我们收到阻碍部署的元数据错误。因为它不允许ng生成。以下是配置；然后是完整的错误跟踪。

在localhost:4200中解析。已将包弃用为angular2-qrscanner@0.1.7.它起作用了！！
然而，在作为Azure WebApp托管时，相机拒绝加载。它在Chrome控制台上给出如下错误消息：-
拒绝从'blob:/5c07044f-447c-45a9-979e-458d5e955f8f'加载媒体，因为它违反了以下内容安全策略指令："默认src'unsafe-inline'数据：https:"。请注意，没有显式设置"media-src"，因此使用"default-src"作为回退。
正在处理的解决方案：-Edge和IE没有给出此错误。相机打开但不扫描。我应该切换到另一个二维码扫描仪还是继续使用"angular2二维码扫描仪"。我也在考虑同样的问题。
