使用Jquery和Soap-XML连接到WCF Web服务

Question

我有一个简单的WCF Web服务,我试图用jquery和SOAP-XML(dataType:"xml")连接.但是当我发送我的请求时,我从服务器得到"BAD REQUEST Error 400".这是我的SOAP-XML:

var soapMessage =
            '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"> \
             <soap:Header> \
             <Action soap:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://tempuri.org/IService/HelloWorld</Action> \
            </soap:Header> \
            <soap:Body> \
            <HelloWorld xmlns="http://tempuri.org/"> \
            </HelloWorld> \
            </soap:Body> \
            </soap:Envelope>';

这是我的$ .Ajax:

var productServiceUrl = 'http://localhost:3523/Service.svc/HelloWorld';
    $.ajax({
                url: productServiceUrl,
                type: "POST",
                dataType: "xml",
                data: soapMessage,
                complete: endSaveProduct,
                contentType: "text/xml; charset=\"utf-8\"",
                async: true,
                error: function (xhr, textStatus, errorThrown) {
                    alert(errorThrown);

                }

            });

这里是请求和响应的详细信息(我在谷歌浏览器中跟踪这个):

和我的响应标题

请求负载:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">                  <soap:Header><Action soap:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/IService/HelloWorld</Action>                 </soap:Header><soap:Body><HelloWorld xmlns="http://tempuri.org/"></HelloWorld></soap:Body> </soap:Envelope>

如果我的WCF Web服务:

[OperationContract]
    [WebInvoke(Method = "POST",
                 BodyStyle = WebMessageBodyStyle.Wrapped,
                 ResponseFormat = WebMessageFormat.Xml,
                 RequestFormat = WebMessageFormat.Xml)]
    String HelloWorld();

Answer 1

我找到了方法.我使用这个解决方案:这是我的Web服务接口:

public interface IService
{
    [OperationContract]
    //[WebGet(UriTemplate = "/data?id={value}", ResponseFormat = WebMessageFormat.Json)]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    string GetData(int value);

}

这是我在Web服务中对此功能的启示:

public string GetData(int value)
    {
        return string.Format("You entered: {0}", value);
    }

这是连接到WCF Web服务的脚本:

<script type="text/javascript">



    $(document).ready(function () {
        var bhRequest = "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">" +
            "<s:Body>" +
            "<GetData xmlns=\"http://tempuri.org/\">" +
            "<value>10</value>" +
            "</GetData>" +
            "</s:Body>" +
        "</s:Envelope>";
        $("#btnWCFBasicHttp").click(function () {
            $.ajax({
                type: "POST",
                url: "Service.svc",
                data: bhRequest,
                timeout: 10000,
                contentType: "text/xml",
                dataType: "xml",
                beforeSend: function (xhr) {
                    xhr.setRequestHeader("SOAPAction", "http://tempuri.org/IService/GetData");
                },
                success: function (data) {
                    $(data).find("GetDataResponse").each(function () {
                        alert($(this).find("GetDataResult").text());
                    });
                },
                error: function (xhr, status, error) {
                    alert(error);

                }
            });
        });
    });


</script>

记住WCF(url: "Service.svc")在我的html页面附近.
