如何抓取微信小程序,其实小程序的抓取不是很难,主要解决抓包和如何调试小程序这两个问题。可以采用chrome进行抓取,方便很多。 如果微信小程序抓包抓不到,可能是由于微信版本太高了导致无法抓包。如果版本过高可以采用Fiddler或Charles抓包,这样就能解决抓包问题 只要抓包搞定了,很多小程序也就能抓取了,剩下就是解决IP问题。还有一部分小程序在前端有反爬措施,对请求参数加密或混淆了,这时候需要解决小程序的调试方案了。 微信小程序就相当于一个网站,只不过不能通过浏览器打开。其实浏览器和小程序的构成差不多,小程序里的数据交互也是由javascript来负责的。所以爬虫调试小程序也主要是调试javascript。 我们可以通过代码来进行调试: [JavaScript] 纯文本查看 复制代码 import org.apache.commons.httpclient.Credentials;
