1、Python requests模块说明
requests是使用Apache2 licensed 许可证的HTTP库。
用python编写。
比urllib2模块更简洁。
Request支持HTTP连接保持和连接池，支持使用cookie保持会话，支持文件上传，支持自动响应内容的编码，支持国际化的URL和POST数据自动编码。
在python内置模块的基础上进行了高度的封装，从而使得python进行网络请求时，变得人性化，使用Requests可以轻而易举的完成浏览器可有的任何操作。
现代，国际化，友好。
requests会自动实现持久连接keep-alive
2、Python requests模块基础入门
1）导入模块
import requests
2）发送请求的简洁
示例代码：获取一个网页（个人github）
import requests
r = requests.get('https://github.com/Ranxf') # 最基本的不带参数的get请求
r1 = requests.get(url='http://dict.baidu.com/s', params={'wd': 'python'}) # 带参数的get请求
我们还可以使用requests模块其它请求方法
1"htmlcode">
> url_params = {'key':'value'} # 字典传递参数，如果值为None的键不会被添加到url中 > r = requests.get('your url',params = url_params) > print(r.url) your url"htmlcode">import requests import json r = requests.post('https://api.github.com/some/endpoint', data=json.dumps({'some': 'data'})) print(r.json())5）定制头和cookie信息
header = {'user-agent': 'my-app/0.0.1''} cookie = {'key':'value'} r = requests.get/post('your url',headers=header,cookies=cookie) data = {'some': 'data'} headers = {'content-type': 'application/json', 'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0'} r = requests.post('https://api.github.com/some/endpoint', data=data, headers=headers) print(r.text)6）响应状态码
使用requests方法后，会返回一个response对象，其存储了服务器响应的内容，如上实例中已经提到的 r.text、r.status_code……
获取文本方式的响应体实例：当你访问 r.text 之时，会使用其响应的文本编码进行解码，并且你可以修改其编码让 r.text 使用自定义的编码进行解码。
r = requests.get('http://www.itwhy.org') print(r.text, '\n{}\n'.format('*'*79), r.encoding) r.encoding = 'GBK' print(r.text, '\n{}\n'.format('*'*79), r.encoding)示例代码：
import requests r = requests.get('https://github.com/Ranxf') # 最基本的不带参数的get请求 print(r.status_code) # 获取返回状态 r1 = requests.get(url='http://dict.baidu.com/s', params={'wd': 'python'}) # 带参数的get请求 print(r1.url) print(r1.text) # 打印解码后的返回数据运行结果：

r = requests.get('url',timeout=1) #设置秒数超时，仅对于连接有效9)会话对象，能够跨请求保持某些参数
s = requests.Session() s.auth = ('auth','passwd') s.headers = {'key':'value'} r = s.get('url') r1 = s.get('url1')10）代理

使用request模块，也可以上传文件，文件的类型会自动进行处理：
import requests url = 'http://127.0.0.1:8080/upload' files = {'file': open('/home/rxf/test.jpg', 'rb')} #files = {'file': ('report.jpg', open('/home/lyb/sjzl.mpg', 'rb'))} #显式的设置文件名 r = requests.post(url, files=files) print(r.text)request更加方便的是，可以把字符串当作文件进行上传：
import requests url = 'http://127.0.0.1:8080/upload' files = {'file': ('test.txt', b'Hello Requests.')} #必需显式的设置文件名 r = requests.post(url, files=files) print(r.text)身份验证
基本身份认证(HTTP Basic Auth)
import requests from requests.auth import HTTPBasicAuth r = requests.get('https://httpbin.org/hidden-basic-auth/user/passwd', auth=HTTPBasicAuth('user', 'passwd')) # r = requests.get('https://httpbin.org/hidden-basic-auth/user/passwd', auth=('user', 'passwd')) # 简写 print(r.json())另一种非常流行的HTTP身份认证形式是摘要式身份认证，Requests对它的支持也是开箱即可用的:
requests.get(URL, auth=HTTPDigestAuth('user', 'pass')Cookies与会话对象
如果某个响应中包含一些Cookie，你可以快速访问它们：
import requests r = requests.get('http://www.google.com.hk/') print(r.cookies['NID']) print(tuple(r.cookies))要想发送你的cookies到服务器，可以使用 cookies 参数：
import requests url = 'http://httpbin.org/cookies' cookies = {'testCookies_1': 'Hello_Python3', 'testCookies_2': 'Hello_Requests'} # 在Cookie Version 0中规定空格、方括号、圆括号、等于号、逗号、双引号、斜杠、问号、@，冒号，分号等特殊符号都不能作为Cookie的内容。 r = requests.get(url, cookies=cookies) print(r.json())会话对象让你能够跨请求保持某些参数，最方便的是在同一个Session实例发出的所有请求之间保持cookies，且这些都是自动处理的，甚是方便。
下面就来一个真正的实例，如下是快盘签到脚本：
import requests headers = {'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'Accept-Encoding': 'gzip, deflate, compress', 'Accept-Language': 'en-us;q=0.5,en;q=0.3', 'Cache-Control': 'max-age=0', 'Connection': 'keep-alive', 'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0'} s = requests.Session() s.headers.update(headers) # s.auth = ('superuser', '123') s.get('https://www.kuaipan.cn/account_login.htm') _URL = 'http://www.kuaipan.cn/index.php' s.post(_URL, params={'ac':'account', 'op':'login'}, data={'username':'****@foxmail.com', 'userpwd':'********', 'isajax':'yes'}) r = s.get(_URL, params={'ac':'zone', 'op':'taskdetail'}) print(r.json()) s.get(_URL, params={'ac':'common', 'op':'usersign'})requests模块抓取网页源码并保存到文件示例
这是一个基本的文件保存操作，但这里有几个值得注意的问题：
1.安装requests包，命令行输入pip install requests即可自动安装。很多人推荐使用requests，自带的urllib.request也可以抓取网页源码
2.open方法encoding参数设为utf-8，否则保存的文件会出现乱码。
3.如果直接在cmd中输出抓取的内容，会提示各种编码错误，所以保存到文件查看。
4.with open方法是更好的写法，可以自动操作完毕后释放资源

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
