Import requestsurl= "https://www.baidu.com/s" headers={' user-agent ': "mozilla/5.0 (X11; Linux x86_64) applewebkit/537.36 (khtml, like Gecko) chrome/53.0.2785.143 safari/537.36 "}post_data={' username ':" Qujun "," passwd ":" Xixi "}parameters={' WD ':" ABC "} #提交get请求P_get =request.get (url,params=parameters) #提交post请求P_post = Reuests.post (Url,headers=headers,data=post_data)
