使用ng- s3 - Upload或任何其他方法将图像url直接上传到文件

<input type="file" (change)="onFileSelected($event)" accept="image/*">
<button (click)="uploadImage()">上传</button>

import { Component } from '@angular/core';
import { NgxS3UploadService } from 'ng-s3-upload';

@Component({
  selector: 'app-upload-image',
  templateUrl: './upload-image.component.html',
  styleUrls: ['./upload-image.component.css']
})
export class UploadImageComponent {
  selectedFile: File;

  constructor(private s3UploadService: NgxS3UploadService) { }

  onFileSelected(event: any) {
    this.selectedFile = event.target.files[0];
  }

  uploadImage() {
    const file = this.selectedFile;
    const folder = 'images'; // 上传到S3存储桶中的文件夹名称

    this.s3UploadService.upload(file, folder).subscribe(
      (url: string) => {
        console.log('图像上传成功，URL：', url);
        // 在这里可以保存URL到数据库或在前端展示
      },
      (error: any) => {
        console.error('图像上传失败：', error);
      }
    );
  }
}
