從AWS-S3獲取文件

Question

我在S3存儲桶中有文件（PDF和圖像），我正在嘗試使用下載

bucket.getObject(params, function(err, data)

我正在Uint8Array中獲取數據，如何將其作為文件獲取？

在該文件的AWS屬性中：

Content-Disposition : inline
Content-Type : application/pdf

碼：

const params = {
  Bucket: 'mts-test-procedure-document',
  Key: 'Key'

};

bucket.getObject(params, function(err, data){
  if (err) {
    console.log('There was an error getting your file: ', err);
    return false;
  }

  console.log('Successfully got file.', data);
  // return true;
});  

安慰：

Answer 1

您需要在上傳文件時進行定義。 對於圖像

    Content-Type: "image/jpeg"

用於jpeg圖像

對於pdf：

 Content-Type: "application/pdf"
 Content-Disposition: inline;
