#React React-Native存取URL報錯TypeError: Network request failed［已解決］

我在寫一個簡單的登入功能，在使用API 的時候出現TypeError: Network request failed 的exception。我問過chatGPT跟搜尋過網絡，大部分的資訊都指向需要在AndroidManifest.xml 新增android: networkSecuituConfiguration，也找到相關問題串：

可是我的android/app/src/main 根本沒有xml這個資料夾，但我還是根據上面連結的方法新增xml folder 並創建react_native_config.xml，結果卻出現以下錯誤： FAILURE: Build completed with 2 failures. 1: Task failed with an exception. ----------- * What went wrong: Execution failed for task ':app:processDebugMainManifest'. > Manifest merger failed : Attribute application@networkSecurityConfig value=(@xml/react_native_config) from AndroidManifest.xml:17:7-67 is also present at AndroidManifest.xml:17:7-67 value=(@xml/network_security_config). Suggestion: add 'tools:replace="android:networkSecurityConfig"' to <application> element at AndroidManifest.xml:7:5-13:19 to override. * Try: > Run with --stacktrace option to get the stack trace. > Run with --info or --debug option to get more log output. > Run with --scan to get full insights. ============================================================================== 2: Task failed with an exception. ----------- * What went wrong: java.lang.StackOverflowError (no error message) * Try: > Run with --stacktrace option to get the stack trace. > Run with --info or --debug option to get more log output. > Run with --scan to get full insights. —————————————————————— 錯誤訊息指android: networkSecuituConfiguration 重複了，我按建議新增tools:replace 卻會出現另一個錯誤。這是我的react native project info: System: OS: macOS 13.4 CPU: (8) arm64 Apple M1 Memory: 90.45 MB / 16.00 GB Shell: 5.9 - /bin/zsh Binaries: Node: 18.14.0 - ~/.nvm/versions/node/v18.14.0/bin/node Yarn: Not Found npm: 9.3.1 - ~/.nvm/versions/node/v18.14.0/bin/npm Watchman: 2023.05.22.00 - /opt/homebrew/bin/watchman Managers: CocoaPods: 1.12.1 - /opt/homebrew/bin/pod SDKs: iOS SDK: Platforms: DriverKit 22.1, iOS 16.1, macOS 13.0, tvOS 16.1, watchOS 9.1 Android SDK: API Levels: 32, 33 Build Tools: 30.0.3, 33.0.0, 34.0.0 System Images: android-33 | Google APIs ARM 64 v8a Android NDK: Not Found IDEs: Android Studio: 2022.2 AI-222.4459.24.2221.9971841 Xcode: 14.1/14B47b - /usr/bin/xcodebuild Languages: Java: 18.0.2.1 - /usr/bin/javac npmPackages: @react-native-community/cli: Not Found react: 18.2.0 => 18.2.0 react-native: 0.71.10 => 0.71.10 react-native-macos: Not Found npmGlobalPackages: *react-native*: Not Found —————————————————————— 請問我有漏掉甚麼嗎？ 2023/06/28更新：我發現這是因為debug/AndroidManifest.xml和main/AndroidManifest.xml沒有相同的用戶權限配置，導致Manifest merger 合併失敗。我將所有用戶權限複製到 debug/AndroidManifest.xml，現在可以使用HTTP fetch了。
