使用express的前哨错误日志记录不会发送任何错误

提问开始:

当我试图将错误发送到一个简单的node.js Express服务器的前哨时，我没有得到任何错误记录在前哨本身。没有设置入站筛选器，并且它不会报告过去30天内筛选的任何内容。Allowed domains设置为*，我认为这是默认设置。我使用的代码与the documentation中的示例代码大致相同。但是，当调用端点时，Sentry中不会出现任何内容，调试行也不会显示任何有关发送的错误的内容。

如何让Sentry正确捕获错误？

这是test.js

'use strict';

const express = require('express');
const Sentry = require('@sentry/node');

const app = express();

// TODO dotenv setting
const SENTRY_NODE_DSN = process.env.SENTRY_NODE_DSN || 'the ingest url from settings > client keys';

console.log(`Started logging errors at sentry on DSN ${SENTRY_NODE_DSN}`);
// Sentry
Sentry.init({
    dsn: SENTRY_NODE_DSN,
    debug: true,
});

// The request handler must be the first middleware on the app
app.use(Sentry.Handlers.requestHandler());

const port = process.argv[2];
if (port === undefined) {
    console.log(`Please specify a port as first argument`);
    process.exit(0);
}

app.get('/test', () => {
    throw new Error('test');
});

// The error handler must be before any other error middleware and after all controllers
app.use(Sentry.Handlers.errorHandler({
    shouldHandleError(error) {
        return true;
    }
}));

app.listen(port);

我们从node ./test.js 3000开始

然后，在不同的窗口中执行wget -- localhost:3000/test，输出如下。

--2021-07-29 14:03:01--  http://localhost:3000/test
Resolving localhost (localhost)... ::1, 127.0.0.1

HTTP request sent, awaiting response... 500 Internal Server Error
2021-07-29 14:03:01 ERROR 500: Internal Server Error.

express服务器的输出如下所示：

在我的例子中，这段代码是正确的，但问题是我是在VPN上的wsl中运行这个脚本，请求正在发送，但是挂起了。从实验上看，在调试模式下尝试发送错误时，Sentry似乎不会记录任何内容，因此您无法从中推断任何内容。

要测试Sentry是否真的发送任何内容，请尝试更简单的版本

const Sentry = require('@sentry/node');
const SENTRY_NODE_DSN = 'the ingest url';
Sentry.init({
    dsn: SENTRY_NODE_DSN,
    debug: true,
});
Sentry.captureException(new Error('test exception'));

如果脚本挂起(不终止)，这意味着对哨兵服务器的http请求没有完成。这可能是由于你方的网络问题造成的。
