上传文件时如何通过 ng2-file-upload 发送其他参数

Question

我创建了两个选择，并希望在上传期间将它们的值作为参数发送到后端。你知道怎么做吗？你能帮帮我吗？

我的代码：

// Select Forms
 // Month form
    this.sendMonthsForm = this.fb.group({
      monthsValue: [null]
    });
    // Year form
    this.sendYearsForm = this.fb.group({
      yearsValue: [null]
    });

// Upload
  this.uploader = new FileUploader({
        url: `${environment.baseUrl}/upload?title=SuSa&context=${year}&period=${month}`,
        maxFileSize: 2 * 1024 * 1024,
        allowedFileType: ['csv', 'xls', 'xlsx'],
        authToken: `Bearer ${currentUser.auth_token}`,
      });

Answer 1

uploader: FileUploader = new FileUploader({
  url: URL,
  headers: [{ name: 'Authorization', value: 'Bearer ejy...' }]
});

Answer 2

this.uploader = new FileUploader({
        url: `${environment.baseUrl}/upload?title=SuSa&context=${year}&period=${month}`,
        maxFileSize: 2 * 1024 * 1024,
        additionalParameter:{uploaderparams1:'its-value',uploaderparams2:'its-value'},
        allowedFileType: ['csv', 'xls', 'xlsx'],
        authToken: `Bearer ${currentUser.auth_token}`,
      });
