题意：从 OpenAI 库中获取内容输出
问题背景：
I prepare integration openAI API with Codeigniter 4, for this I use library:
我准备将 OpenAI API 集成到 Codeigniter 4 中，为此我使用了以下库：
https://github.com/orhanerday/open-ai
I write controller CI4: 我编写了 CI4 控制器：
public function openAIPost(){$response = array();if ($this->request->getMethod() === 'post'){question = $this->request->getPost('question');$open_ai_key = getenv('OPENAI_API_KEY');$open_ai = new OpenAi($open_ai_key);$complete = $open_ai->chat(['model' => 'gpt-3.5-turbo','messages' => [["role" => "user","content" => $question]],'temperature' => 1.0,'max_tokens' => 10,'frequency_penalty' => 0,'presence_penalty' => 0,]);$response['complete'] = $complete;}echo json_encode($response);
}But I get in output: 但我在输出中得到：
{"id": "chatcmpl-6xxhQ2FLm08VhE8KKHsTpilkvpMTS","object": "chat.completion","created": 1679748856,"model": "gpt-3.5-turbo-0301","usage": {"prompt_tokens": 9,"completion_tokens": 10,"total_tokens": 19},"choices": [{"message": {"role": "assistant","content": "This is a test of the AI language model."},"finish_reason": "length","index": 0}]}How to get only content from response?
如何仅从响应中获取内容？
问题解决：
You should all you need in the JSON response returned by the OpenAI API you have.
你所需要的一切都在你收到的 OpenAI API 返回的 JSON 响应中。
You should navigate the JSON object and extract the message content using the following line.
你应该遍历 JSON 对象，并使用以下代码行提取消息内容。
$content = $complete.choices[0].message.content
it should give you "This is a test of the AI language model."
它应该返回给你 “This is a test of the AI language model.”
