下午好。我并不是要碰这个线程，但是已经过了一个多月，而且我似乎无法获得任何职位或获得工作请求。我已经看过（并尝试合并）这么多预先编写的解决方案，但是每一次似乎都出现了我无法解决的问题。任何帮助将不胜感激。非常感谢。
解决我的问题：我一直在尝试使用简单的“ Hello消息”创建默认的WCF服务，该服务根据Filburt的建议接受POST数据，而我什么也做不了。任何帮助，将不胜感激。我正在尝试为CRM 2013编写一个测试Web服务，该服务将从窗体上的iframe触发，并调用位于同一crm服务器上的启用AJAX的WCF Web服务。该消息将需要向该服务发送POST（未获取）消息。该服务似乎返回“ 400”错误：“ XMLHttpRequest无法加载http://localhost/PasswordResetter/Resetter.svc。无效的HTTP状态代码400”。我已经尝试浏览了30多个左右的“教程”以及此处的说明，Web，msdn，但我不知道我似乎在做错什么，或者为什么它不起作用。我无法从iframe或自定义html页面（我创建的服务和html页面都位于本地主机）上运行。
最后，如果此问题在某种程度上是“此网站的格式不正确”，请向我指出如何/为什么这样做，以便我对其进行适当的修改。预先感谢您的所有帮助。
下面是我的界面：
namespace PasswordResetter
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IResetter" in both code and config file together.
[ServiceContract]
public interface IResetter
{
[OperationContract()]
string test(string a, string b);
}
}
方法如下：
public class Resetter : IResetter
{
[WebInvoke(Method = "POST", //was POST
BodyStyle = WebMessageBodyStyle.Bare, //This means that our JSOn will map directly to our parameters with no additional processing??
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "/Test")]
public string test(string a, string b)
{
//return "Success!: " + a + " " + b;
string myJsonString = (new JavaScriptSerializer()).Serialize("Hello World! A: " + a + " b: " + b);
return myJsonString;
}
}
这是我正在尝试使用的Javascript：
$(document).ready(function () {
$('#iframesubmit').click(function () {
//var obj = { username: $("#txtuser").val(), name: $("#txtname").val() };
var obj = '[{ username: $("#password_old").val(), name: $("#password_new").val() }]';
$.ajax({
type: "POST", //was POST
contentType: "application/json; charset=utf-8",
url: "http://localhost/PasswordResetter/Resetter.svc",
//data: "",
data: JSON.stringify(obj),
//data: "{ 'a': '" + $("#password_old").val() + "', 'b': '" + $("#password_new").val() + "'}",//JSON.stringify(obj),
dataType: "json",
success: function (data) {
alert("Successfully register");
document.getElementById("results").value = "Response: " + data; //service.responseText;
$("#iframesubmit").click();
},error: function (xhr)
{
window.alert('error: ' + xhr.statusText);
}
});
});
});
最后是我的web.config：
<?xml version="1.0"?> <configuration> <appSettings> <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /> </appSettings> <system.web> <compilation debug="true" targetFramework="4.5" /> <httpRuntime targetFramework="4.5"/> </system.web> <system.serviceModel>

代码中有一些问题...
首先，使用WebInvoke修饰方法通常是在
接口不在主类中
其次是方法名称(test)，而UriTemplate="/Test"应该是
相同。应该如下UriTemplate="/Test"
public string Test(string a, string b){ string myJsonString = (new JavaScriptSerializer()).Serialize("Hello World! A: " + a + " b: " + b); return myJsonString;}
在您对此方法进行ajax调用时出现问题
替换以下行
网址：“ http://localhost/PasswordResetter/Resetter.svc”
与
网址：“ http://localhost/PasswordResetter/Resetter.svc/Test”
希望这会有所帮助。
