我將 API 從一個子網域移到另一個子網域,而不影響已經執行的應用程式。我在 nginx 上配置了三台伺服器,例如:
原始API伺服器:
server {
listen 80;
server_name example.com;
root /var/www/example/;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?$args;
add_header 'Access-Control-Allow-Origin' '*';
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~*/api/([a-zA-Z0-9_]+) {
proxy_pass http://127.0.0.1:4343/api/$1;
proxy_read_timeout 60s;
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 'Access-Control-Allow-Origin' '*';
proxy_set_header 'Access-Control-Allow-Credentials' true;
}
...
}
代理透過伺服器:
server {
listen 4343;
server_name _;
root /var/www/exampleapi/;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?$args;
add_header 'Access-Control-Allow-Origin' '*';
location / {
try_files $uri $uri/ /index.php?$args;
}
...
}
AJAX 呼叫曾經在舊 api 上完美運行,但是對於新 api,我在 FF 上收到錯誤:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://example.com/api/startup. (Reason: CORS header 'Access-Control-Allow-Origin' does not match '*, *').
在 Safari 上:
XMLHttpRequest cannot load https://example.com/api/startup. Origin https://myclient.com is not allowed by Access-Control-Allow-Origin.
新舊 api 上的冰壺顯示:
HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
我該如何解決這個問題?

解決方案是不要為代理傳遞伺服器的 CORS 新增 add_header,因為這會重複標頭或使用 set_header
代理透過伺服器:
server {
listen 4343;
server_name _;
root /var/www/exampleapi/;
index index.php index.html index.htm;
try_files $uri $uri/ /index.php?$args;
location / {
try_files $uri $uri/ /index.php?$args;
}
...
}
