How do I get the text from an URL in Kotlin

Question

I tried to use this function:

URL("url").readText()

for example with the URL http://date.jsontest.com/ to get a JSON string and manipulate it. However it just doesn't work, it crash.

I mean how to have the text of what is display using kotlin on android ?

Ok I find a way

    val url: URL? = try {
    URL("https://www.instagram.com/p/CNVUZyrDVSQ/?__a=1")
    }catch (e: MalformedURLException){
    Log.d("Exception", e.toString())
    null
    }

and

fun URL.getString(): String? {
    val stream = openStream()
    return try {
        val r = BufferedReader(InputStreamReader(stream))
        val result = StringBuilder()
        var line: String?
        while (r.readLine().also { line = it } != null) {
            result.append(line).appendLine()
        }
        result.toString()
    }catch (e: IOException){
        e.toString()
    }
}

Does this answer your question? [How to parse JSON in Kotlin?](https://stackoverflow.com/questions/41928803/how-to-parse-json-in-kotlin) — Yassin Hajaj, Apr 06 '21 at 22:43
@YassinHajaj I think they're actually asking how to read the file in the first place, not how to parse it. — Henry Twist, Apr 06 '21 at 23:08
@HenryTwist URL readText returns a String so its already there — Yassin Hajaj, Apr 06 '21 at 23:09
Yes I know, I presumed they were having an issue with it as opposed to not knowing how to parse it. But we will see! — Henry Twist, Apr 06 '21 at 23:27
If you're trying to diagnose a crash then you need to [edit] your question and post the stack trace. Trying to guess isn't very efficient. — Henry Twist, Apr 07 '21 at 12:27
@HenryTwist I know it from URL().readtext so I do not need to diagnose it — Riyad Cornu, Apr 07 '21 at 13:30
Well then I'm not sure what your question is for if it's already diagnosed, good luck! — Henry Twist, Apr 07 '21 at 13:45

It's pretty similar:

val htmlString = File("/path/to/sample.html").readText()

it doesn't help me because I want from an url not an file but thanks – Riyad Cornu Apr 07 '21 at 12:08
@RiyadCornu then you should fix the title of the Question. For now it sounds like you want to read a file – Nikolai Shevchenko Apr 07 '21 at 15:00
