@HQ-random 你得给出你要代理哪个网址啊

@HQ-random 你得给出你要代理哪个网址啊

那我给出了要代理的网址，为什么还是报错呢

freemedom · 2024-04-03T09:52:28Z

@wnbh 我调试调试

@wnbh 我调试调试

好的

@wnbh 少了个斜杠。。。https:/这里github.com

@wnbh 少了个斜杠。。。https:/这里github.com

地址写的就是https://github.com，结果就是这样

你确定你没输错地址？我刚才测试了可以

要不你重新复制仓库里的代码部署看看，我部署后一直就有这个问题

freemedom · 2024-04-03T10:50:04Z

我就是用的仓库里最新的代码，猜测你代码可能有问题

呃，那就奇怪了。你可以点进去编辑代码，截屏一下你的代码

比了一下好像没区别，这就奇怪了。估计得找个人在你的环境里调试一下才知道原因。

每一个人的cloudflare环境还有差异吗？

ioliu · 2024-04-10T03:12:15Z

是不是只能代理静态页面，代理某视频网站的时候，首页可以打开，但是点击视频，会提示invalid url

freemedom · 2024-04-11T04:24:03Z

@ioliu 大概是的，复杂一些js相关的不好改

binyuj · 2024-06-08T06:47:26Z

我在之前创建的旧workers上面粘贴这份代码也遇到了同样的问题。重新创建了新的workers粘贴这份代码又没有问题。

cloudflare pages 可以反代的吗
