我对nodejs比较新,所以我将更详细地解释一下我想做什么.

我有一个网络服务器.如果请求失败,我想记录该异常的堆栈跟踪,但是提供错误页面而不是使服务器崩溃.

例如,处理请求的函数:

var Q = require('q');

var requestHandler = function () {
    // Here I get the data etc. that was requested. As this is not important, just a dummy here
    Q.resolve()
        // Now I answer the request
        .then(function (data) {
            // Dummy Code representing the sending of a response
            console.log('sending response …');
            console.log('oh no! an exception');
            // Now an Exception occurs
            throw new Error('You did something wrong!');
        })
        // If there was any error, show the error page …

在我的文章集合中,我有一个文本索引:

{
    "v" : 1,
    "key" : {
            "_fts" : "text",
            "_ftsx" : 1
    },
    "name" : "title_text_abstract_text_body_text",
    "ns" : "foo.articles",
    "weights" : {
            "abstract" : 1,
            "body" : 1,
            "title" : 1
    },
    "default_language" : "english",
    "language_override" : "language",
    "textIndexVersion" : 2
}

在我的文章集中,我有一个这样的条目:

{
    "_id" : ObjectId("5477c28c807a9cd660ccd567"),
    "title" : "Hallo Welt!",
    "author" : "foo",
    "publishDate" : ISODate("2014-11-28T17:00:00Z"),
    "language" : "de",
    "abstract" : "Mein erster Artikel!",
    "body" : "Dieser Artikel ist in deutscher Sprache.",
    "__v" : 0
}

(有在实际上不同的价值观 …
