使用 chromes 开发工具模仿从 www 到 bittrex 的 websocket 连接并不是什么大问题：

GET https://socket.bittrex.com/signalr/negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22c2%22%7D%5D&_=1524596108843

这将返回一个令牌

"ConnectionToken":"gbLsm8C6Jck1mQTTFjmuIv5qgUuMZz/kXU1s+fAnjnW
qUFQocNBfp3VOrd/y0acxWL5Fv7MZ54heRddLYZS+EMhLnaPPQiSZblvgJPCbLKqZTIkb"

这需要与：

wss://socket.bittrex.com/signalr/connect? 
transport=webSockets&clientProtocol=1.5&connectionToken=

然后有一些命令发送到 websocket：

{"H":"c2","M":"SubscribeToSummaryLiteDeltas","A":[],"I":0}
{"H":"c2","M":"SubscribeToExchangeDeltas","A":["BTC-TRX"],"I":1}
{"H":"c2","M":"QueryExchangeState","A":["BTC-TRX"],"I":2}

这会生成有关所选代码 BTC-TRX 的 bittrex 流数据。但这里的事情开始变得奇怪：

这是框架的样子：

    {"C":"d-C95D047D-E,0|OHjr,0|OHjs,2|CW,6116","M":[{"H":"C2","M":"uE","A":["dY+7DsIwDEX/xXOI7NiOnYwwg0TpwENd+QnUfydtBQKp9ear4yPfFxyhwr4/7PruCgFOUJO4SoA71McL+lsLAnRQMeI0xhzg3EKXQpEFzUvyMayhiWaUOJtqLCZKonkcAly+cvyXl/lCHKOyaxbDdbUuamMXzhELk5lvvKE+s0yoyWPKVIhwg81LO8OcNCZOGQn5g9IPSuyLtq1To2drNIxv"]}]}

它当然看起来像 base64，但解码它给了我类似的东西：

u����0E��s��؎��0�D��C]���'m����#��¾?��NP��J�;��[tP1�4� ��B�B��K�1���f�8�j,&J�y\�r����B��k�u�.jc�o��>�L��c �T�p��K;Ü4&N���J싶�S�gk4�o

有没有人想出如何把它变成可读的数据？

要解码响应的编码部分，请按如下方式进行（在 python 3.8.2 提示符下方）：

>>> import zlib
>>> import base64
>>> val = b'dY+7DsIwDEX/xXOI7NiOnYwwg0TpwENd+QnUfydtBQKp9ear4yPfFxyhwr4/7PruCgFOUJO4SoA71McL+lsLAnRQMeI0xhzg3EKXQpEFzUvyMayhiWaUOJtqLCZKonkcAly+cvyXl/lCHKOyaxbDdbUuamMXzhELk5lvvKE+s0yoyWPKVIhwg81LO8OcNCZOGQn5g9IPSuyLtq1To2drNIxv'
>>> zlib.decompress(base64.b64decode(val), -15)
b'{"M":"BTC-TRX","N":24854,"Z":[{"TY":2,"R":0.00000733,"Q":28491.34078928},{"TY":2,"R":0.00000721,"Q":136755.97451456}],"S":[{"TY":0,"R":0.00000739,"Q":480.53856470},{"TY":2,"R":0.00000751,"Q":738436.09317788},{"TY":2,"R":0.00000758,"Q":310528.26191108},{"TY":2,"R":0.00000763,"Q":70625.23260103},{"TY":1,"R":0.00001388,"Q":0.0}],"f":[]}'

请注意-15decompress 方法的第二个参数。使用该参数，该decompress函数对应rawInflate于等效的 javascript 库。

响应似乎（至少在 Python 世界中）受b64decode()and约束decompress()。

message = decompress(b64decode(message))
