React Native Firebase动态链接分享至Messenger跳转异常求助

Let's break down what's happening here and how to fix it so users can share directly from your app without extra steps.

The Root Problem

When you use the system Share API to send your Firebase dynamic link to Facebook Messenger, Messenger's internal logic is overriding your link. It's generating a custom URL based on the title and message parameters you're passing, instead of preserving the original Firebase dynamic link. This doesn't happen when you paste the link directly because Messenger only gets the raw URL (and uses the social metadata embedded in the dynamic link itself).

Step-by-Step Solutions

1. Simplify Your Share Parameters

Messenger gets confused when you pass multiple conflicting text fields (title, message, url all at once). Trim down the share payload to focus on the dynamic link, and fold your title/description into the message field:

firebase.links().createShortDynamicLink(link, 'SHORT')
  .then((url) => {
    // First, confirm the URL is a valid Firebase short link (e.g. https://abc123.app.goo.gl/xyz)
    console.log("Generated Firebase Link:", url);
    
    Share.share({
      message: "Social Title - Description", // Combine your title and description here
      url: url
    }, {
      dialogTitle: 'Super Share'
    })
  });

2. Platform-Specific Tweaks

Android: Some versions of Messenger prioritize the message text over the url parameter. Include the link directly in your message to ensure it's preserved:
```
message: `Check this out: ${url}\nSocial Title - Description`
```
iOS: iOS's Share Sheet generally respects the url parameter as long as you don't pass a conflicting title field. Stick to just message and url here.

3. Verify Your Firebase Dynamic Link Metadata

Even though pasting works, double-check that your dynamic link's social metadata is correctly embedded. This ensures Messenger pulls the right title/description directly from the link, instead of relying on your share parameters:

Use Firebase's dynamic link debugging tool (in the Firebase Console) to inspect your short link.
Confirm the og:title, og:description, and og:image fields match what you set in your code with .social.setTitle(), etc.

Why Copy-Paste Works

When you paste the raw Firebase link into Messenger, the app only receives the URL. It then fetches the embedded social metadata directly from the dynamic link, so it uses the original URL for navigation. The Share API's extra text parameters trigger Messenger's custom link-generation logic, which replaces your dynamic link.
