调用OpenAi出现连接超时的解决方案_openai sse连接异常data

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;
 
}
