Homestead and NGINX error: emerg] invalid number of arguments in "proxy_set_header"

Question

我正在尝试将位置块添加到 NGINX 的默认配置中。我复制了 homestead/scripts/site-types/larave.sh 并添加了下面的代码块：

location ^~ /mysocket {
        #your proxy directives
        proxy_pass https://127.0.0.1:1234;
        proxy_redirect off;
        proxy_ssl_session_reuse on;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy false;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

结果：

nginx: [emerg] invalid number of arguments in "proxy_set_header" directive

完整代码：

有人能发现我犯的错误吗？当我删除 'location' 块时，代码工作正常。此代码在实时服务器上也运行没有任何问题。

问题是我没有转义新块中的变量。

location ^~ /mysocket {
        #your proxy directives
        proxy_pass https://127.0.0.1:1234;
        proxy_redirect off;
        proxy_ssl_session_reuse on;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy false;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection upgrade;
    }
