Homestead 和 NGINX 错误：新兴]"proxy_set_header"中的参数数无效

Question

我正在尝试将一个位置块添加到NGINX的默认配置中。我复制了homest/scripts/site-types/laravel.sh，并添加了以下代码块：

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：

#!/usr/bin/env bash
declare -A params=$6       # Create an associative array
declare -A headers=${9}    # Create an associative array
declare -A rewrites=${10}  # Create an associative array
paramsTXT=""
if [ -n "$6" ]; then
for element in "${!params[@]}"
do
paramsTXT="${paramsTXT}
fastcgi_param ${element} ${params[$element]};"
done
fi
headersTXT=""
if [ -n "${9}" ]; then
for element in "${!headers[@]}"
do
headersTXT="${headersTXT}
add_header ${element} ${headers[$element]};"
done
fi
rewritesTXT=""
if [ -n "${10}" ]; then
for element in "${!rewrites[@]}"
do
rewritesTXT="${rewritesTXT}
location ~ ${element} { if (!-f $request_filename) { return 301 ${rewrites[$element]}; } }"
done
fi
if [ "$7" = "true" ]
then configureXhgui="
location /xhgui {
try_files $uri $uri/ /xhgui/index.php?$args;
}
"
else configureXhgui=""
fi
block="server {
listen ${3:-80};
listen ${4:-443} ssl http2;
server_name .$1;
root "$2";
index index.html index.htm index.php;
charset utf-8;
$rewritesTXT

location / {
try_files $uri $uri/ /index.php?$query_string;
$headersTXT
}
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;
}

$configureXhgui
location = /favicon.ico { access_log off; log_not_found off; }
location = /robots.txt  { access_log off; log_not_found off; }
access_log off;
error_log  /var/log/nginx/$1-error.log error;
sendfile off;
location ~ .php$ {
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php$5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
$paramsTXT
fastcgi_intercept_errors off;
fastcgi_buffer_size 16k;
fastcgi_buffers 4 16k;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
}
location ~ /.ht {
deny all;
}
ssl_certificate     /etc/nginx/ssl/$1.crt;
ssl_certificate_key /etc/nginx/ssl/$1.key;
}
"
echo "$block" > "/etc/nginx/sites-available/$1"
ln -fs "/etc/nginx/sites-available/$1" "/etc/nginx/sites-enabled/$1"

有人能发现我犯的错误吗？当我删除"位置"块时，代码运行良好。此代码也在实时服务器上运行，没有任何问题。

Answer 1

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;
}

Answer 2

您必须在每行的末尾使用分号(；(。例如，以下代码有错误：

proxy_set_header Content-Type "text/xml; charset=utf-8"
proxy_set_header Connection keep-alive;

但这是正确的：

proxy_set_header Content-Type "text/xml; charset=utf-8";
proxy_set_header Connection keep-alive;
