node.js - Node js s3fs 图片上传到 aws amazon s3 服务器并设置 ContentType

Question

下面是我的 Node javascript 代码，用于使用 s3fs 库将图像上传到 Amazon S3。图片已正确上传，但当我尝试在浏览器中查看该图片时，出现了下面提到的错误。

我检查了 Content-Type，它默认保存为 octet-stream。如果我手动将其设置为 image/jpeg 则该图像可以在浏览器中查看。谁能告诉我如何在仅上传或上传完成后设置内容类型？

我尝试设置 Content-Type 但它不适用于 S3fs 图片上传。

错误代码:-

<Error>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
</Error>

我的实际代码:-

    var AWS= require('aws-sdk');

    var fs = require('fs');

    var S3FS = require('s3fs');

    var s3fsImpl = new S3FS('bbqmobileimages/images/banners',{
        accessKeyId:'A********A',
        secretAccessKey:'****************'
    });

    var multiparty = require('connect-multiparty'),
        multipartyMiddleware = multiparty();

    router.use(multipartyMiddleware);

        router.post('/api/v1/backoffice/upload/image',function(req,res){

            console.log(JSON.stringify(req.files));
            var file = req.files;
            console.log("file",JSON.stringify(file))
            console.log("original name:- "+file.fileUpload.originalFilename);
            console.log("Path:- ",file.fileUpload.path);
            var stream = fs.createReadStream(file.fileUpload.path);
            return s3fsImpl.writeFile(file.fileUpload.originalFilename, stream).then(function(){
                fs.unlink(file.fileUpload.path, function(err){
                    console.error(err);
                })
                console.log("Sucessfully uploaded to Amazon S3 server");
            });
        });

尝试

s3fsImpl.writeFile(file.fileUpload.originalFilename, stream, {"ContentType":"image/jpg"})
