Question

我想使用来自clientside的AJAX将JSON对象传递给WCF服务。在Internet Explorer中一切正常，但在Firefox中没有。

在Firefox中我得到 405：方法不允许

这是我将json数据（从客户端脚本）传递到WCF服务...

    $(document).ready(function () {
        var Author = '{ "Id": "A01", "Name": "Ravinder" }';
        $.ajax({
            type: "POST",
            data: JSON.stringify(Author),
            contentType: "application/json; charset=utf-8",
            datatype: "json",
            url: "http://localhost:53905/Service1.svc/AuthorPostByJson",
            success: function (data) {
                alert("success");
            },

            error: function (xmlhttprequest, textstatus, errorthrown) {
                alert(" failed ");
                console.log("error: " + errorthrown);
            }
         });//end of $.ajax
    });

我的WCF服务就像......

     [OperationContract]
            [WebInvoke(Method = "POST",
                UriTemplate = "AuthorPostByJson", 
                ResponseFormat = WebMessageFormat.Json, 
                RequestFormat = WebMessageFormat.Json)]       
            List<Book> GetBooksByAuthor_JSON(Author author);

我的web.config文件......

  <system.serviceModel>
    <services>
      <service behaviorConfiguration="Platform.WebRestful.Service1Behavior"
        name="Platform.WebRestful.Service1">
        <endpoint address="" binding="basicHttpBinding" contract="Platform.WebRestful.IService1">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
      <service behaviorConfiguration="Platform.WebRestful.BookServiceHostRestfulBehavior"
        name="Platform.WebRestful.BookServiceHostRestful">
        <endpoint address="" binding="webHttpBinding" contract="Platform.WebRestful.IBookServiceHostRestful">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Platform.WebRestful.Service1Behavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
        <behavior name="Platform.WebRestful.BookServiceHostRestfulBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
   <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
    </behaviors>
  </system.serviceModel>

Answer 1

最后我在一些文章中找到了答案。他们说跨越任何跨域（站点）HTTP请求，第一个浏览器将发送称为“预检请求”的“OPTIONS”请求... “preflighted”请求首先向另一个域上的资源发送HTTP OPTIONS请求标头，以确定实际请求是否可以安全发送，并且此请求需要适当的标头，说服务允许访问该服务作为回应

为实现这一目标，我们有两个解决方案...... 1）WCF自定义行为 2）修改Global.asax文件的Application_BeginRequest事件。

我跟着第二个...... 解决方案是将 Global.asax 文件添加到WCf服务项目并添加

following code in that,then it perfectly works across any browser...

protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
                HttpContext.Current.Response.End();
            }
        }

使用AJAX从客户端无法在firefox中将JSON对象传递给WCF服务
