SVG形式のファイルがCSSで読み込めないとき

Last updated at Posted at 2018-11-09

svg形式のファイルをcssで読み込んでも、表示されなくて困った。

Content-Typeが怪しいので、httpリクエストを送信してヘッダを確認

※-k ssl証明書のエラーを無視するよ

curl --head -k https://stg.*******

text/plainで返ってきている。
webサーバがsvg形式に対応できてないのかなと、想像。

apacheのhttpd.confを修正

TypeとEncodingにsvgを追加する。

ssh ***
sudo su - 
cp /etc/httpd/conf/httpd.conf{,.20181109}
vim /etc/httpd/conf/httpd.conf
diff /etc/httpd/conf/httpd.conf{,.20181109}

< AddEncoding x-gzip gz tgz svgz
---
> AddEncoding x-gzip gz tgz
210d209
< AddType image/svg+xml svg svgz

service httpd configtest
service httpd restart

動作確認

curl --head -k https://****

Cointent-Type が image/svg+xmlになって、正常に表示された。
