By using the websocket protocol to push Bitcoin transaction information to WeChat, it can be used as an exercise in the WSS protocol. The basic principle is to update listenKey for 30 minutes, and then subscribe to the subscription's datastream.
function main() {
var listenKey = JSON.parse(HttpQuery('https://api.binance.com/api/v1/userDataStream','',null,'X-MBX-APIKEY:'+APIKEY)).listenKey;
HttpQuery('https://api.binance.com/api/v1/userDataStream', {method:'DELETE',data:'listenKey='+listenKey}, null,'X-MBX-APIKEY:'+ APIKEY);
listenKey = JSON.parse(HttpQuery('https://api.binance.com/api/v1/userDataStream','',null,'X-MBX-APIKEY:'+ APIKEY)).listenKey;
var datastream = Dial("wss://stream.binance.com:9443/ws/"+listenKey, 100);
var update_listenKey_time = Date.now()/1000;
while (true){
if (Date.now()/1000 - update_listenKey_time > 1800){
update_listenKey_time = Date.now()/1000;
HttpQuery('https://api.binance.com/api/v1/userDataStream', {method:'PUT',data:'listenKey='+listenKey}, null,'X-MBX-APIKEY:'+ APIKEY);
Log('keep listenKey alive');
}
var data = datastream.read();
if(data){
data = JSON.parse(data);
if(data.e == 'executionReport' && data.x == 'TRADE'){
Log(data.S, data.s, 'amount is ', data.l, 'at price:', data.p, '@');
}
}
}
}
