Question

我可以将文件传递到文件夹，但是不能将其ID传递给它。我正在使用ng2-file-upload。我正在mat-dialog框内执行此上传操作我在对话框中获取了spf id，但不知道如何将其发送到URL。还有其他方法可以发布带有ID的文件吗？它给this.attachment列表未定义码 html：

<button type="button" (click)="item.upload()"><i class="fa fa-upload" aria-hidden="true"></i></button>

ts：

           import { Component, OnInit, Inject } from '@angular/core';
        import { MatDialogRef, MAT_DIALOG_DATA } from '@angular/material';
        import { Http,Response,Headers } from "@angular/http";
        import { DialogService } from '../dialog.service';
        import { FileSelectDirective, FileUploader} from 'ng2-file-upload';
        import { ActivatedRoute, Router } from '@angular/router';
        import {saveAs} from 'file-saver';


    const uri = 'http://localhost:3000/file/upload/';
    @Component({
      selector: 'app-upload-pdf',
      templateUrl: './upload-pdf.component.html',
      styleUrls: ['./upload-pdf.component.css']
    })

   export class UploadPdfComponent implements OnInit {
  id =""
  url : string ;
  attachmentList : any[];
  uploader: FileUploader;

  constructor(private routes : ActivatedRoute , public dialogRef :MatDialogRef<UploadPdfComponent>,private dialog: DialogService,
    @Inject(MAT_DIALOG_DATA) public data: any)
     {
      this.id = this.data.id;
      this.url = `${uri}/${this.id}`;
      this.uploader =  new FileUploader({url : this.url});
      this.uploader.onCompleteItem = (item:any,response:any,status:any,headers :any)=>{
        this.attachmentList.push(JSON.parse(response));

       }

      } 
  ngOnInit() {

    let body : any = {
      "Spf_id":this.id
      }
    console.log("SPF_id inside upload", body)
  }

    }

您可以在此处使用字符串文字功能。编辑：在构造url字符串后创建对象

 const uri = "http://localhost:3000/file/upload";
        private url: string; 
uploader: FileUploader;
          ngOnInit() {
           this.url: `${uri}/${this.id}`;
           this.uploader = = new FileUploader({url : this.url});
            let body : any = {
              "Spf_id":this.id
              }
            console.log("SPF_id inside upload", body)
          }
