Access WCF service through HTTP

Question

Access WCF service through HTTP

I wrote a very simple WCF project in Visual Studio:

IBookStore:

using System.Collections.Generic; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Web; namespace BookStore { [ServiceContract] public interface IBookStore { [OperationContract] [WebGet] List<Book> GetBooksList(); [OperationContract] [WebGet(UriTemplate = "GetBook/{id}")] // The value of UriTemplate defines the name that the // client should use to turn to the function Book GetBookById(int id); [OperationContract] [WebInvoke(UriTemplate = "AddBook/{name}", Method = "PUT")] void AddBook(string name); [OperationContract] [WebInvoke(UriTemplate = "UpdateBook/{id}/{name}", Method = "POST")] void UpdateBook(int id, string name); [OperationContract] [WebInvoke(UriTemplate = "DeleteBook/{id}", Method = "DELETE")] void DeleteBook(int id); } [DataContract] public class Book { int id; string name; [DataMember] public int ID { get { return id; } set { id = value; } } [DataMember] public string Name { get { return name; } set { name = value; } } } }

BookStoreImpl:

 using System.Collections.Generic; using System.ServiceModel; using System.ServiceModel.Activation; namespace BookStore { [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] public class BookStoreImpl : IBookStore { public void AddBook(string name) { using (var db = new BookStoreContext()) { Book book = new BookStore.Book { Name = name }; db.Books.Add(book); db.SaveChanges(); } } public void DeleteBook(int id) { try { using (var db = new BookStoreContext()) { Book book = db.Books.Find(id); db.Books.Remove(book); db.SaveChanges(); } } catch { throw new FaultException("Something went wrong"); } } public Book GetBookById(int id) { using (var db = new BookStoreContext()) { return db.Books.Find(id); } } public List<Book> GetBooksList() { List<Book> allBooks = new List<Book>(); try { using (var db = new BookStoreContext()) { IEnumerator<Book> booksEnum = db.Books.GetEnumerator(); booksEnum.Reset(); while (booksEnum.MoveNext()) { allBooks.Add(booksEnum.Current); } } } catch { throw new FaultException("Something went wrong"); } return allBooks; } public void UpdateBook(int id, string name) { try { using (var db = new BookStoreContext()) { Book book = db.Books.Find(id); book.Name = name; db.SaveChanges(); } } catch { throw new FaultException("Something went wrong"); } } } }

My WebConfig file:

 <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </configSections> <appSettings> <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" /> </appSettings> <system.web> <compilation debug="true" targetFramework="4.5.2" /> <httpRuntime targetFramework="4.5.2" /> <httpModules> <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" /> </httpModules> </system.web> <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="MyServiceBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebBehavior"> <webHttp /> </behavior> </endpointBehaviors> </behaviors> <services> <service behaviorConfiguration="MyServiceBehavior" name="BookStore.BookStoreImpl"> <endpoint address="http://localhost:8080/bookservice/" binding="wsHttpBinding" contract="BookStore.IBookStore" /> <endpoint address="" behaviorConfiguration="WebBehavior" binding="webHttpBinding" contract="BookStore.IBookStore"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel> <!-- <system.serviceModel> <services> <service name="BookStore.BookStoreImpl"> <endpoint address="http://localhost:8080/bookservice" behaviorConfiguration="restfulBehavior" binding="webHttpBinding" bindingConfiguration="" contract="BookStore.IBookStore" /> <host> <baseAddresses> <add baseAddress="http://localhost:8080/bookservice" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="restfulBehavior"> <webHttp /> </behavior> </endpointBehaviors> </behaviors> <protocolMapping> <add binding="basicHttpsBinding" scheme="https" /> </protocolMapping> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel> --> <system.webServer> <modules runAllManagedModulesForAllRequests="true"> <remove name="ApplicationInsightsWebTracking" /> <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" /> </modules> <!-- To browse web app root directory during debugging, set the value below to true.

I also created a database, attached it to the project with the .mdf file, compiled and launched the project, and I can see the timer working in the right corner of the screen after the project starts. Then I will open my browser, enter in the address field: http: // localhost: 8080 / bookservice / GetBooksList and press enter, and instead I will get an error page. It doesn't seem like my requests ever get to the server in the first place. Can someone help me understand why?

Here's the error:

EDIT: I noticed that if I set a breakpoint somewhere and started, I see the following error in the “WCF Test Client” window that appears: “Error : Unable to get metadata from http: // localhost: 59250 / BookStoreImpl.svc If this is the Windows (R) Communication Foundation service that you have access to, please check that you have enabled metadata publishing at the specified address.

You can make this change to make sure basic binding works.

 <service behaviorConfiguration="MyServiceBehavior" name="BookStore.BookStoreImpl"> <endpoint address="" behaviorConfiguration="WebBehavior" binding="basicHttpBinding" bindingConfiguration="HttpBinding" contract="BookStore.IBookStore"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service>

It sounds like a problem with your WCF hosting.

The WCF service must be running inside some host. This can be a console application, an ASP.NET application, a Windows service, etc.

Before attempting to access the URL http: // localhost: 8080 / bookservice / , did you deploy your service as an IIS application with the specified address?

Most likely, you just run the application under debugging in Visual Studio. In this case, you should check that the project URL is configured correctly. Open the project properties, the tab "Web". What is the address in the Project Url edit box?

By default, VS puts localhost: there some random port, for example: http: // localhost: 38577 / . And in your case, the port is most likely 59250, which is evident from the error

Error: Unable to get metadata from http: // localhost: 59250 / BookStoreImpl.svc

If so, and you want to stick with your Web.config, change this value to http: // localhost: 8080 / bookservice / , click Create Virtual Directory and restart the debugging session, then try GetBooksList method GetBooksList .

Access WCF service through HTTP

Server error in application "/".

No protocol binding matches the specified address http: // localhost: 8080 / bookservice / . Protocol associations are configured at the site level in the IIS or WAS configuration.
