JavaScript：从Websocket中，我收到消息，作为Zlib Deflate：如何阅读或“ Unflate”或“放气” （不夸大）
这个问题是关于从WebSocket转换GZIP放气消息，并将其转换为可以应用JSON.PARSE的数组或原始文本...
***也很清楚：在此问题中：我使用来自一个加密交易所....但是，问题是关于收到的消息而不是关于Crypto Exchange的
消息，他们说“请使用Zlib Deflate”
此处的JavaScript
digifinexopen = '{"id":12312,"method":"trades.subscribe","params":["btc_usdt"]}';
digifinex_market_ws = new WebSocket("wss://openapi.digifinex.com/ws/v1/");
digifinex_market_ws.binaryType = "arraybuffer";
digifinex_market_ws.onmessage = event => digifinex_trades(event.data);
digifinex_market_ws.onopen = event => digifinex_market_ws.send(digifinexopen);
function fu_bitmex_trades (jsonx) { console.log(jsonx); }
我在
object=>[[Int8Array]]: Int8Array(1129) 0 … 99]
0: 120
1: -38
以＆lt; script; script; script; “ https://cdnjs.cloudflare.com/ajax/libs/pako/2.0.4/pako.min.js” ... 如果我做pako.deflate（jsonx）; 的
object=> Uint8Array(78) [120, 156, 1, 67, 0, 188, 255, 120, 218, 4, 192, 177, 13, 196, 32, 12, 133, 225, 93, 254, 154, 6, 174, 243, 54, 39, 66, 17, 201, 74, 36, 63, 187, 66, 236, 158, 111, 179, 34, 222, 192, 158, 114, 111, 196, 82, 121, 98, 27, 229, 63, 75, 24, 170, 57, 151, 196, 105, 220, 23, 214, 199, 175, 143, 243, 5, 0, 0, 255, 255, 32, 108, 18, 108, 62, 68, 31,
如果我添加解码器= new TextDecoder（“ utf8”）; and log（dododer.decode（jsonx））;我得到我得到
string=> x�E��xڜ��n\7����'5���*
���$pƋ Ȼ�*��g��#����|�����������������v\�//�_������������
， 我得到了我可以json.parse的原始数据????
This question is about converting a gzip deflate message from a websocket message and convert it to array OR raw text that I can apply JSON.parse on it...
*** to be also clear: In this question : i use a websocket from a crypto exchange.... but the question is about the received message NOT about crypto exchange
in the documentation they say "please use zlib deflate"
HERE THE JAVASCRIPT
digifinexopen = '{"id":12312,"method":"trades.subscribe","params":["btc_usdt"]}';
digifinex_market_ws = new WebSocket("wss://openapi.digifinex.com/ws/v1/");
digifinex_market_ws.binaryType = "arraybuffer";
digifinex_market_ws.onmessage = event => digifinex_trades(event.data);
digifinex_market_ws.onopen = event => digifinex_market_ws.send(digifinexopen);
function fu_bitmex_trades (jsonx) { console.log(jsonx); }
I have this in the log
object=>[[Int8Array]]: Int8Array(1129) 0 … 99]
0: 120
1: -38
I tried with <script src="https://cdnjs.cloudflare.com/ajax/libs/pako/2.0.4/pako.min.js" ...></script>
if I do pako.deflate(jsonx);
I get
object=> Uint8Array(78) [120, 156, 1, 67, 0, 188, 255, 120, 218, 4, 192, 177, 13, 196, 32, 12, 133, 225, 93, 254, 154, 6, 174, 243, 54, 39, 66, 17, 201, 74, 36, 63, 187, 66, 236, 158, 111, 179, 34, 222, 192, 158, 114, 111, 196, 82, 121, 98, 27, 229, 63, 75, 24, 170, 57, 151, 196, 105, 220, 23, 214, 199, 175, 143, 243, 5, 0, 0, 255, 255, 32, 108, 18, 108, 62, 68, 31,
If I add decoder = new TextDecoder("utf8"); and log(decoder.decode(jsonx)); I get
string=> x�E��xڜ��n\7����'5���*
���$pƋ Ȼ�*��g��#����|�����������������v\�//�_������������
but, HOW TO RETREIVE the array or raw data that I could json.parse ????

如果我两次解压缩您的数据，我会得到：
看起来您被压缩而不是解压缩。使用
pako.inflate（）。If I decompress your data twice, I get:
It looks like you compressed instead of decompressed. Use
pako.inflate().
