python访问网站可以用标准模块--urllib模块(这里省略),和requests(安装-pip install requests)模块,requests模块是在urllib的基础上进行的封装,比urllib模块功能更强到,易用
import json,requests #发送get请求 url = ‘http://api.nnzhp.cn/api/user/stu_info?stu_name=小黑马‘ req = requests.get(url) #发送get请求 print(req.text) #获取结果,返回string/html等用text print(req.json()) #获取结果直接就是字典,等价于 print(json.loads(req.text)) #json串转化成字典,注:返回的必须是json串,才能用.json方法。 #发送post请求 url = ‘http://api.nnzhp.cn/api/user/login‘ data = {‘username‘:‘niuhanyang‘,‘passwd‘:‘aA123456‘} req = requests.post(url,data) #发送post请求,第一个参数是url,第二个参数是请求参数 print(req.json()) #入参是json的 url = ‘http://api.nnzhp.cn/api/user/add_stu‘ data = {‘name‘:‘丁飞‘,‘grade‘:‘巨蟹座‘,‘phone‘:31971891223} req = requests.post(url,json=data) #发送post请求,第一个参数是url,第二个参数是请求参数 print(req.json()) #添加cookie url = ‘http://api.nnzhp.cn/api/user/gold_add‘ data = {‘stu_id‘:231,‘gold‘:1000} cookie = {‘niuhanyang‘:‘6d195100b95a43046d2e385835c6e2c2‘} req = requests.post(url,data,cookies=cookie) print(req.json()) #添加header url=‘http://api.nnzhp.cn/api/user/all_stu‘ h = {‘Referer‘:‘http://api.nnzhp.cn/‘,‘User-Agent‘:‘Chore‘}#可以添加多个header,用,分开 res = requests.get(url,headers=h) print(res.json()) #上传文件 url = ‘http://api.nnzhp.cn/api/file/file_upload‘ f = open(r‘C:\Users\bjniuhanyang\Desktop\ad.cpm.schedulingInfo.v1.json‘,‘rb‘) r = requests.post(url,files={‘file‘:f}) print(r.json()) #下载文件 url= ‘http://www.besttest.cn/data/upload/201710/f_36b1c59ecf3b8ff5b0acaf2ea42bafe0.jpg‘ r = requests.get(url) print(r.status_code) #获取请求的状态码 print(r.content) #获取返回结果--二进制格式的 fw = open(r‘bt.jpg‘,‘wb‘) fw.write(r.content) fw.close() #保存网页 url = ‘http://www.nnzhp.cn/archives/630‘ r = requests.get(url) f = open(‘nnzhp.html‘,‘wb‘) f.write(r.content) f.close()
