关于Django开发微信

使用第三方包WeChat-python-sdk

# from wechat_sdk import WechatBasic
# from wechat_sdk.exceptions import ParseError
# from wechat_sdk.messages import EventMessage
# from wechat_sdk.context.framework.django import DatabaseContextStore

wechat_instance = WechatBasic(
    token=‘spreadassistant.chltec.com‘,
    appid=‘wxacbc8e8621b5140e‘,
    appsecret=‘11d1e1723475771e958d1252f6ad045a‘
)

    if request.method == ‘GET‘:
        # 检验合法性
        # 从 request 中提取基本信息 (signature, timestamp, nonce, xml)
        signature = request.GET.get(‘signature‘)
        timestamp = request.GET.get(‘timestamp‘)
        nonce = request.GET.get(‘nonce‘)

        if not wechat_instance.check_signature(signature=signature, timestamp=timestamp, nonce=nonce):
            return HttpResponseBadRequest(‘Verify Failed‘)

        return HttpResponse(
            request.GET.get(‘echostr‘, ‘‘), content_type="text/plain")

    # POST
    # 解析本次请求的 XML 数据
    try:
        wechat_instance.parse_data(data=request.body)
    except ParseError:
        return HttpResponseBadRequest(‘Invalid XML Data‘)

    # 获取解析好的微信请求信息
    message = wechat_instance.get_message()
    if isinstance(message, TextMessage):
        print ‘收到 文本消息‘
    elif isinstance(message, VoiceMessage):
        print ‘收到 语音消息‘
    elif isinstance(message, ImageMessage):
        print ‘收到 图片消息‘
    elif isinstance(message, VideoMessage):
        print ‘收到 视频消息‘
    elif isinstance(message, LinkMessage):
        print ‘收到 链接消息‘
    elif isinstance(message, LocationMessage):
        print ‘收到 地理位置消息‘
    elif isinstance(message, EventMessage):
        print ‘收到 事件消息‘
        #关注事件(包括普通关注事件和扫描二维码造成的关注事件)
        #如果 key 和 ticket 均不为空，则是扫描二维码造成的关注事件

        if message.type == ‘subscribe‘:
            print ‘这是 关注事件‘
        elif message.type == ‘unsubscribe‘:
            print ‘这是 取消关注事件‘
        elif message.type == ‘scan‘:
            print ‘这是 已关注用户扫描二维码！‘
        elif message.type == ‘location‘:
            print ‘这是 上报地理位置‘
        elif message.type == ‘click‘:
            print ‘这是 自定义菜单点击‘
        elif message.type == ‘view‘:
            print ‘这是 自定义菜单跳转链接‘
        elif message.type == ‘templatesendjobfinish‘:
            print ‘这是 模板消息‘

    reply_text = ‘已经响应了‘
    response = wechat_instance.response_text(content=reply_text)
    return HttpResponse(response, content_type="application/xml")

以上代码思路比较清晰所以做个记录吧，但是看到https://github.com/doraemonext/wechat-python-sdk表示该项目已经停止开发，推荐使用 https://github.com/jxtech/wechatpy/ 作为替代品。
