JQuery调用WCF(非宿主IIS服务)的问题，显示Method not allowed.

yespie 2012-01-31 01:33:25

我想写个WCF，不想布署在IIS上，想用windows服务或宿主在WPF里。现在的问题是用GET方式求请WCF没有问题，但是用POST方式就有问题，先说一下代码是从网上搜来的，我做了一些小小的改动，代码大概如下：

注：
我在IE中用这个地址访问：http://127.0.0.1:3721/employees/InsRow
会显示：Method not allowed.

这个是js的跨域问题啊。服务端需要配置

我是用这个js调用的：



        function callServer() {

            var id = Number($("#id").val());

            var title = String($("#title").val());

            var content = String($("#content").val());



            $.ajax({

                cache: false,

                async: true,

                type: "POST",

                dataType: "json",

                url: "http://127.0.0.1:3721/employees/InsRow",

                data: '{"title":"' + title + '"}',

                contentType: "application/json;charset=utf-8",

                success: function (msg) {

                    var a = eval('(' + msg + ')');

                    if (String(a.d).length > 0) { alert(a.d); }

                    else { alert("服务器超时"); }

                }

            });



        }

谢谢Sandy945，我看了你Blog上WebMessageBodyStyle文章，我现在改动了这两个文件，然后我在IE中用这个地址访问：http://127.0.0.1:3721/employees/InsRow
仍然显示：Method not allowed.
是不是我还有什么地方没改正确，不好意思，有空时，再帮我一把，谢谢！

在IE中访问是get 方式，你需要延续之前的ajax post 或者 form post 的方式

BodyStyle = WebMessageBodyStyle.WrappedRequest,

改成BodyStyle = WebMessageBodyStyle.Bare试一下
[/Quote]

谢谢，终于有人回答了

host.Open();
会有异常：
Operation 'InsertRow' of contract 'IEmployees' specifies multiple request body parameters to be serialized without any wrapper elements. At most one body parameter can be serialized without wrapper elements. Either remove the extra body parameters or set the BodyStyle property on the WebGetAttribute/WebInvokeAttribute to Wrapped.
