AWS S3 SDK 下載物件時強迫設定 Content-Disposition 為 attachment

 串AWS S3 SDK時

要下載一個項目，使用 Signature的下載方式

const getS3SignedDocumentURL = (docName) => {
  const url = s3.getSignedUrl('getObject', {
    Bucket: <aws-s3-bucket-name>,
    Key: <aws-s3-object-key>,
    Expires: <url-expiry-time>,
  });

  return url;
};

但會因為檔案預設的 Content-Type 被 Browser 處理(例如txt就直接打開)

所以需要指定一個 Content-Disposition

兩個方法

1.在網址後加上
String url = serverURL+'/'+bucketName+'/'+codedFilename+'?response-content-disposition='+EncodingUtil.urlEncode('attachment; filename=abc.doc','UTF-8')+'&AWSAccessKeyId='+awskey+'&Expires='+Lexpires+'&Signature='+codedsigned;

然後含這串signed的文字給後端去算signed

2.直接在Header裡加上ResponseContentDisposition: 原因是若後端已經拿算好的URI去計算Signed的話，只能靠在呼叫AWS s3 sdk 時加上ResponseContentDisposition

const getS3SignedDocumentURL = (docName) => {
  const url = s3.getSignedUrl('getObject', {
    Bucket: <aws-s3-bucket-name>,
    Key: <aws-s3-object-key>,
    Expires: <url-expiry-time>,
    ResponseContentDisposition: `attachment; filename="${docName}"`
  });

  return url;
};
