Nginx反代MinIO后，上传文件签名异常 很早之前自己搭建了一个MinIO对象存储服务，使用Nginx进行反代，但是使用SpringBoot对接的时候，上传文件总是报错。错误内容The request signature we calculated does not match the signature you provided. Check your key and signing method.错误内容大概是因为Nginx反代后请求签名与您提供的签名不匹配。Nginx配置文件我的配置文件server { listen 80; server_name minio.home.com; client_max_body_size 20M; #PROXY-START/ location / { proxy_pass http://127.0.0.1:9000/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header REMOTE-HOST $remote_addr; add_header X-Cache $upstream_cache_status; # Set Nginx Cache add_header Cache-Control no-cache; expires 12h; } #PROXY-END/ }修改为官方的配置文件即可解决此问题server { listen 80; server_name minio.home.com; client_max_body_size 20M; #PROXY-START/ location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_connect_timeout 300; # Default is HTTP/1, keepalive is only enabled in HTTP/1.1 proxy_http_version 1.1; proxy_set_header Connection ""; chunked_transfer_encoding off; proxy_pass http://localhost:9000; # If you are using docker-compose this would be the hostname i.e. minio # Health Check endpoint might go here.
