上个月，我一直在忙着创建一个包含多个函数的.NET Web服务和一个用html和Javascript编写的网站，它充当用户界面并使用JSON调用webservice方法。 Web服务返回了JSON响应，它确实运行良好。然后我专注于web服务来完成所有功能，并且没有打开网站大约3周。
今天我完成了网络服务，并决定继续在网站上工作。但是当我打开它时，我发现JSON通信不再起作用了......
该网站仍然发送JSON请求（使用网络嗅探器检查）但Web服务不再响应，因此它必须是Web服务端的问题。
我试图整整一天找到问题，但找不到任何东西.. 这里有一些可能有用的代码片段
网络服务标题：
[WebService(Namespace = "http://meijberg.topicus.local/zdfmobiel")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
[System.ComponentModel.ToolboxItem(false)]
public class ZDFMobielWebservice : WebService {

编辑：一些调用webservice的客户端javascript代码：
var xhrGegevens = new XMLHttpRequest();
xhrGegevens.open("POST", "http://meijberg.topicus.local/ZDFMobielWebservice.asmx/getGegevensVerzekerde", true);
xhrGegevens.onreadystatechange = function(){
if (xhrGegevens.readyState === 4) {
var result = eval('(' + xhrGegevens.responseText + ')');
//Functionality
}
}
xhrGegevens.setRequestHeader("content-type", "application/json");
var postData = '{"bsn": "999999999"}';
xhrGegevens.send(postData);
编辑：webservice中的getGevensVerzekerde方法：
[WebMethod]
public VerzekerdeGegevens getGegevensVerzekerde(string bsn)
{
ZorgVerzekerde verzekerde = Dao.GetVerzekerde(Convert.ToInt32(bsn));
VerzekerdeGegevens result = new VerzekerdeGegevens();
result.bsn = verzekerde.Bsn;
result.geboortedatum = verzekerde.Geboortedatum.Value.ToShortDateString();
result.geslacht = Convert.ToString(verzekerde.Geslacht);
result.huisnummer = verzekerde.Huisnummer;
result.naam = verzekerde.Naam;
result.postcode = verzekerde.Postcode;
result.voorletters = verzekerde.Voorletters;
int i = 0;
foreach(ZorgPolisInstantie polisInstantie in verzekerde.PolisInstanties)
{
PolisGegevens gegevens = new PolisGegevens();
gegevens.begindatum = polisInstantie.Begindatum.ToShortDateString();
gegevens.einddatum = polisInstantie.Einddatum.Value.ToShortDateString();
if(polisInstantie.Type == (ZorgPolisInstantie.ZorgPolisType) 1)
{
gegevens.eigenrisico = polisInstantie.EigenRisico;
}
else { gegevens.eigenrisico = 0; }
gegevens.polisnummer = Convert.ToString(polisInstantie.PolisNummer);
gegevens.type = (int) polisInstantie.Type;
result.polisgegevens.Add(gegevens);
}
return result;
}
有谁知道问题可能是什么？
答案 0 :(得分：1)
差不多2天后我发现了问题.... Webservice机器上的病毒扫描程序（AVG Anti Virus）阻止了我对Web服务的所有JSON请求.... ARGGHHHHH !!!
凯夫，感谢您的努力：）答案 1 :(得分：0)
您是否缺少Web服务方法中的以下属性？：
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
当您使用相对URL时会发生什么，例如：
xhrGegevens.open("POST", "ZDFMobielWebservice.asmx/getGegevensVerzekerde", true);
