php 训练本地知识库并与chatgpt api集成 demo
以下是一个使用PHP训练本地知识库并与ChatGPT API集成的示例代码:
<?php
// ChatGPT API的访问密钥
$api_key = 'your-api-key';
// ChatGPT API的URL
$api_url = 'https://api.openai.com/v1/chat/completions';
// 训练本地知识库的问题和回答
$knowledge_base = [
[
'question' => 'What is the capital of France?',
'answer' => 'The capital of France is Paris.'
],
[
'question' => 'Who is the author of "Pride and Prejudice"?',
'answer' => 'The author of "Pride and Prejudice" is Jane Austen.'
]
];
// 训练本地知识库
function trainKnowledgeBase($knowledge_base) {
$prompt = '';
foreach ($knowledge_base as $qa) {
$prompt .= 'Q: ' . $qa['question'] . '\n';
$prompt .= 'A: ' . $qa['answer'] . '\n\n';
}
return $prompt;
}
// 使用ChatGPT API获取回答
function getAnswerFromChatGPT($prompt, $api_key, $api_url) {
$data = array(
'prompt' => $prompt,
'max_tokens' => 100,
'temperature' => 0.6,
'n' => 1
);
$headers = array(
'Content-Type: application/json',
'Authorization: Bearer ' . $api_key
);
$ch = curl_init($api_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
curl_close($ch);
return json_decode($response, true)['choices'][0]['text'];
}
// 训练本地知识库并获取回答
$prompt = trainKnowledgeBase($knowledge_base);
$question = 'What is the capital of France?';
$prompt .= 'Q: ' . $question . '\n';
$answer = getAnswerFromChatGPT($prompt, $api_key, $api_url);
echo 'Answer: ' . $answer;
这个示例代码首先定义了ChatGPT API的访问密钥和URL。然后,它创建了一个包含问题和回答的本地知识库。trainKnowledgeBase函数将本地知识库的问题和回答组合成一个prompt字符串。
getAnswerFromChatGPT函数使用ChatGPT API发送请求,并返回API的回答。它将prompt、API密钥和API URL作为参数,并使用cURL库发送POST请求。
在示例代码的最后,我们使用训练好的本地知识库和ChatGPT API来获取问题"What is the capital of France?"的回答,并将其打印出来。
请确保将your-api-key替换为您自己的ChatGPT API访问密钥
