java调用wordpress插件扩展接口

添加WordPress REST API 插件

WordPress REST API 插件

添加JWT Authentication for WP-API 插件

JWT Authentication for WP-API 插件

修改wordpress容器的配置文件

vim wp-config.php

/* 增加JWT支持  */
define('JWT_AUTH_SECRET_KEY', 'u|0jBWAgY>Jl|A3+.&K1.}9{;K<cUs/%|2p5.akJO5UEcU^~dmkhAnwXk_J|$=dg');
define('JWT_AUTH_CORS_ENABLE', true);

修改容器文件

vim /var/www/html/wp-content/plugins/jwt-authentication-for-wp-rest-api/public/class-jwt-auth-public.php

添加一行如下内容
if (!$auth) {
        $allHeaders = getallheaders();
        $auth = isset($allHeaders['Authorization']) ? $allHeaders['Authorization'] : false;
    }

修改.htaccess为

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
php_value upload_max_filesize 128M
php_value post_max_size 128M
php_value max_execution_time 300

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]
</IfModule>
