Code Examples in Python, PHP, and Node.js

This section provides examples of how to make API requests to the Movies API in different programming languages.

Query

This is the same moviesByTitle query shown in the Getting Started section. We will use this query in each of the programming language examples.

query {
  moviesByTitle (title: "Forrest Gump") {
    id
    title
    revenue
  }
}

Python Example

Python example using requests.

import requests
import json

api_key = "YOUR_API_KEY"  # Replace with your actual API key
endpoint_url = "https://jh-data.com/moviesapi/"
headers = {
    "Content-Type": "application/json",
    "X-API-Key": api_key
}
query = """
query {
  moviesByTitle (title: "Forrest Gump") {
    id
    title
    revenue
  }
}
"""
payload = {
    "query": query
}

response = requests.post(endpoint_url, headers=headers, json=payload)

if response.status_code == 200:
    json_response = response.json()
    print(json.dumps(json_response, indent=2)) # Pretty print the JSON response
else:
    print(f"Error: {response.status_code}")
    print(response.text)

JavaScript/Node.js Example

Node.js example using fetch API (Node.js v18+ or with fetch polyfill).

const apiKey = "YOUR_API_KEY"; // Replace with your actual API key
const apiUrl = "https://jh-data.com/moviesapi/";

const graphqlQuery = {
  query: `
    query {
      moviesByTitle (title: "Forrest Gump") {
        id
        title
        revenue
      }
    }
  `,
};

const headers = {
  "Content-Type": "application/json",
  "X-API-Key": apiKey,
};

fetch(apiUrl, {
  method: "POST",
  headers: headers,
  body: JSON.stringify(graphqlQuery), // Convert GraphQL query to JSON string
})
  .then((response) => {
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`); // Handle HTTP errors
    }
    return response.json(); // Parse JSON response
  })
  .then((data) => {
    // Pretty print the JSON response to the console for readability
    console.log(JSON.stringify(data, null, 2));
  })
  .catch((error) => {
    console.error("Error fetching data:", error); // Handle fetch errors
  });

If you are using a Node.js version older than v18, you might need to install node-fetch (a polyfill for fetch) using npm (npm install node-fetch), and then import it at the top of your JavaScript file:

const fetch = require('node-fetch'); // Import fetch for older Node.js

PHP Example

Make sure the curl extension is enabled in your PHP installation. It's usually enabled by default, but if not, you might need to uncomment or enable it in your php.ini configuration file (search for extension=curl).

<?php

$apiKey = "YOUR_API_KEY"; // Replace with your actual API key
$apiUrl = "https://jh-data.com/moviesapi/";

$graphqlQuery = [
    "query" => <<<GRAPHQL
        query {
          moviesByTitle (title: "Forrest Gump") {
            id
            title
            revenue
          }
        }
    GRAPHQL
];

$headers = [
    "Content-Type: application/json",
    "X-API-Key: " . $apiKey,
];

$postData = json_encode($graphqlQuery); // Encode GraphQL query to JSON

// Initialize cURL session
$ch = curl_init($apiUrl);

// Set cURL options
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return response as string
curl_setopt($ch, CURLOPT_POST, true);        // Set as POST request
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); // Set JSON request body
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);  // Set HTTP headers

// Execute cURL request
$response = curl_exec($ch);

// Check for cURL errors
if (curl_errno($ch)) {
    echo 'Curl error: ' . curl_error($ch);
} else {
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    if ($httpCode == 200) {
        $jsonResponse = json_decode($response, true); // Decode JSON response to PHP array

        if ($jsonResponse === null && json_last_error() !== JSON_ERROR_NONE) {
            echo 'JSON decode error: ' . json_last_error_msg();
        } else {
            echo "<pre>"; // Use <pre> for formatted output in HTML context if needed
            print_r($jsonResponse); // Or var_dump($jsonResponse); for debugging
            echo "</pre>";
        }
    } else {
        echo "HTTP error! status: " . $httpCode . "\n";
        echo "Response body:\n" . $response; // Output the response body for debugging
    }
}

// Close cURL session
curl_close($ch);
