BASH - 卷曲-L无法正常工作

Posted 2021-03-28

使用-L flash，curl应该遵循重定向但是我有301 Moved永久。

例如：curl -I -L -s era-min-eu.org |头-n 1

响应：HTTP / 1.1 301永久移动

你可以帮帮我吗？

谢谢

答案

您正在查看输出，只显示示例代码中的第一行。无头运行该命令会显示响应的其余部分：

$ curl -I -L -s era-min-eu.org

另一答案

正如@zzevann上面解释的那样，重定向确实有效。初始站点给出301错误，但低于它转发并显示Location: http://era-min.prod.lamp.cnrs.fr行中指示的更新站点的卷曲信息。

在更新的URL上运行curl：

$ curl -I -L -s era-min.prod.lamp.cnrs.fr

输出：
