api - tiktok api从帖子中获取视频网址，视频未显示

问题描述

我正在使用这个 tiktok API https://www.tiktok.com/node/share/video/userId/videoId，示例用法是https://www.tiktok.com/node/share/video/@beary730/6976969595781434626

它正在返回下面的 json，但那里的所有 url 都没有显示实际播放的视频 url。它只显示一个灰色的播放器，但没有内容。

那篇文章的视频网址是这个

但是下面json的返回（videoUrl）是这样的

这曾经有效，但不再有效。如何抓取实际的视频网址，以便将其嵌入到我们 html 页面的视频播放器中。我应该使用什么api？

解决方案

请求视频网址时，您需要：

  • 转发从初始 http 调用中设置的 cookie（特别是tt_webid_v2转发所有 cookie 都可以）
  • 将RefererHTTP 标头设置为 tiktok 视频 url 的值。此值存在于seoProps.metaParams.canonicalHref字段下的 json 结果中。

请注意，初始 API 调用需要设置用户代理，而视频 api 调用中不需要，但我会指定它以防万一

以下2个示例将视频保存在文件下tiktok.mp4

使用、和的示例（将 cookie 存储在 cookies.txt 中）：

#!/bin/bash

url="https://www.tiktok.com/node/share/video/@beary730/6976969595781434626"
userAgent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36"

read videoUrl referer < <(echo $(curl -c cookies.txt -s "$url" -H "User-Agent: $userAgent" | 
     jq -r '.itemInfo.itemStruct.video.downloadAddr, .seoProps.metaParams.canonicalHref'))

echo "$videoUrl"
echo "$referer"

curl -s "$videoUrl" -H "Referer: $referer" -H "User-Agent: $userAgent" -b cookies.txt -o tiktok.mp4

中带有的示例：

import requests

url = "https://www.tiktok.com/node/share/video/@beary730/6976969595781434626"
userAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36"

s = requests.Session()
r = s.get(url, headers= {
    "User-Agent": userAgent
})
data = r.json()

videoUrl = data["itemInfo"]["itemStruct"]["video"]["downloadAddr"]
referer = data["seoProps"]["metaParams"]["canonicalHref"]

print(videoUrl)
print(referer)

r = s.get(videoUrl, headers= {
    "Referer": referer,
    "User-Agent": userAgent
})
with open('tiktok.mp4', 'wb') as f:
    f.write(r.content)

您将无法在您的网站上按原样嵌入视频 url，因为它需要 cookie 和引用，除非您知道如何伪造tt_webid_v2cookie，但这并不容易，因为 cookie 值似乎取决于expires和signatureurl 参数视频网址。

请注意，它也适用于playAddr字段，它也以相同的方式获取视频馈送数据downloadAddr
