vue3实现流式ai打字效果

正常输出功能。

const completion = await openai.chat.completions.create({
  messages: [
    {role: 'user', content: editorValue}
  ],
  model: 'deepseek-chat', // deepseek-chat对话模型 deepseek-reasoner推理模型
  stream: false, // 流式输出
  max_tokens: 8192, // 限制一次请求中模型生成 completion 的最大 token 数(默认使用 4096)
  temperature: 0.6, // 严谨采样 越低越严谨(默认1)
})

// 返回ai内容
console.log(completion.choices[0].message.content)

流式输出内容。

// 处理流式输出
let content = ''
for await (const chunk of completion) {
  content += chunk.choices[0].delta.content;
  chatState.updateSession(uniKey, content)
  if(chunk.choices[0].finish_reason == 'stop') {
    loading.value = false
  }
  if(props.reachBottom) {
    props.scrollBottom()
  }
}
