ErrorHandler中的Angular 2路径error.stack

发布时间：2020-12-17 17:10:06 所属栏目：安全来源：网络整理

导读：我正在尝试使用stacktrace.js来报告错误,但堆栈跟踪中的路径引用了“ng：///FormModule/MyComponent.ngfactory.js” TypeError: Cannot read property 'push' of undefined at Object.eval [as handleEvent] (ng:///FormModule/MyComponent.ngfactory.js:668

Stacktrace.js找不到捆绑文件及其对应的源映射,因为无法加载此路径

XMLHttpRequest cannot load ng:///FormModule/MyComponent.ngfactory.js. Cross origin requests are only supported for protocol schemes: http,data,chrome,chrome-extension,https.

是否有人使用WebPack,Stacktrace.js并使源地图工作,或者有人知道如何解决这个问题吗？

解决方法

通过将{offline：true}作为第二个参数传递给StackTrace.fromError方法,修复了Angular 6项目中的类似问题,如下所示：

StackTrace.fromError(error,{offline: true}).then(...

正如建议here.
