Apache2 Ubuntu 16.04 CORSが機能しない

Webサイトにアクセスすると、コンソールタブでエラーが表示されます（Firefoxを使用）。エラーは次のとおりです。

Cross-Origin Request Blocked：Same Origin Policyは、あるWebサイトのリモートリソースの読み取りを許可しません。 （理由：CORSヘッダー「Access-Control-Allow-Origin」がありません）。

これは、CORSを正しくセットアップしなかったことを意味すると思います。 Ubuntu 16.04でApache2を使用しています

ここに私の設定ファイルがあります：

Apache2.conf：

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.Apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/Apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/Apache2/ directory:
#
#   /etc/Apache2/
#   |-- Apache2.conf
#   |   `--  ports.conf
#   |-- mods-enabled
#   |   |-- *.load
#   |   `-- *.conf
#   |-- conf-enabled
#   |   `-- *.conf
#   `-- sites-enabled
#       `-- *.conf
#
#
# * Apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual Host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called Apache2. Due to the use of environment variables, in
#   the default configuration, Apache2 needs to be started/stopped with
#   /etc/init.d/Apache2 or Apache2ctl. Calling /usr/bin/Apache2 directly will not
#   work with the default configuration.


# Global configuration
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.Apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.

# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/Apache2/envvars
#
PidFile ${Apache_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 60

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5


# These need to be set in /etc/Apache2/envvars
User ${Apache_RUN_USER}

#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.Apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual Host will be
# logged here.  If you *do* define an error logfile for a <VirtualHost>
# container, that Host's errors will be logged there and not here.
#
ErrorLog ${Apache_LOG_DIR}/error.log

#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
#
LogLevel warn

# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual Host.

Mod_headersモジュールを無効にすることができます。有効にして、Apacheをリロードしてください。

Sudo a2enmod headers
Sudo service Apache2 reload

それでもヘッダーが表示されない場合は、.htaccessファイルにこれを追加してみてください：

Header set Access-Control-Allow-Origin "*"

.htaccessファイルのCORS宣言は1箇所でのみ必要であり、vhostファイルにアクセスできるので、そこからの方がよいので、CORS宣言を取り除きます。

指定したvhostファイルを確認すると、問題が何であるかがわかります。自己閉じたディレクトリ構成<Directory />を作成しましたが、機能しません。以下のvhostファイルを書き直しました...

<VirtualHost *>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/website
    <Directory /var/www/>
        Header set Access-Control-Allow-Origin "*"
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
        # This directive allows us to have Apache2's default start page
                # in /Apache2-default/, but still have / go to the right place
                #RedirectMatch ^/$ /Apache2-default/
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">

        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog /var/log/Apache2/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks

        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

CORSヘッダーが<Directory /var/www>ブロックに移動されていることがわかります。

構成ファイルには多くの「競合」があるため、おそらく期待どおりに機能していないため、CORSヘッダーが正しく設定されていない理由も説明できます。

  • メインサーバーの設定に、<Directory>という形式の同じCORSディレクティブを持ついくつかのHeader always set Access-Control...セクションがあります（always条件に注意してください）。
  • .htaccessで同じ/類似のディレクティブを繰り返しています。 （.htaccessはサーバー設定をオーバーライドする可能性があります。ただし、無効になっています-以下を参照してください。）
  • single<VirtualHost>を持つHeader set Access-Control-Allow-Origin "*"（vHost）コンテナーがあります（欠落しているalways条件に注意してください-ヘッダーが適用）<Directory />セクションのディレクティブ。
    • VHostは、オーバーライドメインサーバー構成であるため、メインサーバー構成のCORSディレクティブはバイパスされる可能性があります。
    • VHostの<Directory>セクションはすべてAllowOverride Noneを設定します-これは.htaccessを無効にします。したがって、.htaccessのCORSディレクティブはいずれも処理されていません（そうしないと、vHostの<Directory>セクションがオーバーライドされます。
    • <Directory />セクションはサーバー全体を対象としますが、disableアクセスを除き、絶対に実行しないでください。 （サーバー全体へのアクセスを無効にし、specific<Directory>コンテナでaccess/setディレクティブを有効にします。）

メインサーバーの設定と<Directory /var/www/website>のディレクティブは<VirtualHost>の.htaccessコンテナ（DocumentRootを対象とする）への適切なディレクティブを移動する必要がありますオーバーライドされています。
