json_decode()不适用于此有效JSON字符串

Question

这是我的应用程序从Postmark收到的JSON字符串,一个入站电子邮件递送服务:

将其复制到任何JSON验证器中,您将看到它是有效的.

但是,当我json_decode();在PHP中运行此字符串时,它会无声地失败.运行echo json_last_error();返回的错误代码时是4.这对应于语法错误.

只需找到,更换\到\\在我的代码编辑器,我能得到这个工作,但我怎样才能让PHP自动做到这一点？

编辑:正如在评论中发现,从文件中读取的时候,因为PHP不会尝试解析任何反斜线我上面张贴的确切字符串正常工作等.然而,在阅读时从似乎是解析斜线file_get_contents('php://input)这是什么现在给我带来了麻烦.

你可以在变量上执行此操作:

$json = str_replace('\\', '\\\\', $json);
