微信公众平台开发(78) 笑话

微信公众平台上实现笑话是个很受欢迎的功能,经常有人问怎么做笑话,方倍工作室提供了接口100里面有个笑话API的。

笑话接口为:

013. 笑话

http://apix.sinaapp.com/joke/?appkey=trialuser

返回如下:

"有三个准球迷,国籍是中、日、韩,死后同时到了上帝的面前,上帝对他们说:“按照惯例你们每人可以问一个问题。”日本球迷最先问:“日本何时拿到大力神杯?”上帝说:“还要50年!”日本球迷流着眼泪离开了。韩国球迷问了同样的问题,上帝说还要100年,韩国球迷同样哭着走了。中国球迷也问上帝:“大力神何日落户中国?”上帝走上前紧紧地握住他的手,上帝哭了。"
"老师问:“铁放在外面,常和空气接触,就会生锈。那么金呢?”学生答:“会被偷。”"
"妻子比平时晚回来了两小时,丈夫大发雷霆:“干什么去了,怎么晚了两个小时!” “实在对不起。不过也没有办法,车站的自动扶梯坏了,我正站在扶梯上,只好一直等到故障完全排除。” “什么?你说你在扶梯上站了两个小时?你真是个傻瓜!你干嘛不坐着等呢?!”"

 

实现很简单,直接调用笑话接口即可
