用python实现调用百度图片搜索的API
前言：这段代码是一个简单的图片爬虫程序
它可以通过输入关键词，在百度图片中搜索相关图片，并返回一张随机的图片。
代码使用Flask框架搭建了一个简单的Web应用，将用户输入的关键词作为参数传递给爬虫程序，然后从百度图片中获取相关图片的URL
并随机选择一张返回给用户。用户可以通过访问Web应用的首页，在输入框中输入关键词进行搜索。如果找到相关图片，则会跳转到图片的URL
如果未找到图片，则会显示无法正常查找的提示信息。
应用场景：
将代码发布到服务器上，就可以用markdown格式
!服务器域名/?word=关键字
来显示搜索的图片。
特别是部署了gpt-web的大佬，可以用角色仓库的方式来实现调用百度图片的api来搜图
