excel在我们日常工作生活中会经常用到,通常我们都是用office软件去编写文档。但是对于格式一致的excel文档,如果还是使用人工完成,那绝不是我们软件工程师的姿态了~
下面我就介绍一种方法,不需要复杂的编程,任何编程语言都可使用~
调用别人封装好的API,只要能发送post请求就行,,,特别适合大规模生成相似文档的应用场合
API调用说明:https://www.xiaocongjisuan.com/show/api/44
API传参注意事项:
- appKey:接口唯一标识,在用户后台->应用中心->我的接口查看
- openId:平台id,注册后系统自动生成,在用户后台->用户中心->账户信息查看
- 表格内容是以json类型的字符串表示,只需要按照一定格式拼接字符串(集体规则查看api说明文档),然后调用api即可。
同时接口说明中也有各种开发语言的调用DEMO,如:java、python、php、c#、golang、nodeJS,其实不止上述这些语言,只要可以发出POST请求,就可以使用该接口,非常的方便。这个平台还有很多其它功能的接口,大部分是免费的。像什么天气预报、万年历、老黄历、中文分词、电影数据查询、电子书查询、网盘数据等等,大家慢慢去发现吧!下面贴一下文档内容提取的相关代码:
