Facebook网页托管上传游戏资源报错：已引用CDN SDK仍不符合要求

Hey there, let’s work through this frustrating error you’re facing with Facebook’s game hosting. I’ve helped a few developers troubleshoot this exact issue post-platform updates, so here’s what to check step by step:

• First, confirm your SDK URL is complete and valid
  The truncated URL you mentioned (https://co...) is a red flag. Facebook requires you to use their full, official CDN links for supported SDKs. For example, the correct Facebook Instant Games SDK CDN link looks like:

  <script type="text/javascript" src="https://connect.facebook.net/en_US/fbinstant.6.3.js"></script>
  

  Double-check that your script tag uses the full, unbroken URL for a supported SDK (like the Gaming SDK or core JavaScript SDK). Also, move the script tag to the bottom of your <body> section—right before </body>—to ensure it loads properly after the DOM is ready.

• Don’t skip SDK initialization
  Just adding the script tag isn’t enough. Facebook’s hosting system checks for active SDK usage, not just a reference. You need to include proper initialization code. For Instant Games, that means something like:

  window.fbAsyncInit = function() {
    FBInstant.initializeAsync()
      .then(() => {
        // Your game's setup logic here
      })
      .catch(err => console.error("FB SDK init failed:", err));
  };
  

  Without this initialization, the platform can’t detect that you’re actually using the SDK, even if the script is loaded.

• Verify your zip package structure
  Make sure your main index.html file is in the root of the zip folder—not nested inside a subdirectory. Facebook’s hosting system looks for the entry point at the root level; if it’s buried, it won’t find your SDK reference. Also, check that all resource paths (images, CSS, other JS files) are relative to index.html to avoid loading failures that could break SDK detection.

• Check for recent platform rule changes
  Since you noted this error started after a "related event," it’s likely Facebook updated their hosting validation rules. Review their official game hosting docs to see if there are new requirements, like mandatory SDK versions or updated initialization steps.

• Test locally first
  Open your index.html in a browser, pull up the developer console (F12), and check for any SDK loading errors. If the SDK fails to load locally, it will definitely fail on Facebook’s hosting. Fix any console errors (like broken URLs or CORS issues) before re-packaging and uploading.
