jQuery ajax調(diào)用webservice注意事項(xiàng)
jquery ajax調(diào)用webservice(C#)要注意的幾個(gè)事項(xiàng):
1、web.config里需要配置2個(gè)地方
<httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> </httpHandlers>
在<system.web></system.web>之間加入
<webServices>
<protocols>
<add name="HttpPost" />
<add name="HttpGet" />
</protocols>
</webServices>
2.正確地編寫webserivce的代碼
/// <summary>
/// UserValidate 的摘要說明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允許使用 ASP.NET AJAX 從腳本中調(diào)用此 Web 服務(wù),請(qǐng)取消對(duì)下行的注釋。
