javascript - 如何使用Angular加载PDF文件(How to load pdf file with angular)

Question

Am having troubles loading the pdf file and sending it the api (backend)

(加载pdf文件并发送api（后端）时遇到麻烦)

 getFileUrl(event) { var file = event.target.files[0]; var myReader: FileReader = new FileReader(); myReader.onloadend = (e) => { let res = myReader.result; let formData = new FormData(); formData.append("formFile", file); } myReader.readAsArrayBuffer(file); } 

 <input type="file" hidden #fileUpload (change)="getFileUrl($event)" /> <mat-icon (click)="fileUpload.click()"> attach_file </mat-icon>
