  ```

  ```javascript JavaScript theme={null}
  const userIds = ["user1", "user2", "user3"];

  const response = await fetch('http://localhost:5001/user/onlinestatus', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(userIds)
  });

  const data = await response.json();
  console.log(data);
  ```

  ```python Python theme={null}
  import requests

  user_ids = ["user1", "user2", "user3"]

  response = requests.post('http://localhost:5001/user/onlinestatus', json=user_ids)
  data = response.json()
  print(data)
  ```

  ```go Go theme={null}
  package main

  import (
      "bytes"
      "encoding/json"

  func main() {
      userIds := []string{"user1", "user2", "user3"}
      jsonData, _ := json.Marshal(userIds)
      
      resp, err := http.Post(
          "http://localhost:5001/user/onlinestatus",
          "application/json",
          bytes.NewBuffer(jsonData),
      )
      if err != nil {
          panic(err)
      }
      defer resp.Body.Close()
