//请求函数

                const formData = new FormData();
                uploadFile.forEach(file => {
                  formData.append('fields', file);
                });
                return new Promise(resolve => {
                  api.uploadUsingPOST(formData).then(res => {
                    const newFiles = res.successAttachments.map(value => {
                      return value.downloadUrl;
                    });
                    resolve(newFiles);
                  });
                });
              },
