最近chatGPT和百度文心一言火的不得了，今天藤設計也整好在使用ChatGPT開發(fā)應用項目，給大家分享一段PHP請求api的代碼，希望對開發(fā)人員有用。
注：該php文件需部署在海外空間或服務器上使用，不能在國內服務器上運行。

<?php
define('OPENAI_API_KEY', '這里輸入您的key秘鑰');
$prompt = $_GET['prompt'];
$response = sendPostRequest($prompt);
echo $response;

function sendPostRequest($prompt) {
    $curl = curl_init();

    curl_setopt_array($curl, array(
      CURLOPT_URL => "https://api.openai.com/v1/completions",
      CURLOPT_RETURNTRANSFER => true,
      CURLOPT_ENCODING => "",
      CURLOPT_MAXREDIRS => 10,
      CURLOPT_TIMEOUT => 0,
      CURLOPT_FOLLOWLOCATION => true,
      CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
      CURLOPT_CUSTOMREQUEST => "POST",
      CURLOPT_POSTFIELDS => json_encode(array(
          "prompt" => $prompt,
          "max_tokens" => 2048,
          "model" => "text-davinci-003"
      )),
      CURLOPT_HTTPHEADER => array(
        "Content-Type: application/json",
        "Authorization: Bearer " . OPENAI_API_KEY
      ),
    ));

    $response = curl_exec($curl);

    curl_close($curl);
    return $response;
}
?>

以上代碼保存為index.php存放到您海外空間或服務器里即可運行

在瀏覽器里輸入index.php?prompt=請問有外星人嗎？

你就可以看到openai回答的內容了！
