- ChatGPT官方API文档:https://beta.openai.com/docs/api-reference/introduction
- PHP调用API的方法:
//设置请求URL和参数
$url = 'https://api.openai.com/v1/engines/davinci-codex/completions';
$headers = array(
'Content-Type: application/json',
'Authorization: Bearer your_api_key'
);
$data = array(
'prompt' => 'Hello',
'max_tokens' => 5,
'temperature' => 0.5,
);
//初始化curl
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//执行请求
$result = curl_exec($ch);
curl_close($ch);
//处理响应结果
$response = json_decode($result, true);
if ($response['object'] == 'error') {
echo 'API Error: ' . $response['error']['message'];
} else {
echo 'API Response: ' . $response['choices'][0]['text'];
}
注意事项:
1.需要先在ChatGPT官网注册并获取API Key;
2.需要在请求头中添加Authorization头,值为"Bearer your_api_key",其中your_api_key为您的API Key;
3.需要将请求参数转换为JSON格式,并在请求头中添加Content-Type头,值为"application/json";
4.响应结果也是JSON格式,需要进行解析。
