复现步骤

分享函数onShareAppMessage无法使用promise对象或async/await语法

以下两种写法将导致onShareAppMessage分享函数失效，分享时图片和标题都是默认的并非onShareAppMessage所返回的对象。相同写法在原生的小程序是成功的。

import React, { Component } from 'react'
export default class Test extends Component {
  onShareAppMessage() {
    const promise = new Promise(resolve => setTimeout(() => resolve({ title: '异步标题'}), 2000))
    console.log('promise', promise)
    return {
      promise
    }
  }
  render() {
    return (
      <>test</>
    )
  }
}

import React, { Component } from 'react'
export default class Test extends Component {
  async onShareAppMessage() {
    const promise = await new Promise(resolve => setTimeout(() => resolve({ title: '异步标题'}), 2000))
    console.log('promise', promise)
    return {
      title: promise.title,
    
    }
  }
  render() {
    return (
      <>test</>
    )
  }
}

期望结果

onShareAppMessage支持异步，分享时标题图片为onShareAppMessage返回值内容

实际结果

(1)onShareAppMessage函数返回值不支持promise键值对
(2)async/await语法使得onShareAppMessage函数失效
