Python - Parse requests response

The problem is - output is not a valid JSON string and cannot be loaded via json.loads().

I would use regular expressions to locate the output object and then use findall() to locate key-value pairs. Sample working code:

import re


data = """
throw 'allowScriptTagRemoting is false.';
(function() {
    var r = window.dwr._[0];
    //#DWR-INSERT
    //#DWR-REPLY
    r.handleCallback("1", "0", {
        msg: "",
        output: {
            msg: "Showing from city center",
            resultcode: 1,
            scrpresent: true,
            srclatitude: "28.63244546123956",
            srclongitude: "77.21981048583984",
        },
        result: "success"
    });
})();
"""
output_str = re.search(r"output: (\{.*?\}),\n", data, re.DOTALL | re.MULTILINE).group(1)

d = dict(re.findall(r'(\w+): "?(.*?)"?,', output_str))
print(d)

Prints:

{'msg': 'Showing from city center', 'resultcode': '1', 'srclongitude': '77.21981048583984', 'srclatitude': '28.63244546123956', 'scrpresent': 'true'}
