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())+"
") 
print(req.json())

#入参是json
# url = 'http://api.nnzhp.cn/api/user/add_stu'
