从ExtJS框架连接到Web服务和WCF服务 [英] Connecting to web services and wcf services from ExtJS framework

问题描述

我正在使用以下ExtJS框架代码从WebService中获取数据

I am using the following ExtJS framework code to fetch data from WebService

Ext.Ajax.request({
  method: 'GET',
  url:                         'http://192.168.0.98/webservices/WebService.asmx/checkuser',
  jsonData : Ext.encode(param),
  headers: { 'Content-Type': 'application/json;charset=utf-8' },
  success: function (response, request) {
      alert('hit!') ;
  },
  failure: function (response, request) {
      alert('not hit!');
  }
});

服务方法如下

The service method is as below

[WebMethod]
      [ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = true)]
      public string checkuser(string myString)
      {
        return "true"
      }

该服务是可访问的，但从ExtJs中的上述代码调用时，它将失败.

请让我知道是否有任何错误.

The service is accessible but it fails when called from above code in ExtJs.

Please let me know of if there are any mistakes.
