为什么我的 Expo 应用程序不发送消息？

Question

我有一个用 Expo 和 wing 创建的应用程序，它有一个联系表，可以从中发送查询。

我已经开始使用已经构建的应用程序，我只是在设置我的数据。问题是发送的查询没有到达我在配置中建立的邮件，在文件 (config.php) 中，因此消息必须以 smtp 模式到达这是我的服务器配置：

$emailConfig = array(
'address' => 'xxxxxxx',
'password' => 'xxxx',
'name' => 'jose',
'smtp_host' => 'smtp.xxxx.es',
'smtp_port' => '587',
'smtp_encrypt' => 'tls'
);

应用程序，当我点击 SEND 时，调试控制台显示如下：

Toast is not defined
* application/components/PlaceFav.js:82:10 in render
- node_modules/react-native/node_modules/promise/setimmediate/core.js:37:11 in tryCallOne
- node_modules/react-native/node_modules/promise/setimmediate/core.js:123:14 in setImmediate$argument_0
- ... 8 more stack frames from framework internals

控制台输出引用的文件如下，行:

renderItem={({item, index}) =>

      this.setState({
        ...this.state,
        places: placesArray
      });
  }

}

export default withNavigation(PlaceFav);

我在Javascript和php中对React的了解还不多，我不知道这个错误是什么意思，我已经搜索了没有成功的答案。不知道我的展示是否足够让你帮到我

Answer 1

终于发现错误了，初学者的错误我解释一下如果另一个用户和我一样。

问题是我没有编辑后端代码。我的意思是我在本地处理项目，后端在服务器上。我修改了本地文件中的代码，但没有将更新上传到服务器这就是未发送来自应用程序的消息的原因

我希望这可以帮助其他人，这让我觉得在寻求帮助和解决方案之前必须检查所有可能的错误。感谢这个精彩的网站
