JQuery AJAX 使用 SOAP Web 服务 [英] JQuery AJAX Consume SOAP Web Service

问题描述

我一直在试验和尝试学习 JQuery，使用 AJAX 来使用我前段时间编写的 SOAP Web 服务.以下是我正在使用的代码:

<form method="post" action=""><div><input type="button" value="Call Web Service" onclick="CallService(); return false;"/>

</表单>

目前，在 Web 服务中调用的方法返回包含类别代码和类别描述的类别系列数组.由于该方法返回 XML，因此我相应地设置了 ajax 查询.但是，当我运行该应用程序时，我收到一个错误"警告框 - 我确定是什么导致了问题.我知道 Web 服务有效，我编写的其他 .NET Web 应用程序每天都会调用它数百次.

任何帮助将不胜感激.

谢谢，

解决方案

尝试设置 processData: false 标志.这个标志默认是 true，我猜 jQuery 是 converting 你的XML 到字符串.

$.ajax({网址:webServiceURL，类型:POST"，数据类型:xml"，数据:soapMessage，过程数据:假，contentType: "text/xml; charset="utf-8"",成功:OnSuccess，错误:OnError});

I have been experimenting and trying to learn JQuery, using AJAX to consume a SOAP web service I had written some time ago. Below is the code I am using:

<script type="text/javascript">
    var webServiceURL = 'http://local_server_name/baanws/dataservice.asmx?op=GetAllCategoryFamilies';
    var soapMessage = '<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><GetAllCategoryFamilies xmlns="http://tempuri.org/" /></soap12:Body></soap12:Envelope';

    function CallService()
    {
        $.ajax({
            url: webServiceURL, 
            type: "POST",
            dataType: "xml", 
            data: soapMessage, 
            contentType: "text/xml; charset="utf-8"",
            success: OnSuccess, 
            error: OnError
        });

        return false;
    }

    function OnSuccess(data, status)
    {
        alert(data.d);
    }

    function OnError(request, status, error)
    {
        alert('error');
    }

    $(document).ready(function() {
        jQuery.support.cors = true;
    });
</script>

<form method="post" action="">
    <div>
        <input type="button" value="Call Web Service" onclick="CallService(); return false;" />
    </div>
</form>

Currently, the method being called in the web service returns an array of category families that contain a category code and a category description. Since the method returns XML, I set the ajax query accordingly. However, when I run the app, I get an 'error' alert box - I am sure what would be causing the problem. I know the web service works, it's called several hundred times a day by other .NET web apps that I've written.

Any help would be greatly appreciated.

Thanks,

Try setting processData: false flag. This flag is true by default and I guess jQuery is converting your XML to string.

$.ajax({
    url: webServiceURL, 
    type: "POST",
    dataType: "xml", 
    data: soapMessage, 
    processData: false,
    contentType: "text/xml; charset="utf-8"",
    success: OnSuccess, 
    error: OnError
});
