求教微信公共平台第三方接口python实现，无法返回数据给客户端？咋整？

Question

def weixin(request):
	try: # 微信接口认证 使用GET方式
		if request.method == 'GET':
			token = 'air2you'
			tmpArr =[token, request.GET['timestamp'], request.GET['nonce']]
			tmpArr.sort()
			tmpArr.sort()
			tmpStr = ''.join(tmpArr)
			code = hashlib.sha1(tmpStr).hexdigest()
			if code  == request.GET['signature']:
				return render_to_response('air/weixin.html',{'echostr':request.GET['echostr']})		
			else: 
				return render_to_response('air/weixin.html',{'echostr':''})
		# 微信接口通讯 返回用户需要数据
		elif request.method == 'POST':
			xml = et.fromstring(request.raw_post_data)
			_to = xml.find('FromUserName').text
			_from = xml.find('ToUserName').text
			_content = 'welcome!'
			_type = 'text'
			return render_to_response('air/weixin.xml',{'_to':_to, '_from': _from, '_time' : int(time.time()), '_type': _type, '_content' : _content}, mimetype='application/xml')
	except Exception, e:
		return render_to_response('air/weixin.html',{'echostr':''})
#weixin.xml<xml><ToUserName><![CDATA[{{ _to }}]]></ToUserName><FromUserName><![CDATA[{{ _from }}]]></FromUserName><CreateTime>{{ _time }}</CreateTime><MsgType><![CDATA[{{ _type }}]]></MsgType><Content><![CDATA[{{ _content }}]]></Content><FuncFlag>0</FuncFlag></xml>

Answer 1

添加一个response header试试: content_type = 'application/xml'
