I'm trying to inflate messages from a third party websocket using javascript, but receiving a pako.js
"invalid stored block lengths" error.
The sample code I'm using to implement the web socket can be found here:
https://github.com/okcoin-okex/API-docs-OKEx.com/tree/master/demo
A full working version of the code can be found implemented here:
https://github.com/Tucsky/SignificantTrades/blob/master/src/exchanges/okex.js (https://aggr.trade)
I've tried using zlib.js instead of Pako.js, but running into more difficult problems with that library.
I've tried other alternate solutions found on stackoverflow but they don't seem to do what I need.
This is the code I'm running which shows the error. https://jsfiddle.net/fwkgmvjr/
let myAPI = new WebSocket('wss://real.okex.com:10442/ws/v3');
//When the connection is first opened
myAPI.onopen = event => {
console.log('Socket opened')
myAPI.send('{"op": "subscribe", "args":["futures/ticker:ETH-USD-190927"]}')
}
myAPI.onmessage = event => {
if (event.data instanceof String) {
console.log(event.data)
} else {
try {
console.log(JSON.parse(pako.inflateRaw(event.data, {
to: 'string'
})))
} catch (err) {
console.log(err)
}
}
}
myAPI.onclose = event => {
console.log('Socket closed')
}
myAPI.onerror = event => {
console.log(`[error] ${error.message}`)
}
I expect the message from the websocket to be easily inflatable somehow.
