在 上一篇教程中, 我们创建了自动回复消息的机器人,当用户发送消息"Hello,World!"时，机器人会自动回复同一条消息!

第二课: 机器人接受比特币并立即退还用户

Hello Bitcoin!

cd mixin_labs-python-bot
source ./bin/activate
(mixin_labs-python-bot) wenewzha:mixin_labs-python-bot wenewzhang$ python app.py
ws open
-------json object begin---------
{'id': 'fd6ce766-331a-11e9-92a9-20c9d08850cd', 'action': 'LIST_PENDING_MESSAGES'}

事实上，用户可以发送任意的币种给机器人，它都能马上返还！

源代码解释

elif categoryindata == "SYSTEM_ACCOUNT_SNAPSHOT":
    rdJs = json.loads(realData)
    if ( float(rdJs["amount"]) > 0 ):
        mixin_api.transferTo(userId, rdJs["asset_id"], rdJs["amount"], "")
