README
ReCaptcha
Add Google's Invisible ReCaptcha v2 to your project. This library automatically handles ReCaptcha's events and retrieves the validation token or notifies you to present the challenge if invisibility is not possible.
Warning ⚠️
Beware that this library only works for ReCaptcha v2 Invisible keys! Make sure to check the reCAPTCHA v2 Invisible badge option when creating your API Key.
You won't be able to use a ReCaptcha v3 key because it requires server-side validation. On v3, all challenges succeed into a token which is then validated in the server for a score. For this reason, a frontend app can't know on its own wether or not a user is valid since the challenge will always result in a valid token.
Installation
ReCaptcha is available through CocoaPods and Carthage. To install it, simply add the following line to your dependencies file:
Cocoapods
pod "ReCaptcha"
# or
pod "ReCaptcha/RxSwift"
Carthage
github "fjcaetano/ReCaptcha"
Carthage will create two different frameworks named ReCaptcha and ReCaptcha_RxSwift, the latter containing the RxSwift
extension for the ReCaptcha framework.
Usage
The reCAPTCHA keys can be specified as Info.plist keys or can be passed as parameters when instantiating ReCaptcha().
For the Info.plist configuration, add ReCaptchaKey and ReCaptchaDomain (with a protocol ex. http:// or https://) to your Info.plist and run:
let recaptcha = try? ReCaptcha()
override func viewDidLoad() {
super.viewDidLoad()
recaptcha?.configureWebView { [weak self] webview in
webview.frame = self?.view.bounds ?? CGRect.zero
}
}
func validate() {
recaptcha?.validate(on: view) { [weak self] (result: ReCaptchaResult) in
print(try? result.dematerialize())
}
}
If instead you prefer to keep the information out of the Info.plist, you can use:
let recaptcha = try? ReCaptcha(
apiKey: "YOUR_RECAPTCHA_KEY",
baseURL: URL(string: "YOUR_RECAPTCHA_DOMAIN")!
)
...
You can also install the reactive subpod and use it with RxSwift:
recaptcha.rx.validate(on: view)
.subscribe(onNext: { (token: String) in
// Do something
})
Alternte endpoint
If your app has firewall limitations that may be blocking Google's API, the JS endpoint may be changed on initialization.
It'll then point to https://www.recaptcha.net/recaptcha/api.js:
public enum Endpoint {
case default, alternate
}
let recaptcha = try? ReCaptcha(endpoint: .alternate) // Defaults to `default` when unset
