如何使用修改过的标头进行HTTP GET？

import requests

url = 'https://example.com'
headers = {'Custom-Header': 'Custom-Value'}

response = requests.get(url, headers=headers)

const axios = require('axios');

const url = 'https://example.com';
const headers = {'Custom-Header': 'Custom-Value'};

axios.get(url, {headers})
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class Main {
  public static void main(String[] args) throws Exception {
    URL url = new URL("https://example.com");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    connection.setRequestProperty("Custom-Header", "Custom-Value");

    int responseCode = connection.getResponseCode();
    System.out.println("Response Code: " + responseCode);

    try (BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
      String inputLine;
      StringBuilder content = new StringBuilder();
      while ((inputLine = in.readLine()) != null) {
        content.append(inputLine);
      }
      System.out.println(content.toString());
    }
  }
}

<?php
$url = 'https://example.com';
$headers = ['Custom-Header: Custom-Value'];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

echo $response;
?>
