nginx無法獲取帶下劃線的header值的問題解決

Nginx默認(rèn)會將連字符轉(zhuǎn)換為下劃線,這可能會導(dǎo)致無法正確獲取到原始的請求頭值,本文主要介紹了nginx無法獲取帶下劃線的header值的問題解決,感興趣的可以了解一下

解決1. 啟用 underscores_in_headers

首先，確保在 HTTP 塊中啟用 underscores_in_headers 指令：

http {
    underscores_in_headers on;

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_host" "$http_xxl_sso_sessionid" ';

    access_log /var/log/nginx/access.log main;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    include /etc/nginx/conf.d/*.conf;
}

axios.interceptors.request.use(function (config) {
    // 在發(fā)送請求之前做些什么
    let token = localStorage.getItem("token");
    if (token != null && token != 'null') {
        config.headers["Xxl_sso_sessionid"] = token;
    }
    return config;
}, function (error) {
    // 對請求錯誤做些什么
    return Promise.reject(error);
});

這樣的話，如果前端這樣配置，后端可以直接獲取到header的值。

解決2

前端配置如下,nginx會自動轉(zhuǎn)換成下劃線,也就是xxl_sso_sessionid,就不需要開啟underscores_in_headers on

axios.interceptors.request.use(function (config) {
    // 在發(fā)送請求之前做些什么
    let token = localStorage.getItem("token");
    if (token != null && token != 'null') {
        config.headers["Xxl-sso-sessionid"] = token;
    }
    return config;
}, function (error) {
    // 對請求錯誤做些什么
    return Promise.reject(error);
});

nginx配置

http {

    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_host" "$http_xxl_sso_sessionid" ';

    access_log /var/log/nginx/access.log main;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    include /etc/nginx/conf.d/*.conf;

    upstream takeout-back-api {
        server localhost:10086 weight=1;
    }

    upstream order-back-api {
        server 8.141.87.136:10000 weight=1;
    }

    server {
        listen 443 ssl;
        server_name www.domain.com;
        ssl_certificate xxx.cn_bundle.crt;
        ssl_certificate_key xxx.cn.key;
        ssl_session_timeout 5m;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
        ssl_prefer_server_ciphers on;

        location / {
            root /usr/share/nginx/order-ui/dist;
            index index.html index.htm;
            try_files $uri $uri/ /index.html;
        }

        location /member {
            proxy_pass http://takeout-back-api;
        }

        location /order {
            proxy_set_header xxl_sso_sessionid $http_xxl_sso_sessionid;
            proxy_pass http://order-back-api;
        }
    }
}
