【问题描述】：

从 Mandrill 收到的 JSON 字符串：

["event":"hard_bounce","_id":"5760ab383b1b4e358f10cfe759440dce","msg":"ts":1426810207,"_id":"5760ab383b1b4e358f10cfe759440dce","state":"bounced","subject ":"鸡尾酒会","email":"[e-mail]","tags":[],"smtp_events":[],"resends":[],"_version":"Nes5DEa8tOq5Z6m_b9AWIA", "diag":"smtp;501 5.1.3 邮箱地址"[e-mail]"（不可打印字符）中的语法错误","bgtools_code":10,"sender": "[e-mail]","template":null,"bounce_description":"bad_mailbox","ts":1426822720]

更新：

这是从 mandrill 收到的另一个无效字符串

["event":"hard_bounce","_id":"cddb25d2023a486a89454d5c6cefc4c9","msg":"ts":1427904051,"_id":"cddb25d2023a486a89454d5c6cefc4c9","state":"bounced","subject ":"周年鸡尾酒会","email":"[e-mail]","tags":[],"smtp_events":[],"resends":[],"_version":"CvawLhm-1KO4OY_FsZ3uSA" ,"diag":"smtp;550 No such User Here"","bgtools_code":10,"sender":"[e-mail]","template":null," bounce_description":"bad_mailbox","ts":1427935354]

预期的 JSON 字符串：

[
    
        "event": "hard_bounce",
        "_id": "5760ab383b1b4e358f10cfe759440dce",
        "msg": 
            "ts": 1426810207,
            "_id": "5760ab383b1b4e358f10cfe759440dce",
            "state": "bounced",
            "subject": "Cocktail Party",
            "email": "[e-mail]",
            "tags": [],
            "smtp_events": [],
            "resends": [],
            "_version": "Nes5DEa8tOq5Z6m_b9AWIA",
            "diag": "smtp;501 5.1.3 Syntax error in mailbox address '[e-mail]' (non-printable character)",
            "bgtools_code": 10,
            "sender": "[e-mail]",
            "template": null,
            "bounce_description": "bad_mailbox"
        ,
        "ts": 1426822720
    
]

验证 JSON 字符串 PHP 代码：

function validateMandrillJSONString($JSONString)
    $JSONString = json_decode($JSONString);
    if(is_array($JSONString))
        if(empty($JSONString))
            return FALSE;
        
        else
            return TRUE;
        
    
    else
        return FALSE;
    

问题： 当我将 Received JSON 字符串发送到上述 php 函数时，它返回 FALSE。然后我发现JSON String With Double Quotes("diag":"smtp;501 5.1.3 Syntax error in mailbox address "[e-mail]" (non-printable character)" ）。

不仅仅是上面的字符串。我还有几个类似的字符串。例如，当用户在主题中给出双引号时，例如 (Hi "Madhu", How are you?) 我得到了同样的错误。

这是山魈的错误还是我这边的错误。如果是我这边，我该如何解决？

提前致谢。

【问题讨论】：

听起来像是 mandril 的错误。你自己对数组进行 json_encode 吗？或者曼德里尔会这样做吗？如果您从 mandril 收到此响应，那么这是他们系统上的错误。

@Jordy - 我从 mandrill 收到了这个字符串。我没有使用json_encode。

你能提供http请求和响应山魈吗？我同意@jordy，但在你写问题来支持之前，你应该确保它真的是 Mandrill 错误。

谢谢@Sergey Chizhik。我很确定它来自山魈。我已经发布了从山魈收到的回复。我的 Bounce webhook 正在发生这种情况。

【参考方案1】：

我可以这么说，这个 bug 来自 mandrill it self。我从山魈那里得到无效的 JSON。 “diag”键值内的双引号的主要问题。

这是我使用字符串替换的临时修复。

//Data received from mandrill
$queueData = '["event":"hard_bounce","_id":"5760ab383b1b4e358f10cfe759440dce","msg":"ts":1426810207,"_id":"5760ab383b1b4e358f10cfe759440dce","state":"bounced","subject":"Cocktail Party","email":"[e-mail]","tags":[],"smtp_events":[],"resends":[],"_version":"Nes5DEa8tOq5Z6m_b9AWIA","diag":"smtp;501 5.1.3 Syntax error in mailbox address "[e-mail]" (non-printable character)","bgtools_code":10,"sender":"[e-mail]","template":null,"bounce_description":"bad_mailbox","ts":1426822720]';

$queueData = str_replace(':""',':"""',$queueData); // Temp Fix
$queueData = str_replace('""','"',$queueData); // Temp Fix

欢迎提出建议

谢谢。
