WCF - IIS Hosting

Lưu trữ dịch vụ WCF trong IIS (Dịch vụ Thông tin Internet) là một quá trình từng bước. IIS Hosting được minh họa chi tiết bên dưới với mã hóa mong muốn cũng như ảnh chụp màn hình để hiểu quy trình.

Step 1- Khởi động Visual Studio 2012 và nhấp vào Tệp → Mới → Trang web. Chọn “Dịch vụ WCF” và Vị trí là http. Điều này sẽ lưu trữ dịch vụ trong IIS. Bấm OK.

Step 2 - Đoạn mã đằng sau giao diện được đưa ra bên dưới.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to 
// change the interface name "IService" in both code and config file 
// together.

[ServiceContract]
Public interface IService {
   [OperationContract]
   String GetData(int value);

   [OperationContract]
   CompositeType GetDataUsingDataContract(CompositeType composite);

   // TODO: Add your service operations here
}

// Use a data contract as illustrated in the sample below to add 
// composite types to service operations.

[DataContract]
Public class CompositeType {
   Bool boolValue = true;
   String stringValue = "Hello ";

   [DataMember]
   Public bool BoolValue {
      get { return boolValue; }
      set { boolValue = value; }
   }

   [DataMember]
   Public string StringValue {
      get { return stringValue; }
      set { stringValue = value; }
   }
}

Step 3 - Đoạn mã đằng sau tệp lớp được đưa ra bên dưới.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to 
// change the class name "Service" in code, svc and config file 
// together.

Public class Service : IService {
   Public string GetData(int value) {
      Return string.Format("You entered: {0}", value);
   }

   Public CompositeType GetDataUsingDataContract(CompositeType composite) {
      if(composite == null) {
         thrownewArgumentNullException("composite");
      }
      
      if(composite.BoolValue) {
         composite.StringValue += "Suffix";
      }
      return composite;
   }
}

Step 4- Tệp dịch vụ (.svc) chứa tên của dịch vụ và mã đằng sau tên tệp. Tập tin này được sử dụng để biết về dịch vụ.

<%@ ServiceHost Language = "C#" Debug = "true" Service = "Service" 
   CodeBehind = "~/App_Code/Service.cs" %>

Step 5- Cấu hình phía máy chủ được đề cập trong tệp cấu hình. Ở đây, chỉ đề cập đến một điểm cuối được định cấu hình thành 'wsHttpBinding'; chúng ta cũng có thể có nhiều điểm cuối với các ràng buộc khác nhau. Vì chúng tôi sẽ lưu trữ trong IIS, chúng tôi chỉ sử dụng liên kết http.

Step 6- Bạn cần đề cập đến tên tệp dịch vụ, cùng với Địa chỉ được đề cập trong tệp cấu hình. Ảnh chụp màn hình của IIS được đưa ra ở đây.

Nhấp vào Bắt đầu → chạy → inetmgr sẽ mở cửa sổ sau.

Step 7 - Chạy ứng dụng sẽ xuất hiện màn hình sau.
