通过websocket协议，将币安成交信息推送到微信，可以作为wss协议的练习。 具体原理是30分钟更新一次listenKey,然后订阅账户订阅的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, '@');
}
}
}
}
