PHP接收JSON但无法对其进行解码 [英] PHP Receive JSON but can't decode it

问题描述

我在PHP中收到JSON代码，但是如果我尝试对其进行解码，则不会发生任何事情.

I receive JSON code in PHP but if I try to decode it nothing happens.

代码:

$json = stripslashes($_POST['json']);
$output = json_decode($json);

当我将$json和$output登录到控制台时:

When I log $json and $output to the console:

$json的值为:

{"post":"{'newfavorite':'<div id="1" class="favorite"><sub class="minID">Id 1</sub><a href="http://www.youtube.com/watch?v=1PXQpWm_kq0">http://www.youtu</a><span onclick="movefavorite(1)"><img class="move" title="Move" src="icon/move.png"></span><span onclick="removefavorite(1)"><img class="delete" title="Delete" src="icon/del.png"></span></div>','username':'ifch0o'}"}

$ output的值是:空字符串或null或未定义.我不知道.

$output value is : empty string or null or undefined. I don't know.

控制台说:output is :

推荐答案

您的JSON使用"表示字符串，但是您的内容包含"例如

Your JSON uses " to denote strings however your content contains " e.g.

<div id="1" class="favorite">

因为您已经删除了使用stripslashes()进行转义的字符，所以字符串提早结束了，这将创建无效的JSON.

Because you have removed the character escaping using stripslashes() the strings are ending early and this is creating invalid JSON.

只需删除stripslashes()即可保留这些字符.

Simply remove stripslashes() to keep those characters escaped.

$json = $_POST['json'];
$output = json_decode($json);

这是PHP看到您的JSON的方式:

This is how PHP sees your JSON:

{
   "post": "{'newfavorite':'<div id=",
   1 // Error here - unexpected 1
   " class=" // unexpected string
   ...
}
