Linkedin v2 vector asset upload error 400

问题

Hello everyone who suffering from Microsoft LI v2 migration.

I have issue with UGC with vector asset (image), it's based on https://docs.microsoft.com/en-us/linkedin/marketing/integrations/community-management/shares/vector-asset-api#upload-the-asset

I have uploadUrl from the first query, and when i perform second query it gives me error 400. When i try to debug and cURL it (according to their example), the last log lines:

> Content-Length: 1636960
>
* Connection state changed (MAX_CONCURRENT_STREAMS updated)!
* We are completely uploaded and fine

* TLSv1.2 (IN), TLS alert, Client hello (1):
* Unexpected EOF
* Closing connection 0
curl: (56) Unexpected EOF

In the first query(registerUpload), I don't have desired headers from the first query:

-H "x-amz-server-side-encryption:aws:kms"
-H "x-amz-server-side-encryption-aws-kms-key-id:e10ace24-blah-4977-bar-89foo193e2ab"

Anyone had any luck with vector asset upload ?

回答1:

It was solved by adding 'Accept' => '*/*'(i experimented without it and it did not worked) and set request to multipart (ruby Faraday gem)

The vector asset documentation you referenced is specific to uploading video content to LinkedIn. You can view image share documentation at https://docs.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/share-on-linkedin?context=linkedin/consumer/context#create-an-image-share

From the documentation, you can register your upload:

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

{
"registerUploadRequest": {
    "recipes": [
        "urn:li:digitalmediaRecipe:feedshare-image"
    ],
    "owner": "urn:li:person:8675309",
    "serviceRelationships": [
        {
            "relationshipType": "OWNER",
            "identifier": "urn:li:userGeneratedContent"
        }
    ]
}

which returns the upload URL you can use to submit your image:

{
"value": {
    "uploadMechanism": {
        "com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest": {
            "headers": {},
            "uploadUrl": "https://api.linkedin.com/mediaUpload/C5522AQGTYER3k3ByHQ/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQJbrN86Zm265gAAAWemyz2pxPSgONtBiZdchrgG872QltnfYjnMdb2j3A&app=1953784&sync=0&v=beta&ut=2H-IhpbfXrRow1"
        }
    },
    "mediaArtifact": "urn:li:digitalmediaMediaArtifact:(urn:li:digitalmediaAsset:C5522AQGTYER3k3ByHQ,urn:li:digitalmediaMediaArtifactClass:feedshare-uploadedImage)",
    "asset": "urn:li:digitalmediaAsset:C5522AQGTYER3k3ByHQ"
}

}
