这让我一直很沮丧。我一直在听那句经典台词:
请求的上不存在“access control allow origin”头
资源。
我正在ubuntu 16.04上运行最新的稳定nginx,配置了一个swoole服务器来处理php 7.2中的laravel php请求。据我所知一切都在起作用。
laravel api在一个子域上,前端是另一个子域上的一个角。到目前为止一切正常,所以我一直在尝试在后端站点上配置cors。
尽管配置了它,但它并不识别存在。是的,我每次更新配置时都重新启动nginx。出于开发目的,缓存目前处于关闭状态。nginx配置缩短如下:
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server {
listen 80;
listen [::]:80;
root /var/www/sub.example.com/;
index index.php;
server_name sub.example.com www.sub.example.com;
[redirect 301 part]
[php location]
}
## https://example.com redirects to https://www.example.com
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name www.sub.example.com;
[SSL certs]
[redirect 301 to sub.example.com]
}
## Serves https://sub.example.com
server {
server_name lhb.luminuxlab.com;
listen 443 ssl http2 ;
listen [::]:443 ssl http2;
[SSL certs]
root /var/www/sub.example.com;
index index.php;
location / {
try_files $uri $uri/ /index.php?@swoole;
}
[php stuff]
location @swoole {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow_Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Ra$
add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
proxy_set_header Host $http_host;
proxy_set_header Scheme $scheme;
proxy_set_header SERVER_PORT $server_port;
proxy_set_header REMOTE_ADDR $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
# IF https
proxy_set_header HTTPS "on";
proxy_pass http://127.0.0.1:1215$query_string;
}
}
我试着把标题移到很多不同的地方,但是我没能在响应中得到改变,用curl ping服务器
curl -H "Access-Control-Request-Method: GET" -H "Origin: http://front.example.com" --head http://back.example.com/
没有提供有用的信息,cors头似乎不包括在内。我试过cors头命令的不同变体和配置,但没有响应。
有人知道会出什么事吗?
