//请求url获取响应信息
    Connection.Response res = con.ignoreContentType(true).method(Connection.Method.POST).execute();

请求的时候已经设置了 post
查找到是

请求的之后 302转发成了get 请求而req的 body还在其中

所以造成
Exception in thread "main" java.lang.IllegalArgumentException: Cannot set a request body for HTTP method GET

Answer 1

能不能试试Jsoup.connect(url).timeout(120000).followRedirects(true).execute().parse();设置不跟随跳转或者跟随跳转呢？
此外，可以搜索JSoup请求跳转302之类的问题。多尝试看看。
