TypeError：无法读取未定义的属性“sid”
我试图发送一个短信（在Twilio的API资源pipe理器中工作），但似乎在我的节点安装下失败。 我刚刚完成卸载并重新安装没有用。
错误

码
var accountSid = 'AC*******'; var authToken = 'da********'; var fs = require('fs'), request = require('request'), cheerio = require('cheerio'), client = require('twilio')(accountSid, authToken); url = 'http://www.ozbargain.com.au'; request(url, function(error, response, html) { if (!error && response.statusCode == 200) { var $ = cheerio.load(html); var $el = $("a:contains('Xbox')"); if ($el.length) { client.messages.create({ to: "61448141065", from: "+61418739508", body: "hey", }, function(err, message) { console.log(message.sid); }); console.log($el.text()); } else { console.log('hey'); } } });
client.messages.create的callback被用作
}, function(err, message) { console.log(message.sid); });
当出现错误时，callbackerr的第一个参数将包含与错误有关的信息，而第二个参数message将是undefined 。
更新代码如下来处理错误的情况
}, function (err, message) { if (err) { // Handle error // Show appropriate message to user } else { // No error if (message.sid) { // Use sid here } } console.log(message.sid); });
你可以简单的改变console.log（message.sid）; 至
if(err) { console.log(err.message); }
Twilio开发者在这里传道。
你的代码在事物的两侧有几个错误。
client.messages.create({ to: "61448141065", from: "+61418739508", body: "hey", }, function (err, message) { console.log(message.sid); });
对于在电话号码之前缺less一个+号码，在主体之后，您需要删除一个额外的逗号。
你的最终代码应该如下所示：
var accountSid = 'AC*******'; var authToken = 'da********'; var fs = require('fs'), request = require('request'), cheerio = require('cheerio'), client = require('twilio')(accountSid, authToken); url = 'http://www.ozbargain.com.au'; request(url, function(error, response, html) { if (!error && response.statusCode == 200) { var $ = cheerio.load(html); var $el = $("a:contains('Xbox')"); if ($el.length) { client.messages.create({ to: "+61448141065", from: "+61418739508", body: "hey" }, function(err, message) { console.log(message.sid); }); console.log($el.text()); } else { console.log('hey'); } } });
我在这里testing它，并改变后，它工作得很好。
希望这可以帮助你。
更新：尝试更改您的代码只是这样的：
var accountSid = 'AC*******'; var authToken = 'da********'; var fs = require('fs'), client = require('twilio')(accountSid, authToken); client.messages.create({ to: "+61448141065", from: "+61418739508", body: "hey" }, function (err, message) { console.log(message.sid); });
这是因为你的通话失败，没有消息对象。 更换
console.log(message.sid);
同
if (err) console.log(err.message); if (message) console.log(message.sid);
然后你会看到错误信息。
