基本原理：

流程简述：通过请求贴文地址返回html匹配token值，然后携带token及贴文地址信息请求twitter官方接口api.x.com/graphql/Xl5… 获取贴文完整信息。
解析步骤：

(async () => {
  /**
   * 第一步：请求贴文地址获取token
   */

  // 注意：贴文地址必须携带get参数mx=2
  const twitterLink = 'https://x.com/itsme_urstruly/status/1810333882299887716?mx=2'

  const res = await fetch(twitterLink, {
    method: 'GET',
    headers: {
      // 必填header，可自行替换合法设备信息
      'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36'
    },
  }).then(response => response.text())

  // 从返回html字符串中的代码段“document.cookie="gt=1810518137110183953;” 匹配gt=token
  const token = res.match(/gt=(\d+);/)?.[1] // 1810518137110183953
})()

接口请求示例：

(async () => {
  /**
   * 第二步：携带token、贴文地址请求twitter官方接口
   * 接口地址：https://api.x.com/graphql/Xl5pC_lBk_gcO2ItU39DQw/TweetResultByRestId
   */

  /**
   * 取贴文地址/status/后缀数字为贴文id
   * 贴文id携带于get参数“variables的JSON key：tweetId” 中
   */
  const twitterId = twitterLink.match(/status\/(\d+)/)?.[1] // 1810333882299887716
  const url_dto = new URL('https://api.x.com/graphql/Xl5pC_lBk_gcO2ItU39DQw/TweetResultByRestId?variables={%22tweetId%22%3A%221810333882299887716%22%2C%22withCommunity%22%3Afalse%2C%22includePromotedContent%22%3Afalse%2C%22withVoice%22%3Afalse}&features={%22creator_subscriptions_tweet_preview_api_enabled%22%3Atrue%2C%22communities_web_enable_tweet_community_results_fetch%22%3Atrue%2C%22c9s_tweet_anatomy_moderator_badge_enabled%22%3Atrue%2C%22articles_preview_enabled%22%3Atrue%2C%22tweetypie_unmention_optimization_enabled%22%3Atrue%2C%22responsive_web_edit_tweet_api_enabled%22%3Atrue%2C%22graphql_is_translatable_rweb_tweet_is_translatable_enabled%22%3Atrue%2C%22view_counts_everywhere_api_enabled%22%3Atrue%2C%22longform_notetweets_consumption_enabled%22%3Atrue%2C%22responsive_web_twitter_article_tweet_consumption_enabled%22%3Atrue%2C%22tweet_awards_web_tipping_enabled%22%3Afalse%2C%22creator_subscriptions_quote_tweet_preview_enabled%22%3Afalse%2C%22freedom_of_speech_not_reach_fetch_enabled%22%3Atrue%2C%22standardized_nudges_misinfo%22%3Atrue%2C%22tweet_with_visibility_results_prefer_gql_limited_actions_policy_enabled%22%3Atrue%2C%22rweb_video_timestamps_enabled%22%3Atrue%2C%22longform_notetweets_rich_text_read_enabled%22%3Atrue%2C%22longform_notetweets_inline_media_enabled%22%3Atrue%2C%22rweb_tipjar_consumption_enabled%22%3Atrue%2C%22responsive_web_graphql_exclude_directive_enabled%22%3Atrue%2C%22verified_phone_label_enabled%22%3Afalse%2C%22responsive_web_graphql_skip_user_profile_image_extensions_enabled%22%3Afalse%2C%22responsive_web_graphql_timeline_navigation_enabled%22%3Atrue%2C%22responsive_web_enhance_cards_enabled%22%3Afalse}&fieldToggles={%22withArticleRichContentState%22%3Atrue%2C%22withArticlePlainText%22%3Afalse%2C%22withGrokAnalyze%22%3Afalse}')
  const variables = JSON.parse(url_dto.searchParams.get('variables') as string)
  variables.tweetId = twitterId
  url_dto.searchParams.set('variables', JSON.stringify(variables))
  const twitterAPI = url_dto.toString()

  const twitterData = await fetch(twitterAPI, {
    method: 'GET',
    headers: {
      // 必填header

})()

优点：

通过官方获取解析数据完整。
免登录无需消耗账号资源。

缺点：

每次执行需先请求贴html数据匹配token，接口等待时常较久。（优化建议：获取到的token可以缓存起来，在详情接口调用中反复使用；但需要识别token是否过期有效，如果失效还需重新获取token此缓存流程会加剧解析流程的复杂性影响稳定性）

免登录twitter官方接口数据解析（针对匿名模式浏览贴文流程逆向）
