如何通过推文JSON数据获取指定推文的转发者screename列表

Great questions! Let's break this down using the X (formerly Twitter) API, since that's the official way to pull this data programmatically from tweet JSON responses.

1. 列出指定推文的所有转发者Screen Name #

To get the screen names (now officially called usernames by X) of users who retweeted a specific tweet, you'll use the X API v2 endpoint GET /2/tweets/:id/retweeted_by. Here's how it works:

• Authentication: You'll need a valid Bearer Token (for app-only access) or OAuth 1.0a credentials (for user-specific access), with the read:users and read:tweets permissions enabled.
• Endpoint Usage: Replace :id with the target tweet's unique ID. The endpoint returns a JSON response where the data array contains objects for each retweeting user. Each object includes the username field—that's the screen name you're looking for.

Example JSON response snippet:

{
  "data": [
    {
      "id": "123456789",
      "name": "Jane Doe",
      "username": "janedoe123" // This is the screen name
    },
    {
      "id": "987654321",
      "name": "John Smith",
      "username": "johnsmith_456"
    }
  ],
  "meta": {
    "result_count": 2,
    "next_token": "abc123" // Use this for pagination if there are more retweeters
  }
}

• Pagination: If the tweet has more than 100 retweeters (the default max_results limit), use the next_token from the meta object in subsequent requests to fetch the next batch of users.

2. 推文发布后获取转发者的名称 #

Once your tweet is live, you have two reliable ways to capture retweeters' screen names:

Option 1: Poll the endpoint periodically #

If real-time updates aren't a priority, simply call the same GET /2/tweets/:id/retweeted_by endpoint at regular intervals (e.g., every 5 minutes). Compare the returned usernames with your existing list to identify new retweeters.

Option 2: Use Webhooks for real-time alerts #

For instant notifications when someone retweets your tweet, set up a webhook via the X Account Activity API. Configure it to listen for retweet_events linked to your tweet. When a retweet occurs, the webhook will receive a payload containing the retweeting user's details, including their screen name.

Example webhook payload snippet (v1.1 format, which includes the legacy screen_name field):

{
  "tweet_create_events": [
    {
      "retweeted_status": {
        "id": "YOUR_TWEET_ID"
      },
      "user": {
        "id": "RETWEETER_ID",
        "name": "Retweeter Name",
        "screen_name": "retweeter_screenname" // Matches the screen name you see on X
      }
    }
  ]
}

In API v2, the field is renamed to username, but it represents the same screen name value you're targeting.
