Ⅰ 如何用python寫一個http post請求
用這個：class urllib2.Request(url[, data][, headers][, origin_req_host][, unverifiable])
其中data就是post的內容。
從別的地方找了個例子一看就能懂。
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 怎麼處理http post 的請求參數
import urllib2
import urllib
#定義一個要提交的數據數組(字典)
data = {}
data['username'] = 'zgx030030'
data['password'] = '123456'
#定義post的地址
url = 'http://www.test.com/post/'
post_data = urllib.urlencode(data)
#提交，發送數據
req = urllib2.urlopen(url, post_data)
#獲取提交後返回的信息
content = req.read()
以上。
Ⅲ python 什麼是http非同步請求
http請求為耗時IO操作，如果同步阻塞的話，進程會等待請求完成。
非同步的話，進程會發出http請求(請求以後不需要cpu)，然後跳轉到別的任務，直到http請求完成，再調回來繼續處理得到的http回應。
最經典的例子就是燒水，同步阻塞就是你一直蹲在爐子旁邊等待水燒開，而非同步是把水壺放在爐子上，等水開了以後茶壺會叫，這時候你聽到聲音就會回來處理開水～
Ⅳ 使用python的requests庫運行http請求，請問如圖的報錯是什麼原因，要怎麼解決的
post的參數順序再檢查確認一下，可以使用類似data=data,header=head的方式賦值避免混淆。
Ⅳ python 怎麼處理http post 的請求參數
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 怎麼處理http post 的請求參數
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里同時發送多個http請求怎麼弄
多個同進的話，使用多線程就可以，也可以使用多進程，多進程可以更好的利用多核CPU的能力。
