A company project requires an app for Android and server interaction, and the simpler the server, the better. It is better not to use IIS.

WCF meets this requirement. Its host can either be hosted in IIS or in a common application.Program.

Let's introduce my work below.

Create a project

Create the following three projects:

Service: A class library project.ServicesAndContracts(Contract) is put in it, note to addSystem. servicemodelAndSystem. servicemodel. WebTwo references.

Host: A command line application that carries the service. Naturally, you must add a reference to the service.

Client: A winform application for interacting with the host to test the service availability.

Write a service

The Service consists of two parts: Service and contract:

View code

 
[Servicecontract]Public InterfaceIservice {[operationcontract] imageinfo getimageinfo (StringID); [operationcontract] stream getimagecontent (StringID );}
 

View code

 Public   Class Service: iservice {[webget (uritemplate = "  /Imageinfo/{ID }/  " , Responseformat = Webmessageformat. JSON)]  Public Imageinfo getimageinfo ( String  ID ){  Return   New  Imageinfo {ID = ID, name ="  Noname  "  , };} [Webget (uritemplate = "  /Imagecontent/{ID }/  "  )]  Public Stream getimagecontent ( String  ID) {weboperationcontext. Current. outgoingresponse. contenttype = "  Image/PNG "  ;  String File = path. Combine (environment. currentdirectory, "  Picture.png  "  );  Return  File. openread (File );}} 

The definition of complex types is also required. Pay attention to adding the classDatacontractFeature to add attributes to be serializedDatamemberFeatures:

View code

[Datacontract]Public ClassImageinfo {[datamember]Public StringId {Get;Set;} [Datamember]Public StringName {Get;Set;}}
 

Write host

HostCodeYou can simply start the WCF Service:

View code

Static VoidMain (){Using(VaRHost =NewServicehost (Typeof(Imageservice. Service. Service) {Host. open (); console. writeline ("The service has been started!"); Console. Read ();}}
 

Then add the configuration file app. config:

View code

 <?  XML version = "1.0" ?>  <  Configuration  >    <  System. servicemodel  >      <  Services  >        <  Service  Name  = "Imageservice. Service. Service"  >         <  Host  >            <  Baseaddresses  >              <  Add  Baseaddress  = "Http: // MAID: 8888 /"  />            </  Baseaddresses  >          </ Host  >          <  Endpoint  Address  = ""  Binding  = "Webhttpbinding"  Contract  = "Imageservice. Service. iservice"  Behaviorconfiguration  = "Behavior"  >          </ Endpoint  >        </  Service  >      </  Services  >      <  Behaviors  >        <  Endpointbehaviors  >          < Behavior  Name  = "Behavior"  >            <  Webhttp  />          </  Behavior  >        </  Endpointbehaviors  >      </  Behaviors >    </  System. servicemodel  >  <  Startup  >    <  Supportedruntime  Version  = "V4.0"  SKU  = ". Netframework, version = v4.0"  />  </ Startup  >  </  Configuration  > 

Note: Fill in the complete service class name and contract Interface Name:

Write Client

The client has no difficulty, that is, communication with the host. Directly paste the Code as follows:

View code

  void btngetimageinfo_click (Object sender, eventargs E) {var DATA = getdata ("/imageinfo/1/"); var S = encoding. default. getstring (data); imageinfo. TEXT = s;} void btngetimagecontent_click (Object sender, eventargs e) {var DATA = getdata ("/imagecontent/1/"); Using (var ms = new memorystream (data )) {var image = new Bitmap (MS); imagecontent. image = image;} byte [] getdata (string URI) {var request = (httpwebrequest) webrequest. create ("http: // 127.0.0.1: 8888" + URI); var response = request. getresponse (); Using (var ms = new memorystream () {var buffer = new byte [1, 10240]; using (var ns = response. getresponsestream () {int I = NS. read (buffer, 0, buffer. length); While (I> 0) {Ms. write (buffer, 0, I); I = NS. read (buffer, 0, buffer. length) ;}} return Ms. toarray () ;}
