我的要求是在输入框中显示选定的值，并将选定的 Id 和值获取到 .ts 文件中。因为我需要 Id 和 Value，所以我将选项值直接绑定到 [value]。但是如果我这样做，它就会被打印为 [Object Object]。

<mat-form-field appearance="outline" class="w-100">
            <mat-label>Enter Hotel Name</mat-label>
            <input type="text" aria-label="Number" matInput [formControl]="myControl" [matAutocomplete]="auto">
            <mat-autocomplete #auto="matAutocomplete" (optionSelected)="selectedclient($event)">
                <mat-option *ngFor="let option of clients; let i = index" [value]="option">
                    {{ option.name }}
                  </mat-option>
            </mat-autocomplete>
            <mat-icon matSuffix>location_on</mat-icon>
          </mat-form-field>

Ts文件

    options = [
        { id: 1, name: 'One'},
        { id: 2, name: 'Two'},
        { id: 3, name: 'Three'}
       ];

selectedclient(event) {
     console.log(event.option.value);
   }

我正在按照本教程将文件从 php 上传到亚马逊 s3。教程很好，但是我有一个小问题，所有上传的文件都必须手动公开才能从互联网上看到它们。有没有办法自动化这个？
