web.py

1.安装：

wget http://webpy.org/static/web.py-0.37.tar.gz

tar xvfz web.py-0.37.tar.gz

cd web.py-0.37

sudo python setup.py install

2.需求：

先说下需求，http://10.75.7.237:8080/?ipaddress=10.75.7.29&count=100 ，最终得到这个ip的日志的前100行

3.讲解：

#!/usr/bin/python

import web

render = web.template.render(‘templates/‘) 这是告诉你的web展现页面放在那个位置

urls = (

‘/‘, ‘index‘

)

这是告诉你访问/路径时所调用的类是index

class index:

def reset_sigpipe(self):

signal.signal(signal.SIGPIPE,signal.SIG_DFL)

def GET(self):

ip=web.input(ipaddress=None,count=None)  让url可以传输多个值名为ipaddress和count

print ip[‘ipaddress‘]

print ip[‘count‘]

a=ip[‘ipaddress‘]

address_dict={‘10.13.144.‘:‘bx‘,‘10.73.26.‘:‘tc‘,‘10.75.7.‘:‘yf‘,‘10.67.15.‘:‘yq‘}

aa=a.split(".")

b=aa[0:3]

d=aa[-1]

e=".".join(b)

c=e+"."

address_1=address_dict[c]

f=str(d)

g=address_1+f

time_day=time.strftime(‘%Y-%m-%d‘)

#h_1=subprocess.Popen(‘grep -R %s /data1/saelog/%s/error/‘%(g,time_day),shell=True,preexec_fn=self.reset_sigpipe(),stdout=subprocess.PIPE)

#h=h_1.stdout.read()

h = os.popen(‘grep -R %s /data1/saelog/%s/error/‘ % (g,time_day))

print h

head_list=[]

sum=0

dict={}

head_lines=ip[‘count‘]

print head_lines

if head_lines:

for i in h:

j=i.split(":")[1:]

head_list.append(j)

for kk in head_list:

dict[sum]=head_list[sum]

sum+=1

if sum == int(head_lines):

break;

dict_json=json.dumps(dict)

else:

for i in h:

j=i.split(":")[1:]

head_list.append(j)

for kk in head_list:

dict[sum]=head_list[sum]

sum+=1

dict_json=json.dumps(dict)

print dict_json

return render.index(dict_json)       传给页面展示的值

#return "Hello, world!"

if __name__ == "__main__":

app = web.application(urls, globals())

app.run()

templates目录下

index.html

$def with (name)

$if name:

$name    name为代码传过来的值

4.启动web.py

python test.py  后面不跟端口默认就是8080

5.访问http://10.75.7.237:8080/?ipaddress=10.75.7.29&count=100
