Question

我已经阅读了其他一些问题，但仍无法找到我的具体问题的答案。我试图用Ajax Post调用vb.net sub。 ajax函数正在取得成功，但从未在我的sub中遇到断点或实际插入到我的数据库中。任何帮助表示赞赏。

aspx.vb

<System.Web.Services.WebMethod()> _
Public Shared Sub insertKPI(id As String)
    Dim constr As String = ConfigurationManager.ConnectionStrings("SqlServerConnectionString").ConnectionString
    Using con As New SqlConnection(constr)
        Using cmd As New SqlCommand
            cmd.CommandText = "kpi_InsertKPI"
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.AddWithValue("PartnerLinkCode", HttpContext.Current.Session.Contents("partnerlinkcode").ToString)
            cmd.Parameters.AddWithValue("UserLinkCode", HttpContext.Current.Session.Contents("userlinkcode").ToString)
            cmd.Parameters.AddWithValue("KPIInfoLinkCode", id)
            cmd.Connection = con
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
        End Using
    End Using
End Sub

脚本

function addWidget(id){
    $.ajax({
        type: "POST",
        url: "../secure/scorecardtable.aspx/insertKPI",
        data: '{"id":' + JSON.stringify(id) + '}',
        datatype: "json",
        success: function(result){
            alert("New kpi should be in database");
            console.log(result);
        },
        error: function(xhr, textStatus, errorThrown){
            alert("There was an error inserting the kpi into the database.  " + xhr.status + ': ' + errorThrown);
        }
    }); // End Ajax
}

将contentType添加到我的ajax函数实际上使它工作。

function addWidget(id){
    $.ajax({
        type: "POST",
        url: "../secure/scorecardtable.aspx/insertKPI",
        data: '{"id":' + JSON.stringify(id) + '}',
        contentType: "application/json; charset=utf-8",
        datatype: "json",
        success: function(result){
            alert("New kpi should be in database");
            console.log(result);
        },
        error: function(xhr, textStatus, errorThrown){
            alert("There was an error inserting the kpi into the database.  " + xhr.status + ': ' + errorThrown);
        }
    }); // End Ajax
}

Ajax Post击中成功但没有击中VB.Net功能
