Google Cloud SDK-Anfrage an Vertex AI, Fehler 503 zurückgegeben ⇐ Php

[Guest]

Ich implementieren die Vorhersage-IA-Dienste, indem ich PHP SDK für die Google Cloud-Plattform verwende, aber wenn ich die Anfrage mache, gibt der Dienst 503 UNAVAILABLE Code 14 zurück, aber wenn ich eine Curl-Petition verwende, um das Gleiche zu testen, werden gute Ergebnisse zurückgegeben.
Ich verwende den Beispielcode

Code: Select all

function generate_content_sample(string $model): void
{
$predictionServiceClient = new PredictionServiceClient();

$contentsParts = new Part();
$contentsParts->setText("loremp ipsum");

$contentsParts = [new Part()];
$content = (new Content())
->setRole('user')
->setParts($contentsParts);

$contents = [$content,];
$request = (new GenerateContentRequest())
->setModel($model)
->setContents($contents);

try {
$response = $predictionServiceClient->generateContent($request);
printf('Response data: %s' . PHP_EOL, $response->serializeToJsonString());
} catch (ApiException $ex) {
printf('Call failed with message: %s' . PHP_EOL, $ex->getMessage());
}
}

Ergebniscode

Code: Select all

Call failed with message: {
