Nginx使用ngx-http-auth-jwt-module验证JWT失败：解析错误码22

我在Nginx层面使用ngx-http-auth-jwt-module验证JWT令牌时，Nginx日志持续出现「failed to parse JWT, error code 22」错误。以下是测试情况：

• 自定义密钥搭配自定义令牌：无法通过验证
• 模块官方提供的密钥搭配对应令牌：验证正常
• 模块官方提供的密钥搭配自定义令牌：无法通过验证

我分别尝试了HS256和RSA256两种密钥算法，均出现相同的解析失败错误。

我的Nginx配置 #

server {
    listen   443 ssl;
    server_name  auth.mylocaldev.com.com www.auth.mylocaldev.com.com;
    ssl_certificate        /etc/nginx/ssl/mylocaldev.crt;
    ssl_certificate_key    /etc/nginx/ssl/mylocaldev.key;    

location /hsa {
    proxy_pass https://mybackend.dev/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    proxy_set_header Host $host;
    proxy_set_header  X-Real-IP  $remote_addr;
    proxy_cache_bypass $http_upgrade;
    proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto $scheme;

       auth_jwt_enabled on;
       auth_jwt_key "00112233445566778899AABBCCDDEEFF00112233445566778899AABBCCDDEEFF";
       auth_jwt_algorithm HS256;
    }
}

无法通过验证的自定义令牌 #
