我有一個強類型的Razor視圖,它顯示了一個類的記錄。該視圖顯示用戶可用來更新記錄的表單(下拉菜單,幾個複選框和幾個文本框)。當用戶通過更改控件的值來修改字段時,會立即將ajax調用發送到Web API以更新該字段。下面的Ajax調用工作正常:Web API的序列化表單數據API請求MVC 5
$(document).ready(function() {
$(this).on("change", function (e) {
var editRecordURL = $("#editRecordURL").val();
var key = $("#AccessVM_Id").val();
var mode = $("#AccessVM_AccessMode").val();
var failLim = $("#AccessVM_LoginFailLimit").val();
var cap = $("#AccessVM_PwdWCap").is(':checked');
...
var rec = {
Id: key,
AccessMode: mode,
LoginFailLimit: failLim,
PwdWCap: cap,
....
};
$.ajax({
type: "PUT",
url: editRecordURL,
data: JSON.stringify(rec),
contentType: 'application/json; charset=utf-8',
success: function (msg) {
bootbox.alert("Success: Record updated successfully!");
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
bootbox.alert("Error: " + errorThrown);
}
});
});
});
不過,我想使這一功能更通用的,因此它可再用於其他形式(尤其是那些擁有更多的數據來更新)。理想情況下,拍攝對象將被填充這樣的:
var rec = $("#form").serializeArray();
不幸的是,這並不因爲應用JSON.stringify()
上rec
它不會返回預期的JSON字符串後的工作。相反,它發出這樣一個系列的名稱/值對:
[{"name":"__RequestVerificationToken","value":"qVedWHJ6HIrqtLJpTxp4m5D2ehZ_AdjCOvQtz4Jyzlg0cdocsWqcTCiE2jzIEB7UsJPwuSZeZF7y1GsluHNrNCDV1wrHjU1UJO5vMMGTLB41"},{"name":"AccessVM.Id","value":"1"},{"name":"AccessVM.AccessMode","value":"1"},{"name":"AccessVM.LoginFailLimit","value":"10"},{"name":"AccessVM.PwdWCap","value":"true"},{"name":"AccessVM.PwdWCap","value":"false"},{"name":"AccessVM.PwdWNum","value":"true"},{"name":"AccessVM.PwdWNum","value":"false"},{"name":"AccessVM.PwdWSC","value":"true"},{"name":"AccessVM.PwdWSC","value":"false"},{"name":"AccessVM.PwdMinLen","value":"6"},{"name":"AccessVM.PwdMaxLen","value":"25"},{"name":"AccessVM.PwdChange","value":"90"},{"name":"AccessVM.PwdPrevUsedLimit","value":"10"}]
那麼,如何解決這個問題因此字符串的樣子:
[{"AccessVM.Id": 1, "AccessVM.AccessMode": 1, "AccessVM.LoginFailLimit": 10, "AccessVM.PwdWCap": true, "AccessVM.PwdWNum": true, "AccessVM.PwdWSC": false, "AccessVM.PwdMinLen": 6, "AccessVM.PwdMaxLen": 25, "AccessVM.PwdChange": 90, "AccessVM.PwdPrevUsedLimit": 10}]
的Web API控制器:
public class PoliciesController : ApiController
{
....
// PUT: api/policies/1
[ResponseType(typeof(void))]
public IHttpActionResult PutPolicy(int id, AccessItemViewModel polDto)
{
....
}
....
}
查看車型
public class PolicyViewModel
{
public AccessItemViewModel AccessVM { get; set; }
....
}
public class AccessItemViewModel
{
public int Id { get; set; }
public int AccessMode { get; set; }
public int LoginFailLimit { get; set; }
public bool PwdWCap { get; set; }
....
}
Razor視圖:
@model App.Web.ViewModels.PolicyViewModel
....
@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary("", new { @class = "text-danger" })
<input type="hidden" id="editRecordURL" value="@Model.ExtraVM.EditRecordUrl" />
@Html.LabelFor(m => m.AccessVM.AccessMode, new { @class = "col-xs-5" })
@Html.HiddenFor(m => m.AccessVM.Id)
@Html.DropDownListFor(m => m.AccessVM.AccessMode, new SelectList(Model.AccessModes, "Mode", "Description"), null, new { @class = "input-sm col-xs-7" })
@Html.LabelFor(m => m.AccessVM.LoginFailLimit, new { @class = "col-xs-9" })
@Html.DropDownListFor(m => m.AccessVM.LoginFailLimit, new SelectList(Model.LoginLimits, "LoginFailLimit", "Value"), null, new { @class = "input-sm col-xs-3" })
@Html.LabelFor(m => m.AccessVM.PwdWCap, new { @class = "col-xs-11" })
@Html.CheckBoxFor(m => m.AccessVM.PwdWCap, new { @class = "input-xs col-xs-1" })
....
}
這是'$( 「#形式」)。序列化()'(不' .serializeArray()')並移除'contentType:'application/json; charset = utf-8','不要stringify(只使用'data:$(「#form」)。serialize(),') –
這不起作用(我得到錯誤「未找到」),因爲它創建一個查詢字符串的鍵值如下:AccessVM.Id = 1&AccessVM.AccessMode = 1&AccessVM.LoginFailLimit = 1&AccessVM.PwdWCap = false&AccessVM.PwdWNum = false&AccessVM.PwdWSC = false&AccessVM。PwdMinLen = 3 ... Web API端點需要發送一個類型爲「policy」的對象(這意味着一個JSON對象)。但是如果我能以某種方式把這個字符串變成一個JSON對象,那將是非常棒的! –
你是什麼'政策'模型。如果它包含一個名爲'AccessVM'的複雜屬性,它包含'Id','AccessMode'等屬性,它會很好地綁定。並顯示部分視圖和控制器(根據您說的正確的話,那麼POST方法中的模型與視圖中的模型不同(它應該是這樣) –
