Python模拟HTTP Post上传文件

使用urllib2模块构造http post数据结构,提交有文件的表单(multipart/form-data),本示例提交的post表单带有两个参数及一张图片,代码如下:

#buld post body data
        boundary = '----------%s' % hex(int(time.time() * 1000))
        data = []
        data.append('--%s' % boundary)
        
        data.append('Content-Disposition: form-data; name="%s"\r\n' % 'username')
        data.append('jack')
        data.append('--%s' % boundary)
        
        data.append('Content-Disposition: form-data; name="%s"\r\n' % 'mobile')
        data.append('13800138000')
        data.append('--%s' % boundary)
        
        fr=open(r'/var/qr/b.png','rb')
        data.append('Content-Disposition: form-data; name="%s"; filename="b.png"' % 'profile')
        data.append('Content-Type: %s\r\n' % 'image/png')
        data.append(fr.read())
        fr.close()
        data.append('--%s--\r\n' % boundary)
    
        http_url='http://remotserver.com/page.php'
        http_body='\r\n'.join(data)
        try:
            #buld http request
            req=urllib2.Request(http_url, data=http_body)
            #header
            req.add_header('Content-Type', 'multipart/form-data; boundary=%s' % boundary)
            req.add_header('User-Agent','Mozilla/5.0')
            req.add_header('Referer','http://remotserver.com/')
            #post data to server
            resp = urllib2.urlopen(req, timeout=5)
            #get response
            qrcont=resp.read()
            print qrcont
            
            
        except Exception,e:
            print 'http error'
