Firebase动态链接无法获取参数

Question

我正在开发我的应用中的邀请功能，我希望用户可以推荐给其他人，推荐人在被推荐人注册后会获得奖励。我正在参照Firebase邀请教程，在第二步中，我们通过使用参数invitedby=SENDER_UID从普通链接创建了一个动态链接。

           String link = "https://samplelink.com/?invitedby=" + user.getPhone();
        Log.e(TAG, "Generated link: "+link);
        FirebaseDynamicLinks.getInstance().createDynamicLink()
                .setLink(Uri.parse(link))
                .setDynamicLinkDomain(getString(R.string.dynamic_link_domain))
                .setAndroidParameters(
                        new DynamicLink.AndroidParameters.Builder(getPackageName())
                                .build())
                .setIosParameters(
                        new DynamicLink.IosParameters.Builder("com.example.ios")
                                //.setAppStoreId("123456789")
                              //  .setMinimumVersion("1.0.1")
                                .build())
                .buildShortDynamicLink()
                .addOnSuccessListener(shortDynamicLink -> {

                    Uri mInvitationUrl = shortDynamicLink.getShortLink();
                    Log.e(TAG, "generated URL: "+mInvitationUrl.toString());
                    Intent intent = new AppInviteInvitation.IntentBuilder(getString(R.string.invite_and_earn))
                            .setMessage(getString(R.string.invitation_message))
                            .setDeepLink(mInvitationUrl)
                            //   .setCustomImage(Uri.parse(getString(R.string.invitation_custom_image)))
                           // .setCallToActionText(user.getPhone())
                            .build();
                    startActivityForResult(intent, REQUEST_INVITE);
                }).addOnFailureListener(e -> Log.e(TAG, "Error Generating Deeplink: "+e.getLocalizedMessage()));


    });

并发送生成的短动态链接。当用户在步骤4中打开应用程序时，我们获得了类似于该链接的链接。

 FirebaseDynamicLinks.getInstance()
        .getDynamicLink(getIntent())
        .addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
            @Override
            public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
                // Get deep link from result (may be null if no link is found)
                Uri deepLink = null;
                if (pendingDynamicLinkData != null) {
                    deepLink = pendingDynamicLinkData.getLink();
                }
                //
                // If the user isn't signed in and the pending Dynamic Link is
                // an invitation, sign in the user anonymously, and record the
                // referrer's UID.
                //
                FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                if (user == null
                        && deepLink != null
                        && deepLink.getBooleanQueryParameter("invitedby")) {
                    String referrerUid = deepLink.getQueryParameter("invitedby");
                    createAnonymousAccountWithReferrerInfo(referrerUid);
                }
            }
        });

链接生成的短动态链接很好，发送后，在浏览器中打开时显示原始链接https://samplelink.com/?invitedby=" + user.getPhone()，但在应用程序中，我只得到了shortdynamiclink，因此invitedby从未被找到过。有人遇到过这个问题吗？

不要将参数与链接连接起来，而是可以使用appendQueryParameter()

String link = "https://samplelink.com/";
        Log.e(TAG, "Generated link: "+link);
        FirebaseDynamicLinks.getInstance().createDynamicLink()
                .setLink(Uri.parse(link).buildUpon().appendQueryParameter("invitedby",user.getPhone()).build())
                .setDynamicLinkDomain(getString(R.string.dynamic_link_domain))
                .setAndroidParameters(
                        new DynamicLink.AndroidParameters.Builder(getPackageName())
                                .build())
                .setIosParameters(
                        new DynamicLink.IosParameters.Builder("com.example.ios")
                                //.setAppStoreId("123456789")
                              //  .setMinimumVersion("1.0.1")
                                .build())

在您的活动中，可以按以下方式检索参数：

FirebaseDynamicLinks.getInstance().getDynamicLink(getActivity().getIntent())
                    .addOnSuccessListener(getActivity(), new OnSuccessListener<PendingDynamicLinkData>() {
                        @Override
                        public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
                            Uri deepLink = null;
                            if (pendingDynamicLinkData != null) {
                                deepLink = pendingDynamicLinkData.getLink();
                            }
                            final Uri finalDeepLink = deepLink;

                            if (finalDeepLink != null && finalDeepLink.getBooleanQueryParameter("invitedby", false)) {
                                String referrerPhoneId = finalDeepLink.getQueryParameter("invitedby");

邀请API变得不那么复杂了。 - Uncle

我最终使用了邀请API。

Uri uri = Uri.parse(getString(R.string.invitation_deep_link));
        Uri deepLinkPlus = Uri.withAppendedPath(uri, user.getPhone());
        Intent intent = new AppInviteInvitation.IntentBuilder(getString(R.string.invite_and_earn))
                .setMessage(getString(R.string.invitation_message))
                .setDeepLink(deepLinkPlus)
                //.setCustomImage(Uri.parse(getString(R.string.invitation_custom_image)))
                //.setCallToActionText("invitedby")
                .build();
        startActivityForResult(intent, REQUEST_INVITE);

并且从接收deeplink的活动中

 FirebaseDynamicLinks.getInstance().getDynamicLink(getIntent())
            .addOnSuccessListener(this, data -> {
                if (data == null) {
                    Log.d(TAG, "getInvitation: no data");
                    return;
                }
                Uri deepLink = data.getLink();
                String referrerPhone = deepLink.getLastPathSegment();
                SharedPreferencesUtils.saveString(this, SharedPreferencesUtils.PREF_REFERER, referrerPhone);

            })
            .addOnFailureListener(this, e -> Log.w(TAG, "getDynamicLink:onFailure", e));
