快手视频获取求助
[原教程](https://learn.scriptcat.org/docs/practice/%E5%AE%9E%E6%88%98Fetch%E5%8A%AB%E6%8C%81%E5%BF%AB%E6%89%8B%E6%89%B9%E9%87%8F%E8%AF%BB%E5%8F%96/)***

好像快手更新了页面？这一步获取photoid中我没找到教程中的oparetionName：**visionVideoDetail**，好像更新为：oparetionName：**commentListQuery**（含有photoid）
!(data/attachment/forum/202310/11/130005deojnoqjhkwhzend.png)
然后个人进行修改原教程中的数据（data）：
```javascript~~~~
function getKusiShowVideo(id) {
return new Promise((resolve, reject) => {
//这里需要注意的是如果我们把获取的数据直接放到xhr内\n会出现换行的情况
//所以我们需要对这类字符进行转义，把\n改成\\n,这样提交的时候会把\\n转义成\n。
GM_xmlhttpRequest({
url: "https://www.kuaishou.com/graphql",
method: "POST",
data: '{"operationName":"commentListQuery","variables":{"photoId":"'+
id+
'","pcursor":""},"query":"query commentListQuery($photoId: String, $pcursor: String) {\\\nvisionCommentList(photoId: $photoId, pcursor: $pcursor) {\\\n commentCount\\\n pcursor\\\n rootComments {\\\n commentId\\\n authorId\\\n authorName\\\n content\\\n headurl\\\n timestamp\\\n likedCount\\\\n realLikedCount\\\\n liked\\\n status\\\n authorLiked\\\n subCommentCount\\\n subCommentsPcursor\\\n subComments {\\\n commentId\\\n authorId\\\n authorName\\\n content\\\n headurl\\\n timestamp\\\n likedCount\\\n realLikedCount\\\n liked\\\n status\\\n authorLiked\\\n replyToUserName\\\n replyTo\\\n __typename\\\n }\\\n __typename\\\n }\\\n __typename\\\n}\\\n}\\\n"}',
headers: {
"Content-type": "application/json",
},
onload: function (xhr) {
console.log(xhr.responseText)
let obj = unsafeWindow.JSON.parse(xhr.responseText);
let res = obj.data.visionProfilePhotoList.feeds;
if (res === null) {
resolve({status:"error"})
}
res.forEach((item) =>{
console.log(item.photo.photoUrl)
downloadurl.push(item.photo.photoUrl);
})
// downloadurl.push(res.photoUrl);
resolve({
status:'success',
// data:res.photoUrl
});
},
});
});
}
```
但是爆`JSON.parse: unexpected character at line 1 column 1 of the JSON data`

新版本已经不需要发送数据来获取源视频文件地址了 梦泽宇 发表于 2023-10-11 16:31
噢噢，问下道哥，你这个是具体哪个请求，我怎么没找到
现在点击新视频好像没有视频地址的获取的接口了
直接根据列表获取视频地址单独显示 李恒道 发表于 2023-10-11 15:32
新版本已经不需要发送数据 ...
