Question

我在网站上提到了许多问题，但是使用Firebase动态链接生成短动态链接仍然没有麻烦。

我正在尝试从动态链接生成短动态链接。生成动态链接后，它可以完美地工作并可以与任何其他应用共享。但是无法从该动态链接生成短链接。

它在logcat中显示这样的错误：

com.google.android.gms.common.api.ApiException: 400: Cannot shorten a short Dynamic Link: https://onestickers.page.link/Stickers?sd=Stickers%20for%20WhatsApp%20-%20WAStickerApps&si=https%3A%2F%2Fonestickers.com%2Fimg%2Fmain-logo.png&st=One%20Stickers&amv=11&apn=stickersforwhatsapp.wastickerapps&link=https%3A%2F%2Fapi.wastickerapp.co%3Fpackid%3D201

我正在使用代码创建动态链接：

private void createShareUri(String pid) {
    Uri.Builder builder = new Uri.Builder();
    builder.scheme("https")
            .authority("api.wastickerapp.co")
            .appendQueryParameter("packid", pid);

    DynamicLink dynamicLink = FirebaseDynamicLinks.getInstance()
            .createDynamicLink()
            .setDomainUriPrefix("https://onestickers.page.link/Stickers")
            .setAndroidParameters(new DynamicLink.AndroidParameters.Builder()
                    .setMinimumVersion(11)
                    .build())
            .setSocialMetaTagParameters(
                    new DynamicLink.SocialMetaTagParameters.Builder()
                            .setTitle("One Stickers")
                            .setDescription("Stickers for WhatsApp - WAStickerApps")
                            .setImageUrl(Uri.parse("https://onestickers.com/img/main-logo.png"))
                            .build())
            .setLink(builder.build())
            .buildDynamicLink();
}

这将成功生成动态链接： https://onestickers.page.link/Stickers?sd=Stickers%20for%20WhatsApp%20-%20WAStickerApps&si=https%3A%2F%2Fonestickers.com%2Fimg%2Fmain-logo.png&st=One%20Stickers&amv=11&apn=stickersforwhatsapp.wastickerapps&link=https%3A%2F%2Fapi.wastickerapp.co%3Fpackid%3D201

如果我将这个链接通过Intent发送到任何应用程序，它也可以正常工作！

但是在那之后，我试图生成短链接：

private void createShortDynamicLink(Uri uri) {
    FirebaseDynamicLinks.getInstance()
            .createDynamicLink()
            .setLongLink(uri)
            .buildShortDynamicLink()
            .addOnCompleteListener(this, task -> {
                if (task.isSuccessful()) {
                    Uri shortLink = Objects.requireNonNull(task.getResult()).getShortLink();
                    //Uri flowchartLink = task.getResult().getPreviewLink();
                    Intent intent = new Intent();
                    intent.setAction(Intent.ACTION_SEND);
                    intent.setType("text/plain");
                    intent.putExtra(Intent.EXTRA_SUBJECT, "Stickers Link");
                    intent.putExtra(Intent.EXTRA_TEXT, shortLink.toString());
                    startActivity(intent);
                }
            }).addOnFailureListener(mContext, e -> Log.e("DynamicLink>>>", Log.getStackTraceString(e)));
}

然后显示logcat！：

E/DynamicLink>>>: com.google.android.gms.common.api.ApiException: 400: Cannot shorten a short Dynamic Link: https://onestickers.page.link/Stickers?sd=Stickers%20for%20WhatsApp%20-%20WAStickerApps&si=https%3A%2F%2Fonestickers.com%2Fimg%2Fmain-logo.png&st=One%20Stickers&amv=11&apn=stickersforwhatsapp.wastickerapps&link=https%3A%2F%2Fapi.wastickerapp.co%3Fpackid%3D201 [https://firebase.google.com/docs/dynamic-links/rest#create_a_short_link_from_parameters]

如果Android中还有其他技术，请提出建议。

在创建这样的长链接时也要创建短链接

Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
        .authority("api.wastickerapp.co")
        .appendQueryParameter("packid", pid);

FirebaseDynamicLinks.getInstance().createDynamicLink()
            .setLink(builder.build())
            .setDomainUriPrefix("https://onestickers.page.link/Stickers")
            .setAndroidParameters(
                new DynamicLink.AndroidParameters.Builder()
                    .setMinimumVersion(11)
                    .build())
            .setSocialMetaTagParameters(
                new DynamicLink.SocialMetaTagParameters.Builder()
                        .setTitle("One Stickers")
                        .setDescription("Stickers for WhatsApp - WAStickerApps")
                        .setImageUrl(Uri.parse("https://onestickers.com/img/main-logo.png"))
                        .build())
            .buildShortDynamicLink()

尝试使用原始网址 https://app.page.link/ 而不是 https://app.page.link/ChosenName

在您的情况下，它将是： setDomainUriPrefix("https://onestickers.page.link/") 而不是 setDomainUriPrefix("https://onestickers.page.link/Stickers")

Firebase动态链接无法缩短简短的动态链接
