#req = requests.get(url)# 发送请求
#print(req.text)# 得到的是json格式
#print(req.json)# 得到的是字典格式
#print(type(req.text))
#print(type(req.json))

#发送post请求,登录并将个人信息保存到本地
url = "https://api.apiopen.top/developerLogin"
data = {'name':'xxx','passwd':'xxx'}
req = requests.post(url,data)#发送post请求，第一个参数是URL，第二个参数是请求数据
filename = 'D:/write_data.txt'
with open(filename,'w') as f:
    f.write(str(req.json())+"\n")
print(req.json())

#入参是json
# url = 'http://api.nnzhp.cn/api/user/add_stu'
# data = {'name':'mapeipei','grade':'Mp123456','phone':15601301234}

# print(req.json())

#添加header
# url = 'http://api.nnzhp.cn/api/user/all_stu'

# res = requests.get(url,headers=header)
# print(res.json())

# 添加cookie
# url = 'http://api.nnzhp.cn/api/user/gold_add'

# r = requests.get(url)
# print(r.status_code)#获取请求的状态码
# print(r.content)#获取返回结果的二进制格式
# fw = open('mpp.jpg','wb')
# fw.write(r.content)
# fw.close()
