python urllib2使用心得

1、http GET请求

过程：获取返回结果，关闭连接，打印结果

f = urllib2.urlopen(req, timeout=10)

the_page = f.read()

f.close()
print the_page

2、http GET请求 + 包头

paras = "Token=1234567890;Uuid=0987654321"

send_headers = {"Cookie": paras, "User-Agent": "mixh5monitor", "Content-Type": "application/json"}

req = urllib2.Request(url, headers=send_headers)  # 包头
f = urllib2.urlopen(req, timeout=10)  # 包体

the_page = f.read()

f.close()
print the_page

3、http GET请求 + 包头，处理返回响应包头

paras = "Token=1234567890;Uuid=0987654321"

send_headers = {"Cookie": paras, "User-Agent": "mixh5monitor", "Content-Type": "application/json"}

req = urllib2.Request(url, headers=send_headers)  # 包头
f = urllib2.urlopen(req, timeout=10)  # 包体

response_head = f.info().getheader("Content-Type")  # 获取返回包头中Content-Type内容

print response_head

f.close()

4、http POST请求

postdata = urllib.urlencode({"username": "test", "password": "123456", "type": "Z"})

f = opener.open(url, postdata, timeout=10)

the_page = f.read()

f.close()
print the_page

5、http POST请求 + 包头

postdata = urllib.urlencode({"username": "test", "password": "123456", "type": "Z"})

paras = "Token=1234567890;Uuid=0987654321"

send_headers = {"Cookie": paras, "User-Agent": "mixh5monitor", "Content-Type": "application/json"}

req = urllib2.Request(url, headers=send_headers)  # 包头
f = opener.open(req, postdata, timeout=10)
the_page = f.read()
f.close()
print the_page

6、http POST请求 + 包头，处理返回响应包头

postdata = urllib.urlencode({"username": "test", "password": "123456", "type": "Z"})

paras = "Token=1234567890;Uuid=0987654321"

send_headers = {"Cookie": paras, "User-Agent": "mixh5monitor", "Content-Type": "application/json"}

req = urllib2.Request(url, headers=send_headers)  # 包头
f = opener.open(req, postdata, timeout=10)

response_head = f.info().getheader("Cookie")  # 获取返回包头中Cookie内容

print response_head
f.close()
