Heroku + node.js错误(Web进程无法在启动后的60秒内绑定到$ PORT) [英] Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)
问题描述
我有我的第一个node.js应用程序(本地运行正常) - 但我无法通过heroku(第一次w / heroku以及)部署它。代码如下。因此,我不会让我写这么多的代码,所以我只是说,在我的网络中本地运行代码显示没有问题。
var http = require('http');
var fs = require('fs');
var path = require('path');
$ b http.createServer(函数(请求,响应){
console.log('请求开始');
console.log(request); $如果(filePath =='./')
filePath ='./index.html';
的console.log(文件路径);
变种extname = path.extname(文件路径);
变种的contentType = 'text / html的';
开关(extname){
'case'.js':
contentType ='text / javascript';
break;
case'.css':
contentType ='text / css';
break;
}
path.exists(filePath,function(exists){
if(exists){
fs.readFile(filePath,函数(错误,内容){
if(error){
response.writeHead(500);
response.end();
}
else {
response.writeHead(200,{'Content-Type':contentType});
response.end(content,'utf-8');
}
});
}
else {
response.writeHead(404);
response.end();
}
});
})。listen(5000);
console.log('Server running at http://127.0.0.1:5000/');
任何想法?
.listen(process.env.PORT || 5000)
这样,当你在本地测试时,它仍然会听到端口5000,但它也可以在Heroku上运行。
你可以检查出的Node.js 这里 Heroku的文档。
I have my first node.js app (runs fine locally) - but I am unable to deploy it via heroku (first time w/ heroku as well). The code is below. SO doesn't let me write so much code, so I would just say that the running the code locally as well within my network shows no issue.
var http = require('http');
var fs = require('fs');
var path = require('path');
http.createServer(function (request, response) {
console.log('request starting for ');
console.log(request);
var filePath = '.' + request.url;
if (filePath == './')
filePath = './index.html';
console.log(filePath);
var extname = path.extname(filePath);
var contentType = 'text/html';
switch (extname) {
case '.js':
contentType = 'text/javascript';
break;
case '.css':
contentType = 'text/css';
break;
}
path.exists(filePath, function(exists) {
if (exists) {
fs.readFile(filePath, function(error, content) {
if (error) {
response.writeHead(500);
response.end();
}
else {
response.writeHead(200, { 'Content-Type': contentType });
response.end(content, 'utf-8');
}
});
}
else {
response.writeHead(404);
response.end();
}
});
}).listen(5000);
console.log('Server running at http://127.0.0.1:5000/');
Any idea ?
Heroku dynamically assigns your app a port, so you can't set the port to a fixed number. Heroku adds the port to the env, so you can pull it from there. Switch your listen to this:
.listen(process.env.PORT || 5000)
That way it'll still listen to port 5000 when you test locally, but it will also work on Heroku.
You can check out the Heroku docs on Node.js here.
