Die Gesamtanzahl der Chunks ist ungültig, wenn Videos zur Veröffentlichung auf Tiktok mithilfe der Tiktok-API in Laravel ⇐ Php

[Guest]

Beim Veröffentlichen von kleinen Videos mit 3 MB und 2 MB funktioniert es gut, solange es nicht in Stücke aufgeteilt wird, d. h. weniger als 5 MB, und die totalchunks-Variable gleich 1 ist, wie Sie im Code unten sehen können. Wenn Sie jedoch zu größeren Videos wechseln, bei denen Sie etwa 28 MB in Stücke schneiden müssen, wird dies angezeigt Ich erhalte diesen Fehler: Die Gesamtanzahl der Blöcke ist ungültig

Code: Select all

{
"success": false,
"error": "Failed to upload video: Client error: `POST https://open.tiktokapis.com/v2/post/publish/video/init/` resulted in a `400 Bad Request` response:\n{\"error\":{\"code\":\"invalid_params\",\"message\":\"The total chunk count is invalid\",\"log_id\":\"2025012015022992B6C5AD85BB021DC (truncated...)\n",
"publish_id": null
}

So berechnen Sie die Blockgröße eines Videos, das ich in public/videos gespeichert habe

Code: Select all

  // Get video from public folder
$videoPath = public_path('videos/xyz.mp4');
if (!file_exists($videoPath)) {
return response()->json([
'success' => false,
'error' => 'Video file not found in public/videos folder'
], 404);
}

// Calculate video parameters with TikTok specs
$videoSize = (int)filesize($videoPath);
$minChunkSize = 5 * 1024 * 1024; // 5MB minimum
$maxChunkSize = 64 * 1024 * 1024; // 64MB maximum

// Handle small videos ( 300]);

// Initialize video upload
$initResponse = $client->post('https://open.tiktokapis.com/v2/post/publish/video/init/', [
'headers' => [
'Authorization' => 'Bearer ' .  $usertiktok->access_token,
'Content-Type' => 'application/json'
],
'json' => [
'source_info' => [
'source' => 'FILE_UPLOAD',
'video_size' => $videoSize,
'chunk_size' => $chunkSize,
'total_chunk_count' => $totalChunks
],
'post_info' => [
'title' => $request->title,
'description' => $request->description ?? '',
'privacy_level' => $request->privacy_level,
'disable_duet' => false,
'disable_comment' => false,
'disable_stitch' => false
]
]
]);

und das ist vollständiger Code

Code: Select all

    public function uploadVideo(Request $request)
{
$account_id = auth()->user()->account_id;
$user_id = $request->user_id;

// Get video from public folder
$videoPath = public_path('videos/xyz.mp4');
if (!file_exists($videoPath)) {
return response()->json([
'success' => false,
'error' => 'Video file not found in public/videos folder'
], 404);
}

// Calculate video parameters with TikTok specs
$videoSize = (int)filesize($videoPath);
$minChunkSize = 5 * 1024 * 1024; // 5MB minimum
$maxChunkSize = 64 * 1024 * 1024; // 64MB maximum

// Handle small videos ( 4 * 1024 * 1024 * 1024) { // 4GB max
return response()->json([
'success' => false,
'error' => 'Video size must be less than 4GB'
], 400);
}

// Validate chunk count
if ($totalChunks > 1000) {
return response()->json([
'success' => false,
'error' => 'Invalid chunk count. Must be maximum 1000'
], 400);
}

// Validate request
$request->validate([
'title' => 'required|string|max:150',
'description' => 'nullable|string|max:2200',
'privacy_level' => 'required|in:PUBLIC_TO_EVERYONE,MUTUAL_FOLLOW_FRIENDS,SELF_ONLY',

$usertiktok = User::where("id", $user_id)

if (!$usertiktok) {

Ich habe versucht, die Variable $totalChunks so zu ändern, dass sie statisch auf 1 ist, aber es wird mir ein anderer Fehler angezeigt

Code: Select all

{
"success": false,
"error": "Failed to upload video: Client error: `POST https://open.tiktokapis.com/v2/post/publish/video/init/` resulted in a `400 Bad Request` response:\n{\"error\":{\"code\":\"invalid_params\",\"message\":\"The chunk size is invalid\",\"log_id\":\"20250120150836CF3EDDD9FB5BFC1C0A85\"}}\n",
"publish_id": null
}

Ich habe alles gemäß dieser Dokumentation befolgt und es funktioniert immer noch nicht. Bitte kann jemand mit Erfahrung im Veröffentlichen mit der Tiktok-API helfen?
