Python-解析請求響應

Question

我有一個發布數據的端點。

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

我在Javascript中收到以下響應：-

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"
    });
})();

如何解析響應？ 我基本上想要output json。 我怎么能得到相同的？

問題是- output不是有效的JSON字符串，無法通過json.loads()加載。

我將使用正則表達式來定位output對象，然后使用findall()來定位鍵值對。 示例工作代碼：

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'}
