サーバー設定コードサンプル

以下のコードサンプルは、WebGL を使用する場合に、サーバーの設定を行うために使用してください。Nginx、Apache、および IIS サーバー用のサンプルを掲載しています。WebGL のサーバー設定に関する詳細は、圧縮ビルドとサーバーの設定 を参照してください。

WebGL ビルドのためのサーバー設定 (Nginx)

http {
# ...

server {
# Add the following config within http server configuration
# ...

# On-disk Brotli-precompressed data files should be served with compression enabled:
location ~ .+\.(data|symbols\.json)\.br$ {
    # Because this file is already pre-compressed on disk, disable the on-demand compression on it.
    # Otherwise nginx would attempt double compression.
    gzip off;
    add_header Content-Encoding br;
    default_type application/octet-stream;
}

# On-disk Brotli-precompressed JavaScript code files:
location ~ .+\.js\.br$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding br;
    default_type application/javascript;
}

# On-disk Brotli-precompressed WebAssembly files:
location ~ .+\.wasm\.br$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding br;
    # Enable streaming WebAssembly compilation by specifying the correct MIME type for
    # Wasm files.
    default_type application/wasm;
}

# On-disk gzip-precompressed data files should be served with compression enabled:
location ~ .+\.(data|symbols\.json)\.gz$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding gzip;
    default_type application/gzip;
}

# On-disk gzip-precompressed JavaScript code files:
location ~ .+\.js\.gz$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding gzip; # The correct MIME type here would be application/octet-stream, but due to Safari bug https://bugs.webkit.org/show_bug.cgi?id=247421, it's preferable to use MIME Type application/gzip instead.
    default_type application/javascript;
}

# On-disk gzip-precompressed WebAssembly files:
location ~ .+\.wasm\.gz$ {
    gzip off; # Do not attempt dynamic gzip compression on an already compressed file
    add_header Content-Encoding gzip;
    # Enable streaming WebAssembly compilation by specifying the correct MIME type for
    # Wasm files.
    default_type application/wasm;
}
}
}

WebGL ビルドのためのサーバー設定 (Apache)

Apache で WebGL ビルドを設定するには、2 つの方法 (httpd.conf の Virtual Host か .htaccess) のいずれかを使用します。Unity は Apache の httpd.conf の Virtual Host (バーチャルホスト) を設定することを推奨しています。

httpd.conf メソッドのバーチャルホストを使用して WebGL ビルドの設定を行う方法

<Directory /var/www/html/root/path/to/your/unity/content/>
<IfModule mod_mime.c>
RemoveType .gz
AddEncoding gzip .gz
# The correct MIME type for .data.gz would be application/octet-stream, but due to Safari bug https://bugs.webkit.org/show_bug.cgi?id=247421, it is preferable to use MIME Type application/gzip instead.
# AddType application/octet-stream .data.gz
AddType application/gzip .data.gz
AddType application/wasm .wasm.gz
AddType application/javascript .js.gz
AddType application/octet-stream .symbols.json.gz

RemoveType .br
AddEncoding br .br
AddType application/octet-stream .data.br
AddType application/wasm .wasm.br
AddType application/javascript .js.br
AddType application/octet-stream .symbols.json.br

</IfModule>
</Directory>

.htaccess メソッドを使用して WebGL ビルドの設定を行う方法

httpd.conf に変更を加えることができないが (例えばウェブホスティングの管理者権限がないなどの理由)、Apache が .htaccess をサポートしている場合" は、以下の方法で .htaccess の設定を行えます。

# This configuration file should be uploaded to the server as "<Application Folder>/Build/.htaccess"
# NOTE: "mod_mime" Apache module must be enabled for this configuration to work.
<IfModule mod_mime.c>

# The following lines are required for builds without decompression fallback, compressed with gzip
RemoveType .gz
AddEncoding gzip .gz
AddType application/gzip .data.gz # The correct MIME type here would be application/octet-stream, but due to Safari bug https://bugs.webkit.org/show_bug.cgi?id=247421, it's preferable to use MIME Type application/gzip instead.
AddType application/wasm .wasm.gz
AddType application/javascript .js.gz
AddType application/octet-stream .symbols.json.gz

# The following lines are required for builds without decompression fallback, compressed with Brotli
RemoveType .br
RemoveLanguage .br
AddEncoding br .br
AddType application/octet-stream .data.br
AddType application/wasm .wasm.br
AddType application/javascript .js.br
AddType application/octet-stream .symbols.json.br

# The following line improves loading performance for uncompressed builds
AddType application/wasm .wasm

# Uncomment the following line to improve loading performance for gzip-compressed builds with decompression fallback
# AddEncoding gzip .unityweb

# Uncomment the following line to improve loading performance for brotli-compressed builds with decompression fallback
# AddEncoding br .unityweb

</IfModule>

 The following server configuration can be used for compressed WebGL builds without decompression fallback.
 This configuration file should be uploaded to the server as "<Application Folder>/Build/web.config".

NOTE: To host compressed WebGL builds without decompression fallback, you need to install the "URL Rewrite" IIS module on the server.
Otherwise, IIS will throw an exception when using this configuration file.
This module is available at https://www.iis.net/downloads/microsoft/url-rewrite.
