好了，我觉得有必要对前一阶段的小程序开发过程中的一些经验写出来，总结一下，今天呢，就来总结一下小程序登录注册相关的流程和开发过程中需要注意的问题，好了，废话不多说，开始咯！
一：登录
思路：
当用户在未登录状态下点击“登录”按钮之后，执行login函数，先用wx.login获取登录凭证code， encryptedData和iv ， 然后把这三个参数发送过去，取回来 isLogin1，如果他是1，则代表该用户已经注册过，则不需要进行注册，点击登录直接就 可以微信登录，然后跳转到首页，如果为2，则代表该用户是新用户，需要跳转到注册页面进行注册，但是在这之前，需要给后台发送空的 username、phone、password、phone_code、head_photo，还有code值过去，如果返回状态是100，则跳转到注册页面注册完成后自动进入登录 状态，然后跳转首页。 个人中心页面wxml:

大家看不明白的可以问我，因为涉及到的东西比较多，所以就不一一赘述了，还有一点灰常重要，那就是一定要多和后台 交流，因为有的东西需要两个人共同完成，不要以为后台给了数据，你就可以为所欲为了，no！！！合作才能共赢。
