因此我尝试看看是否可以通过在 Apache 中配置来设置响应标头。
我正在使用 Debian 测试，以防万一。
我的 Web 服务器正常运行，并且我已经将它用于我正在开发的多个网站。所以现在我想要做的就是设置一个标头来查看它是否正常工作。
这是我在 apache.conf 中所做的更改
<Directory /home/web>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
Header set myHeader "Hello Header World"
</Directory>
这是我在 /etc/apache2/sites-available/000-default.conf 中的主机配置文件，如下所示：
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /home/web
AliasMatch ^/vmapi/(.*)$ /home/web/vmapi/api_receiver.php
AliasMatch ^/inherentvalue/api/(.*)$ /home/web/inherentvalue/api/api.php
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
Header set location "juancito"
Header set Location "pedrito"
Header set MyHeader "Hello Joe. It took %D microseconds for Apache to serve this request."
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
这个别名是用于我正在进行的另一个项目的。
apache2ctl -M 的输出也如下所示：

因此我尝试以下命令：
curl -i -s -k -v -X GET "http://localhost/vmportal/css"
结果是这样的：
HTTP/1.1 301 Moved Permanently

我难道不应该看到我在响应中设置的任何标题吗？
有人能告诉我我可能做错了什么吗？或者问题可能是什么？甚至如何调试？（如果您想知道的话，错误日志或访问日志中没有任何内容）。
