OpenAI响应文本提取

Question

我正试图修复打开Ai GPT 3 davinci-text-002给我的回复。在控制台中，我得到以下响应文本：

{
  "id": "cmpl-61dshxu43ecbrqir187yilz9mdhsj",
  "object": "text_completion",
  "created": 1665749707,
  "model": "text-davinci-002",
  "choices": [{
    "text": "?\n\nthere is no simple answer to these questions. each person's individual experiences and perspectives will shape their understanding of who they are and what life is. in general, however, people often think of themselves as unique individuals with specific talents, interests, and goals. they may also think of life as a journey full of challenges and opportunities for growth.",
    "index": 0,
    "logprobs": null,
    "finish_reason": "stop"
  }],
  "usage": {
    "prompt_tokens": 7,
    "completion_tokens": 71,
    "total_tokens": 78
  }
}

文本似乎从\n\n开始，以","index"结尾。分离这个文本作为输出的最好方法是什么？以下是我的当前代码：

​

let open_ai_response;

openai_test();

async function openai_test() {
  var prompt_text = "who am i?"
  var prompt_text2 = "what is life"
  var url = "https://api.openai.com/v1/engines/text-davinci-002/completions";

  var xhr = new XMLHttpRequest();
  xhr.open("POST", url);
  xhr.setRequestHeader("Content-Type", "application/json");
  xhr.setRequestHeader("Authorization", "Bearer sk-00x0x0x0x0x0x0x0x0x0x0x0x0x");

  xhr.onreadystatechange = function() {
    if (xhr.readyState === 4) {
      console.log(xhr.status);
      console.log(xhr.responseText);
      var open_ai_response = xhr.responseText;
      console.log(open_ai_response);
      var edit = open_ai_response[0].toUpperCase() + open_ai_response.slice(1).toLowerCase();
      console.log(edit)
    }
  };

  var data = `{
    "prompt": "${prompt_text + prompt_text2}",
    "temperature": 0.7,
    "max_tokens": 256,
    "top_p": 1,
    "frequency_penalty": 0.75,
    "presence_penalty": 0
  }`;

  xhr.send(data);
}

您收到的响应是JSON格式的。您需要在onreadystatechange处理程序中使用JSON.parse(xhr.responseText)解析它，然后可以通过访问choices[0].text属性检索文本。

xhr.onreadystatechange = function() {
  if (xhr.readyState === 4) {
    var response = JSON.parse(xhr.responseText);
    let text = response.choices[0].text
    console.log(text);    
  }
};

注意，这只会从text数组中的第一个元素读取choices。如果您想处理数组中的所有内容，那么您可以修改上面的逻辑来循环它们。
