使用需要cookie的asp.net调用Web服务

asp.net c# html-agility-pack web-services

我正在尝试使用HTML Agility Pack来查找律师名单, 网址http://www.dlapiper.com/global/people/search.aspx?gLastName=A 。该站点使用Ajax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上调用Web服务,所以我试图从我的应用程序调用相同的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;
}

一般承认的答案

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引用的引用名称空间为'com.dlapiper.www'。

以下是在vb.net中,表示标准的默认页面。 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..

此外,您可以从我的缓冲区和array.convertAll尝试代码中看到,我正在尝试不同的编码..如果您尝试调用FindAttorney而不添加cookie容器和以下cookie ...您将错误地获取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。
