使用 @aws-sdk/client-s3 将图像上传到 amazon s3 并获取其位置

Question

我正在尝试将图像文件上传到 s3，但收到此错误消息：

ERROR: MethodNotAllowed: The specified method is not allowed against this resource.

我的代码使用@aws-sdk/client-s3 包上传此代码：

const s3 = new S3({
    region: 'us-east-1',
    credentials: {
        accessKeyId: config.accessKeyId,
        secretAccessKey: config.secretAccessKey,
    }
});

exports.uploadFile = async options => {
    options.internalPath = options.internalPath || (`${config.s3.internalPath + options.moduleName}/`);
    options.ACL = options.ACL || 'public-read';

    logger.info(`Uploading [${options.path}]`);
    const params = {
        Bucket: config.s3.bucket,
        Body: fs.createReadStream(options.path),
        Key: options.internalPath + options.fileName,
        ACL: options.ACL
    };

    try {
        const s3Response = await s3.completeMultipartUpload(params);
        if (s3Response) {
            logger.info(`Done uploading, uploaded to: ${s3Response.Location}`);
            return { url: s3Response.Location };
        }
    } catch (err) {
        logger.error(err, 'unable to upload:');
        throw err;
    }
};

我不确定这个错误是什么意思，一旦文件上传，我需要在 s3 中获取他的位置

感谢您的帮助

要上传单个图像文件，您需要调用s3.upload() 而不是s3.completeMultipartUpload()。

如果您有非常大的文件并想分多个部分上传，则工作流程如下所示：

s3.createMultipartUpload()
s3.uploadPart()
s3.uploadPart()
...
s3.completeMultipartUpload()

查看official documentation，看起来在 JavaScript SDK 中进行简单 S3 上传的新方法是这样的：

s3.send(new PutObjectCommand(uploadParams));
