Question

我尝试了以下方法来检索Web服务的结果：

<%  
    Dim oRequest
    Set oRequest = Server.CreateObject("MSXML2.ServerXMLHTTP")

    oRequest.setOption(2) = SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS
    oRequest.setTimeouts 10000, 10000, 10000, 10000

    msURL = "http://[0.0.0.0]/contale/customer.asmx/GetInfoFromWhitesPages"

    msSOAP = "<?xml version=""1.0"" encoding=""utf-8"" ?>"
    msSOAP = msSOAP & "<s:Envelope xmlns:s=""http://schemas.xmlsoap.org/soap/envelope/"">"
    msSOAP = msSOAP & "<s:Body>"
    msSOAP = msSOAP & "<GetInfoFromWhitesPagesResponse   xmlns=""http://[0.0.0.0]/Contale/"">"
    msSOAP = msSOAP & "<phone>4504656253</phone>"
    msSOAP = msSOAP & "</GetInfoFromWhitesPagesResponse>"
    msSOAP = msSOAP & "</s:Body>"
    msSOAP = msSOAP & "</s:Envelope>"

    oRequest.Open "POST", msURL, False
    oRequest.setRequestHeader "Content-Type", "text/xml"
    oRequest.setRequestHeader "SOAPAction", "[Some Url]"
    oRequest.send msSOAP
    Response.Write oRequest.ResponseBody
%>

但结果显示：???????????????????????????????????????????????????????????????????????????? ???†???????????????????????????????????†？4 ???????? ???????????????????????????

我也尝试了以下内容：

<html>
<head><title></title></head>
<body>
<%
    Dim objHTTP, strEnvelope
    Set objHTTP = Server.CreateObject("Microsoft.XMLHTTP")
    strEnvelope = "<?xml version='1.0' encoding='utf-8'?>"
    strEnvelope = strEnvelope & "<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/'>" 
    strEnvelope = strEnvelope & "<soap:Body>"
    strEnvelope = strEnvelope & "<GetInfoFromWhitesPagesResponse xmlns='http://[0.0.0.0]/Contale'>"
    strEnvelope = strEnvelope & "<phone>4504656253</phone>"
    strEnvelope = strEnvelope & "</GetInfoFromWhitesPagesResponse>"
    strEnvelope = strEnvelope & "</soap:Body></soap:Envelope>"

    Dim url
    url = "http://[0.0.0.0]/contale/customer.asmx"
    With objHTTP
        .Open "post", url, False
        .setRequestHeader "Content-Type", "text/xml; charset=utf-8"
        .setRequestHeader "SOAPAction", "http://[0.0.0.0]/contale/GetInfoFromWhitesPagesResponse"
        .send strEnvelope
    End With

    Dim strResponse
    strResponse = objHTTP.responseXML.Text
    If (strResponse = "") Then
        Response.Write("Invalid user")
    Else
        Response.Write(strResponse)
    End If
%>
</body>
</html>

但是，我得到了这个：

soap:ClientSystem.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: http://[0.0.0.0]/contale/GetInfoFromWhitesPagesResponse. at System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouteRequest() at System.Web.Services.Protocols.SoapServerProtocol.Initialize() at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

以下是我的WebService的代码：

using System;
using System.Net;
using System.Text.RegularExpressions;
using System.Web.Services;

namespace CustomersInfo
{
    /// <summary>
    /// Summary description for WebService1
    /// </summary>
    [WebService(Namespace = "http://[0.0.0.0]/Contale/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {
        [WebMethod]
        public CustomerData GetInfoFromWhitesPages(string phone)
        {
            var customer = new CustomerData();

            var webClient = new WebClient();
            webClient.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36 Other");

            var content =                       webClient.DownloadString("http://www.whitepages.com/phone/" + phone);

            const string infoStart = "<div class=\"address-card\">";

            if (content.Contains(infoStart))
            {
                var startPos = content.IndexOf("<div class=\"address-card\">", StringComparison.Ordinal) + infoStart.Length;
                var endPos = content.IndexOf("</div>", startPos, StringComparison.Ordinal);
                var info = content.Substring(startPos, endPos - startPos).TrimEnd().TrimStart();

                info = info.Replace("\n", "").Replace("<p>", "").Replace("</p>", "");
                string[] tabInfo = Regex.Split(info, "<br />");
                string name = tabInfo[0];
                string address = tabInfo[2];
                string city = tabInfo[3].Split(' ')[0].Replace(",", "");
                string province = tabInfo[3].Split(' ')[1];
                string zip = tabInfo[3].Split(' ')[2] + " " + tabInfo[3].Split(' ')[3];

                customer.Name = name;
                customer.Address = address;
                customer.City = city;
                customer.Province = province;
                customer.Zip = zip;
            }
            return customer;
        }

        public struct CustomerData
        {
            public string Name;
            public string Address;
            public string City;
            public string Province;
            public string Zip;
        }
    }
}

任何帮助将不胜感激。

谢谢

首先添加codepage = 65001 第二个告诉浏览器你发送utf-8

？显示字符是因为浏览器和服务器不知道如何处理响应

从经典ASP调用c＃webservice
