取list不行

可以按照错误提示自己搜索下，如果代码有问题，欢迎提交你的解决方案

不知道对这个空 list 从何入手，请教下是哪方面可能有问题？

[renyijiu]

最简单的你直接重试运行，出错的话你可以看输出日志的最后一行提示搜索一下，应该请求网页数据出现了问题

Found solution for pyppeteer.errors.NetworkError: Protocol error Target.createTarget: Target closed.

pip install websockets==6

@renyijiu assign in requirements.txt would be good .

So, the left problem is endless empty list ... I have no idea for now .

[renyijiu]

@eromoeIf you test and find that the code is working properly, welcome to submit your code. A new PR is great

[eromoe]

Webpage is empty in chrome mobile mode , even empty in mobile browser . So there may be a special UA or something called signature you mention in other threads .
That is really hard , unless somebody inside tiktok can leak detail to us .

[renyijiu]

@eromoe Sorry, i have not tried. you may use the project to replace the signature and try download the video, if it works perfectly， welcome to sumbit your code to optimize this project
