How to Create InputStream Object from JsonObject
file, inputstream, java, json, rest
Solution
You can convert a `JSONObject` into its `String` representation, and then convert that String into an `InputStream`.
The code in the question has a JSONObject being cast into `File`, but I am not sure if that works as intended. The following, however, is something I have done before (currently reproduced from memory):
String str = json.getJSONObject("data").toString();
InputStream is = new ByteArrayInputStream(str.getBytes());
Note that the `toString()` method for `JSONObject` overrides the one in `java.lang.Object` class.
From the Javadoc:
Returns: a printable, displayable, portable, transmittable representation of the object, beginning with { (left brace) and ending with } (right brace).
Problem
I'm trying to figure out how one goes about retrieving the raw bytes stored in a JsonObject and turns that into an InputStream object? I figured it might be something like: ``` InputStream fis = new FileInputStream((File)json.getJsonObject("data")); ``` Granted I haven't tried that out, but just wanted to know if anyone had any experience with this and knew the preferred way to do it?
