微信公众号投票活动开发

Emmmmm 今天Leader不在家,悄悄給大家分享一个微信公众号网页开发,以及获取用户信息开发。

今天leader给了一个公众号投票的需求1、每个微信只能投一票2、不能重复投票。防止刷票。3、可以正常分享页面。我觉得这些需求对我这个牛(菜)逼(鸟)轰(一)轰(个)的程序员来说不是个什么大问题。哈哈哈哈哈 好不吹牛逼了。来先说思路。微信开发文档----https://mp./wiki?t=resource/res_main&id=mp1421140842/我不喜欢太多字。你们仔鸡看吧。

先画一个牛城图。。。

整体的精髓都在图上了。原创不易,转载请说明出处。谢谢谢谢。哪里不懂可以直接联系我

用户授权并获取code参数说明appid=APPID(公众号唯一标识)redirect_uri=REDIRECT_URI(授权后重定向的回调链接地址)response_type=code(返回类型,无需更改)scope=SCOPE(snsapi_base ,不弹出授权页面,直接跳转,只能获取用户openid),snsapi_userinfo 弹出授权页面,可通过openid拿到昵称、性别、所在地。)state=STATE(重定向后会带上state参数,开发者可以填写任意参数值)#wechat_redirect(无需更改)地址实例(虽是测试号,但我还是隐藏部分信息)红色字体需要根据实际更改。https://open./connect/oauth2/authorize?appid=xxxxxxxxxxx&redirect_uri=&response_type=code&scope=snsapi_userinfo&state=1#wechat_redirect

上代码吧。
