Question

在我的项目中，我从Amazon获取文件。文件始终会从Amazon成功上载，但不会始终显示，并且在控制台中未显示时，我会看到此警告

Warning: Name token is longer than allowed by the spec: 148
Warning: Name token is longer than allowed by the spec: 204
Warning: Name token is longer than allowed by the spec: 148
Warning: Indexing all PDF objects

代码看起来像这样

      <div class="files-list">
        <div class="row">
          <div class="col-md-2" *ngFor="let file of files">
            <div class="thumbnail">
              <pdf-viewer *ngIf="file['file_path']"
                          [page]="1"
                          [src]="file['file_path']"
                          [show-all]="false"
                          [original-size]="false"
                          [show-borders]="true"
                          style="display: block; height: 210px"
              ></pdf-viewer>
              <span class="file-name" *ngIf="file.type === 'application/pdf'">{{ file?.name }}</span>
              <span class="file-name" *ngIf="file.type !== 'application/pdf'">{{ file?.name.slice(11) }}</span>
            </div>
            <br>
          </div>
        </div>
      </div>

我不明白为什么有时显示文件，有时却不显示，如果我提供的不是静态网址，那么文件总是显示为 file ['file_path'] 。谁能证明我做得不好，请先谢谢。
