三种方式：
一、访问openai，之前需要国外手机号，现在好像不用验证了，但是调用API还是需要验证手机号
二、购买一个海外服务器，然后自行在海外服务器上部署一套调用OpenAI接口的服务
三、通过一些国内封装好的网站访问，一般收取昂贵会员费
笔者采用的是方案二的改良版，在海外服务器上部署一套桥接服务，然后通过国内服务器进行调用
下面是部分代码：
public void streamCompletions(HttpServletResponse response, List<OpenAIResponsiveAPI.Message> messages, Float temperature) {
OpenAiStreamApi.completionsStream(messages, temperature).blockingForEach(chunk -> {
if (response.containsHeader("Content-Type")) {
response.setHeader("Content-Type", "text/event-stream");
} else {
response.setHeader("Content-Type", "text/event-stream");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Connection", "keep-alive");
}
response.setCharacterEncoding("UTF-8");
response.getWriter().write("data: " + chunk);
response.getWriter().flush();
try {
Thread.sleep(10);
} catch (Exception ex) {
}
});
}
