如何在 React App 中 运行 AWS 调用尝试次数超过错误？
How to Run AWS in React App Without Call Tries Exceeded Error?
我正在尝试构建一个 React phone 应用程序，它在启动后连接到 AWS。我第一次 运行 使用 Expo 的应用程序时，我收到了一个关于缺少模块“Util”的错误，所以我按照这个单独的 to resolve that issue. Afterwards, I got another issue regarding "filesys.existsSync is not a function," so I followed this other 来解决这个问题。
当我关注第二个线程时，我通过 websocket 协议连接客户端，而不是使用证书。进行这些更改后，我测试了 node.js 文件中的连接是否有效，并且连接没有任何问题。我还可以确认 React 应用程序在没有 AWS 代码的情况下在 Expo 上运行没有错误。但是，一旦我尝试将两者结合起来，我就会得到以下 error.
在 Expo 中，我收到以下错误记录：

似乎 aws-sdk 中的某些东西正在进行某种不断失败的调用，因此它一直在重试进行该调用，直到超过它可以重试调用的次数。我不确定这会是什么或为什么会发生，但我们将不胜感激！下面是我的 App.js 文件。
import React, {Component} from 'react';
import { Button, Dimensions, StatusBar, StyleSheet, Text, TextInput, Platform, View, Image } from 'react-native';
import VerticalViewPager from 'react-native-vertical-view-pager/src/component/VerticalViewPager';
import { NavigationContainer } from '@react-navigation/native';
import Test from './Test.js';
import Car from './Car.js';
import Menu from './Menu.js';
import Charging from './Charging.js';
import Aws from 'aws-sdk/dist/aws-sdk-react-native';
import awsIot from 'aws-iot-device-sdk';
import './shim.js';
const AWS_REGION = 'us-east-2';
const AWS_COGNITO_IDENTITY_POOL = 'us-east-2:XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX';
const AWS_IOT_ENDPOINT = 'XXXXXXXXXXXX.iot.us-east-2.amazonaws.com';
Aws.config.region = AWS_REGION
Aws.config.credentials = new Aws.CognitoIdentityCredentials({
IdentityPoolId: AWS_COGNITO_IDENTITY_POOL
})
export default class App extends React.Component {
constructor(props) {
super(props);
this.IotConnect();
}
IoTConnect() {
Aws.config.credentials.get(() => {
const config = {}
let client
config.host = AWS_IOT_ENDPOINT
config.protocol = 'wss'
config.clientId = `client-${Math.floor((Math.random() * 100000) + 1)}`
config.accessKeyId = 'XXXXXXXXXXXXXX';
config.secretKey = 'XXXXXXXXXXXXXXXXXXX';
config.sessionToken = Aws.config.credentials.sessionToken
client = awsIot.device(config)
client.on('connect', () => {
console.log("Successful connection");
})
client.on('error', error => {
console.log(error)
})
})
}
render() {
return (
<NavigationContainer>
<VerticalViewPager showsVerticalScrollIndicator={false}>
<Test></Test>
<Car></Car>
<Menu></Menu>
<Charging></Charging>
</VerticalViewPager>
</NavigationContainer>
);
}
}
折腾了半天，总算是找到了问题所在。无论出于何种原因，expo/React 不喜欢导入 import Aws from 'aws-sdk/dist/aws-sdk-react-native';，因此我改为将其更改为 import Aws from 'aws-sdk'。即使更改了导入，我仍然可以调用 Aws.config，因此无需对代码进行重大更改。我还将以下代码块移动到 IoTConnect 函数中：
Aws.config.credentials = new Aws.CognitoIdentityCredentials({
IdentityPoolId: AWS_COGNITO_IDENTITY_POOL
})
我不确定这是否会影响运行，但安全总比后悔好。
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，这表明它由于某种原因破坏了应用程序。我假设导入被反复调用，直到堆中没有任何 space。
我正在尝试构建一个 React phone 应用程序，它在启动后连接到 AWS。我第一次 运行 使用 Expo 的应用程序时，我收到了一个关于缺少模块“Util”的错误，所以我按照这个单独的
当我关注第二个线程时，我通过 websocket 协议连接客户端，而不是使用证书。进行这些更改后，我测试了 node.js 文件中的连接是否有效，并且连接没有任何问题。我还可以确认 React 应用程序在没有 AWS 代码的情况下在 Expo 上运行没有错误。但是，一旦我尝试将两者结合起来，我就会得到以下 error.
在 Expo 中，我收到以下错误记录：

似乎 aws-sdk 中的某些东西正在进行某种不断失败的调用，因此它一直在重试进行该调用，直到超过它可以重试调用的次数。我不确定这会是什么或为什么会发生，但我们将不胜感激！下面是我的 App.js 文件。
import React, {Component} from 'react';
import { Button, Dimensions, StatusBar, StyleSheet, Text, TextInput, Platform, View, Image } from 'react-native';
import VerticalViewPager from 'react-native-vertical-view-pager/src/component/VerticalViewPager';
import { NavigationContainer } from '@react-navigation/native';
import Test from './Test.js';
import Car from './Car.js';
import Menu from './Menu.js';
import Charging from './Charging.js';
import Aws from 'aws-sdk/dist/aws-sdk-react-native';
import awsIot from 'aws-iot-device-sdk';
import './shim.js';
const AWS_REGION = 'us-east-2';
const AWS_COGNITO_IDENTITY_POOL = 'us-east-2:XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX';
const AWS_IOT_ENDPOINT = 'XXXXXXXXXXXX.iot.us-east-2.amazonaws.com';
Aws.config.region = AWS_REGION
Aws.config.credentials = new Aws.CognitoIdentityCredentials({
IdentityPoolId: AWS_COGNITO_IDENTITY_POOL
})
export default class App extends React.Component {
constructor(props) {
super(props);
this.IotConnect();
}
IoTConnect() {
Aws.config.credentials.get(() => {
const config = {}
let client
config.host = AWS_IOT_ENDPOINT
config.protocol = 'wss'
config.clientId = `client-${Math.floor((Math.random() * 100000) + 1)}`
config.accessKeyId = 'XXXXXXXXXXXXXX';
config.secretKey = 'XXXXXXXXXXXXXXXXXXX';
config.sessionToken = Aws.config.credentials.sessionToken
client = awsIot.device(config)
client.on('connect', () => {
console.log("Successful connection");
})
client.on('error', error => {
console.log(error)
})
})
}
render() {
return (
<NavigationContainer>
<VerticalViewPager showsVerticalScrollIndicator={false}>
<Test></Test>
<Car></Car>
<Menu></Menu>
<Charging></Charging>
</VerticalViewPager>
</NavigationContainer>
);
}
}
折腾了半天，总算是找到了问题所在。无论出于何种原因，expo/React 不喜欢导入 import Aws from 'aws-sdk/dist/aws-sdk-react-native';，因此我改为将其更改为 import Aws from 'aws-sdk'。即使更改了导入，我仍然可以调用 Aws.config，因此无需对代码进行重大更改。我还将以下代码块移动到 IoTConnect 函数中：
Aws.config.credentials = new Aws.CognitoIdentityCredentials({
IdentityPoolId: AWS_COGNITO_IDENTITY_POOL
})
我不确定这是否会影响运行，但安全总比后悔好。
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，这表明它由于某种原因破坏了应用程序。我假设导入被反复调用，直到堆中没有任何 space。
