使用angular2-logger显示行号和文件名

1-我创建了一个Loggerservice.

2-我将服务导入app.module.ts并将其用作提供者.

3- Loggerservice看起来像这样：

import { Injectable } from '@angular/core';

@Injectable()
export class Loggerservice {
    public error(messagE) {
        try { throw new Error(); } catch (E) {
            console.log(e.stack);
            const stackTraces = e.stack.split('at');
            const fileList = stackTraces[2].substr(
                stackTraces[2].lasTindexOf('/src'),stackTraces[2].length - 1 ).replace(')',''
            );
            const functionName = stackTraces[2].substr(0,stackTraces[2].indexOf('(') - 1);

            // Do whatever you want,use console.log or angular2-logger service
            console.log(messagE);
        }
    }
}
