完成 VUI-百度语音之Rest接口python学习笔记1

我们可以开始测试pcm文件的语音识别

#example2

import os
import base64
import httplib
import urllib
import urllib2

server_url = "http://vop.baidu.com/server_api"
file_name = 'test.pcm'

file_obj = open(file_name, 'rb');
para = {}
para['format']='pcm'
para['rate']=8000
para['channel']='1'
para['token']=current_token
para['cuid']='00001'
para['len']= os.path.getsize(file_name)
para['speech']=base64.b64encode(file_obj.read())

para_json_str=json.dumps(para)

#print para_json_str

para_data = urllib.urlencode(para)

file_obj.close()
header_data = {'Content-Type':'application/json'}

vop_url_request = urllib2.Request(server_url, para_json_str, header_data)
vop_response = urllib2.urlopen(vop_url_request)
		
vop_data= json.loads(vop_response.read())

#print vop_data
if vop_data['err_msg']=='success.':

    print 'Result is: '+ result
else:
    print 'Error: '+str(vop_data['err_no'])+' '+vop_data['err_msg']
