APP文件上传与后端代码

安装插件：

import { Camera, Transfer } from 'ionic-native';

TS代码：

  uploadFile(element, callbackType?: any, skip?: string) {
    this.nativeService.showLoading(element.name + '文件正在上传', true);
    const fileTransfer = new Transfer();
    /**
       * 上传文件时携带参数，这个是可选项。
       */
    var options: any;
    var reqUri = GLOBAL_CONST.APP_SERVE_URL + "/bfs/bfs/fileup/appuploadfile";
    options = {
      fileKey: 'files',
      fileName: element.name,
      mimeType: this.getMimeType(element.type),
      params: {
        docID: this.item.docId,
        fileName: element.name,
        fileType: element.fileType,
        takeTime: element.takeTime,
        takeUserId: GLOBAL_CONST.USER_INFO['userID'],
        takeUserName: element.takeUserName,
        takeLongitude: element.takeLongitude,
        takeLatitude: element.takeLatitude
      },

      headers: { sid: GLOBAL_CONST.USER_INFO['token'] }
    }
    
    this.evidenceList.splice(0, 1);
    //第一个参数是文件的路径，第二个参数是服务器的url，第二个参数也可以是encodeURI(reqUri)
    fileTransfer.upload(element.path, reqUri, options).then((data) => {
      alert(JSON.stringify(data));
      let dataValue  = data.response;
      let dataObject: any = JSON.parse(dataValue);
      if(dataObject.success){
        alert(dataObject.fileid);
        this.fileList.push(dataObject.fileid);
      }

      this.nativeService.hideLoading();

      if (this.evidenceList.length == 0) {
          this.submitAddForm();
      }
      for (let idx in this.evidenceList) {
        this.uploadFile(this.evidenceList[idx], callbackType, skip);
        break;
      }

    }, (err) => {
      this.nativeService.hideLoading();

      if (this.evidenceList.length == 0) {
        this.submitAddForm();
      }

      for (let idx in this.evidenceList) {
        this.uploadFile(this.evidenceList[idx], callbackType, skip);
        break;
      }

    });
  }
