从亚马逊服务器执行请求时获取 403

[英]Getting 403 when executing request from amazon server

原文 2022-08-03 23:53:35 0 1 c#/ amazon/ webrequest

Very same code works fine from other locations, but whenever is run from amazon server it gets 403.非常相同的代码在其他位置运行良好，但无论何时从亚马逊服务器运行，它都会得到 403。
We tried "everything":我们尝试了“一切”：

checking with postman与 postman 检查
copying cookies复制 cookies
copying / not copying the headers.复制/不复制标题。

whatever we do we get 403 when code / request is run from amazon server.无论我们做什么，当代码/请求从亚马逊服务器运行时，我们都会得到 403。 What is even more interesting: browsers work fine (you can get to the same link from any browser without any errors).更有趣的是：浏览器工作正常（您可以从任何浏览器访问相同的链接而不会出现任何错误）。 So the conclusion is like "something blocks requests that are not sent with the browser and we can't impersonate aby browser".所以结论就像“有些东西阻止了不是用浏览器发送的请求，我们不能通过浏览器来模拟”。

thanks in advance!提前致谢！

PS as far what i know it's fine from some other hosting services, only Amazon seems to be blocked. PS 据我所知，其他一些托管服务还不错，只有亚马逊似乎被屏蔽了。
Requests are not passed from any app / any language, including Postman but they're fine when any browser is used.请求不会从任何应用程序/任何语言（包括 Postman）传递，但在使用任何浏览器时都可以。 So it's like "something" detects the original source of request and if request comes from amz "it" blocks the request.所以这就像“某物”检测到请求的原始来源，如果请求来自 amz，“它”会阻止该请求。 Everything is fine when not used from amz servers)不从 amz 服务器使用时一切都很好）
