Flask的代码：
@app.route(‘/sipevents’, methods=[‘GET’, ‘POST’]) def sipevents(): sendArticelResp = wechat.send_article_message(sourceUser.openid, showEventArticleDict) gLog.debug("sendArticelResp=%s", sendArticelResp) return |
运行出错：

看起来很明显：
Flask中没有返回response
－》
但是此处：
故意没有返回微信公众号的内容
－》因为前面已经返回过了对应的article文章内容了
对应的公众号中可以显示了：

该公众号暂时无法提供服务，请稍后再试
就是由于上述错误，而无法正常返回，微信才显示错误的。

［总结］
Flask中，正常的话，确保返回有response回复，就可以避免：
ValueError: View function did not return a response
的错误了，而此处，确保有调用make_response即可。
比如：
return make_response("") |
