如果拉钩网html页面做了调整,需要重新调整代码

代码如下

#/usr/bin/env python3#coding:utf-8import sysimport jsonimport requests"""Usage:        python3 lagou.py  
      
      
       """def get_jobs(pn=1,kw="python"):        url = 'https://www.lagou.com/jobs/positionAjax.json?needAddtionalResult=false'        payload = {
   "first":"false","pn":pn,"kd":kw}        #payload = {'needAddtionalResult':'false'}        rr = requests.post(url,data=payload)        #print(r.json())        jobs_data = rr.json()        #print(jobs_data["content"]["positionResult"]["result"][0])        jobs = jobs_data["content"]["positionResult"]["result"]        for i in jobs:                print("学历：" + i["education"])                print("城市：" + i["city"])        #       print("福利：" + i["companyLabelList"])                print("薪资：" + i["salary"])                print("职位：" + i["positionName"])                print("要求：" + i["positionAdvantage"])                print("经验：" + i["workYear"])                print("链接：" + "https://www.lagou.com/jobs/" + str(i["positionId"]) + ".html")                print()if __name__ == '__main__':        #pn表示页数，kw表示关键词搜索        pn = sys.argv[1]        kw = sys.argv[2]        get_jobs(pn,kw)
