jquery ajax CORS 跨域訪問 WebService

JS代碼:

 

var word = document.getElementById(word).value;$.ajax({    type: POST,    contentType: application/x-www-form-urlencoded,    url: http://localhost:12805/WebService.asmx/HelloWorld,    data: 'data=' + word,    dataType: 'text',    success: function(result) {        alert(success:  + result);    },    error: function(result, status) {        alert(error:  + status);    }});

C# WebService代碼:

 

 

[WebService(Namespace = weburl)][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 WebService : System.Web.Services.WebService{    [WebMethod]    public void HelloWorld(string data)    {        this.Context.Response.AddHeader(Access-Control-Allow-Origin, *); // CORS 跨域訪問        this.Context.Response.Write(data); // 返回字串格式    }}

WebService 預設 return 返回 XML 格式,但是使用上述方式是以字串形式返回。
