C# 使用asp.net调用需要Cookie的web服务

我正试图使用HTML敏捷包来抓取律师的名单。该站点使用Ajax来填充名称，因此我在服务器端没有任何运气。我注意到该站点正在调用一个web服务，所以我尝试从我的应用程序调用同一个web服务

我正在使用以下代码，但它返回一个内部服务器错误500，我怀疑这是因为我需要会话cookie？（因为如果我禁用Cookie，站点将无法工作）

有人能帮忙吗

private static string WebServiceCall()
{

    WebRequest webRequest = WebRequest.Create("http://www.dlapiper.com/FCWSite/DlaPiperWS/Attorneys.asmx?op=FindAttorneys");
    HttpWebRequest httpRequest = (HttpWebRequest)webRequest;
    httpRequest.Method = "POST";
    httpRequest.ContentType = "text/xml; charset=utf-8";
    httpRequest.Headers.Add("SOAPAction: http://tempuri.org/");
    httpRequest.ProtocolVersion = HttpVersion.Version11;
    Stream requestStream = httpRequest.GetRequestStream();
    //Create Stream and Complete Request             
    StreamWriter streamWriter = new StreamWriter(requestStream, Encoding.ASCII);
    string request = "<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><FindAttorneys xmlns='FCWSite.FCWSite.DlaPiperWS'><scFirstName></scFirstName><scLastName>A</scLastName><scKeyword></scKeyword><scOfficesGUID></scOfficesGUID><scSpokenLanguagesGUID></scSpokenLanguagesGUID><scServicesGUID></scServicesGUID><scRegionGUID></scRegionGUID><scSchoolGUID></scSchoolGUID><scAdmissionGUID></scAdmissionGUID><scLevelGUID></scLevelGUID><strLanguageGUID>7483b893-e478-44a4-8fed-f49aa917d8cf</strLanguageGUID><strCountry>global</strCountry><returnUntranslated>true</returnUntranslated><sortBy>name</sortBy><page>0</page></FindAttorneys></soap:Body></soap:Envelope>";

    streamWriter.Write(request);
    streamWriter.Close();
    //Get the Response    
    HttpWebResponse wr = (HttpWebResponse)httpRequest.GetResponse();
    StreamReader srd = new StreamReader(wr.GetResponseStream());
    string resulXmlFromWebService = srd.ReadToEnd();
    return resulXmlFromWebService;
}

如我在评论中所述。。我在我的项目中添加了authority.asmx url作为web参考

这样做时，我让web引用的命名空间为'com.dlapiper.www'

以下内容在vb.net中，表示标准的默认页面。类com.dlapiper.www.Attorneys表示连接的上下文

请注意，Attorneys.FindAttorney返回一个字符串值

另外，您可以从代码中的buffer和array.convertAll尝试中看到，我尝试了不同的编码。。如果尝试调用FindAtorney而不添加cookie容器和以下cookie。。您将错误地得到一个SOAP异常，指出本地化GUID不在正确的输入中

我在代码中留下了一些不相关的部分，因为我是逆变编程的爱好者

事实上，该参数不能为空，但函数实际上没有使用它。。cookie名称：值为

VB.NET

您是否尝试过将其作为web引用添加到您的项目中。这相当简单。这真的很有帮助，而且效果很好，谢谢！
