Question

我尝试从我的

卷曲后得到以下500个回复

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.1 LTS
Release:    16.04

服务器。

什么是神秘的是几天前工作。 github.com的卷曲返回200，所以我不认为我的网络连接存在问题。在发布此问题之前，我刚刚完成了sudo apt-get update && sudo apt-get upgrade。在我的笔记本电脑上，相同的请求会返回200.如果我受到速率限制，我应该回到429.我很困惑我的服务器上发生了什么。有什么我可以调试的吗？我完全错过了什么吗？

更新：使用代理curl -vvv -L --proxy <random_http_proxy>:3128 http://soundcloud.com会回复200.我很困惑。

更新2：使用https：//不提供帮助

这个问题只是神奇地修复了它自己突然刚刚开始工作的意义上。我确实向soundcloud.com发送了支持请求，问题在第二天就消失了。我没有得到回复，他们确实采取了任何行动，例如将我的IP地址列入白名单，但我会假设这就是发生的事情。

Answer 1

尝试添加协议前缀https：//

curl -vvv -L https://soundcloud.com

我不熟悉命令行选项。

当我使用PHP curl这些选项时，它起作用了。

CURLOPT_SSL_VERIFYPEER, FALSE
CURLOPT_RETURNTRANSFER, TRUE
CURLOPT_FOLLOWLOCATION, TRUE

所需的关键选项是CURLOPT_SSL_VERIFYPEER, FALSE
仅http://而非https://

需要FOLLOWLOCATION

返回400 Bad Request而不是500

更新

通过添加看起来就像浏览器请求的请求标头，我能够获得200个HTTP响应代码，但页面是使用JavaScript创建的。所以页面上写着“JavaScript已被禁用......”

cURL to soundcloud.com返回500
