Nginx“ 400请求标头或Cookie太大”问题

编程问答 2022-06-23

问题描述

我的springboot应用程序从nginx获得了400个Bad Request请求标头或cookie太大，因为JWT密钥为38.7kb。当我使用较小的JWT密钥时，一切都很好。我尝试通过在服务器上下文中添加nginx的配置来修改它。

    client_header_buffer_size 64k;
    large_client_header_buffers 4 64k;
    proxy_buffer_size   128k;
    proxy_buffers   4 256k;
    proxy_busy_buffers_size   256k;

不幸的是，nginx仍然返回相同的400 Bad Request。奇怪的是，我在nginx错误日志中找不到任何跟踪。我的操作系统是centOS 7.6，nginx版本是1.18.1。

这是我完整的nginx配置文件。
