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.

我试图从JQuery调用C#WCF SOAP Web服务.

该服务托管在端口80上的IIS上,客户端从端口81上的Apache运行,两者都来自localhost.所以我陷入跨源请求.

1. 使用Chrome,我得到预期的结果,但查看网络流量,它显示OPTIONS请求返回错误400 Bad Request,但是下一个POST请求成功:

2. 使用Firefox,引发错误(JavaScript警报显示null | error |).似乎POST请求未发送,因为OPTIONS请求失败:

3. 使用IE,一切正常,好像是来自同一个来源......我没有看到任何OPTIONS请求:

来自界面的公开功能:

namespace Test
{
    [ServiceContract]
    public interface IMathService
    {
        [OperationContract]
        String HelloWorld();
    }
}

服务配置(Web.config):

<services>
  <service name="Test.MathService" behaviorConfiguration="ServiceBehavior">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:80/WCFtest/service.svc" />
      </baseAddresses>
    </host>
    <endpoint address="/soap" binding="basicHttpBinding" contract="Test.IMathService" />
    <endpoint address="/rest" binding="webHttpBinding" contract="Test.IMathService" behaviorConfiguration="WEB" />
  </service>
</services>
