预签名 URL 的 Localstack PUT 对象的内容长度为零

Question

在集成测试中使用“localstack/localstack:3.0.2”时（通过 TestContainers） 我通过 SDK JAVA (kotlin) 生成预签名 url

fun getPresignedPutUrl(bucket: String, key: String): String {
        val putRequest = PutObjectRequest.builder()
            .bucket(bucket)
            .key(key)
            .build()

        val presignedPutRequest = PutObjectPresignRequest.builder()
            .signatureDuration(putExpiration) // The URL expires in 10 minutes.
            .putObjectRequest(putRequest)
            .build()

        val url = s3presigner.use { it.presignPutObject(presignedPutRequest) }
        return url.url().toExternalForm()
    }

生成的 url 用于从 Spring RestTemplate (groovy) 上传

void putFileToPresignedUrl(Resource resource, String presignedUrl) {
        def decodedUri = URLDecoder.decode(presignedUrl, StandardCharsets.UTF_8.toString())
        def headers = new HttpHeaders().tap {
            setContentType(MediaType.MULTIPART_FORM_DATA)
        }
        final def body = new LinkedMultiValueMap<>().tap {
            set("file", resource)
        }
        def httpEntity = new HttpEntity(body, headers)

        rest.put(decodedUri, httpEntity)
    }

日志中没有太多内容，但检查 localstack 会大喊： AWS s3.PutObject => 200

之后，使用aws cli

aws s3api --endpoint-url=http://localhost:52552 get-object --key theFile.json --bucket thetenant1 ~/Downloads/theFile.json

我得到了

{
            "Key": "theFile.json",
            "LastModified": "2023-12-28T22:47:14+00:00",
            "ETag": "\"d41d8cd98f00b204e9800998ecf8427e\"",
            "Size": 0,
            "StorageClass": "STANDARD",
            "Owner": {
                "DisplayName": "webfile",
                "ID": "75aa57f09aa0c8caeab4f8c24e99d10f8e7faeebf76c078efc7c6caea54ba06a"
            }
        }

如果大小为0，获取对象会给出空（零大小）文件

我错过了什么吗？这些都是 github localstack 中的旧错误（全部关闭），抱怨同样。

嗯，localstack/localstack:3.0.2 的临时错误。最新标签解决了问题:-(
