uni-app开发微信小程序获取bindgetphonenumber无效？

<button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber"> </button>

Component "pages/login/login" does not have a method "getPhoneNumber" to handle event "getphonenumber".

bindgetphonenumber="getPhoneNumber"

@getphonenumber="getPhoneNumber"

<button open-type="getPhoneNumber" @getphonenumber="getPhoneNumber" class="login-but">微信登录</button>

methods：{
 getPhoneNumber(e){
  console.log(e)
 },
}
