我需要将视频帖子成功上传到 LinkedIn 帐户，但我也无法从 LinkedIn 文档中理解这一点。我已经尝试了很多但没有成功。 请有成功上传V2视频的人帮忙。

Answer 1

嗨linkedin还没有发布视频上传。您可以使用文章EP（“shareMediaCategory”：“ARTICLE”）发送视频到linkedin

Answer 2

我使用LinkedIn API from Zoonman 来做客户端发布请求，但这超出了问题的范围。

因为我无法让 php curl 函数正常工作，所以我使用命令行界面来执行请求，它可以正常工作！请参阅下面的代码。

但是。甚至很难上传作品。当我请求获取上传状态时，它仍然是“WAITING_UPLOAD”。所以我认为@augustine jenin 是对的，它还不受支持。 （2019 年 5 月）

<?php
// first register upload
$data = [
	"registerUploadRequest" => [
		"recipes" => [
			"urn:li:digitalmediaRecipe:feedshare-video"
		],
		"owner" => "urn:li:organization:" . $liPageId,
		"serviceRelationships"=> [
			[
				"relationshipType"=> "OWNER",
				"identifier" => "urn:li:userGeneratedContent"
			]
		]
	]
];
    
$register = $client->post('assets?action=registerUpload', $data);

// get upload url and header
$uploadUrl = $register["value"]["uploadMechanism"]["com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest"]["uploadUrl"];
$headers = $register["value"]["uploadMechanism"]["com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest"]["headers"];
    
$curlHeaders = "";
foreach($headers as $htype => $header) {
	$curlHeaders .= ' -H "' . $htype . ':' . $header . '"';
}

// go upload the image to the url
$filePath = "/path/to/your/file";

$command = '/usr/bin/curl -v';
$command .= $curlHeaders;
$command .= ' --upload-file \'' . $filePath . '\' \'' . $uploadUrl . '\'';

// try it yourself by running this on the command line
//echo $command;

shell_exec($command);

?>
