使用process.on（'uncaughtException显示一个500错误页面 [英] Use process.on('uncaughtException to show a 500 error page

问题描述

我正在开发一个快速应用程序。

I'm developing an express app.

我目前在我的server.js中有以下内容

I currently have the following in my server.js

process.on('uncaughtException', function (err) {
    console.log( "UNCAUGHT EXCEPTION " );
    console.log( "[Inside 'uncaughtException' event] " + err.stack || err.message );
});

哪个停止服务器崩溃每次有错误，但是，它只是坐在那里...

Which stops the server crashing every time there's an error, however, it just sits there...

是否可以代替console.log发送带有错误详细信息的500错误页面？

is it possible to instead of console.log, to send a 500 error page with the error details?

推荐答案

我不认为你可以从 uncaughtException 内做出回应，因为即使没有请求发生也可能发生。

I don't think you can from within the uncaughtException do a response since that could happen even when there is no request occurring.

Express本身提供了一种方法来处理错误，如下所示：

Express itself provides a way to handle errors within routes, like so:

app.error(function(err, req, res, next){
    //check error information and respond accordingly
});
