使用Python脚本获取Facebook Page直播评论遇权限及平台配置问题

Got it, let's tackle this problem step by step. Facebook's platform configuration doesn't have a specific "Python Script" entry, but there are officially supported workarounds to get your app through review and access the full comment data you need.

1. Use the "Website" Platform as a Stand-In #

Facebook allows backend/script-based apps to use the Website platform as a placeholder. Here's how to set it up:

• Go to your Facebook App's Settings > Platforms
• Click Add Platform and select Website
• Enter a valid URL (it can be a personal website you own, a GitHub Pages site, or even http://localhost:8000 for development purposes—Facebook just needs a valid entry to enable review eligibility)
• Save the changes, and you'll now see the Website platform listed, making your app eligible for permission review.

When you submit your permission request, be explicit in the description that this is a backend Python script using the Website platform as a required placeholder for review.

2. Update Your Permission Requests to Match Current Facebook API Requirements #

Note that Facebook has deprecated some older permissions (like manage_pages) in favor of more granular ones. For your use case, you should request:

• pages_read_engagement: Lets your app access comments, posts, and other engagement data from your Facebook Page
• pages_manage_posts: Required for creating and managing live streams (including pushing your screen capture to the Page)
• pages_show_list: To list the Pages your app has access to (needed for authentication flow)

In your permission review request, write a detailed, specific use case—avoid vague language. For example:

"My Python script captures screen content and pushes it as a live stream to my Facebook Page. It also needs to fetch all live stream comments in real time to process them (e.g., trigger automated responses based on keywords, track viewer sentiment, and display comment highlights during the stream). This requires access to page engagement data and live stream management capabilities."

3. Test Full Comment Access During Development #

While waiting for review, you can test with test users to verify your script works with non-admin comments:

• Go to your Facebook App's Roles > Test Users
• Create test users, then add them as followers to your Facebook Page
• Have these test users post comments on your test live streams—your app (in development mode) will be able to fetch their full comment data (including from fields with name and ID)

4. Alternative: Use Webhooks for Real-Time Comment Updates #

Instead of polling the Graph API for comments, consider setting up a Webhook for your Page. This will send comment data directly to your Python script whenever a new comment is posted, which is more efficient than continuous polling. To set this up:

• In your App's Webhooks settings, subscribe to the feed field for your Page
• Configure a public endpoint in your Python script (you can use tools like ngrok to expose your local script to the internet for testing)
• This still requires the same permissions as above, but it's a better practice for real-time data retrieval.
