我正在使用ubuntu。上面的网址显示 403 Forbidden 但如果我减少参数它工作正常

我的 php 设置是

upload_max_filesize = 200M
max_file_uploads = 200
max_execution_time = 240
max_input_time = 120
max_input_vars = 6000
memory_limit = 1G
post_max_size = 200M

有什么帮助吗？

403 Forbidden 错误表明服务器由于请求的长度而拒绝该请求。但在 PHP 中，查询字符串本身的长度没有具体限制。相反，限制通常是由网络服务器和浏览器施加的。

我不确定你有 Apache 还是 Nginx。那么，让我为您更新两者的最新情况。

如果您使用 Apache：

Apache 有一个名为 LimitRequestLine 的指令，用于设置 HTTP 请求行大小的限制。默认限制为 8190 字节（大约 8190 个字符）。要更改此限制，您可以在 Apache 配置文件中添加或修改 LimitRequestLine 指令：

LimitRequestLine 16384

重新启动 Apache 服务器

sudo systemctl restart apache2

如果您使用 Nginx：
打开 Nginx 配置文件，通常位于：

 /etc/nginx/nginx.conf

添加或更新large_client_header_buffers指令以为您的标头分配更大的缓冲区：

http {
    large_client_header_buffers 4 16k;
    ...
}

重启Nginx

sudo systemctl restart nginx

之后，您应该能够处理更长的查询字符串，而不会遇到 403 Forbidden 错误。
