Summary: An HTTP request may be redirected to another URL, sometimes we need to know the URL where the response comes from. If the server is in control, we can add an HTTP header X-Request-URL for the redirect URL. However there will be cases that 3rd party services are used. This PR retrieves the response URL from native networking module and passes to it XMLHttpRequest. The fetch API built on XMLHttpRequest also benefits from this feature.

UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeproj
in Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init
which have a dependency on a specific version of React Native JS and native code, declared in a package.json
file (and build.gradle
for Android apps).
