웹훅 설정

이걸 적용하지는 않았음

location /webhook/ {
    proxy_pass http://localhost:5678;
    add_header 'Access-Control-Allow-Origin' 'https://mywebsite.co.uk' always;
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
    add_header 'Access-Control-Allow-Headers' 'Content-Type' always;

Allowed Origins (CORS) error - Questions - n8n Community

Allowed Origins (CORS) error

 

 

웹훅 응답 CORS 설정

에러 :

Access to fetch at 'https://example.com/webhook/examplewebhook' from origin 
'https://example.com' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' 
header contains multiple values 'https://example.com,
*', but only one is allowed.

 

✔️해결!!!

아마도.. 응답이 이상한게? 와서 에러가 난듯.. 이렇게 설정해주면 숨겨줌

      # Hide CORS headers from the backend response
            proxy_hide_header 'Access-Control-Allow-Origin';
            proxy_hide_header 'Access-Control-Allow-Methods';
            proxy_hide_header 'Access-Control-Allow-Credentials';
            proxy_hide_header 'Access-Control-Allow-Headers';
