我尝试在服务器端解析 json 字符串：

$productInJSON = iconv("UTF-8", "windows-1251", $_POST['productInJSON']);
$data = json_decode($productInJSON,true);
echo "<PRE>";
var_dump($data);

结果：

<PRE>NULL

$productInJSON：

{\"id\":\"17\",\"img\":\"CK0092\",\"title\":\"Серебряное кольцо с гранатом\",\"product\":\"СК0092\",\"size\":\"15,5\",\"size1\":\"\",\"size2\":\"\",\"size3\":\"\",\"size4\":\"\",\"dopInfo\":\"Поверхность изделия обработана нанесением тонкого слоя родия (толщиной 0,1—25 мкм) для повышения отражательной способности, коррозионной стойкости, жаростойкости, обеспечения защитно-декоративных свойств.

您的 JSON 字符串在jsonlint.com验证失败并显示消息

Parse error on line 1:
{    \"id\": \"17\",    
-----^
Expecting 'STRING', '}'

如果不是 JSON，则json_decode()返回 null

如果您stripslashes()先使用它，则可以对其进行解码。

您使用的是什么版本的 PHP？有没有可能你打开了魔术引号？

删除每个 " 之前的斜线并将 ' 添加到字符串的开头和结尾。它应该看起来像这样

$productInJSON='{"id":"17","img":"CK0092","title":"Серебряное кольцо с гранатом"}';

为了能够解决您的问题
