Web 服务从 SOAP 请求中获取空数组，而不是字符串数组

Question

我有一种情况，我通过 Ajax 发送带有字符串数组的 SOAP 请求，请求成功传递给 Web 服务，但是反序列化的数组为空。

我的 ASP.Net WebService 具有以下合同：

[WebService(Namespace = "http://someCompany.com/WebServices/TCWS/Agent")]
public class AgentService : WebService  

使用以下 API：

[WebMethod(Description = "my action description", MessageName = "MyAction")]
public Result MyAction(string[] items)  

我使用以下代码通过 AJAX (Javascript) 发出请求：

AgentService.prototype.DoSoapAjax = function (methodName, data, successHandler, errorHandler, state) {
    // Need to use local variable so ajax request will be able to process the guid variable
    var currGuid = window.AgentGUID;

    var response = $.ajax({
        type: "POST",
        contentType: "text/xml; charset=utf-8",
        methodName: methodName,
        url: this.AgentServiceUrl,
        data: data,
        async: this.Async,
        beforeSend: function (req, methodName) {
            var soapActionURI = "http://someCompany.com/WebServices/TCWS/Agent/" + this.methodName;
            req.setRequestHeader("SOAPAction", soapActionURI);
            req.setRequestHeader("AgentGUID", currGuid);
        },
        success: function (xml, textStatus) {
            if (successHandler != null) {
                var response = xml.lastChild.firstChild.firstChild.firstChild;
                successHandler(state, $.xml2json(response), textStatus);
            }
        },
        error: function (xmlHttpRequest, textStatus, errorThrown) { if (errorHandler != null) errorHandler(state, xmlHttpRequest, textStatus, errorThrown); }
    });

    if (!this.Async) {
        var syncResponse = new Object();
        syncResponse.response = response;
        syncResponse.json = $.xml2json(response.responseText);
        return syncResponse;
    }

    return response;
};  

这就是我调用 DoSoapAjax 的方式：

AgentService.prototype.MyAction= function (items, successHandler, errorHandler, state) {
    var items = "<items arrayType='string[]'><item xsi:type='string'>first text</items><item xsi:type='string'>second text</items></items>"

    var methodName = "MyAction ";
    var soapXml = "<?xml version='1.0' encoding='utf-8'?><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/soap/envelope/'><soap:Body>"
    soapXml += "<" + methodName + " xmlns='http://someCompany.com/WebServices/TCWS/Agent'>";
    soapXml += items;
    soapXml += "</" + methodName + "></soap:Body></soap:Envelope>";

    var response = this.DoSoapAjax("MyAction", soapXml, successHandler, errorHandler, state);
    return response;
};

SOAP 请求如下：

<?xml version='1.0' encoding='utf-8'?>
    <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/soap/envelope/'>
        <soap:Body>
            <MyAction xmlns='http://someCompany.com/WebServices/TCWS/Agent'>
                <items xsi:type='string'>first text</items>
                <items xsi:type='string'>second text</items>
            </MyAction>
        </soap:Body>
</soap:Envelope>  

当我调试 Web 服务时，我可以看到我得到了 MyAction 方法，但是 items 是一个空数组，而不是包含 2 个字符串的数组...

我的 SOAP 请求有问题吗？

数据对象不是作为字符串数组传递的，而是作为单独的字符串参数添加到正文中。正确的 SOAP 应该如下所示：

<?xml version='1.0' encoding='utf-8'?>
    <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/soap/envelope/'>
        <soap:Body>
            <MyAction xmlns='http://CosmoCom.com/WebServices/TCWS/Agent'>
                <items arrayType="string[]">
                    <item xsi:type='string'>first text</items>
                    <item xsi:type='string'>second text</items>
                </items>
            </MyAction>
        </soap:Body>
</soap:Envelope>

我想把数据做成一个可以使用的数组

var itemArray = jQuery.makeArray(data);

我找到了一些解决方案，但是我不明白为什么它会起作用，因为我找不到任何文档。
我已将 SOAP 请求更改为以下内容：

<?xml version='1.0' encoding='utf-8'?>
    <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/soap/envelope/'>
        <soap:Body>
            <MyAction xmlns='http://someCompany.com/WebServices/TCWS/Agent'>
                <items>
                    <string>first text</string>
                    <string>second text</string>
                </items>
            </MyAction>
        </soap:Body>
</soap:Envelope>  

有人可以发布关于此的解释或文档，以便更清楚吗？看起来当我传递一个 element 时，我输入了它的 name，而当它是 array 时，我输入了它的 type。我在一些小型谷歌文档中找到了该解决方案...
谢谢大家
