如何在heroku中显示来自node.js的所有console.log? [英] how to show all console.log from node.js in heroku?
问题描述
我已经为node.js部署了一个node.js应用程序,但无法从我的应用程序中看到完整的console.log语句。我正在使用:
heroku日志
显示了一些日志记录,但看起来并不是完整的日志。是否有一个node.js包从部署的应用程序发送电子邮件?邮件代码:
console.log('尝试发送电子邮件等待');
var nodemailer = require(nodemailer);
var smtpTransport = nodemailer.createTransport({
服务:Gmail,
auth:{
user:myemail@gmail.com,
pass: mypw
}
});
smtpTransport.sendMail({
来自:Dikkebil,//发件人地址
至:myemail@gmail.com,//逗号分隔的接收者列表
主题:Error body,//主题行
文本:'错误正文:'+ error.body +'\\\
'+'错误类型:'+ error.type +'\\\
'+ 'error statuscode:'+ error.statusCode +'\\\
'+'error args:'+ error.arguments [0]
},function(error,response){
if(error){
console.log(error);
} else {
console.log(Message sent:+ response.message);
}
});
从heroku文档:
默认情况下,logs命令检索100个日志行。您可以通过使用--num(或-n)选项来指定
要检索的日志行数(最多1,500行)
。
blockquote>
$ heroku日志-n 200
因此,您可能需要使用
-n
选项来请求更多行。
根据收到的评论,你也可以用当前的日志流:
$ heroku logs --tail
I have deployed a node.js application to node.js but not able to see the complete console.log statements from my app. I am using:
heroku logs
Some of the logging is shown but looks like it is not the complete logs. Is there a node.js package to send emails from the deployed app? Email works fine from my localmachine btw.
Email code:
console.log('try to send email hold on'); var nodemailer = require("nodemailer"); var smtpTransport = nodemailer.createTransport({ service: "Gmail", auth: { user: "myemail@gmail.com", pass: "mypw" } }); smtpTransport.sendMail({ from: "Dikkebil", // sender address to: "myemail@gmail.com", // comma separated list of receivers subject: "Error body", // Subject line text: 'Error body: ' +error.body+ '\n'+ 'error type:' + error.type +'\n' +'error statuscode:' +error.statusCode +'\n' + 'error args:' + error.arguments[0] }, function(error, response){ if(error){ console.log(error); }else{ console.log("Message sent: " + response.message); } });
解决方案From the heroku doc:
The logs command retrieves 100 log lines by default. You can specify the number of log lines to retrieve (up to a maximum of 1,500 lines) by using the --num (or -n) option.
$ heroku logs -n 200
So probably you need to request more lines with
-n
option.As per comment received, you can also stream the current log with:
$ heroku logs --tail
Please look at the doc
