===== 问题集 =====

**问题一：404报错**

Angular 刷新页面的时候出现 404 错误。有两个解决方案, <color #ed1c24>方法二测试有效</color>
<code | 方案一>
import { LocationStrategy, HashLocationStrategy } from '@angular/common';
@NgModule({
  providers: [
    { provide: LocationStrategy, useClass: HashLocationStrategy }
  ]
})
</code>

<code | 方法二>
imports: [RouterModule.forRoot(routes), RouterModule.forRoot(routes, {useHash: true})],
</code>

**问题二：运行时出错**
以下代码在 ng serve 时没有问题，但 ng build 并推送到服务器之后就出现运行时错误。

<code | download>
if(options?.headers !== null){
  (options?.headers as any).Authorization = `Bearer ${BaseSetting.AccessToken}`
}
</code>

需要更改为
<code | download>
var hd:any = options?.headers
hd.Authorization = `Bearer ${BaseSetting.AccessToken}`
</code>
