我正在尝试使用HTML Agility Pack来查找http://www.dlapiper.com/global/people/search.aspx?gLastName=A的律师名单。该站点使用Ajax来填充名称，所以我没有运气这个服务器端。我注意到该网站正在http://www.dlapiper.com/FCWSite/DlaPiperWS/Attorneys.asmx?op=FindAttorneys调用一个Web服务，所以我试图从我的应用程序中调用相同的Web服务。
我正在使用以下代码，但它返回内部服务器错误500，我怀疑是因为我需要一个会话cookie？ （因为如果我禁用cookie，该网站不起作用）
有人可以帮忙吗？
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;
}
答案 0 :(得分：1)
正如我在评论中所述......我在我的项目中添加了Attorney.asmx网址作为网络参考。
这样做时，我让web引用的引用名称为'com.dlapiper.www'。
以下内容位于vb.net中，代表标准默认页面。 com.dlapiper.www.Attorneys类代表连接的上下文。
请注意，Attorneys.FindAttorney返回一个字符串值..
另外，你可以从我的缓冲区和array.convertAll中看到代码尝试，我正在尝试不同的编码..如果你试图调用FindAttorney而不添加cookie容器和以下的cookie ...你会错误地得到一个SOAP异常，说明localizationGUID没有正确输入。
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粉丝。
事实是，该参数不能为空，但实际上并未被函数使用.. cookie名称：值为。
