Question

以下是我的WCF服务的WSDL代码，如何从jQuery Ajax调用服务Directory.svc？我尝试通过调用'Directory.svc / LoadStaff'和'Directory.svc / Directory / LoadStaff'，但我收到HTTP 400错误。

以下是我用来调用服务的jQuery代码：

$.ajax({
url: 'http://localhost:59440/Directory.svc/LoadStaff',
type: 'GET',
dataType: "json",
success: function (data) {
//nothing to do yet
},
error: function (SOAPResponse) {
    console.log('oops');
}

}）;

看起来您正在对基于SOAP的服务执行HTTP GET请求，该服务本质上总是期望基于XML的SOAP信封的HTTP POST。

由于您的客户端使用javascript，您最好的选择可能是使用WCF WebGet或将框架切换到ASP.NET WEB API，为服务添加基于REST的端点。

如果出于某种原因无法实现上述目标，那么您的javascript客户端实际上可以进行SOAP调用。请注意，这将使您的客户端实现很难维护，并且还会遇到其他问题，例如错误处理等。

但如果必须这样做，这可能会帮助您朝着正确的方向前进：

var yourSoapEnvelope = '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/X......'

$.ajax({
url: yourURL,
type: "POST",
dataType: "xml",
data: yourSoapEnvelope,
complete: doStuff,
contentType: "text/xml; charset=\"utf-8\""
});

鉴于以下WSDL如何调用方法LoadStaff（）？
