如何解决expo-cli请求实体过大（request entity too large）问题？

问题描述 #

每次执行yarn start启动Expo项目，安卓设备尝试上传并启动应用时，抛出以下错误：

Android Bundling complete 288ms
AsyncStorage has been extracted from react-native core and will be removed in a future release. It can now be installed and imported from '@react-native-async-storage/async-storage' instead of 'react-native'. See https://github.com/react-native-async-storage/async-storage

已尝试升级/降级expo-cli版本，无效；问题自迁移到Expo EAS构建系统后出现。

解决方法 #

• 调整开发服务器请求体大小限制：在项目根目录的expo.config.js（无则新建）中添加devServer配置，增大请求体上限：

  module.exports = {
    // 其他项目配置
    devServer: {
      bodyParser: {
        json: { limit: '10mb' }, // 根据实际包体积调整，如20mb
      },
    },
  };
  

  修改后重启yarn start测试。

• 优化构建包体积：

  • 清理项目中未使用的依赖、冗余图片/字体资源
  • 在eas.json中开启安卓构建的压缩与混淆：

    {
      "build": {
        "production": {
          "android": {
            "minifyEnabled": true,
            "proguardEnabled": true
          }
        }
      }
    }
    

  • 将图片转为WebP格式，压缩资源体积

• 切换调试模式：调试阶段暂时使用Expo Go本地构建替代EAS自定义包，执行expo prebuild --clean重置本地配置后，重新用yarn start启动选择Expo Go模式。

• 优化网络连接：确保设备与开发电脑在同一局域网，尝试使用USB调试模式下的网络共享，提升传输稳定性。
