Web API 如何无法反序列化 JSON.Net 反序列化的对象？
这是 Web API 控制器：
public void Put(EditorSubmissionMainView ajaxSubmission) {
// ajaxSubmission: EditorSubmissionMainView with all values ('data' also == null)
string json = "{\"id\":\"row_1377\",\"data\":{\"ROTATION\":\"1\",\"EQUIPMENT\":[{\"id\":\"6\"},{\"id\":\"8\"}],\"NOTES\":\"\"}}";
EditorSubmissionMainView foo = Newtonsoft.Json.JsonConvert.DeserializeObject<EditorSubmissionMainView>(json) as EditorSubmissionMainView;
// foo is a EditorSubmissionMainView but properly deserialized.
}
这是由 Fiddler 捕获并格式化的 JSON：
{
"id": "row_1377",
"data": {
"ROTATION": "1",
"EQUIPMENT": [{
"id": "6"
},
{
"id": "8"
}],
"NOTES": ""
}
}
使用 JSON.Net 但不使用 Web API 控制器序列化的示例类：
[Serializable]
public class EditorSubmissionMainView
{
public string id { get; set; }
public EditorSubmissionMainViewData data { get; set; }
}
[Serializable]
public class EditorSubmissionMainViewData
{
[JsonProperty("ROTATION")]
public int? rotation { get; set; } // Same problem if everything is a string
[JsonProperty("EQUIPMENT")]
public ICollection<Dictionary<string, int?>> equipment { get; set; }
[JsonProperty("NOTES")]
public string notes { get; set; }
}
Web API 使用 JSON.Net，我没有使用任何自定义 JSON 格式化程序——只是将 JSON 传递给 Web API 控制器。为什么这不起作用？
编辑：根据要求，我用这个 Javascript（JQuery DataTables 的一部分）调用我的 Web API 控制器。请注意，我确信相同的 JSON 会到达我的控制器，因为我已经使用 Fiddler 捕获了原始 HTTP 数据包并确保它是正确的：
"ajaxUrl": {
"create": "POST @Url.Content("~/API/MainView")",
"edit": "PUT @Url.Content("~/API/MainView")",
"remove": "DELETE @Url.Content("~/API/MainView")"
},
"ajax": function (method, url, data, successCallback, errorCallback) {
$.ajax({
"type": method,
"url": url,
"data": JSON.stringify(data), // Requires IE8+
"contentType": "application/json",
"dataType": "json",
"success": function (json) {
successCallback(json);
},
"error": function (xhr, error, thrown) {
errorCallback(xhr, error, thrown);
}
});
},
原始 HTTP 请求如下：
