react-redux的connect与React.forwardRef结合ref失效的解决

const CompA = React.forwardRef<OutputInterface, IProps>((props, ref) => {
  // ...
})
export default connect(mapStateToProps, mapDispatchToProps)(CompA);

import {REACT_FORWARD_REF_TYPE, REACT_MEMO_TYPE} from 'shared/ReactSymbols';
export function forwardRef<Props, ElementType: React$ElementType>(
  render: (props: Props, ref: React$Ref<ElementType>) => React$node,
) {
  // 省略边界条件判断
  const elementType = {
    $$typeof: REACT_FORWARD_REF_TYPE,
    render,
  };
  if (__DEV__) {
    let ownName;
    Object.defineProperty(elementType, 'displayName', {
      enumerable: false,
      configurable: true,
      get: function() {
        return ownName;
      },
      set: function(name) {
        ownName = name;
        if (!render.name && !render.displayName) {
          render.displayName = name;
        }
      },
    });
  }
  return elementType;
}

const CompA = React.forwardRef<OutputInterface, IProps>((props, ref) => {
  // ...
})
// 直接通过render获取渲染组件
export default connect(mapStateToProps, mapDispatchToProps)(CompA.render);

const CompA = React.forwardRef<OutputInterface, IProps>((props, ref) => {
  // ...
})
// 直接通过render获取渲染组件
export default connect(mapStateToProps, mapDispatchToProps, null, {
  forwardRef: true
})(CompA);
