我试图用机器人构建一个松弛的应用程序,为此我需要执行几个回调函数,但它没有设法启动第三个。前两个效果不错,但最后一个从未开始,我不知道为什么。 我使用快递。
这是我的代码:
var app = express();
app.use(bodyParser());
var port = process.env.PORT || 5000;
//Fonctions de Callback
boutonSlack = function(req, res,next) { //Show the slack button to install the app
res.send('<a href="https://slack.com/oauth/authorize?scope=bot,incoming-webhook,commands,'
+'src="https://platform.slack-edge.com/img/add_to_slack.png" '
+'srcset="https://platform.slack-edge.com/img/add_to_slack.png 1x, '
+'https://platform.slack-edge.com/img/add_to_slack@2x.png 2x" /></a>');
console.log('cb0:le bouton slack s\'affiche');
next();
app.get('/redirect/',recupCode);
};
recupCode = function(req, res, next){//get the code parameter to perform the oauth process
console.log(req.query.code);
process.env.CODE = req.query.code;
console.log('cb1 : le code est récupéré');
res.send('cb1 : le code est récupéré');
https.get('https://slack.com/api/oauth.access?client_id='+process.env.CLIENT_ID+'&client_secret='+process.env.CLIENT_SECRET+'&code='+process.env.CODE, (res) => {
res.on('data', (chunk) => {
var result = JSON.parse(chunk);
console.log(JSON.stringify(result));
process.env.SLACKTOKEN = result.access_token;
process.env.SLACK_BOT_TOKEN = result.bot.bot_access_token;
});
});
console.log(process.env.SLACKTOKEN);
console.log(process.env.SLACK_BOT_TOKEN);
console.log('cb2 : le token est récupéré')
next();
app.get('/',ouvertureWebsocket);
};
ouvertureWebsocket = function (req, res, next) {//perform the rtm.start slack method to open the websocket
console.log('cb3 : ouverture du web socket');
res.send('cb3 : ouverture du websocket');
https.get('https://slack.com/api/rtm.start?token='+process.env.SLACK_BOT_TOKEN, (res) => {
res.on('data', (chunk) => {
var result = JSON.parse(chunk);
console.log(JSON.stringify(result));
});
});
res.end();
}
app.get('/',boutonSlack);
app.listen(port, function () {
console.log('Ready, listenning port '+port);
});

我建议你进一步深入研究异步代码在nodejs中的工作原理
在您的情况下,您必须放置
a b
1 1 1
2 1
3 None
4 None
2 1 None
2 None
3 1
4 None
3 1 None
2 None
3 None
4 1
在console.log(process.env.SLACKTOKEN);
console.log(process.env.SLACK_BOT_TOKEN);
console.log('cb2 : le token est récupéré')
next();
app.get('/',ouvertureWebsocket);
数据回调中。
https.get('https://slack.com/api/rtm.start?token...
