# 获取响应对象中的内容是str格式 text # 获取响应对象中的内容是二进制格式的 content # 获取响应状态码 status_code # 获取响应头信息 headers # 获取请求的url url |
import requests url = "https://www.cnblogs.com/songzhixue/p/10717975.html" # 获得一个响应对象 response = requests.get(url=url) # 调用响应对象中的text属性获取请求结果为字符串形式 print(response.text)
带参数的get请求
方式一:
import requests url = "http://www.baidu.com/s?wd=周杰伦" # requests模块可以自动将url中的汉字进行转码 response = requests.get(url).text with open("./zhou.html","w",encoding="utf-8") as fp: fp.write(response)
方式二:
将参数以字典的形式传给params参数
import requests choice = input("请输入搜索条件>>>:").strip() params = { "wd":choice } # https://www.baidu.com/s?wd=周杰伦 url = "http://www.baidu.com/s?" # 带参数的get请求 response = requests.get(url,params) # 获取响应状态码 response.status_code
添加请求头信息
请求头以字典的方式传给headers参数
import requests choice = input("请输入搜索条件>>>:").strip() params = { "wd":choice } # https://www.baidu.com/s?wd=周杰伦 url = "http://www.baidu.com/s?" # 封装请求头信息 headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36' } # 带参数的get请求 response = requests.get(url,params,headers=headers) # 获取响应状态码 response.status_code

基于Ajax的get请求
### 抓取豆瓣影评### import json import requests # url = "https://movie.douban.com/j/search_subjects?type=movie&tag=%E7%83%AD%E9%97%A8&sort=recommend&page_limit=20&page_start=20" # 获取ajax的请求网址(基于ajax的get请求) url = 'https://movie.douban.com/j/search_subjects?' # 自定义请求头 headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36', } # 构建请求参数 params = { 'type': 'movie', 'tag': '热门', 'sort': 'recommend', 'page_limit': '100', # 显示多少数据 'page_start': '1', # 从第几页开始显示 } # 请求目标url response = requests.get(url=url,params=params,headers=headers) # 拿到响应数据,json格式的字符串 json_str = response.text # 对响应数据反序列化得到字典 code = json.loads(json_str) # 在字典中取出想要的数据 for dic in code["subjects"]: rate = dic["rate"] title = dic["title"] print(title,rate)
基于Ajax的post请求
### 抓取肯德基餐厅位置信息### import json import requests url = 'http://www.kfc.com.cn/kfccda/ashx/GetStoreList.ashx?op=keyword' data = { 'cname': '', 'pid': '', 'keyword': '上海',# 查询城市 'pageIndex':'1', # 显示第几页的数据 'pageSize': '10', # 一页显示多少数据 } headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.100 Safari/537.36' } response = requests.post(url=url,data=data,headers=headers) response.text
