让WebService只返回纯文本JSON

本文关键字：文本 JSON 返回 WebService | 更新日期: 2023-09-27 18:01:48

我正在尝试使用web服务返回FullCallendar资源请求的json资源列表:

下面是web服务类:

/// <summary>
/// Summary description for CalendarServices
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class CalendarServices : System.Web.Services.WebService
{
    public CalendarServices()
    {
    }
    [WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string GetEmployees()
    {
        List<object> eventList = new List<object>();
        var emps = ResourceManager.GetAllEmployees();
        foreach (Employee e in emps)
        {
            eventList.Add(
           new
           {
               id = e.EmployeID.ToString(),
               name = e.EmployeName
           }
       );
        }

        JavaScriptSerializer js = new JavaScriptSerializer();
        string strJSON = js.Serialize(eventList);
        return strJSON;
    }
}

在这里被调用:

var calendar = $('#calendar').fullCalendar({
    header: {
        left: 'prev,next today',
        center: 'title',
        right: ''
    },
    defaultView: 'resourceNextWeeks',
    numberOfWeeks: 5,
    weekends: false,
    editable: true,
    selectable: true,
    minTime: 8,
    maxTime: 16,
    refetchResources: true,
    selectHelper: true,
    resources: 'CalendarServices.asmx/GetEmployees'
        ,
    events: [
        {

我不知道为什么这是不工作。也许我不了解web服务?

在这个例子中，他们调用resources.php，它只是回显它。

我想要的是如果我去到calendarservices。asmx/GetEmployees

我想在我的浏览器中看到这个:

[
{
"name":"Resource 2",
"id":"resource2"
},
{
"name":"Resource 1",
"id":"resource1"}
]

纯文本就可以了。目前，如果我在浏览器中尝试这个url，它会崩溃。

我能做什么?

感谢

崩溃:

让WebService只返回纯文本JSON

您是否可以检查fiddler以查看您的请求类型是POST还是GET，您可能必须在代码中添加额外的位。即

[WebInvoke(Method="POST",ResponseFormat=WebMessageFormat.Json)]
