调用OpenAi出现连接超时的解决方案

在向https://api.openai.com/v1/completions发起http请求之前，使用java.net包下面的Proxy进行代理。

代码如下：

public class OpenAiApi {    public String OpenAiAnswerer(CompletionRequest request, String openAiApiKey) {        //代理        String proxyHost = "代理地址";        int proxyPort = 代理端口;        String url = "https://api.openai.com/v1/completions";        // json为请求体        String json = JSONUtil.toJsonStr(request);        String result = "";        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort));        try {            HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection(proxy);            connection.setRequestProperty("Authorization", "Bearer " + openAiApiKey);            connection.setRequestProperty("Content-Type", "application/json");            connection.setRequestMethod("POST");            connection.setDoOutput(true);            byte[] requestBodyBytes = json.getBytes(StandardCharsets.UTF_8);            try (OutputStream outputStream = connection.getOutputStream()) {                outputStream.write(requestBodyBytes, 0, requestBodyBytes.length);            }            try (InputStream inputStream = connection.getInputStream()) {                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));                StringBuilder response = new StringBuilder();                String line;                while ((line = reader.readLine()) != null) {                    response.append(line);                }                result = response.toString();            }        } catch (IOException e) {            throw new RuntimeException(e);        }        return JSONUtil.toBean(result, CompletionResponse.class);    }}

connection.setRequestProperty("Authorization", "Bearer " + openAiApiKey);
connection.setRequestProperty("Content-Type", "application/json");

我在使用的时候忘记设置了Content-Type，结果一直报错，后面反复观看文档才发现这个必须得设置。

下面是OpenAiAnswerer方法里面形参类CompletionRequest，这里使用了Lombok插件里的@Data注解，自动填入get、set方法和无参构造。（如果添加了有参构造，那么务必加上无参构造）

@Data public class CompletionRequest {    private String model;    private String prompt;    private Integer max_tokens;    private Integer temperature;    private Integer top_p;    private Integer n;    private Boolean stream;    private Integer logprobs;    private String stop;}
