非常感谢任何帮助。
概述: 我有一个.Net解决方案,2个项目。一个托管Web服务,一个调用Web服务。 Web服务接受整数id参数,并返回格式为JSON的人名 以下是Fiddler的原始输出:
HTTP/1.1 200 OK
Server: ASP.NET Development Server/10.0.0.0
Date: Wed, 16 Oct 2013 16:51:18 GMT
X-AspNet-Version: 4.0.30319
Cache-Control: private, max-age=0
Content-Type: application/json; charset=utf-8
Content-Length: 35
Connection: Close
{"PersonName":"Jane Doe"}
这是基本的Web服务设置:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class PeopleWebService : System.Web.Services.WebService
{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void GetUserName(int ID)
{
try
{
using (EformTstEntities db = new EformTstEntities())
{
JavaScriptSerializer js = new JavaScriptSerializer();
var jsonData = new
{
PersonName = (from i in db.People where i.ID == ID select i.FirstName + " " + i.LastName).FirstOrDefault()
};
string retJSON = js.Serialize(jsonData);
Context.Response.Write(retJSON);
}
}
catch (Exception ex)
{
Context.Response.Write(string.Format("[ERROR: {0}]", ex.Message));
}
}
}
所以,我认为Web服务工作正常而不是问题......
这是我通过ajax对Web服务的基本调用。这时我不想对输出做任何事情,我只是试图在没有错误的情况下调用Web服务。在通话中,我不断进入错误处理功能。有什么想法吗?
<script type="text/javascript">
function getUserName() {
var id = $("#UserID").val();
$.ajax({
url: "http://localhost:1211/Services/PeopleWebService.asmx/GetUserName",
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: "{ID:'" + id + "'}",
success: function (msg) {
alert("this worked");
},
error: function () {
alert("this error");
}
});
return false;
}
</script>
答案 0 :(得分:1)
尝试
data: "{'ID':'" + id + "'}",
并更改错误方法以查看错误详细信息,如下所示
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.status);
alert(xhr.responseText);
alert(thrownError);
}
