爬虫－python调用百度API／requests

from urllib.request import urlopen

import requests

import json

url = "http://apis.baidu.com/txapi/mvtp/meinv" #API

req = requests.get(url) #request.get(url,param=param,headers = headers)

headers= {'apikey':'自己的apikey'} #自己的apikey

params = {'num':'5'} #请求参数(urlParam) :

r = requests.get(url,params=params,headers=headers)

print(r)

def SaveImage(ImageUrl,ImgName= 'default.jpg'):

response = requests.get(ImageUrl,stream = True)

image = response.content

dst = '/Users/Alan/desktop/BaiDUImages/' #路径

path = dst+ImgName

print('Save the file:',path)

with open(path,'wb') as img:

img.write(image)

def run():

for line in r['newslist']:

title = line['title']

picUrl = line['picUrl']

SaveImage(picUrl,ImgName=title+'.jpg')

run()

第二课：

#!/usr/bin/env python3

#antuor:Alan

import requests

import re

headers = {'User-Agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.86 Safari/537.36'}

#审查元素，network 里的request headers,复制过来，变成字典形式url = 'http://www.cnblogs.com/wupeiqi/articles/4938499.html'

html = requests.get(url,headers = headers)

title = re.findall('href="(.*?)</a>',html.text) #查找所有以href="开头＋</a>结尾的内容for i in title:　　print(i)

输入结果：
