AWS Lambda@Edge Redirect / Add Custom Header

Viewer Request, Origin Request 둘 다 동작

(Viewer Req의 경우 캐싱 동작)

'use strict';


/* This is an origin request function */
exports.handler = (event, context, callback) => {
    /*
     * Generate HTTP redirect response with 301 status code and Location header based on region.
     */
    const request = event.Records[0].cf.request;
    const request_uri = request.uri;
    const host = request.headers.host[0].value
    const path = "/kr/img.jpg"
    
    if(request_uri != "/test"){
        return callback(null, request)
    }
    
    console.log('https://' + host + path)

    const response = {
        status: '302',
        statusDescription: 'Found',
        headers: {
            location: [{
                key: 'Location',
                value: 'https://' + host + path,
            }],
        },
    };


    callback(null, response);
};

 

Viewer Response 커스텀 헤더 추가

'use strict';
exports.handler = (event, context, callback) => {
   console.log('Adding additional headers to CloudFront response.');

   const response = event.Records[0].cf.response;
   
   response.headers['strict-transport-security'] = [{
      key: 'Strict-Transport-Security',
      value: 'max-age=86400',
   }];
   
   response.headers['custom-header'] = [{
      key: 'custom-header',
      value: 'lambda-edge',
   }];
   
   response.headers['leedoing'] = [{
      key: 'leedoing',
      value: 'test',
   }]


   callback(null, response);
};
