javascript - Python-解析请求响应

Question

我有一个发布数据的端点。

r = requests.post(url, data=data, headers=headers)

我在 Javascript 中得到以下响应:-

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"
    });
})();

如何解析响应？我基本上想要 output json。我怎样才能得到同样的东西？

问题是 - output 不是有效的 JSON 字符串，无法通过 json.loads() 加载。

我将使用正则表达式来定位 output 对象，然后使用 findall() 来定位键值对。示例工作代码:

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)

打印:

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