PHP - google vision API -找不到类

Question

我在尝试使用google vision API时收到此错误消息

Fatal error: Uncaught Error: Class 'Google\Cloud\Vision\VisionClient' not found in C:\xampp\htdocs\index.php:7 Stack trace: #0 {main} thrown in C:\xampp\htdocs\index.php on line 7

我在windows上用的是xampp。我使用composer安装了Google api (以管理员身份)

composer require google/cloud-vision

我也运行(以admin身份)

composer install
composer update

google cloud sdk已安装。

这是我的代码

<?php
require 'C:\Users\MyUser\vendor\autoload.php';
use Google\Cloud\Vision\VisionClient;

$path = 'caption.jpg';

$vision = new VisionClient([
    'projectId' => 'my-project-numbers',
    'keyFilePath' => 'my-key.json'
]);

// Annotate an image, detecting faces.
$image = $vision->image(
    fopen($path, 'r'),
    ['text']
);

$tadaa = $vision->annotate($image);

echo '<pre>';
var_dump($tadaa->text());
echo '</pre>';

?>

Answer 1

根据官方文档，我建议使用这个php客户端库：

# imports the Google Cloud client library
use Google\Cloud\Vision\V1\ImageAnnotatorClient;

Quickstart: Using client libraries Vision Api

Answer 2

使用https://cloud.google.com/vision/docs/ocr中的代码

下面是index.php

<?php
namespace Google\Cloud\Samples\Vision;

use Google\Cloud\Vision\V1\ImageAnnotatorClient;

$path = 'caption.jpg';

    $imageAnnotator = new ImageAnnotatorClient();

    # annotate the image
    $image = file_get_contents($path);
    $response = $imageAnnotator->textDetection($image);
    $texts = $response->getTextAnnotations();

    printf('%d texts found:' . PHP_EOL, count($texts));
    foreach ($texts as $text) {
        print($text->getDescription() . PHP_EOL);

        # get bounds
        $vertices = $text->getBoundingPoly()->getVertices();
        $bounds = [];
        foreach ($vertices as $vertex) {
            $bounds[] = sprintf('(%d,%d)', $vertex->getX(), $vertex->getY());
        }
        print('Bounds: ' . join(', ', $bounds) . PHP_EOL);
    }

    $imageAnnotator->close();

?>

我还是得到了

Fatal error: Uncaught Error: Class 'Google\Cloud\Vision\V1\ImageAnnotatorClient' not found in C:\xampp\htdocs\index.php:8 Stack trace: #0 {main} thrown in C:\xampp\htdocs\index.php on line 8

这是composer.json

{
    "require": {
        "google/cloud-vision": "^1.2"
    }
}
