python处理http请求

Ⅰ 如何用python写一个http post请求

用这个：class urllib2.Request(url[, data][, headers][, origin_req_host][, unverifiable])

其中data就是post的内容。
从别的地方找了个例子一看就能懂。

import urllib
import urllib2
url = 'http://umbra.nascom.nasa.gov/cgi-bin/eit-catalog.cgi'
values = {'obs_year':'2011','obs_month':'March',
'obs_day':'8','start_year':'2011'
,'start_month':'March','start_day':'8'
,'start_hour':'All Hours','stop_year':'2011'
,'stop_month':'March','stop_day':'8'
,'stop_hour':'All Hours','xsize':'All'
,'ysize':'All','wave':'all'
,'filter':'all','object':'all'
,'xbin':'all','ybin':'all'
,'highc':'all'}
data = urllib.urlencode(values)
print data
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
print the_page

Ⅱ python 怎么处理http post 的请求参数

import urllib2
import urllib

#定义一个要提交的数据数组(字典)
data = {}
data['username'] = 'zgx030030'
data['password'] = '123456'

#定义post的地址
url = 'http://www.test.com/post/'
post_data = urllib.urlencode(data)

#提交，发送数据
req = urllib2.urlopen(url, post_data)

#获取提交后返回的信息
content = req.read()

以上。

Ⅲ python 什么是http异步请求

http请求为耗时IO操作，如果同步阻塞的话，进程会等待请求完成。
异步的话，进程会发出http请求(请求以后不需要cpu)，然后跳转到别的任务，直到http请求完成，再调回来继续处理得到的http回应。
最经典的例子就是烧水，同步阻塞就是你一直蹲在炉子旁边等待水烧开，而异步是把水壶放在炉子上，等水开了以后茶壶会叫，这时候你听到声音就会回来处理开水～

Ⅳ 使用python的requests库运行http请求，请问如图的报错是什么原因，要怎么解决的

post的参数顺序再检查确认一下，可以使用类似data=data,header=head的方式赋值避免混淆。

Ⅳ python 怎么处理http post 的请求参数

import httplib, urllib
from urlparse import urlparse
def httppost(url, **kwgs):
httpClient = None
conn = urlparse(url)
try:
params = urllib.urlencode(dict(kwgs))
header = {"Content-type": "application/x-www-form-urlencoded","Accept": "text/plain", }
httpClient = httplib.HTTPConnection(conn.netloc, conn.port, timeout=30)httpClient.request("POST", conn.path, params, header)response = httpClient.getresponse()
print response.status
print response.reason
print response.read()
print response.getheaders()
except Exception, e:
print e
finally:
if httpClient:
httpClient.close()

Ⅵ python 怎么处理http post 的请求参数

import httplib, urllib
from urlparse import urlparse

def httppost(url, **kwgs):
httpClient = None
conn = urlparse(url)
try:
params = urllib.urlencode(dict(kwgs))
header = {"Content-type": "application/x-www-form-urlencoded",
"Accept": "text/plain", }

httpClient = httplib.HTTPConnection(conn.netloc, conn.port, timeout=30)
httpClient.request("POST", conn.path, params, header)

response = httpClient.getresponse()
print response.status
print response.reason
print response.read()
print response.getheaders()
except Exception, e:
print e
finally:
if httpClient:
httpClient.close()

Ⅶ python里同时发送多个http请求怎么弄

多个同进的话，使用多线程就可以，也可以使用多进程，多进程可以更好的利用多核CPU的能力。
