如何将包含编码 HTML 的 json 字符串反序列化为 JObject？

Question

我有一个包含编码 HTML 的 json 字符串，如下所示，这是我在执行 Shopify Liquid 转义后得到的。我正在尝试解码内部 HTML 并将此字符串反序列化为 JObject。

{
    "testId": 494254,
    "languageIdentifier": "en_us",
    "overview":"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Overview&#39;ff&#39; Test&lt;/span&gt;&lt;/p&gt;",  
    "responsibilities":"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Responsibilities&lt;/span&gt;&lt;/p&gt;",
    "qualifications":"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Qualifications&lt;/span&gt;&lt;/p&gt;",
    "guidance":"z_used_Guidance Test",
    "additionalDetailsForInternalCandidates":"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Additional Details&lt;/span&gt;&lt;/p&gt;",
    "requisitionNotes":"Requisition Notes"
}

实际html是：

{
    "testId": 494254,
    "languageIdentifier": "en_us",
    "overview": "<p style=\"margin: 0px;\"><span>Overview'ff' Test</span></p>"
    "responsibilities": "<p style=\"margin: 0px;\"><span>Responsibilities</span></p>"
    "qualifications": "<p style=\"margin: 0px;\"><span>Qualifications</span></p>"
    "additionalDetailsForInternalCandidates":"<p style=\"margin: 0px;\"><span>Additional Details</span></p>",
    "guidance":"z_used_Guidance Test",
    "requisitionNotes":"Requisition Notes"
}

但是，当我尝试解码和反序列化时，它失败了。我的代码是：

string test = "{\r\n\t\"testId\": 494254,\r\n\t\"languageIdentifier\": \"en_us\",\r\n\t\"overview\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Overview&#39;ff&#39; Test&lt;/span&gt;&lt;/p&gt;\",\t\r\n\t\"responsibilities\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Responsibilities&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"qualifications\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Qualifications&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"guidance\":\"z_used_Guidance Test\",\r\n\t\"additionalDetailsForInternalCandidates\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Additional Details&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"requisitionNotes\":\"Requisition Notes\"}";
var jsonString = HttpUtility.HtmlDecode(test);
var objectjson = JsonConvert.DeserializeObject<JObject>(jsonString);

但是，我得到这个错误：

'After parsing a value an unexpected character was encountered: m. Path 'overview', line 4, position 23.'

谁能帮我解码编码的 HTML 并将其反序列化为 JObject？我希望它像原始输入

一样作为解码后的 html 字符串

{
    "testId": 494254,
    "languageIdentifier": "en_us",
    "overview": "<p style=\"margin: 0px;\"><span>Overview'ff' Test</span></p>",
    "responsibilities": "<p style=\"margin: 0px;\"><span>Responsibilities</span></p>",
    "qualifications": "<p style=\"margin: 0px;\"><span>Qualifications</span></p>",
    "additionalDetailsForInternalCandidates":"<p style=\"margin: 0px;\"><span>Additional Details</span></p>",
    "guidance":"z_used_Guidance Test",
    "requisitionNotes":"Requisition Notes"
}

提前致谢。

您必须按照以下 C# 代码执行操作

图书馆

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

代码

string test = "{\r\n\t\"testId\": 494254,\r\n\t\"languageIdentifier\": \"en_us\",\r\n\t\"overview\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Overview Test&lt;/span&gt;&lt;/p&gt;\",\t\r\n\t\"responsibilities\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Responsibilities&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"qualifications\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Qualifications&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"guidance\":\"z_used_Guidance Test\",\r\n\t\"additionalDetailsForInternalCandidates\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Additional Details&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"requisitionNotes\":\"Requisition Notes\"}";

JToken objectData = JToken.Parse(test);
var testId = objectData["testId"];
var languageIdentifier = objectData["languageIdentifier"];

如果您想从 html 而不是 c# 执行此操作，请按照以下操作。

<!DOCTYPE html>
<html>
<body>
<h2>Create Object from JSON String</h2>
<p id="demo"></p>

<script>
var txt = "{\r\n\t\"testId\": 494254,\r\n\t\"languageIdentifier\": \"en_us\",\r\n\t\"overview\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Overview Test&lt;/span&gt;&lt;/p&gt;\",\t\r\n\t\"responsibilities\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Responsibilities&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"qualifications\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Qualifications&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"guidance\":\"z_used_Guidance Test\",\r\n\t\"additionalDetailsForInternalCandidates\":\"&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Additional Details&lt;/span&gt;&lt;/p&gt;\",\r\n\t\"requisitionNotes\":\"Requisition Notes\"}"
var obj = JSON.parse(txt);
document.getElementById("demo").innerHTML = "TestID : " + obj.testId + " and languageIdentifier : " + obj.languageIdentifier;
</script>
</body>
</html>

您假设您有一个HTML编码的JSON文件。事实并非如此。您拥有的是 一个包含 HTML 编码值 的 JSON 文件。那是不一样的。

意味着你先需要解析JSON然后然后HTML-解码值.

string jsonString = @"{
    ""testId"": 494254,
    ""languageIdentifier"": ""en_us"",
    ""overview"":""&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Overview&#39;ff&#39; Test&lt;/span&gt;&lt;/p&gt;"",  
    ""responsibilities"":""&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Responsibilities&lt;/span&gt;&lt;/p&gt;"",
    ""qualifications"":""&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Qualifications&lt;/span&gt;&lt;/p&gt;"",
    ""guidance"":""z_used_Guidance Test"",
    ""additionalDetailsForInternalCandidates"":""&lt;p style=&quot;margin: 0px;&quot;&gt;&lt;span&gt;Additional Details&lt;/span&gt;&lt;/p&gt;"",
    ""requisitionNotes"":""Requisition Notes""
}";

var objectjson = JsonConvert.DeserializeObject<JObject>(jsonString);
var htmlEncodedValue = objectjson.Value<string>("overview");
var decodedValue = HttpUtility.HtmlDecode(htmlEncodedValue);
