开发服务器返回错误代码 403 react native [英] dev server returned error code 403 react native

问题描述

---编辑---

问题可能是 McAfee 正在使用 8081 端口.所以我更新了 server.js 以在 8088 上运行开发端口，现在当我浏览 http://localhost:8088/index.android.bundle?platform=android 我可以看到 JS 加载.

但是我如何让 android 使用这个地址而不是默认的 **10.0.2.2:8081?** 我找到了一个包含 10.0.2.2 路径的文件 AndroidInfoHelpers.java 但不确定是否这就是作为 JAVA 文件的方式，我可能需要重新编译整个程序.应该有一种更简单的方法可以让 Android 应用程序为开发服务器使用不同的端口.

此外，当我执行 react-native run-android 时，获得输出的第一行显示JS 服务器无法识别.. 继续构建"，这可能是在喊同样的事情.>

解决方案

A) 为开发服务器设置新端口
用户命令react-native start --port=8088
或
yourproject ode_modules eact-nativelocal-cliserverserver.js设置可用端口说 8080
现在使用 react-native start 在 8080 上启动服务器

B) 现在要在模拟器和开发服务器之间建立通信，请使用以下命令
adb -s 模拟器 -5554 反向 tcp:8088 tcp:8088
i) 5554 => 模拟器端口(adb devices 命令会告诉您模拟器端口，但如果此命令不起作用，则在 中设置路径 C:/../android-sdk/platform-tools>Path 环境变量 )
ii) 8088 =>服务器端口

C) 运行命令 react-native run-android

D) 按照以下步骤在模拟器中更新 Dev 服务器路径

i) Windows 的 Ctrl + M 打开模拟器的开发菜单.
ii) 单击开发设置
III) 在 Debugging 下选择 Debug server host &设备端口
IV) 输入您的应用程序的 url 和端口为 10.0.2.2:8088

Followed the steps here to try react-native android on a windows box.

1. On a separate prompt I executed react-native start which is running fine
2. Started the AVD from AVD Manager
3. Executed react-native run-android

BUILD SUCCESSFUL Total time: 27.632 secs Starting the app on emulator-5554 (D:softwareAndroidandroid-sdk/platform-tool s/adb -s emulator-5554 shell am start -n com.awesomeproject/.MainActivity)... Starting: Intent { cmp=com.awesomeproject/.MainActivity }

4. Executed react-native run-android on a separate console from within same folder

But I see an error which I'm having hard time to resolve. Please suggest resolution.

---EDIT---

Possibly the issue is that 8081 port is in use by McAfee. So I updated the server.js to run dev port on 8088 and now when I browse http://localhost:8088/index.android.bundle?platform=android I can see JS loading.

But how do I make android use this address instead of default **10.0.2.2:8081?** I found a file AndroidInfoHelpers.java which contains that 10.0.2.2 path but not sure if that's the way as being a JAVA file I possibly need to recompile whole program. There should be a simpler way to point android app to use a different port for dev server.

Also, when I execute react-native run-android the first line that gets output says "JS Server not recognized.. Continuing with the build" which likely is shouting the same thing.

解决方案

A) Set the new port for dev server
User command react-native start --port=8088
or
yourproject ode_modules eact-nativelocal-cliserverserver.js to set the the available port say 8080
now use react-native start to start server on 8080

B) Now to establish communication between emulator and dev server, use below command
adb -s emulator -5554 reverse tcp:8088 tcp:8088
i) 5554 =>emulator port (adb devices command will tell you emulator port but if this command is not working then set the path C:/../android-sdk/platform-tools in Path environemnt variable )
ii) 8088 =>server port

C) run the command react-native run-android

D) Follow below steps updating Dev server path in emulator

i) Ctrl + M for windows to open your dev menu for the emulator.
ii) Click Dev Settings
III) Under Debugging select Debug server host & port for device
IV) Enter the url and port for your application as 10.0.2.2:8088
