Groovy

import groovy.json.JsonSlurper
import org.cyberneko.html.parsers.SAXParser
def ResponseMessage = messageExchange.response.responseContent
def object = new JsonSlurper().parseText(ResponseMessage)
def html = object.value[0].body.content
log.info "HTML 1 : " + html //here I am getting html page.
def content = new XmlSlurper( new SAXParser() ).parse( html ) //getting error at this line

我想要 href 中的键值

键：GBsG3gBoI4YV+fSfejXCbw6vgG6m4OCU7Czfn3PAKXtxVI9Ex

Answer 1

最近我使用类似的基于正则表达式的代码来进行简单的网络爬虫：

def content = "<lotsoftags..><a href=\"https://abc.xyz123.com?key=GBsG3gBoI4YV+fSfejXCbw6vgG6m4OCU7Czfn3PAKXtxVI9Ex\" style=\"font-family:'Source Sans Pro',sans-serif; font-weight:400; font-size:18pt;\"<lotsoftags..>"

def keys = ( content =~ /<a href="[^"]+[?&]?key=([\w+]+)&?[^"]*"/ ).findAll()*.last()

assert keys[ 0 ] == 'GBsG3gBoI4YV+fSfejXCbw6vgG6m4OCU7Czfn3PAKXtxVI9Ex'
