Question

In my Javascript app I make an API call to my Django server's /rest-auth/registration code. If the registration attempt fails the API call returns the following JOSN which I am having problems parsing:

{
    "_body":"{\"email\":[\"Enter a valid email address.\"],\"username\":[\"A user with that username already exists.\"]}",
    "status":400,
    "ok":false,
    "statusText":"Bad Request",
    "headers":{
        "Server":[
            "Apache/2.4.23 (Amazon) mod_wsgi/3.5 Python/3.4.3"
        ],
        "Transfer-Encoding":[
            "Identity"
        ],
        "Content-Type":[
            "application/json"
        ],
        "Date":[
            "Thu",
            " 20 Oct 2016 13:10:04 GMT"
        ],
        "Connection":[
            "close"
        ],
        "X-Frame-Options":[
            "SAMEORIGIN"
        ],
        "Access-Control-Allow-Origin":[
            "*"
        ],
        "Allow":[
            "POST",
            " OPTIONS"
        ]
    },
    "type":2,
    "url":"http://www.worldimagearchive.com/rest-auth/registration/"
}

I can see how to pull out the 'status' and 'ok' values (using err.status & err.ok) but can't work out how to parse the "_body" section which may or may not contain errors for email, username, etc.

What do I need to do to get the value of the \"email\" section (and test if that section exists by the way) ?

它是JSON中的JSON。我尝试了很多东西，没有任何效果，所以这是一种非传统的方法来抓取电子邮件。

err=err.replace('"{','{').replace('}"','}'). replace(/\\/gi, '')
JSON.parse(input)._body.email;//"Enter a valid email address."
