javascript - Parse a JSON body after multipart ajax Angular call

Question

I'm trying to parse a body that is coming to me after an api call using ajax angularJs. After call the response is:

--3531b7e68196e3144197f82db0864b7e391c8b0ad51c4176c28f8ac41b3c
Content-Disposition: form-data; name="passport"; filename="passport.json"
Content-Type: application/json

{
    "name": "Nothing",
    "dob_display": "10/11/1997",
    "dob_accuracy": "FD",
    "owner_firstname": "Nothing",
    "owner_surname": "To Understand"
}
--3531b7e68196e3144197f82db0864b7e391c8b0ad51c4176c28f8ac41b3c--

I didn't find a plugin to get the body from this request. Do I need to make manual parser or I could get another solution. Can someone help me?

You can use String.prototype.slice() with String.prototype.indexOf() at each parameter to get indexes of "{", "}", JSON.parse().

let response = `--3531b7e68196e3144197f82db0864b7e391c8b0ad51c4176c28f8ac41b3c
Content-Disposition: form-data; name="passport"; filename="passport.json"
Content-Type: application/json

{
    "name": "Nothing",
    "dob_display": "10/11/1997",
    "dob_accuracy": "FD",
    "owner_firstname": "Nothing",
    "owner_surname": "To Understand"
}
--3531b7e68196e3144197f82db0864b7e391c8b0ad51c4176c28f8ac41b3c--`;

let json = JSON.parse(response.slice(response.indexOf("{")
           , response.indexOf("}") + 1));

let {name} = json;

console.log(json);
console.log({name});
console.log(name);
