我只是想让Alexa说出谷歌电子表格中的数据。我正在使用google-spreatsheet node.js模块而不是http.get()方法。
这是我的意图功能
'GetPainterIntent': function() {
// spreadsheet key is the long id in the sheets URL
var doc = new GoogleSpreadsheet('1K-dl08g8s27TgF5yMGv_Q5tBbkpRpGWrt3RkUB2mVKk');
var sheet;
async.series([
function setAuth(step) {
// see notes below for authentication instructions!
var creds = require('./creds.json');
// OR, if you cannot save the file locally (like on heroku)
/*
var creds_json = {
client_email: ' ',
private_key: ' '
}
*/
doc.useServiceAccountAuth(creds, step);
},
function getInfoAndWorksheets(step) {
doc.getInfo(function(err, info) {
console.log('Loaded doc: '+info.title+' by '+info.author.email);
sheet = info.worksheets[0];
//console.log('sheet 1: '+sheet.title+' '+sheet.rowCount+'x'+sheet.colCount);
this.emit('ask:', 'Do you want'+sheet.title+' '+sheet.rowCount+'x'+sheet.colCount);
step();
});
}
], function(err){
if( err ) {
console.log('Error: '+err);
}
});
}
在执行结果中:失败的日志,我得到的一个关键事项是......
{
"errorMessage": "RequestId: 79ed1bc9-aaee-11e7-878b-5fe3ebd777ae
Process
exited before completing request"
}
TypeError: Cannot read property 'emit' of undefined

emit内的属性是否未定义?或者你如何定义发射的属性或者我读错了吗?
答案 0 :(得分:1)
我认为问题在于您以编码方式丢失了this
,可能是因为它使用了异步系列。使用this
之类的行在顶部保存var self=this
,然后使用self.emit
代替。
