圖形驗(yàn)證碼加載不出來
最近利用wordpress建站的時(shí)候,用到了wechat-social-login
插件實(shí)現(xiàn)微信、QQ、釘釘、Github
登陸功能時(shí),開啟圖形驗(yàn)證碼功能后,看到圖形二維碼一直加載不出來,F12
看到狀態(tài)碼為200,但沒有返回值,報(bào)錯(cuò)This request has no response data available
打開wordpress日志后,發(fā)現(xiàn)debug
日志文件中報(bào)以下的錯(cuò)誤。開啟debug日志方法請(qǐng)移步歷史文章如何開啟WordPress調(diào)試模式(報(bào)錯(cuò)提示),將日志打印到wp-content
目錄下的debug.log
中。

網(wǎng)站查詢資料說:圖形驗(yàn)證碼功能需要安裝gd庫
和freetype
等依賴,通過phpinfo()查看到詳細(xì)信息里:gd擴(kuò)展沒有freetype
:
查看phpinfo()的方法
在網(wǎng)站的根目錄下新建一個(gè)php-info.php
的文件,內(nèi)容為:
<?php phpinfo();
保存后,用域名訪問,如https://action.liabio.cn/php-info.php
,即可看到。
docker編譯鏡像
Dockerfile文件如下:
FROM wordpress:4.9.8 RUN echo 'deb http://mirrors.163.com/debian/ stretch main contrib non-free\ndeb http://mirrors.163.com/debian/ stretch-updates main contrib non-free\ndeb http://mirrors.163.com/debian/ stretch-backports main contrib non-free' >?/etc/apt/sources.list RUN?apt?update?\ &&?apt?install?-y?libwebp-dev?libjpeg-dev?libpng-dev?libfreetype6-dev?\ &&?docker-php-source?extract?\ &&?cd?/usr/src/php/ext/gd?\ &&?docker-php-ext-configure?gd?--with-webp-dir=/usr/include/webp?--with-jpeg-dir=/usr/include?--with-png-dir=/usr/include?--with-freetype-dir=/usr/include/freetype2?\ &&?docker-php-ext-install?gd?\ &&?php?-m?|?grep?gd
執(zhí)行以下編譯命令:
docker?build?-t?wordpress-freetype:4.9.8?.
結(jié)果編譯報(bào)錯(cuò)。
docker編譯鏡像報(bào)錯(cuò)
OCI?runtime?create?failed:?container_linux.go:346:?starting?container?process?caused?"process_linux.go:319:?getting?the?final?child's?pid?from?pipe?caused?\"EOF\"":?unknown
因?yàn)槲沂褂玫氖?9.03.5版本的docker,在網(wǎng)上查了資料,大致意思是需要18版本的docker編譯才不會(huì)報(bào)錯(cuò)。
果然,18版本的docker編譯沒有報(bào)錯(cuò):
使用集成了freetype的新鏡像
使用新鏡像后,可以看到freetype成功集成。
可以看到二維碼已經(jīng)成功的顯示出來了。
