如何处理 KeyTooLongError Node.js(AWS)？

Question

我试图从我的 S3 服务器获取一些图像，但其中一些具有非常大的 URL。即使 URL 很大，我如何下载这些图像？

代码：

//download the object from the bucket
sourceS3.getObject(getparamsOrig, function(gerr, s3obj) {
    if (gerr) {
        //if there is problem just print to console and move on.
        console.log('Download issue');
        console.log(gerr);
        return;
    }   
});

调试：

DEBUG [03314cb6]    Download issue
DEBUG [03314cb6]    { [KeyTooLongError: Your key is too long]
DEBUG [03314cb6]      message: 'Your key is too long',
