"socketServer": ["http://192.168.12.16:8080"],//地址前缀不要使用https,如果使用https, 客户端会用wss连接后台，传递的是加密内容，后台websocketserver,会会报无法解释错误，返回400
2. 后台app/config.py, 里面更改FRONTEND_CONFIG_FILE="./app/testnet.json
ED_CONTRACT_ADDR = '0x228344536a03C0910Fb8Be9C2755c1a0bA6f89E1 //以太坊测试网络部署etherdelta, 测试网络地址：0x228344536a03c0910fb8be9c2755c1a0ba6f89e1
3. 用parity 同步:
.\parity --chain ropsten --bootnodes "enode://94c15d1b9e2fe7ce56e458b9a3b672ef11894ddedd0c6f247e0f1d3487f52b66208fb4aeb8179fce6e3a749ea93ed147c37976d67af557508d199d9594c35f09@192.81.208.223:30303,enode://30b7ab30a01c124a6cceca36863ece12c4f5fa68e3ba9b0b51407ccc002eeed3b3102d20a88f1c1d3c3154e2449317b8ef95090e77b312d5cc39354f86d5d606@52.176.7.10:30303,enode://865a63255b3bb68023b6bffd5095118fcc13e79dcf014fe4e47e065c350c7cc72af2e53eff895f11ba1bbb6a2b33271c1116ee870f266618eadfc2e78aa7349c@52.176.100.77:30303"
同步很慢我从2018-03-06 18:09:04开始，到第二天7号10：43，才同步到 127/617
