使用私有IPFS网络测试 IPFS Python Client

1. 部署私有IPFS网络

1. 建立3个节点的IPFS网络，在 docker-compose.yml 文件中写入下面内容：

   version: '3'
   services:
    ipfs-node1:
      image: ipfs/go-ipfs
      restart: unless-stopped
      ports:
       - "7000:4001"
       - "9000:5001"
       - "8080:8080"
      volumes:
       - ./node1:/home
   
    ipfs-node2:
      image: ipfs/go-ipfs
      restart: unless-stopped
      ports:
       - "7001:4001"
       - "9001:5001"
       - "8081:8080"
      volumes:
       - ./node2:/home
   
    ipfs-node3:
      image: ipfs/go-ipfs
      restart: unless-stopped
      ports:
       - "7002:4001"
       - "9002:5001"
       - "8082:8080"
      volumes:
       - ./node3:/home
   

2. docker-compose up -d
3. 随便进入一个node进行测试，dokcer-compose exec ipfs-node1 sh
4. 使用 ipfs swarm peers 查看连接状态
5. echo ‘This is node1!’ > node1.txt
6. ipfs add node1.txt 得到hash值 xxx
7. ipfs cat “node1.txt hash xxx” 查看文件

2. 使用 IPFS Python Client 测试

1. pip install ipfsapi
2. python 测试：
3. import ipfsapi
4. api = ipfsapi.connect(‘xxx.xxx.xxx.xxx’, 9001)
5. api.cat(“node1.txt hash xxx”)
6. api.add(“hello.txt”)
7. api.id() # 查看 id 信息等
8. api.get(“node1.txt hash xxx”) # 下载文件
9. api.swarm.peers() # 查看连接状态
