我最近遇到了将Javascript请求发布到另一个域的问题.默认情况下,不允许将XHR发布到其他域.

按照http://enable-cors.org/的说明,我在其他域上启用了此功能.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
 <system.webServer>
  <httpProtocol>
    <customHeaders>
      <add name="Access-Control-Allow-Origin" value="*" />
      <add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE,OPTIONS" />
      <add name="Access-Control-Allow-Headers" value="Content-Type" />
    </customHeaders>
  </httpProtocol>
 </system.webServer>
</configuration>

现在一切正常,但是在发回工作200响应之前仍然会返回405响应.

我正在调用(Ajax请求)一个WCF REST服务,该请求是一个跨域请求.

如果我在同一个域中部署我的服务,一切都像奶油一样.最终在生产中,该服务将位于不同的域中.

我正在使用jQuery 1.5.2.我的服务给我一个错误说:

errorThrown: "jQuery15208493315000087023_1334089616458 was not called"
textStatus: "parsererror"

虽然在Firefox中我可以看到JSON值,但执行属于Ajax请求的错误处理程序.

我的Ajax请求是:

function CallService() {
    $.ajax({
        type: "GET", 
        url: "http://SomeService/EmpService.svc/GetValues?dv=1455",
        contentType: "application/json; charset=utf-8",
        dataType: "jsonp", 
        processdata: false,            
        success: function (data) {
            ServiceSucceeded(data);
        },
        error: function (jqXHR, textStatus, errorThrown) {
            debugger;
            alert("Service Error");
            ServiceFailed(jqXHR, textStatus, errorThrown);
        }
    });
}

在WCF服务端,我已将CrossDomainScriptAccess配置为true:

<webHttpBinding>
  <binding name="webHttpBindingWithJsonP"
           crossDomainScriptAccessEnabled="true" />
</webHttpBinding>

我从服务器获得的JSON响应是:

[{"Message": "Stop On Duty", "MessageTime": "\/Date(1334068773893-0500)\/"},
 {"Message": "Start On Duty", "MessageTime": "\/Date(1334068763540-0500)\/"},
