ios - 无法从 Firebase 缩短的动态链接 URL 检索动态链接

Question

通过 WhatsApp 打开时，无法从使用 Firebase 动态链接创建的短网址中检索动态链接。

当通过 Skype 打开时，它会显示预览屏幕，但当使用 WhatsApp 单击 URL 时，它会直接打开应用程序，而不打开预览屏幕，之后我无法检索动态链接。我使用以下代码来创建和缩短动态链接:

guard let link = URL(string: "https://example.com/abc/\(id)") else { return }
        let dynamicLinksDomainURIPrefix = "https://myexample.online"
        let linkBuilder = DynamicLinkComponents(link: link, domainURIPrefix: dynamicLinksDomainURIPrefix)

        linkBuilder?.iOSParameters = DynamicLinkIOSParameters(bundleID: "bundleID")
        linkBuilder?.iOSParameters?.appStoreID = "appStoreID"
        linkBuilder?.androidParameters = DynamicLinkAndroidParameters(packageName: "packageName")
        linkBuilder?.options = DynamicLinkComponentsOptions()
        linkBuilder?.options?.pathLength = .short

        guard let longDynamicLink = linkBuilder?.url else {
            Alert.HideProgressHud(Onview: self.view)
            return
        }
        DispatchQueue.main.async {

            DynamicLinkComponents.shortenURL(longDynamicLink, options: linkBuilder?.options) { url, warnings, error in
                let url = url
                self.openactivityPickerForSharing(capturedImage: capturedImage, url: url)
            }
        }

在 AppDelegate 中，我使用以下函数接收此消息:

        if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
            // Handle the deep link. For example, show the deep-linked content or
            // apply a promotional offer to the user's account.
            // [START_EXCLUDE]
            // In this sample, we just open an alert.
            handleDynamicLink(dynamicLink)
            // [END_EXCLUDE]
            return true
        }
        return application(app, open: url,sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,annotation: "")
    }

    func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
            // Handle the deep link. For example, show the deep-linked content or
            // apply a promotional offer to the user's account.
            // [START_EXCLUDE]
            // In this sample, we just open an alert.
            handleDynamicLink(dynamicLink)
            // [END_EXCLUDE]
            return true
        }
        // [START_EXCLUDE silent]
        // Show the deep link that the app was called with.
        //showDeepLinkAlertView(withMessage: "openURL:\n\(url)")
        // [END_EXCLUDE]
        return false
    }
    // [END openurl]
// [START continueuseractivity]
    func application(_ application: UIApplication, continue userActivity: NSUserActivity,
                     restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
        let handled = DynamicLinks.dynamicLinks().handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
            // [START_EXCLUDE]
           //self.showDeepLinkAlertView(withMessage: "\(dynamiclink)")
            // [END_EXCLUDE]
        }
//handled is always returned always
        // [START_EXCLUDE silent]
        if !handled {
           //Handled the URL received in Case of Skype.
        }
        // [END_EXCLUDE]
        return handled
    }

 func handleDynamicLink(_ dynamicLink: DynamicLink) {
        let matchConfidence: String
        if dynamicLink.matchType == .weak {
            matchConfidence = "Weak"
        } else {
            matchConfidence = "Strong"
        }
        let message = "App URL: \(dynamicLink.url?.absoluteString ?? "")\n" +
        "Match Confidence: \(matchConfidence)\nMinimum App Version: \(dynamicLink.minimumAppVersion ?? "")"
    }

此后，当我点击 WhatsApp 上共享的缩短 URL 时，我收到的 URL 是 Firbase Dynamic Links 创建的缩短 URL，而不是实际的 URL

在示例中，Firebase 从 useractivity.webpageURL 读取 URL。如果您从闭包中的 dynamicLink.url 读取 url，您将看到原始的动态链接。

func application(_ application: UIApplication, continue userActivity: NSUserActivity,
                 restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    let handled = DynamicLinks.dynamicLinks().handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in

      print("This is the full length url: \(dynamiclink.url)")
    }
}
