How to Send a Date Object as a JSONObject via Parse.com REST API in Java?

Question

How can I send a Date object wrapped in a JSONObject to the Parse.com REST API using Java?

JSONObject jsonObject = new JSONObject();  
Date date = new Date();  
jsonObject.put("dateField", date.getTime());  
// Send jsonObject using your preferred HTTP client.

Answer

To send a Date object as a JSONObject using the Parse.com REST API in Java, you need to convert the Date object into a format that the API can understand. Parse.com generally expects timestamps in milliseconds, which can be obtained from a Date object using `getTime()`. Here’s how you can approach this task.

JSONObject jsonObject = new JSONObject();  
Date date = new Date();  
jsonObject.put("dateField", date.getTime());  
// Send jsonObject using your preferred HTTP client.

Causes

  • The Date object is not in a compatible format for JSON serialization.
  • Not using the correct method to send the JSON data to the Parse API.

Solutions

  • Convert the Date object to milliseconds using `date.getTime()`.
  • Put the timestamp in your JSONObject before sending it to Parse.com.

Common Mistakes

Mistake: Failing to convert Date object to milliseconds properly before sending.

Solution: Ensure you use `date.getTime()` to convert the date.

Mistake: Not handling network exceptions or API response errors.

Solution: Include exception handling to catch potential errors during HTTP requests.
