创建 Linkedin 图片 ugcPost 在从本地主机而不是从 AWS ECS 发布时有效

Question

我正在按照此处的文档在我的 java 应用中的公司简介中创建图像共享 --->https://docs.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/share-on-linkedin#create-an-image-share

我遇到的问题是，从 AWS ECS FARGATE 容器成功上传文件（我得到 201）后，posting 从本地主机成功。这是我的代码：

  String mediaUploadResponse = registerMediaUpload(userId, headers);
        JsonNode mediaUpload = objectMapper.readTree(mediaUploadResponse);
        String uploadUrl = mediaUpload.findPath("uploadUrl").asText();

        HttpClient client = HttpClientBuilder.create().build();
        HttpPut request = new HttpPut(uploadUrl);
        request.addHeader("Content-Type", APPLICATION_OCTET_STREAM_VALUE);
        request.setHeader("X-Restli-Protocol-Version", "2.0.0");
        request.setHeader("Authorization", requireNonNull(headers.get(AUTHORIZATION)).get(0));
        Path tempFilePath = Files.createTempFile("linkedin", null);
        try (InputStream fileStream = new URL(fileUrl).openStream()) {
            Files.write(tempFilePath, fileStream.readAllBytes());
            File tempFile = tempFilePath.toFile();
            request.setEntity(new FileEntity(tempFile, IMAGE_PNG));
            HttpResponse response = client.execute(request);

            if (response.getStatusLine().getStatusCode() == 201) {
                log.info("------------------- media upload result {}", response.getEntity());
                return mediaUpload;
            } else {
                log.error("linkedin media upload request failed {}", request);
                throw new BadRequestException(response.toString());
            }
        } finally {
            boolean deleted = tempFilePath.toFile().delete();
            log.info("------------------- tempfile deleted: {}", deleted);
        }

mediaUpload是调用POST https://api.linkedin.com/v2/assets?action=registerUpload

注册媒体上传得到的结果

我正在使用 /v2/assets/{asset-id} 检查资产状态，我最终得到：

{
    "recipes": [
        {
            "recipe": "urn:li:digitalmediaRecipe:feedshare-image",
            "status": "CLIENT_ERROR"
        }
    ],
    "serviceRelationships": [
        {
            "relationshipType": "OWNER",
            "identifier": "urn:li:userGeneratedContent"
        }
    ],
    "mediaTypeFamily": "STILLIMAGE",
    "created": 1588963432407,
    "id": "C4D22AQGIhdXwlSvDZQ",
    "lastModified": 1588963433173,
    "status": "ALLOWED"
}

但是当来自本地主机的运行一切正常时，post 出现在公司提要中。

真的很难理解可能是什么问题。

我实际上设法同时解决了这个问题。问题是由于 fileUrl 是一个 link 到 s3 存储桶中的文件 link 作为我可以直接访问的云端部署的来源。所以我使用 AmazonS3 s3client 直接获取输入流。
