Question

我想使用谷歌地图显示一些GPS坐标。我在ajax查询中使用Web服务。我面临的问题是当我在IIS上部署应用程序时，Web服务不起作用，而在未部署时它可以正常工作。也许我必须先做一些特别的事情，但这很奇怪。这是我的代码：

网络服务

<WebMethod()>
Public Function Test(ByVal idinst As String) As String
    Dim entites As New epgar_formEntities
    Dim jss As New JavaScriptSerializer
    Dim listPatient As New List(Of A5349_DOT_DAILY_REPORT_BY_PROJECT_Result)
    Dim patient As New A5349_DOT_DAILY_REPORT_BY_PROJECT_Result
    listPatient = DalManager.DailyReportByProject(idinst)

    Dim query As New List(Of A5349_DOT_DAILY_REPORT_BY_PROJECT_Result)
    query = From o In listPatient Select o.LATITUDE, o.LONGITUDE, o.AGENT
    Return jss.Serialize(query)
End Function

Ajax查询：

$.ajax({
        type: "POST",
        url: "webservice.asmx/" + webmethod,
        data: JSON.stringify({idinst:'' + project}),  
        dataType: "json",
        contentType: "application/json",
        success: function (data) {
        var rs = JSON.parse(data.d);

         for (var i = 0; i < rs.length; i++) {
          putMarker(rs[i]['LATITUDE'], rs[i]['LONGITUDE'], "Marker Test", "images/marker_rouge.png");
         }
        },
        error: function (jQXHR, textStatus, errorThrown) {
            alert("An error occurred whilst trying to contact the server: " + jQXHR.status + " " + textStatus + " " + errorThrown);
        }
    });

然而，这有效。

<WebMethod()>
Public Function Test(ByVal idinst As String) As String
    Dim entites As New epgar_formEntities
    Dim jss As New JavaScriptSerializer
    Dim listPatient As New List(Of A5349_DOT_DAILY_REPORT_BY_PROJECT_Result)
    patient.LATITUDE = "18.32344"
        patient.LONGITUDE = "-72.79875"
        patient.AGENT = "user"

        patient1.LATITUDE = "18.32344"
        patient1.LONGITUDE = "-72.79875"
        patient1.AGENT = "user"

        patient2.LATITUDE = "18.32344"
        patient2.LONGITUDE = "-72.79875"
        patient2.AGENT = "user"

        listPatient.add(patient)
        listPatient.add(patient1)
        listPatient.add(patient2)
    query = From o In listPatient Select o.LATITUDE, o.LONGITUDE, o.AGENT
    Return jss.Serialize(query)
End Function

如果您有任何想法，请非常欢迎您。
