Return JSON 正常方式的字符串

Question

通过一种方法我得到了这样的字符串：

"{\n  \"Name\": \"Next steps for pathway activities\",\n  \"Options\": [\n    {\n      \"Name\": \"Show next steps\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"otoscopy\",\n      \"Group\": \"pathway-activities\"\n    },\n    {\n      \"Name\": \"Treatment cannot continue\",\n      \"ActionType\": \"Navigation\",\n      \"Key\": \"treatment\",\n      \"Group\": \"pathway-activities\"\n    },\n    {\n      \"Name\": \"Refer to GP\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"refer_to_gp\",\n      \"Group\": \"treatment\"\n    },\n    {\n      \"Name\": \"New Wax appointment\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"new_wax_appointment_otoscopy\",\n      \"Group\": \"treatment\"\n    },\n    {\n      \"Name\": \"Continue treatment\",\n      \"ActionType\": \"Navigation\",\n      \"Key\": \"pathway-activities\",\n      \"Group\": \"treatment\"\n    }\n  ]\n}"

如何将其解析为正常格式？ (P.S。结果不一定是字符串，也可以是动态对象)

Answer 1

这样你会得到一个对象

let myStr = "{\n  \"Name\": \"Next steps for pathway activities\",\n  \"Options\": [\n    {\n      \"Name\": \"Show next steps\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"otoscopy\",\n      \"Group\": \"pathway-activities\"\n    },\n    {\n      \"Name\": \"Treatment cannot continue\",\n      \"ActionType\": \"Navigation\",\n      \"Key\": \"treatment\",\n      \"Group\": \"pathway-activities\"\n    },\n    {\n      \"Name\": \"Refer to GP\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"refer_to_gp\",\n      \"Group\": \"treatment\"\n    },\n    {\n      \"Name\": \"New Wax appointment\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"new_wax_appointment_otoscopy\",\n      \"Group\": \"treatment\"\n    },\n    {\n      \"Name\": \"Continue treatment\",\n      \"ActionType\": \"Navigation\",\n      \"Key\": \"pathway-activities\",\n      \"Group\": \"treatment\"\n    }\n  ]\n}";

let myObj = JSON.parse(myStr);

console.log(myObj);

输出将是：

    "Name": "Next steps for pathway activities",
    "Options": [
        {
            "Name": "Show next steps",
            "ActionType": "PathSelector",
            "Key": "otoscopy",
            "Group": "pathway-activities"
        },
        {
            "Name": "Treatment cannot continue",
            "ActionType": "Navigation",
            "Key": "treatment",
            "Group": "pathway-activities"
        },
        {
            "Name": "Refer to GP",
            "ActionType": "PathSelector",
            "Key": "refer_to_gp",
            "Group": "treatment"
        },
        {
            "Name": "New Wax appointment",
            "ActionType": "PathSelector",
            "Key": "new_wax_appointment_otoscopy",
            "Group": "treatment"
        },
        {
            "Name": "Continue treatment",
            "ActionType": "Navigation",
            "Key": "pathway-activities",
            "Group": "treatment"
        }
    ]
}

你可以这样带你 json string

var myStr = "{\n  \"Name\": \"Next steps for pathway activities\",\n  \"Options\": [\n    {\n      \"Name\": \"Show next steps\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"otoscopy\",\n      \"Group\": \"pathway-activities\"\n    },\n    {\n      \"Name\": \"Treatment cannot continue\",\n      \"ActionType\": \"Navigation\",\n      \"Key\": \"treatment\",\n      \"Group\": \"pathway-activities\"\n    },\n    {\n      \"Name\": \"Refer to GP\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"refer_to_gp\",\n      \"Group\": \"treatment\"\n    },\n    {\n      \"Name\": \"New Wax appointment\",\n      \"ActionType\": \"PathSelector\",\n      \"Key\": \"new_wax_appointment_otoscopy\",\n      \"Group\": \"treatment\"\n    },\n    {\n      \"Name\": \"Continue treatment\",\n      \"ActionType\": \"Navigation\",\n      \"Key\": \"pathway-activities\",\n      \"Group\": \"treatment\"\n    }\n  ]\n}";

var _obj = JSON.parse(myStr);

console.log(_obj);

Answer 3

以后如果你想拥有一个对象并对该对象进行操作可以使用Newtonsoft.JsonNuGet包。

只需创建反映您的 json 的类，如下所示：

class MyObject
{
    public string Name { get; set; }
    public IEnumerable<Option> Options { get; set; }

}

class Option
{
    public string Name { get; set; }
    public string ActionType { get; set; }
    public string Key { get; set; }
    public string Group { get; set; }
}

并尝试反序列化这个 json:

var obj = JsonConvert.DeserializeObject<MyObject>(jsonStr);
