实现这一目标的最佳方法是什么？

const func = (newPermissions) => {
  this.setState({
    permissions: { ...newPermissions }
  },
  () => {
    if (this.state.permissions.read) {
      // If we get here then func should return the result of an api call
      // Currently the return just returns from callback of setState and func returns nothing
      return api.getInfo().then((response) => {
        return response;
      });
    }
  });
}

我尝试直接从回调返回，但它只是从setState的回调返回，而函数没有返回任何内容。

更新：潜在解决方案

这是一个潜在的解决方案吗？

const func = (newPermissions) => {
  return new Promise(resolve => {
    this.setState({
      permissions: { ...newPermissions }
    },
    () => {
      if (this.state.permissions.read) {
        resolve(api.getInfo().then((response) => {
          return response;
        }));
      }
    });
  });
}
