递归添加目录
api.add('fake_dir', recursive=True)
[{'Hash': 'QmQcCtMgLVwvMQGu6mvsRYLjwqrZJcYtH4mboM9urWW9vX',
'Name': 'fake_dir/fsdfgh'},
{'Hash': 'QmNuvmuFeeWWpxjCQwLkHshr8iqhGLWXFzSGzafBeawTTZ',
'Name': 'fake_dir/test2/llllg'},
{'Hash': 'QmX1dd5DtkgoiYRKaPQPTCtXArUu4jEZ62rJBUcd5WhxAZ',
'Name': 'fake_dir/test2'},
{'Hash': 'Qmenzb5J4fR9c69BbpbBhPTSp2Snjthu2hKPWGPPJUHb9M',
'Name': 'fake_dir'}]
6.辅助函数，添加字符串和JSON等资源
lst = [1, 77, 'lol']
client.add_json(lst)
'QmQ4R5cCUYBWiJpNL7mFe4LDrwD6qBr5Re17BoRAY9VNpd'
client.get_json(_)
[1, 77, 'lol']
7.综合
import ipfshttpclient
# 连接IPFS，需要先启动节点服务器daemon
api = ipfshttpclient.connect('/ip4/192.168.107.216/tcp/5001/http')
# 查看节点ID
api.id()
# 上传文件
res = api.add('test.txt')
# 上传目录
res = api.add('pub_dir', recursive=True)
# 查看文件内容
res = api.cat('QmWxS5aNTFEc9XbMX1ASvLET1zrqEaTssqt33rVZQCQb23')
# 下载文件
res = api.get('QmWxS5aNTFEc9XbMX1ASvLET1zrqEaTssqt33rVZQCQb23')
