如何用哨兵报告console.error?

How to report console.error with Sentry?

我的应用程序 console.error 报告了一些严重问题,但 thrown 没有,因此应用程序可能会继续 运行 - 可能处于瘫痪状态。

也有必要报告 console.error 问题,但是 Sentry (Raven) 库发送到服务器只抛出异常。

有人知道如何很好地解决这个问题吗?

(理想情况下无需重写所有 console.error 调用,因为某些供应商库可能仍将输出写入控制台)

找到了一个有点 hacky 的解决方案:

const consoleError = console.error;
console.error = function(firstParam) {
  const response = consoleError.apply(console, arguments);
  Raven.captureException(firstParam, { level: 'error' });
  return response;
};

它只是包装 console.error 并将控制台中的每个错误日志报告给 Raven(哨兵)。

如果有人有更好的方法(也许是 Sentry 的一些隐藏功能),请随时分享!

这是一个更强大的覆盖解决方案

// creating function declarations for better stacktraces (otherwise they'd be anonymous function expressions)
var oldConsoleError = console.error;
console.error = reportingConsoleError; // defined via function hoisting
function reportingConsoleError() {
  var args = Array.prototype.slice.call(arguments);
  Sentry.captureException(reduceConsoleArgs(args), { level: 'error' });
  return oldConsoleError.apply(console, args);
};

var oldConsoleWarn = console.warn;
console.warn = reportingConsoleWarn; // defined via function hoisting
function reportingConsoleWarn() {
  var args = Array.prototype.slice.call(arguments);
  Sentry.captureMessage(reduceConsoleArgs(args), { level: 'warning' });
  return oldConsoleWarn.apply(console, args);
}

function reduceConsoleArgs(args) {
  let errorMsg = args[0];
  // Make sure errorMsg is either an error or string.
  // It's therefore best to pass in new Error('msg') instead of just 'msg' since
  // that'll give you a stack trace leading up to the creation of that new Error
  // whereas if you just pass in a plain string 'msg', the stack trace will include
  // reportingConsoleError and reportingConsoleCall
  if (!(errorMsg instanceof Error)) {
    // stringify all args as a new Error (which creates a stack trace)
    errorMsg = new Error(
      args.reduce(function(accumulator, currentValue) {
        return accumulator.toString() + ' ' + currentValue.toString();
      }, '')
    );
  }
  return errorMsg;
}

正如用户@kumar303 在他对问题的评论中提到的...您可以使用 JS 控制台集成 Sentry.Integrations.CaptureConsole

有关文档,请参阅 https://docs.sentry.io/platforms/javascript/configuration/integrations/plugin/#captureconsole

最后,您设置 Sentry 的 JS 代码如下所示:

import * as Sentry from '@sentry/browser';
import { CaptureConsole } from '@sentry/integrations';

Sentry.init({
  dsn: 'https://your-sentry-server-dsn',
  integrations: [
    new CaptureConsole({
      levels: ['error']
    })
  ],
  release: '1.0.0',
  environment: 'prod',
  maxBreadcrumbs: 50
})

如果有人呼叫 console.error 一个新事件将发送到哨兵。

根据@Marc Schmid 的解决方案,如果您 link 到 Sentry CDN 文件,我想出了以下工作示例。

<script src="https://browser.sentry-cdn.com/5.11.1/bundle.min.js" integrity="sha384-r7/ZcDRYpWjCNXLUKk3iuyyyEcDJ+o+3M5CqXP5GUGODYbolXewNHAZLYSJ3ZHcV" crossorigin="anonymous"></script>

<script src="https://browser.sentry-cdn.com/5.11.1/captureconsole.min.js"></script>
<script>
    Sentry.init({
        dsn: 'https://abcdef1234567890@sentry.io/012345',
        debug: false,
        integrations: [
            new Sentry.Integrations.CaptureConsole({
                levels: ['error']
            })
        ],
    });
</script>

我使用您的 Sentry 实例编写了一个库。 https://github.com/aneldev/dyna-sentry
