从Spring Boot向Python flask api发送带有httpPost的POST请求

public class HttpClientExample {
    public static void main(String[] args) {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost("http://your-flask-api-url");

        // 设置请求头
        httpPost.setHeader("Content-Type", "application/json");

        // 设置请求体
        String requestBody = "{\"key1\":\"value1\", \"key2\":\"value2\"}";
        StringEntity entity = new StringEntity(requestBody, "UTF-8");
        httpPost.setEntity(entity);

        try {

            HttpEntity responseEntity = response.getEntity();
            String responseBody = EntityUtils.toString(responseEntity);

            // 处理响应结果
            System.out.println(responseBody);

            response.close();
            httpClient.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
