本文實例講述了Python實現基于HTTP文件傳輸的方法。分享給大家供大家參考。具體實現方法如下：
一、問題：
因為需要最近看了一下通過POST請求傳輸文件的內容 并且自己寫了Server和Client實現了一個簡單的機遇HTTP的文件傳輸工具
二、實現代碼：
Server端:
復制代碼
代碼如下:
#coding=utf-8
from BaseHTTPServer import BaseHTTPRequestHandler
import cgi
class?? PostHandler(BaseHTTPRequestHandler):
??? def do_POST(self):
??????? form = cgi.FieldStorage(
??????????? fp=self.rfile,
??????????? headers=self.headers,
??????????? environ={'REQUEST_METHOD':'POST',
???????????????????? 'CONTENT_TYPE':self.headers['Content-Type'],
???????????????????? }
??????? )
??????? self.send_response(200)
??????? self.end_headers()
??????? self.wfile.write('Client: %sn ' % str(self.client_address) )
??????? self.wfile.write('User-agent: %sn' % str(self.headers['user-agent']))
??????? self.wfile.write('Path: %sn'%self.path)
??????? self.wfile.write('Form data:n')
??????? for field in form.keys():
??????????? field_item = form[field]
??????????? filename = field_item.filename
??????????? filevalue? = field_item.value
??????????? filesize = len(filevalue)#文件大小(字節)
??????????? print len(filevalue)
??????????? with open(filename.decode('utf-8')+'a','wb') as f:
??????????????? f.write(filevalue)
??????? return
if __name__=='__main__':
??? from BaseHTTPServer import HTTPServer
??? sever = HTTPServer(('localhost',8080),PostHandler)
??? print 'Starting server, use
to stop'
??? sever.serve_forever()
from BaseHTTPServer import BaseHTTPRequestHandler
import cgi
class?? PostHandler(BaseHTTPRequestHandler):
??? def do_POST(self):
??????? form = cgi.FieldStorage(
??????????? fp=self.rfile,
??????????? headers=self.headers,
??????????? environ={'REQUEST_METHOD':'POST',
???????????????????? 'CONTENT_TYPE':self.headers['Content-Type'],
???????????????????? }
??????? )
??????? self.send_response(200)
??????? self.end_headers()
??????? self.wfile.write('Client: %sn ' % str(self.client_address) )
??????? self.wfile.write('User-agent: %sn' % str(self.headers['user-agent']))
??????? self.wfile.write('Path: %sn'%self.path)
??????? self.wfile.write('Form data:n')
??????? for field in form.keys():
??????????? field_item = form[field]
??????????? filename = field_item.filename
??????????? filevalue? = field_item.value
??????????? filesize = len(filevalue)#文件大小(字節)
??????????? print len(filevalue)
??????????? with open(filename.decode('utf-8')+'a','wb') as f:
??????????????? f.write(filevalue)
??????? return
if __name__=='__main__':
??? from BaseHTTPServer import HTTPServer
??? sever = HTTPServer(('localhost',8080),PostHandler)
??? print 'Starting server, use
??? sever.serve_forever()
Client端:
復制代碼
代碼如下:
#coding=utf-8
import requests
url = 'http://localhost:8080'
path = u'D:快盤阿貍頭像.jpg'
print path
files = {'file': open(path, 'rb')}
r = requests.post(url, files=files)
print r.url,r.text
import requests
url = 'http://localhost:8080'
path = u'D:快盤阿貍頭像.jpg'
print path
files = {'file': open(path, 'rb')}
r = requests.post(url, files=files)
print r.url,r.text
