reload/reload.js路线不起作用
我使用express-generator应用代码模板来创建我的节点应用
我也跟着github发布了这个包的信息 https://github.com/alallier/reload/issues/56#issuecomment-288393265
在这篇评论中他说要创建一个自定义路线来监听这个文件
app.get('/reloader', (req, res) => {
res.type('text/javascript')
res.sendFile(require.resolve('reload/lib/reload-client'))
});
但是,当我尝试重新加载不起作用时,在控制台中发生错误异常:
未捕获的DOMException:无法构建' WebSocket':URL' s 计划必须是“ws'或者' wss'。 ' HTTP'不被允许。 在新的WrappedWebSocket(:164:21)
这是我的代码(bin / www)
#!/usr/bin/env node
/**
* Module dependencies.
*/
var app = require('../app');
var reload = require('reload');
var debug = require('debug')('node1:server');
var http = require('http');
/**
* Get port from environment and store in Express.
*/
var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
/**
* Create HTTP server.
*/
var server = http.createServer(app);
reload(app); // here i'm using reload module
/**
* Listen on provided port, on all network interfaces.
*/
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
/**
* Normalize a port into a number, string, or false.
*/
function normalizePort(val) {
var port = parseInt(val, 10);
if (isNaN(port)) {
// named pipe
return val;
}
if (port >= 0) {
// port number
return port;
}
return false;
}
/**
* Event listener for HTTP server "error" event.
*/
function onError(error) {
if (error.syscall !== 'listen') {
throw error;
}
var bind = typeof port === 'string'
? 'Pipe ' + port
: 'Port ' + port;
// handle specific listen errors with friendly messages
switch (error.code) {
case 'EACCES':
console.error(bind + ' requires elevated privileges');
process.exit(1);
break;
case 'EADDRINUSE':
console.error(bind + ' is already in use');
process.exit(1);
break;
default:
throw error;
}
}
/**
* Event listener for HTTP server "listening" event.
*/
function onListening() {
var addr = server.address();
var bind = typeof addr === 'string'
? 'pipe ' + addr
: 'port ' + addr.port;
debug('Listening on ' + bind);
}
答案 0 :(得分:0)
我使用 ./ app.js 中的reload(app)
代替 ./ bin / www 强>
它在 app.js 文件中正常工作(即使我更改了此语句的位置),但是,在 ./ bin / www 文件无效。
代码(./app.js):
var express = require('express');
var path = require('path');
var reload = require('reload');
var favicon = require('serve-favicon');
var logger = require('morgan');
var expressHandlebars = require('express-handlebars');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
reload(app); // Init Reload module
