微擎小程序获取不到头像和昵称解决方案

这是一个使用微擎小程序的代码示例，其中包含了获取用户头像和昵称的功能。以下是解决方案：

1. 首先，在标签上添加open-type="chooseAvatar"属性，并绑定bindchooseavatar事件：

   

2. 在Page对象中定义onChooseAvatar函数来处理选择头像的事件：

   onChooseAvatar: function(event) {
     var that = this;
     wx.chooseImage({
       count: 1,
       success:function(res) {
         that.setData({
           avatarUrl: res.tempFilePaths[0]
         });
       }
     });
   }
   

3. 在标签中加入name="nickname"属性，设置输入框的类型为昵称：

   
     昵  称：
     
   
   

4. 在提交表单时，通过form标签的bindsubmit属性绑定getUserName事件处理函数。在事件处理函数中，可以使用event.detail.value获取用户输入的昵称和手机号：

   
     ...
   
   

   getUserName: function (event) {
     var nickname = event.detail.value.nickname;
     var mobile = event.detail.value.mobile;
     // 进行相应的逻辑处理
   }
