      getFileContents: 'getFileContents',

        // 处理获取到的代码
      });

        // 处理获取到的代码
      } catch (err) {
        // 处理错误
      }
    },
  },
}

export default {
  methods: {
    async getFileContents() {
      const module = await import('/path/to/file.js');
      // 处理获取到的代码
    },
  },
}
