日志含义传递JSON对象失败

Failed to pass JSON Object

本文关键字：JSON 对象 失败 日志      更新时间：2023-09-26

我试图调用服务器端方法并使用$.ajax()传递Json格式的值，但我得到了这个错误:

{"Message":"Invalid web service call, missing value for parameter:   'u0027obj'u0027.","StackTrace":"   at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)'r'n   at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)'r'n   at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)'r'n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

当我硬编码值&尝试发送，然后是正确的..但无法传递Json对象。

客户端代码

<script type="text/javascript">
function DailyReportFn() {
    debugger;
    var RadTabStrip1 = $find("<%= RadTabStrip1.ClientID %>");
    var tab = RadTabStrip1.findTabByText("Qualified Families");
    var RadPageView1 = tab.get_pageView()
    var elment = RadPageView1.get_element();

    var DailyReport = {
        NewReg: $find("<%= NewReg.ClientID %>").get_textBoxValue(),
        Removed: $find('<%= Removed.ClientID %>').get_textBoxValue(),
        Homevt: $find('<%= Homev.ClientID %>').get_textBoxValue()
    }

    $.ajax({
        type: "POST",
        url: '<%=ResolveUrl("~/DModules/Hc/WebMethods.aspx/DemoReport")%>',
        data: JSON.stringify(DailyReport),
        contentType: "application/json",
        dataType: "json",
        async: false,
        cache: false,
        success: function (data) {
            debugger;
            alert(data);
        },
        error: function (x, e) {
            alert(x.responseText);
        },
    });
}

服务器端代码

[WebMethod, ScriptMethod] 
public static int DemoReport(Drep report)
{
    int result = -1;
    int NewReg = report.NewReg;
    int Removed = report.Removed;
    int Homev = report.Homevt;
    return result;
}

试试这个

data: JSON.stringify({report:DailyReport}),

在发布之前，尝试先检查JSON.stringify(DailyReport)的值。

var DailyReport = {
    NewReg: $find("<%= NewReg.ClientID %>").get_textBoxValue(),
    Removed: $find('<%= Removed.ClientID %>').get_textBoxValue(),
    Homevt: $find('<%= Homev.ClientID %>').get_textBoxValue()
}
console.info(JSON.stringify(DailyReport));//OR: alert(JSON.stringify(DailyReport));
$.ajax({...
