nodejs下载URL地址的文件后保存以及删除指定文件夹的操作

这里下载文件用了axios去下载

下载：

public async download_from(url, fileName) {
    return new Promise(async (resolve, reject) => {
      const download_dir = path.join(
        process.cwd(),
        AppConfig.config.download_file_path,
        this._job_id
      );
      const local_path = path.join(download_dir, fileName);
      //下载文件到指定的文件夹路径下，如果没有的话就创建一下
      if (!fs.existsSync(download_dir)) {
        fs.mkdirSync(download_dir, { recursive: true });
      }
      const fileWriter = fs.createWriteStream(local_path);
      console.log(`文件：${local_path}开始下载，地址是：${url}`);
      try {
        const response = await axios.get(url, { responseType: "stream" });
        if (response.status === 200) {
          response.data.pipe(fileWriter);
          fileWriter.on("finish", () => {
            console.log(`文件：${local_path}下载完成`);
            fileWriter.close();
            resolve(local_path);
          });
        } else {
          console.log(`文件：${local_path}下载出错：${response}`);
          reject(`Error: ${response}`);
        }
      } catch (error) {
        console.log(`文件：${local_path}下载异常：${error}`);
        reject(`Error: ${error}`);
      }
    });
  }

删除文件夹:

/**
   * 这里场景是可能你需要下载后上传到某个目录，然后删除这个下载文件存储的临时文件夹，
   * @param download_file_path 下载后存储的地址
   */
  public del_local_file(download_file_path) {
    try {
      //本次任务下载的文件夹
      const download_dir = path.join(
        process.cwd(),
        download_file_path,
        this._job_id
      );
      //下载上传后删除服务上的临时文件夹
      fs.rmdir(download_dir, { recursive: true }, (err) => {
        if (err) {
          Logger.INSTANCE.error("Error removing folder:", err);
          throw err;
        } else {
          Logger.INSTANCE.info("Folder removed successfully", download_dir);
        }
      });
    } catch (error) {
      Logger.INSTANCE.error("del_local_file_error:", error);
      throw error;
    }
  }
