前言

发送post的请求参考例子很简单，实际遇到的情况却是很复杂的，首先第一个post请求肯定是登录了，但登录是最难处理的。登录问题解决了，后面都简单了。

一、查看官方文档

1.学习一个新的模块，其实不用去百度什么的，直接用help函数就能查看相关注释和案例内容。

>>import requests

>>help(requests)

2.查看python发送get和post请求的案例

 >>> import requests        >>> r = requests.get(‘https://www.python.org‘)        >>> r.status_code        200        >>> ‘Python is a programming language‘ in r.content        True          ... or POST:             >>> payload = dict(key1=‘value1‘, key2=‘value2‘)        >>> r = requests.post(‘http://httpbin.org/post‘, data=payload)        >>> print(r.text)        {          ...          "form": {            "key2": "value2",            "key1": "value1"          },          ...        }

二、发送post请求

1.用上面给的案例，做个简单修改，发个post请求

2.payload参数是字典类型，传到如下图的form里

三、json

1.post的body是json类型，也可以用json参数传入。

2.先导入json模块，用dumps方法转化成json格式。

3.返回结果，传到data里

四、headers

1.以禅道登录为例，模拟登陆，这里需添加请求头headers,可以用fiddler抓包

2.讲请求头写成字典格式

headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0",             "Accept": "application/json, text/javascript, */*; q=0.01",             "Accept-Language": "zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3",             "Accept-Encoding": "gzip, deflate, br",             "Content-Type": "application/json; charset=utf-8",             "X-Requested-With": "XMLHttpRequest",             "Cookie": "xxx.............",    # 此处cookie省略了             "Connection": "keep-alive"             }

五、禅道登录参考代码

# coding:utf-8 # coding:utf-8 import requests # 禅道host地址 host = "http://127.0.0.1"
def login(s,username,psw):     url = host+"/zentao/user-login.html"
    h = {         "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0",         "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",         "Accept-Language": "zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3",         "Accept-Encoding": "gzip, deflate",         "Referer": host+"/zentao/user-login.html",         # "Cookie":  # 头部没登录前不用传cookie，因为这里cookie就是保持登录的         "Connection": "keep-alive",         "Content-Type": "application/x-www-form-urlencoded",         }
    body1 = {"account": username,              "password": psw,              "keepLogin[]": "on",              "referer":  host+"/zentao/my/"             }
    # s = requests.session()   不要写死session
    r1 = s.post(url, data=body1, headers=h)     # return r1.content  # python2的return这个     return r1.content.decode("utf-8")  # python3
def is_login_sucess(res):         if "登录失败，请检查您的用户名或密码是否填写正确。" in res:                 return False         elif "parent.location=" in res:                 return True         else:                 return False
if __name__ == "__main__":     s = requests.session()     a = login(s, "admin", "e10adc3949ba59abbe56e057f20f883e")     result = is_login_sucess(a)     print("测试结果：%s"%result)
