Go / Java / PHP / C#

以下示例只使用各语言的标准库发送 HTTP 请求，不依赖第三方 SDK。各语言社区的 OpenAI SDK 同样可用，只需把 Base URL 设置为 https://vip.zen-ai.top/v1。

package main

import (
	"bytes"

	req, _ := http.NewRequest("POST", "https://vip.zen-ai.top/v1/chat/completions", bytes.NewReader(body))
	req.Header.Set("Authorization", "Bearer "+os.Getenv("VIP_API_KEY"))
	req.Header.Set("Content-Type", "application/json")

	resp, err := http.DefaultClient.Do(req)

	if err := json.Unmarshal(data, &result); err != nil || len(result.Choices) == 0 {
		fmt.Println(resp.Status, string(data))
		return
	}
	fmt.Println(result.Choices[0].Message.Content)
}

流式输出要点

所有语言处理流式响应的方式相同：

请求体加上 "stream": true。
逐行读取响应体，只处理以 data: 开头的行。
遇到 data: [DONE] 结束；其余每行去掉前缀后是一个 JSON，增量文本位于 choices[0].delta.content。
读取超时要设置得足够长，或按行读取时不设置总超时。
