How to Remove Backslashes from a JSON String

Remove Backslashes from Json Data in JavaScript

Your string is invalid, but assuming it was valid, you'd have to do:

var finalData = str.replace(/\\/g, "");

When you want to replace all the occurences with .replace, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

remove backslash from json string

You can try the following way to achieve what you need,

$jsonString = '\"[\n      {\n        \"id\": \"1\",\n        \"mid\": \"1\",\n        \"num\": \"1\",\n        \"type\": \"wgp\",\n        \"time_changed\": \"time\",\n        \"username\": \"aaa\"\n      }\n    ]\"';

$jsonString = str_replace('\\n', '', $jsonString); // First remove the new line characters in the json string

$jsonString = str_replace('\\', '', $jsonString); // Replace backslash with empty string

echo preg_replace('!\s+!', ' ', $jsonString); // Replace multiple spaces with one

So the output is,

"[ { "id": "1", "mid": "1", "num": "1", "type": "wgp", "time_changed":
"time", "username": "aaa" } ]"

Remove all occurrences of \ from string

Try this:

String jsonFormattedString = jsonStr.replaceAll("\\\\", "");

Because the backslash is the escaping character in a regular expression (replaceAll() receives one as parameter), it has to be escaped, too.

Remove Backslash from JSON string?

I am not very sure your is a function or not. Anyways, the response you receive is having the literal character ' and you need to replace it with ".

Here is the working code:

import urllib2,json
headers = {'User-Agent': 'Mozilla/5.0'}
req = urllib2.Request("http://spatialreference.org/ref/esri/nad-1983-stateplane-california-vi-fips-0406-feet/json/", None, headers)
response = urllib2.urlopen(req)
response_read = response.read()
epsg_json = json.loads(response_read.replace("\'", '"'))
epsg_code = epsg_json['properties']['code']
print(epsg_code)

Hope this helps.

removing the backslashes in json string using the javascript

Actually the problem is not with / slashs. The JSON is INVALID.

remove these " from backend server

{"_body":"{\"timestamp\":\"2016-11-18T04:46:18.972+0000\",\"status\":500,\"error\":\"Internal
Server
Error\",\"exception\":\"java.lang.ArrayIndexOutOfBoundsException\",\"message\":\"1\",\"path\":\"/login\"}","status":500,"ok":false,"statusText":"Internal
Server Error"}

double quote before "{"timestamp and one after login"}"
these two highlighted and your code will work.

var data = '{"_body":{\"timestamp\":\"2016-11-18T04:46:18.972+0000\",\"status\":500,\"error\":\"Internal Server Error\",\"exception\":\"java.lang.ArrayIndexOutOfBoundsException\",\"message\":\"1\",\"path\":\"/login\"},"status":500,"ok":false,"statusText":"Internal Server Error"}';
var json_data = JSON.parse(data);
console.log(json_data);

Remove back slashes from JSON response

You just need to deserialize the body.

let err = {        "_body": "{\"error\":\"264\",\"message\":\"Please enter valid usename/password\",\"object\":null}",        "status": 400,        "ok": false    }
var body = JSON.parse(err._body);console.log(body.message);
