一些基本用法，ssl證書和身份認證是尚未驗證的?

            
              import requests

headers = {
    'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)'
                   ' AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36',
    # 'Cookie' : 'XXXXXXXXXXXXXXXX'
}

# 取得圖片
# res = requests.get("https://pic2.zhimg.com/d3dd87a0feae0a3db82973157eee89c0_m.jpg", headers=headers)
# with open("1.jpg", "wb") as pic:
#     pic.write(res.content)
# print(res.content)

# 測試cookies,知乎取不到cookies，其他網站可以
# res = requests.get("https://www.zhihu.com", headers=headers)
# print(res.cookies)
# for key, value in res.cookies.items() :
#     print(key+"="+value)

# 測試session, 兩次的cookies值是一致的，證明維持了同一個會話
# session = requests.Session()
# res1 = session.get("http://httpbin.org/cookies/set/number/1234567")
# print(res1.text)
# res2 = session.get("http://httpbin.org/cookies")
# print(res2.text)

# 測試ssl證書, 沒有找到合適的網站，12306的證書已經被修改好了
# session = requests.Session()
# res = session.get("https://www.ccb.com/cn/home/indexv3.html/", verify=False)
# print(res.status_code)

# 測試超時設置
# session = requests.Session()
# 如果你設置了一個單一的值作為 timeout，這一timeout值將會用作connect和read二者的總和timeout：
#res = session.get("https://www.baidu.com", timeout=1)
#如果要分別指定，就傳入一個元組：
# res = session.get("https://www.baidu.com", timeout=(0.1, 3))
# print(res.status_code)

# 身份認證,這種簡單的方法無效，總是返回 status_code=200
# res = requests.get("https://passport.csdn.net/login?code=public", auth=('17671766710', 'ylbs4342017'))
# print(res.status_code)
