【问题描述】：
我正在尝试使用此代码访问正在运行的系统进程，它运行良好并显示所有正在运行的进程，但是当我从我的 Visual Studio 2012 发布此内容后，它不显示进程，而是显示一个空白页面，我也禁用了 Windows 和防病毒防火墙，但它也无法正常工作....

xhr.send(Soap_a);
var xmlDoc = xhr.responseXML;

webservice.asmx 文件...
webservice.cs 文件..

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// 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 {
String s1;
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string HelloWorld() {
foreach (System.Diagnostics.Process winProc in System.Diagnostics.Process.GetProcesses())
{
s1 = s1 + String.Format("<font size=3 face=verdana color=red></br><a href=killprocess.htm?code={0}>{0}</a></font>", winProc.ProcessName.ToString());
}
return s1;
}
}
我使用“killprocess.htm”页面来停止任何正在运行的进程。
【问题讨论】：
-
ajax 调用实际上是在访问服务器吗？
-
在 firefox 中运行控制台时，它会显示......主线程上的同步 XMLHttpRequest 已被弃用，因为它会对最终用户的体验产生不利影响。更多帮助xhr.spec.whatwg.orguser.htm:10 TypeError: xmlDoc is null
