Problem Description

nginx请求头长度过长报错缩短参数访问正常之前版本正常具体那个版本正常忘记了
请求头相同只是把参数长度缩短访问则正常
报错 502 nginx 报错日志 upstream prematurely closed connection while reading response header from upstream, client
但是确定后台服务没有问题

nginx报错日志

upstream prematurely closed connection while reading response header from upstream, client

请求头相同只是把参数长度缩短访问则正常
尝试过修改nginx参数

proxy_http_version 1.1;  
proxy_set_header Connection "";

或者

# 忽略 URL 编码校验（慎用）  
ignore_invalid_headers off;  
# 增加请求头缓冲区  
client_header_buffer_size 16k;  
large_client_header_buffers 4 64k;

或者

proxy_read_timeout 60s;    # 从上游读取响应超时时间
proxy_connect_timeout 30s; # 连接上游服务器的超时时间

或者

# 激进型缓冲区配置（需≥32G内存服务器）
client_header_buffer_size     128k;  # 基础头缓冲区扩容400%
large_client_header_buffers    16 256k; # 支持最大4MB头传输

# 必须同步调整的关联参数
http2_max_field_size          512k;    # HTTP/2头字段限制
proxy_buffer_size             256k;    # 代理缓冲同步扩容
client_max_body_size          1024m;   # 防止body与header竞争

等等各种尝试均没有起作用直接跳过nginx 直接访问后台服务则没问题之前历史版本没遇到过这个问题
服务部署好久了之前没问题但是有段时间没有用过所以不确定那个版本导致的问题
私聊我微信给你测试数据

商店中的 openresty 已经很久没有更新过版本了
1Panel 更新版本不会影响网站
你有具体的参数吗？

Do you have specific parameters?
