我需要在php上解析json url的幫助

Question

這是json內容：

{
   "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
}

我正在尋找download_link的價值。 我怎樣才能做到這一點？

這是我嘗試的：

<?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

你需要：

- quotes around your JSON
- to remove the quotes around the inner object

$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}' ;

並且您需要從數組訪問權限中刪除[6] ：

$temperatureMin = $jsn['data']['download_link'];

Answer 2

您有一個包含另一個序列化json對象的json對象。

解碼第一個對象，獲取第二個序列化的對象並對其進行解碼：

$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'];
