Service调用方式

注：网页请求的XML需要加命名空间，直接引用不需要。

一、网页请求

请求方式有四种，需要开启才能使用。

1、Get

private static string HttpGet(string Url, string postDataStr)

        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url + (postDataStr == "" ? "" : "?") + postDataStr);

            request.Method = "GET";

            request.ContentType = "text/html;charset=UTF-8";

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            Stream myResponseStream = response.GetResponseStream();

            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));

            string retString = myStreamReader.ReadToEnd();

            myStreamReader.Close();

            myResponseStream.Close();

            return HttpUtility.HtmlDecode(retString);

        }

2、Post

private static string HttpPost(string Url, string postDataStr)

        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);

            request.Method = "POST";

            request.ContentType = "application/x-www-form-urlencoded";

            request.ContentLength = Encoding.UTF8.GetByteCount(postDataStr);

            //request.CookieContainer = cookie;

            Stream myRequestStream = request.GetRequestStream();

            StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312"));

            myStreamWriter.Write(postDataStr);

            myStreamWriter.Close();

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            //response.Cookies = cookie.GetCookies(response.ResponseUri);

            Stream myResponseStream = response.GetResponseStream();

            var xml = new XmlSerializer(typeof(Stream));

            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));

            string retString = myStreamReader.ReadToEnd();

            myStreamReader.Close();

            myResponseStream.Close();

            return HttpUtility.HtmlDecode(retString);

        }

3 4、SOAP

private String HttpSoap(string serviceUrl,string guid)

        {

            //构造soap请求信息 （具体参考webService的说明）

            StringBuilder soap = new StringBuilder();

            soap.Append("");

            soap.Append("<soap12:envelope xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">");

            soap.Append("");

            soap.Append("<getprojectmdinfobyguidresponse xmlns=\"http://tempuri.org/\">");

            soap.Append("");

            soap.Append(guid);

            soap.Append("");

            soap.Append("");

            soap.Append("");

            soap.Append("");

            //发起请求

            Uri uri = new Uri(serviceUrl);

            WebRequest webRequest = WebRequest.Create(uri);

            webRequest.ContentType = "application/soap+xml; charset=utf-8";

            webRequest.Method = "POST";

            using (Stream requestStream = webRequest.GetRequestStream())

            {

                byte[] paramBytes = Encoding.UTF8.GetBytes(soap.ToString());

                requestStream.Write(paramBytes, 0, paramBytes.Length);

            }

            //响应

            var projInfo = "";

            WebResponse webResponse = webRequest.GetResponse();

            using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))

            {

                projInfo = myStreamReader.ReadToEnd();

            }

            return HttpUtility.HtmlDecode(projInfo);

        }

二、直接引用

1、右键引用→服务引用→输入服务地址→引用

2、using namespace

3、引用后会自动在当前项目的配置文件中加入一段节点。如果引用项目不是主项目。需要复制到主项目的配置文件中。

同时可以根据需要修改配置文件，比如请求大小等。

    

      

        <binding name="ServiceNameSoap" maxReceivedMessageSize="6553600">

          

        

      

    

    

      <endpoint address="http://ServiceUrl/ServiceName.asmx"

          binding="basicHttpBinding" bindingConfiguration="ServiceNameSoap"

          contract="ServiceName.ServiceNameSoap" name="ServiceNameSoap" />

    

  

4、同时.csproj工程文件会多两句，同上，若当前非主项目，需要同步到主项目中的工程文件中：

5、调用 ServiceNameSoapClient 类
