请求Openai接口 java版+python版 （代理方式）

以下是请求OPENAI接口的java版本和python，增加请求超时重试3次的逻辑；

        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("your_proxy_host", your_proxy_port));

        httpClient = builder.build();

    }

        executorService.submit(() -> {
            int retries = 0;
            boolean success = false;

            while (retries < RETRY_COUNT && !success) {
                try {
                    Request request = new Request.Builder()
                            .url(OPENAI_API_URL)
                            .header("Authorization", "Bearer " + API_KEY)

                        @Override
                        public void onFailure(Call call, IOException e) {
                            System.out.println("请求失败: " + e.getMessage());
                        }

                        @Override
                        public void onResponse(Call call, Response response) throws IOException {
                            if (response.isSuccessful()) {
                                System.out.println("请求成功: " + response.body().string());
                                success = true;
                            } else {
                                System.out.println("请求失败: " + response.message());
                            }
                        }
                    });

                    success = true;
                } catch (Exception e) {
                    retries++;
                    System.out.println("重试次数: " + retries);
                }
            }
        });
    }

    public static void main(String[] args) {
        OpenAIRequest openAIRequest = new OpenAIRequest();
        openAIRequest.requestOpenAI();
    }
}

注意，需要替换`OPENAI_API_URL`、`API_KEY`、`your_proxy_host`和`your_proxy_port`为您的实际值。同时，需要添加OkHttp库作为依赖项。

        self.max_workers = max_workers
        self.session = self._create_session()

    def _create_session(self):
        session = requests.Session()
        if self.proxy:
            session.proxies.update(self.proxy)

        retries = Retry(total=3, backoff_factor=1, status_forcelist=[429, 500, 502, 503, 504])
        adapter = HTTPAdapter(max_retries=retries)
        session.mount('http://', adapter)

        return session

            'Authorization': f'Bearer {self.api_key}',
            'Content-Type': 'application/json'
        }
        try:
            response = self.session.post(url, json=data, headers=headers, timeout=10)
            response.raise_for_status()
            return response.json()
        except requests.exceptions.RequestException as e:
            print(f"请求失败: {e}")
            return None

    def request(self, urls, data_list):
        with ThreadPoolExecutor(max_workers=self.max_workers) as executor:
            futures = [executor.submit(self._request_openai, url, data) for url, data in zip(urls, data_list)]

            results = []
            for future in as_completed(futures):
                result = future.result()
                if result:
                    results.append(result)

        return results

# 使用示例
if __name__ == "__main__":
    api_key = "your_openai_api_key"
    proxy = {
        "http": "http://proxy.example.com:8080",
        "https": "https://proxy.example.com:8080"
    }
    requester = OpenAIRequester(api_key, proxy)

    urls = ["https://api.openai.com/v1/engines/davinci-codex/completions"] * 3
    data_list = [
        {
            "prompt": "Python code to calculate the factorial of a number",
            "max_tokens": 100,
            "n": 1,
            "stop": None,
            "temperature": 0.5,
        }
    ] * 3

    results = requester.request(urls, data_list)
    print(results)

将`your_openai_api_key`替换为您的OpenAI API密钥，并根据需要设置代理。这个类将使用线程池并发地请求OpenAI接口，并在遇到超时或其他错误时自动重试3次
