我试图建立一个反应电话应用程序，连接到AWS一旦启动。当我第一次使用博览运行这个应用程序时，我发现了一个错误，那就是我丢失了模块"Util“，所以我遵循了这个单独的线程来解决这个问题。之后，我又遇到了一个关于"filesys.existsSync不是函数“的问题，因此我跟踪了另一个线程来解决这个问题。

当我遵循第二个线程时，我通过websocket协议连接客户机，而不是使用证书。在进行了这些更改之后，我测试了连接是否在node.js文件中工作，并且没有任何问题地连接。我还可以确认，在没有AWS代码的情况下，React应用程序在世博会上运行时没有错误。然而，只要我尝试将两者结合起来，我就会得到下面的错误。

在博览中，我得到以下错误日志记录：

经过一段时间的周旋之后，我设法解决了这个问题。出于任何原因，expo/React不喜欢导入import Aws from 'aws-sdk/dist/aws-sdk-react-native';，因此我将其改为import Aws from 'aws-sdk'。即使修改了导入，我仍然可以调用Aws.config，因此不需要对代码进行大幅度的更改。我还将以下代码块移到IoTConnect函数中：

代码语言：javascript
复制
Aws.config.credentials = new Aws.CognitoIdentityCredentials({
    IdentityPoolId: AWS_COGNITO_IDENTITY_POOL
})

我不确定这是否会影响到它的运行方式，但比抱歉安全得多。

我注意到这个问题只发生在import Aws from 'aws-sdk/dist/aws-sdk-react-native';导入中，这意味着它因为某种原因而破坏了应用程序。我假设导入一次又一次地被调用，直到堆中没有任何空间。
