Flutter IOS 通用链接打开应用程序，但没有导航到正确的页面

Question

我已经在我的 flutter 项目上为 IOS 设置了通用链接。

正如标题所暗示的那样，当我单击与我的网站相关的链接时，我的应用程序确实会打开，但它不会导航到正确的页面。 它只是打开应用程序。 我没有使用uni_links package，而是使用了指南的组合（包括官方文档）：

https://nishbhasin.medium.com/apple-universal-link-setup-in-ios-131a508b45d1

https://www.kodeco.com/6080-universal-links-make-the-connection

我已将我的 apple-app-site-association 文件设置为如下所示：

{
    "applinks": {
        "details": [
            {
                "appIDs": [
                    "XXXXXXX.com.my.appBundle"
                ],
                "componenents": [
                    {
                        "/": "/*"
                    }
                ]
            }
        ]
    }
}

我已将其添加到我的 info.plist 文件中：

<key>FlutterDeepLinkingEnabled</key>
<true/>

我的 AppDelegate.swift 文件如下所示：

import UIKit
import Flutter
import Firebase

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(_ application: UIApplication, continue userActivity: NSUserActivity, 
    restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    // This will allow us to check if we are coming from a universal link
    // and get the url with its components
    // The activity type (NSUserActivityTypeBrowsingWeb) is used
    // when continuing from a web browsing session to either
    // a web browser or a native app. Only activities of this
    // type can be continued from a web browser to a native app.
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
      let url = userActivity.webpageURL,
      let components = URLComponents(url: url, resolvingAgainstBaseURL: true) else {
        return false
    }
    // Now that we have the url and its components,
    // we can use this information to present
    // appropriate content in the app
    return true
  }

  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

我的 Runner-entitlements 也已正确设置，例如：

<key>com.apple.developer.associated-domains</key>
<array>
    <string>applinks:www.example.com</string>
    <string>applinks:*.example.com</string>
</array>

问题是，如果我单击www.example.com/mypath的超链接，它不会到达 /mypath 处理的页面/路由，而只是打开应用程序。

我的路由是使用go_router完成的：^5.2.4

请问有人知道为什么会这样吗？ 我被这个阻止了。 我见过类似的问题，但没有一个答案对我有用。 任何帮助表示赞赏。

好的，所以想通了。 Apple 官方文档要求在 AppDelegate.swift 文件中添加此 function 的变体：

func application(_ application: UIApplication, continue userActivity: NSUserActivity, 
    restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    // This will allow us to check if we are coming from a universal link
    // and get the url with its components
    // The activity type (NSUserActivityTypeBrowsingWeb) is used
    // when continuing from a web browsing session to either
    // a web browser or a native app. Only activities of this
    // type can be continued from a web browser to a native app.
    guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
      let url = userActivity.webpageURL,
      let components = URLComponents(url: url, resolvingAgainstBaseURL: true) else {
        return false
    }
    // Now that we have the url and its components,
    // we can use this information to present
    // appropriate content in the app
    return true
  }

似乎它与处理通用链接的 flutter 框架冲突。 取出 function 并将其放入我的 info.plist 中（其他一切保持不变）：

<key>FlutterDeepLinkingEnabled</key>
<true/>

Flutter 文档还没有出来（截至发布此答案时），所以如果人们有兴趣，我可以写一篇关于必要步骤的小文章。

当你处理动态链接时，你会在下面的 function 的 userActivity 参数中获得通用链接和其他数据。

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
    if let incomingURL = userActivity.webpageURL {
        debugPrint("incoming url is", incomingURL)
        let link = DynamicLinks.dynamicLinks().shouldHandleDynamicLink(fromCustomSchemeURL: incomingURL)
        print(link)
        let linkHandle = DynamicLinks.dynamicLinks().handleUniversalLink(incomingURL) { link, error in
            guard error == nil else {
                print("Error found.")
                return
            }
            if let dynamicLink = link {
                self.handleDynamicLinks(dynamicLink)
            }
        }
        if linkHandle {
            return true
        } else {
            return false
        }
    }
    return false
}

解析来自另一个 function 的数据，或者您也可以在上面的代码中解析。 就我而言，我解析了以下 function 中的代码。

func handleDynamicLinks(_ dynamicLink: DynamicLink) {
    guard let link = dynamicLink.url else {
        return
    }
    
    if let landingVC = self.window?.rootViewController as? LandingViewController {
       // Do you your handling here with any controller you want to send or anything.
    }
          // example you are getting ID, you can parse it here

    if let idString = link.valueOf("id"), let id = Int.init(idString) {
        print(id)
    }
}

当您从链接中获取详细信息时，您可以简单地获取导航 controller 或 VisibleController，然后可以推送到所需的流程。
