我能够fork一个子进程,但我有问题看到该文件中发生了什么错误,并且我知道该文件有错误,因为我创建了一个没有关闭}
所以应该发生错误。使用下面的代码,我得到什么(在控制台和/或浏览器):节点fork子进程,并得到它的错误
var child = require('child_process').fork(full_path, [], {
silent: true,
});
// Tried both of these and nothing gets displayed
child.stdout.on('error', function(data){
res.write(data);
console.log(data);
});
child.stderr.on('error', function(data){
res.write(data);
console.log(data);
});
这里是子进程:
var sys = require('sys');
var mustache = require('mustache');
var template = require('./templates/mypage.html');
sys.puts(template);
var view = {
"musketeers": ["Athos", "Aramis", "Porthos", "D'Artagnan"]
; // Forced error here with no closing "}"
var html = mustache.to_html(template, view);
sys.puts(html);
什么我需要做的,以显示错误?我做错了什么?
编辑
完整的脚本:
var sys = require('sys');
var config = require('./server.json');
var url = require('url');
var http = require('http');
function handleRequest(req, res){
var full_path = "";
for(var i in config){
var domain = config[i].server;
if(req.headers.host === domain){
var info = url.parse(req.url);
full_path = config[i].root + info.pathname;
}
}
console.log("Page: " + full_path);
if(full_path != ""){
var child = require('child_process').fork(full_path, [], {
silent: true,
});
child.stdout.on('data', function(data){
res.write(data);
});
child.stdout.on('error', function(data){
res.write(data);
console.log(data);
});
child.stderr.on('error', function(data){
res.write(data);
console.log(data);
});
child.stdout.on('end', function(){
res.end();
});
}else{
res.end();
}
}
var server = http.createServer(handleRequest);
server.listen(3000, function(err){
console.log(err || 'Server listening on 3000');
});
'child.stderr'? – zerkms
我也试过了,它不起作用 –
什么“不起作用”是什么意思?你试过什么? – zerkms
