我们在uniapp开发中有时会需要获取用户的手机号
可以在官方文档找到对应的方法
这里注意一点，只能通过button进行点击获取
但我们这样获取到后还需要解密
比如我这里获取到的
|------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | hljs vue <template> <view><button open-type="getPhoneNumber" @getphonenumber="getPhoneNumber">点我获取手机号</button></view> </template> <script> export default { data() { return {}; }, methods: { getPhoneNumber(e) { console.log(e.detail.errMsg); console.log(e.detail.iv); console.log(e.detail.encryptedData); } } }; </script> |
你会发现获取到的是一串密文
这个我们需要用session_key
需要通过调用wx.login
|---------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 | hljs javascript wx.login({ success (res) { if (res.code) { console.log('获取code成功，code为：' + res.code) } else { console.log('登录失败！' + res.errMsg) } } }) |
获取一个code作为参数
然后再加上appid和appsecrect调用微信提供的api
去换取openid和session_key
然后再用微信官方提供的一个js去解密
我们这里是node环境
所以引入node能用的这个js即可
使用方式在上面的那个demo.js中有
打开就是这样的

解密完成后即可获取手机号~
