我使用 node-mailer 编写了这段代码来发送邮件。当我在 cmd 中启动服务器并转到 localhost:8080 时，它会发送两次邮件。为什么会这样？
var http = require('http');
var edge = require('edge');
var port = process.env.PORT || 8080;
var params = {
connectionString: "Data Source=localhost;Initial Catalog=node-test;Integrated Security=True",
source: "SELECT * FROM emailtable"
};
var nodemailer = require("nodemailer");
var smtpTransport = nodemailer.createTransport("SMTP",{
service: "Gmail",
auth: {
user: email,
pass: password
}
});
var getTopUsers = edge.func('sql', params);
function logError(err, res) {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.write("Error: " + err);
res.end("");
}
var minutes = 1, the_interval = minutes * 60 * 1000;
var emailText = "";
http.createServer(function (req, res) {
res.writeHead(200, { 'Content-Type': 'text/html' });
//setInterval(function() {
getTopUsers(null, function (error, result) {
emailText=""
if (error) { logError(error, res); return; }
if (result) {
res.write("<ul>");
result.forEach(function(user) {
res.write("<li>" + user.emails + "</li>");
emailText = emailText + user.emails + " ";
//console.log(emailText);
});
res.end("</ul>");
}
else {
}
console.log("just mailed")
smtpTransport.sendMail({
from: email, // sender address
to: email, // comma separated list of receivers
subject: "Hello", // Subject line
text: emailText // plaintext body
}, function(error, response){
if(error){
console.log(error);
}else{
console.log("Message sent: " + response.message);
}
});
});
//}, the_interval);
}).listen(port);
console.log("Node server listening on port " + port);
