如何高效地在Laravel应用中处理外部API的JSON响应

use Illuminate\Support\Facades\Http;

$response = Http::post('http://localhost/imageresizer/service.php', [
    // ... 请求参数 ...
]);

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;
use Illuminate\Support\Facades\Storage;

class ImageController extends Controller
{
    public function processImage()
    {
        $imageFileName = 'img.jpg';
        $imagePath = Storage::path('public/images/' . $imageFileName);

        if (!file_exists($imagePath)) {
            // 处理文件不存在的情况
            return response()->json(['error' => 'Image file not found.'], 404);
        }

        try {
            $response = Http::attach(
                'new_file',
                file_get_contents($imagePath),
                'new_file.jpg'
            )->post('http://localhost/imageresizer/service.php', [
                'sizes[0][new_width]' => 400,
                'sizes[0][new_height]' => 200,
                'sizes[1][new_width]' => 300,
                'sizes[1][new_height]' => 500,
            ]);

            // 检查响应是否成功
            if ($response->successful()) {
                // 使用 $response->json() 直接获取解析后的JSON数据
                $data = $response->json();

                // 现在可以像访问数组一样访问数据
                // 例如：$data['status'], $data['zip name'], $data['link']
                dd($data); // 打印解析后的数组内容
            } else {
                // 处理API返回的错误
                $errorMessage = $response->json('message') ?? $response->body();
                return response()->json(['error' => 'API request failed: ' . $errorMessage], $response->status());
            }
        } catch (\Exception $e) {
            // 处理网络请求异常
            return response()->json(['error' => 'Network request error: ' . $e->getMessage()], 500);
        }
    }
}

<?php

// 假设这里进行了图片处理，并生成了zip文件
$zipname = 'processed_images_' . time() . '.zip'; // 示例zip文件名

// 构造响应数据
$responsePayload = [
    'status' => http_response_code(), // 获取当前HTTP状态码，例如200
    'zip_name' => basename($zipname),
    'link' => 'http://localhost/imageresizer/zip/' . basename($zipname)
];

// 设置Content-Type头部为application/json
header("Content-Type: application/json");

// 将数据编码为JSON字符串并输出
echo json_encode($responsePayload);

// 确保在输出JSON后不再有其他输出，避免JSON格式损坏
exit();

// 在Laravel API控制器中
public function myApiEndpoint()
{
    $dataToBeSent = [
        'status' => 200,
        'message' => 'Operation successful',
        'result' => ['item1', 'item2']
    ];
    return response()->json(['data' => $dataToBeSent], 200);
}

$data = $response->json();

// 访问状态
$status = $data['status']; // 例如：200

// 访问zip文件名
$zipName = $data['zip_name']; // 例如：processed_images_1678901234.zip

// 访问下载链接
$downloadLink = $data['link']; // 例如：http://localhost/imageresizer/zip/processed_images_1678901234.zip

echo "Status: " . $status . "\n";
echo "Zip Name: " . $zipName . "\n";
echo "Download Link: " . $downloadLink . "\n";
