从Android应用程序接收服务器上的POST请求(Spring Framework)

URL url = new URL("https://your-server.com/api/endpoint");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);

OutputStream outputStream = connection.getOutputStream();
outputStream.write(data.getBytes("UTF-8"));
outputStream.close();

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    InputStream inputStream = connection.getInputStream();
    // 处理服务器返回的响应
}

@RestController
@RequestMapping("/api")
public class MyController {

    @PostMapping("/endpoint")
    public ResponseEntity<String> handlePostRequest(@RequestBody String requestBody) {
        // 处理请求体中的数据
        String response = "Hello from server!";
        return new ResponseEntity<>(response, HttpStatus.OK);
    }
}

@SpringBootApplication
public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}
