通过ajax将数据发布到数据库中.显示501内部错误 [英] Post data into database via ajax. displays 501 internal error

问题描述

我正试图将我的asp.net网络表单中的数据发布到数据库中.我的asp.net服务(shoppingcart_service.asmx)中有这个

i am trying to post data from my asp.net webform into database. i have this in my asp.net service (shoppingcart_service.asmx)

 [WebMethod] // 
        public void RegisterSubscriber(string Email)
        {
            new OnlineShopTableAdapters.NewsletterSubscribersTableAdapter().Insert(Email, DateTime.Now);
     //database code


        }

这是我的html

  <input type="button" onclick="saveData()" id="btnSave" value="Subscribe"  >

这是我的Ajax代码，我将其放在名为apps.js的文件中并链接到我的页面

this is my ajax code, which i put in a file called apps.js and linked to my page

//已更新！ 函数saveData(){

//updated ! function saveData() {

 function saveData() {

    var SubscriberEmail = $("#Email").val();
    $.ajax({
        type: "Post",
        url: "shoppingcart_service.asmx/RegisterSubscriber",
        data: '{"Email":"' + SubscriberEmail + '"}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            alert(response.status + ' ' + response.statusText);
        },
        error: function (request, status, error) {

        }

    });

}

但是该值未发布到我的数据库中，请考虑单击订阅按钮后，我在chrome控制台中收到的错误

but the value doesn't get posted to my database consider the error i got in chrome's console, after clicking the subscribe button

推荐答案

我在一个项目中做过同样的事情，并且效果很好..我唯一看到的区别是我的web方法返回string/bool值，并且该webservice类具有ScriptService属性.

I have done same thing in one of my projects and it works well..the only difference I can see is that my webmethods return string/bool values and also the webservice class has ScriptService attribute.

参见下文:

 [System.Web.Script.Services.ScriptService]
 public class ajaxpost : WebService
 {
     [WebMethod]
     public string Callback(string txbFirstname)
     {
     }
 }

而脚本方面是:

    $.ajax({
        type: "POST",
        url: "/Services/ajaxpost.asmx/Callback",
        data: '{"txbFirstname":"' + txbFirstname + '"}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(result) {

        },
        error: function(request, status, error) {

        }

    });
