Question

创建了一个Wcf Restful服务并托管在本地服务器中。另一个用户试图通过ajax调用从HTML5页面使用WCF Rest服务。但总是抛出失败的消息

配置设置：

1. WCF Rest服务托管在http://jtl_109.com/mob/AppService.svc/GetUserAuthendication 2.处理HTML5应用程序并将其部署在另一台服务器上。网址为http://jtl_110.com/SampleApplication.html

WCF托管配置设置：

<configuration>
  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />

    <!--

      -->
    <directoryBrowse enabled="true" />
    <handlers accessPolicy="Read, Execute, Script" />
  </system.webServer>

</configuration>

ajax调用是

        var data = { 'logindetails': { 'UserName': UN, 'Password': PW } };
        var st = JSON.stringify(data);
        debugger;
        $.ajax({
            type: "POST",
            url: "http://jtl_109/mob/AppService.svc/GetUserAuthendication",
            data: st,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (result) {
                ServiceSucceeded(result);
                //// Play with response returned in JSON format
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(jqXHR + "-" + textStatus + "-" + errorThrown);
            }


        });

任何人都可以建议如何从其他网站使用WCF重置服务吗？

Answer 1

检查服务器上的端口是否未被防火墙阻止。一种简单的方法是只需在本地机器的浏览器地址栏中键入Web服务的URL - http：// ServerName：8001 / ServiceClass / ServiceMethod

如果您收到404错误或类似错误，请检查防火墙设置（入站）以查看该端口是否已打开。但是，如果您在浏览器中得到了良好的响应，那么您就知道它不是防火墙。

好的，所以这是一个非常简单的htm / JavaScript程序，我写作测试工具来ping WCF Web服务。

 <title>SOAP JavaScript Client Test</title>     
 <script type="text/javascript">

 function Ping() {             
 //set up varable
 var sContent;
 sContent=  "<SoapXML><Your Content></XML>";

 var xmlhttp =  new XMLHttpRequest();
 xmlhttp.open('POST', Demo.URL.value, true);  

 xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4||xmlhttp.readyState == 0) {
    //alert("Ready state: " + xmlhttp.readyState.toString());
    if (xmlhttp.status == 200) {
        //alert("good");
        Demo.pingresponse.value = "Response: " +xmlhttp.responseText;
    }
    if (xmlhttp.status !=200){
        //alert("bad");
        Demo.pingresponse.value = "Error: " +xmlhttp.status.toString() +"  response text:  " +xmlhttp.responseText;
    }
} else {
    //alert("readystate bad");
}
 }

    //send request    

xmlhttp.setRequestHeader("POST http:localhost:8085/ServiceName  HTTP/1.1"); 
xmlhttp.setRequestHeader("VsDebuggerCausalityData","uI8ACQAA"); 
xmlhttp.setRequestHeader("SOAPAction","\"http://SoapRequestHeader\""); 
xmlhttp.setRequestHeader("Host","localhost:8085"); 
xmlhttp.setRequestHeader("Expect","100-continue"); 
xmlhttp.setRequestHeader("Accept-Encoding","gzip, deflate"); 
xmlhttp.setRequestHeader("Connection","Keep-Alive"); 
xmlhttp.setRequestHeader("Content-Length","639");                   
xmlhttp.setRequestHeader("Content-type", "text/xml; charset=utf-8"); 
xmlhttp.send(sContent);                  
 }

</script> 
</head> 
<body>     
<form name="Demo" action="" method="post">         
<div>
Web Service URL (i.e. http://ServerName:8085/ServiceName <br />
<input id="URL" type="text" size="140" value="http:/ /localhost:8085/ServiceName " />
<br />             
<input type="button" value="Ping" onclick="Ping();" /><br />
<textarea id="pingresponse"cols="100" rows="10">
</textarea> <br />     
</div>     
</form> 
</body> 
<html>

显然，这不适用于您的网站，但通过对网址，端口和预期内容进行一些调整，这可能是一个很好的起点。

无法通过ajax调用访问服务器中托管的Wcf服务，但可以访问本地计算机中托管的相同Wcf服务
