Javascript ajax 将动态创建的 json 对象传递给 Web 服务

Question

我有一个具有对象参数的 Web 服务函数，

控制器的功能

public string Post([FromBody]LoanApplication value)
{
LoanApplicationDAO appDAO = new LoanApplicationDAO();
string res = "";
res = appDAO.ReleaseLoanApplication(value);
if (res == null)
{
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.NotFound));
}
return res;
}

LoanApplication包含

public class LoanApplication
{
public string AccountAddress { get; set; }
public string AccountName { get; set; }
public string AccountNumber { get; set; }
public string AccountTag { get; set; }
public string ApplicationNumber { get; set; }
public string ApplicationType { get; set; }
public string Approver { get; set; }
public string BSPTagging { get; set; }
public string BuyOutAmount { get; set; }
public string CIFKey { get; set; }
public string ClassificationEconomicActivity { get; set; }
public string ClassificationSizeOfFirm { get; set; }
public string CoMaker1 { get; set; }
public string CoMaker2 { get; set; }
public string CoMakerName1 { get; set; }
public string CoMakerName2 { get; set; }
public string CreditLimit { get; set; }
public string DateGranted { get; set; }
public string DepEdDivision { get; set; }
public string DepEdEmployeeID { get; set; }
public string DepEdRegion { get; set; }
public string DepEdStation { get; set; }
public string Disbursement { get; set; }
public string DocStamps { get; set; }
public string DOSRIField { get; set; }
public string EmailAddress { get; set; }
public string FirstPaymentDate { get; set; }
public string GroupCode { get; set; }
public string GroupName { get; set; }
public string Insurance { get; set; }
public string InterestRate { get; set; }
public string KnockedOffAccountNumber { get; set; }
public string KnockedOffAmount { get; set; }
public string LandlineNumber { get; set; }
public string LoanAmount { get; set; }
public string LPOCode { get; set; }
public string Maker { get; set; }
public string MaturityDate { get; set; }
public string MobileNumber { get; set; }
public string MonthlyAmort { get; set; }
public string MothersMaidenName { get; set; }
public string NDaysDiscount { get; set; }
public string NoOfInstall { get; set; }
public string PaymentFrequency { get; set; }
public string PayOutMode { get; set; }
public string PEPTagging { get; set; }
public string Product { get; set; }
public string Purpose { get; set; }
public string Security { get; set; }
public string ServiceFees { get; set; }
public string SourceOfPayment { get; set; }
public string SpouseMobileNumber { get; set; }
public string SpouseName { get; set; }
public string Term { get; set; }
public string AOUserID { get; set; }
public string AOName { get; set; }
public string LSOCode { get; set; }
public string IsBranch { get; set; }
}

当我使用 VS 2012 的调试模式时，LoanObj accountname and accountnumer为空，但是当我从 ajax 检查我的传递值时，它有值，从谷歌浏览器控制台检查它

来自 AJAXjsonObj: { AccountName:"test name", AccountAddress: "test address", etc.. }的值的示例格式

我的 Ajax 函数

$('body').on('click', '#btnSubmit', function () {
var jsonObj = {};
$('#lfs_form tbody input[type="text"]').each(function () {
jsonObj[this.id] = this.value;
});
var req2 =
$.ajax({
type: 'post',
url: '../lfsapi/loanapplication/',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
data: JSON.stringify({
jsonObj
//AccountAddress: jsonObj['AccountAddress']
})
});
req.error(function (request, status, error) {
alert(request.responseJSON['Message']);
});
req.done(function (data) {
});
});

但是当我尝试时

data: JSON.stringify({
AccountName: jsonObj['AccountName'],
AccountNumber: jsonObj['AccountNumber']
})

它可以工作，并成功传递预期值以运行，我的示例只有 2 个对象，但在我的实际代码中，我有 40 多个对象，这就是我尝试使用 loop 的原因。有人知道我该如何解决问题吗？

谢谢

附加代码，用于填充我的表单

$.ajax({
type: 'get',
url: '../lfsapi/loanapplication/',
contentType: 'application/json; charset=utf-8',
dataType: 'json'
});
req.error(function (request, status, error) {
alert(request.responseJSON['Message']);
});
req.done(function (data) {
var toappend = '';
$.each(data, function (key, val) {
toappend += '<tr>';
toappend += '<td>' + val + '</td><td><input style="width:500px;" type="text" id=' + val + ' /></td>';
toappend += '</tr>';
});
toappend += '<tr><td align="right" colspan="2"><button id="btnSubmit" type="button">Submit</button></td></tr>';
$('#lfs_form tbody').append(toappend);
});

Answer 1

我注意到你的代码中有几个错误：

• 首先，您使用jsonObj[this.id]为对象赋值 成员。所以this.id应该是帐户名或帐号，否则 不会为所需成员赋值。

• 其次，从 JSON.stringify 中删除额外的制动器 {} 并像这样使用

  JSON.stringify( jsonObj );

Answer 2

通过以下方式解决问题

data: JSON.stringify(jsonObject)

谢谢大家
