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
