SDK 与集成

Node.js SDK

用 OpenAI Node.js SDK 接入 CokeAPI,服务端调用 chat / images / video 接口。

CokeAPI 与 OpenAI 协议兼容,用 OpenAI 官方 Node.js SDK 即可。

安装

npm install openai
# 或
pnpm add openai
yarn add openai

基础用法

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://cokeapi.com/v1",
  apiKey: process.env.COKEAPI_KEY,
});

// 文本
const resp = await client.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [{ role: "user", content: "用一句话介绍 CokeAPI" }],
});
console.log(resp.choices[0].message.content);

流式

const stream = await client.chat.completions.create({
  model: "grok-4.20-fast",
  messages: [{ role: "user", content: "讲个三句的笑话" }],
  stream: true,
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}

TypeScript 类型

OpenAI SDK 自带完整类型,直接用即可:

import OpenAI, { type ChatCompletionMessageParam } from "openai";

const messages: ChatCompletionMessageParam[] = [
  { role: "system", content: "你是简洁的助手" },
  { role: "user", content: "用一句话介绍 CokeAPI" },
];

const resp = await client.chat.completions.create({
  model: "gpt-4o-mini",
  messages,
});

错误处理

import OpenAI, { RateLimitError, APIError } from "openai";

try {
  await client.chat.completions.create({...});
} catch (err) {
  if (err instanceof RateLimitError) {
    console.log("限流,稍后重试");
  } else if (err instanceof APIError) {
    console.log(`code=${err.error?.code} trace_id=${err.error?.trace_id}`);
  }
}
