OpenAI GPT-3 API 错误：“您没有提供 API 密钥。您需要使用承载身份验证在授权标头中提供 API 密钥”

我收到以下 PHP 代码的错误：

$curl = curl_init("https://api.openai.com/v1/engines/davinci/completions");

$data = array(
  'prompt' => 'how many sundays in 2023',
  'max_tokens' => 256,
  'temperature' => 0.7,
  'model' => 'text-davinci-003'
);

curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Authorization: Bearer sk-MY-API-KEY']);
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);

$result = curl_exec($curl);
curl_close($curl);

$result = json_decode($result);
print $result->choices[0]->text;

我正确提供了 API 密钥，但收到此错误：

错误消息：您没有提供 API 密钥。您需要使用 Bearer auth 在 Authorization 标头中提供 API 密钥（即 Authorization：Bearer YOUR_KEY）

Problem

All 引擎API端点已弃用。

Solution

Use the 完成 API端点。

从此更改 URL...

https://api.openai.com/v1/engines/davinci/completions

……对此。

工作示例

如果你跑test.phpOpenAI API 将返回以下完成信息：

字符串（23）“

这确实是一个考验”

test.php

<?php
    $ch = curl_init();

    $url = 'https://api.openai.com/v1/completions';

    $api_key = 'sk-xxxxxxxxxxxxxxxxxxxx';

    $post_fields = '{
        "model": "text-davinci-003",
        "prompt": "Say this is a test",
        "max_tokens": 7,
        "temperature": 0
    }';

    $header  = [
        'Content-Type: application/json',
        'Authorization: Bearer ' . $api_key
    ];

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error: ' . curl_error($ch);
    }
    curl_close($ch);

    $response = json_decode($result);
    var_dump($response->choices[0]->text);
?>
