使用 express 进行 Sentry 错误记录不会发送任何错误答案

【问题标题】：Sentry error logging with express does not send any errors使用 express 进行 Sentry 错误记录不会发送任何错误

【问题描述】：

当我尝试将错误发送到简单的 node.js Express 服务器的 Sentry 时，我没有在 Sentry 本身中记录任何错误。没有设置入站过滤器，它不会报告过去 30 天内过滤的任何内容。允许的域设置为*，我认为这是默认设置。我使用的代码或多或少与the documentation 中的示例代码相同。但是，当调用端点时，Sentry 中不会出现任何内容，并且调试行即使发送也不会显示任何有关错误的信息。

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);

我们以node ./test.js 3000开头

然后我们从另一个窗口执行wget -- localhost:3000/test，它会给出以下输出。

--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.

快递服务器的输出是这样的：

【解决方案1】：

在我的情况下，此代码是正确的，但问题是我在 VPN 上的 wsl 中运行此脚本，并且请求正在发送，但挂起。从实验上看，在调试模式下尝试发送错误时，Sentry 似乎没有记录任何内容，因此您无法从中推断出任何内容。

要测试 Sentry 是否确实发送任何内容，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（没有终止），这意味着对哨兵服务器的http请求没有完成。这可能是由于您这边的网络问题。
