我需要帮助解析php上的json url

Question

Here is the json content:

{
   "success":true,
    "data":"{\"campaign_name\":\"helloworld\",\"download_link\":\"https:\\\/\\\/google.com\\\/accesskey\\\/getfile\\\/m-spqn-e61-2aef2575a0b5250354f2b0fda033e703?token=HUSYjdC5jyJskXUHiKn13l1A1BaAjH2R&dcma=5ecceb0522bcd0db\",\"link\":\"http:\\\/\\\/www.lol.com\\\/remove\\\/remove.php\"}",
    "message":null
}

I'm looking to get the value of download_link. How can I do that?

This is what I tried:

<?php
$jsndata = {"success":true,"data":"{\"campaign_name\":\"helloworld\",\"download_link\":\"https:\\\/\\\/google.com\\\/accesskey\\\/getfile\\\/m-spqn-e61-2aef2575a0b5250354f2b0fda033e703?token=HUSYjdC5jyJskXUHiKn13l1A1BaAjH2R&dcma=5ecceb0522bcd0db\",\"link\":\"http:\\\/\\\/www.lol.com\\\/remove\\\/remove.php\"}","message":null};
$jsn = json_decode($jsndata,true);

$temperatureMin = $jsn['data'][6]['download_link'];
echo $temperatureMin;
 ?>

Answer 1

You have a json object containing another serialized json object.

Decode the first object, get the second serialized object and decode that:

$jsndata = '{
    "success":true,
    "data":"{\"campaign_name\":\"helloworld\",\"download_link\":\"https:\\\/\\\/google.com\\\/accesskey\\\/getfile\\\/m-spqn-e61-2aef2575a0b5250354f2b0fda033e703?token=HUSYjdC5jyJskXUHiKn13l1A1BaAjH2R&dcma=5ecceb0522bcd0db\",\"link\":\"http:\\\/\\\/www.lol.com\\\/remove\\\/remove.php\"}",
    "message":null
}';

// Decode the main json object
$jsn = json_decode($jsndata,true);

// Since 'data' is another serialized object, you need to decode that as well:
$data = json_decode($jsn['data'], true);

// Now you can access the contents of 'data'
echo $data['download_link'];
