Access the WCF Service in Wince

As this article is not a popular article on WinCE development, we recommend that you go to Baidu and Google to find the answer for the basics of WinCE development and WCF development, and then work out how to access WCF in this article. Thank you.

 

Development Environment

IDE: Visual Studio 2008 (not supported currently in 2010, 2012, and 2013)

OS: Win 7 (64-bit)

Tools: ActiveSync win7 v6.1 (the device center provides a network for the Pocket PC 2003 simulator)

Simulator network connection strategy a copy: http://www.jb51.net/softjc/42088.html

This article is not widely used in WinCE development, so please use Baidu.

 

WCF Server

Key code in app. config

<Service behaviorConfiguration = "SystemDispatchServiceForPDABehavior" name = "SystemManageServiceLibrary. SystemDispatchServiceForPDA"> <! -- PDA system allocation --> <endpoint address = "http: // localhost: 20003/SystemDispatchForPDA/SystemDispatchServiceForPDA" binding = "webHttpBinding" contract = "SystemManageServiceLibrary. systemDispatch. ISystemDispatchServiceForPDA "> </endpoint> <! -- Metadata allocated by the PDA system --> <endpoint address = "http: // localhost: 20003/SystemDispatchForPDA/SystemDispatchServiceForPDA/mex "binding =" mexHttpBinding "contract =" IMetadataExchange "/> Service Contract-publish wcf rest (For details, refer to Baidu to search for wcf rest)

[ServiceContract] public interface ISystemDispatchServiceForPDA {// <summary> // PDA obtains cluster information /// </summary> /// <param name = "strPDA_IMEI"> inside the PDA factory no. </param> /// <returns> </returns> [OperationContract] // UriTemplate is actually a url rule for sending requests over http, replace {strPDA_IMEI} with the actual PDA string number. Then you can [WebGet (UriTemplate = "GetClusterInfo/{strPDA_IMEI}")] CLUSTER GetClusterInfo (string strPDA_IMEI );}View Code

 

WinCE

HttpWrapper. cs-encapsulation of Http requests, access the REST service provided by WCF

Public class HttpWrapper {public static string SendRequest (string url) {HttpWebResponse response = null; HttpWebRequest request = WebRequest. create (url) as HttpWebRequest; request. method = "GET"; request. allowWriteStreamBuffering = false; request. keepAlive = true; request. contentType = "application/x-www-form-urlencoded"; // receive the returned page response = request. getResponse () as HttpWebResponse; Stream responseStream = response. getResponseStream (); StreamReader reader = new System. IO. streamReader (responseStream, Encoding. UTF8); string strResult = reader. readToEnd (); reader. close (); response. close (); return strResult ;}}View Code

XmlAdapter. cs-Xml adapter, used to convert Xml into a class

Public class XmlAdapter {public static T ConvertToClass <T> (string strXML) where T: class {XmlSerializer xmlSerializer = new XmlSerializer (typeof (T); MemoryStream reader = new MemoryStream (Encoding. UTF8.GetBytes (strXML); T obj = xmlSerializer. deserialize (reader) as T; reader. dispose (); return obj ;}}View Code

Call Method

        private static string URL = "http://ip:20003/SystemDispatchForPDA/SystemDispatchServiceForPDA/";        public static CLUSTER GetClusterInfo(string strPDA_IMEI)        {            string strResponse = HttpWrapper.SendRequest(URL + "GetClusterInfo/" + strPDA_IMEI);            CLUSTER cluster = XmlAdapter.ConvertToClass<CLUSTER>(strResponse);            return cluster;        }

 

 

Note the following points:

1. Install the Device Center

2. Set the network connection of the simulator.

3. WCF REST

4. WinCE parses the XML returned by WCF and how to splice the access URL
