响应函数python 响应函数英文( 三 )


#发送事件
self.__eventManager.SendEvent(event)
print u'公众号发送新文章\n'
#监听器 订阅者
class Listener:
def __init__(self,username):
self.__username = username
#监听器的处理函数 读文章
def ReadArtical(self,event):
print(u'%s 收到新文章' % self.__username)
print(u'正在阅读新文章内容:%s'% event.dict["artical"])
"""测试函数"""
#--------------------------------------------------------------------
def test():
listner1 = Listener("thinkroom") #订阅者1
listner2 = Listener("steve")#订阅者2
eventManager = EventManager()
#绑定事件和监听器响应函数(新文章)
eventManager.AddEventListener(EVENT_ARTICAL, listner1.ReadArtical)
eventManager.AddEventListener(EVENT_ARTICAL, listner2.ReadArtical)
eventManager.Start()
publicAcc = PublicAccounts(eventManager)
timer = Timer(2, publicAcc.WriteNewArtical)
timer.start()
if __name__ == '__main__':
test()
python 已知响应函数求单位阶跃响应或脉冲响应最近学习自动控制原理响应函数python,关于控制系统的一些响应函数python,老师用布置响应函数python了一些作业说要用matlab画,响应函数python我试试python
1.control库:用来计算脉冲响应与阶跃响应
2.sympy:用以化简多项式为和的形式方便写参数
比如我们使用 sympy 来验证等式:x2+y2=(x+(2xy)1/2+y)(x?(2xy)1/2+y)
参照详细例子:
3.matplotlib用以画图
分别是单位脉冲响应和单位节约响应的图像

python怎么响应后端发送get,post请求的接口测试用CGI,名字为test.py,放在apache的cgi-bin目录下:
#!/usr/bin/Python
import cgi
def main():
print "Content-type: text/html\n"
form = cgi.FieldStorage()
if form.has_key("ServiceCode") and form["ServiceCode"].value != "":
print "h1 Hello",form["ServiceCode"].value,"/h1"
else:
print "h1 Error! Please enter first name./h1"
main()
python发送post和get请求
get请求:
使用get方式时,请求数据直接放在url中 。
方法一、
import urllib
import urllib2
url = ""
req = urllib2.Request(url)
print req
res_data = https://www.04ip.com/post/urllib2.urlopen(req)
res = res_data.read()
print res
方法二、
import httplib
url = ""
conn = httplib.HTTPConnection("192.168.81.16")
conn.request(method="GET",url=url)
response = conn.getresponse()
res= response.read()
print res
post请求:
使用post方式时,数据放在data或者body中,不能放在url中,放在url中将被忽略 。
方法一、
import urllib
import urllib2
test_data = https://www.04ip.com/post/{'ServiceCode':'aaaa','b':'bbbbb'}
test_data_urlencode = urllib.urlencode(test_data)
requrl = ""
req = urllib2.Request(url = requrl,data =https://www.04ip.com/post/test_data_urlencode)
print req
res_data = https://www.04ip.com/post/urllib2.urlopen(req)
res = res_data.read()
print res
方法二、
import urllib
import httplib
test_data = https://www.04ip.com/post/{'ServiceCode':'aaaa','b':'bbbbb'}
test_data_urlencode = urllib.urlencode(test_data)
requrl = ""
headerdata = https://www.04ip.com/post/{"Host":"192.168.81.16"}
conn = httplib.HTTPConnection("192.168.81.16")
conn.request(method="POST",url=requrl,body=test_data_urlencode,headers = headerdata)
response = conn.getresponse()
res= response.read()
print res
对python中json的使用不清楚,所以临时使用了urllib.urlencode(test_data)方法;
模块urllib,urllib2,httplib的区别
httplib实现了http和https的客户端协议,但是在python中 , 模块urllib和urllib2对httplib进行了更上层的封装 。
