Consume Web api Http service in MVC solution

Document by Vairavan – ganesanva@hotmail.com – + 919042710472

Create a MVC solution using Code First Approach MVC Entity framework.
Add a Web Api Controller Class as below,

Look on the WebApiConfig.cs how the Routes are made.

The API URL can be routed as both API/Controller/Id and Api/Controller/Action/Id by registering the Routes in Web api config.
Add the Below code in Api Controller(Used for CRUD),

private UsersContext db = new UsersContext();
// GET api/values
public IEnumerable<StudentDetails> GetallStudents()
{
return db.StudentDbset.ToList();
}
// GET api/values/5
public StudentDetails GetStudents(int id)
{
StudentDetails studentdetails = db.StudentDbset.Find(id);
return studentdetails;
}
[HttpPost]
[ActionName(“Delete”)]
// Post api/values/Delete/5
public string DeleteStudents(int id)
{
StudentDetails studentdetails = db.StudentDbset.Find(id);
db.StudentDbset.Remove(studentdetails);
db.SaveChanges();
return “Deleted”;
}
// POST api/values
[HttpPost]
[ActionName(“Post”)]
public void Post([FromBody]string value)
{
}
// PUT api/values/5
public void Put(int id, [FromBody]string value)
{
}
// DELETE api/values/5
public void Delete(int id)
{
}

Screen clipping taken: 02-09-2016 18:44
The Above Api methods can be accessed using below URL,
http://localhost:16842/api/Values
http://localhost:16842/api/Values/5
http://localhost:16842/api/Values/Delete/5
The data can be returned as JSON,Xml or any other format depends on the attribute.

Create a new HTML page in the Solution as index.html

Put below code in Index.html,

<!DOCTYPE html>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<title>Product App</title>
</head>
<body>
<div>
<h2>All Products</h2>
<ul id=”products” />
</div>
<div>
<h2>Search by ID</h2>
<input type=”text” id=”prodId” size=”5″ />
<input type=”button” value=”Search” onclick=”find();” />
<p id=”product” />
</div>
<script src=”http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.3.min.js”></script>
<script>
var uri = ‘/api/values’;
$(document).ready(function () {
// Send an AJAX request
$.getJSON(uri)
.done(function (data) {
// On success, ‘data’ contains a list of products.
$.each(data, function (key, item) {
// Add a list item for the product.
$(‘<li>’, { text: formatItem(item) }).appendTo($(‘#products’));
});
});
});
function formatItem(item) {
return item.studentName + ‘: $’ + item.Age;
}
function find() {
var id = $(‘#prodId’).val();
$.getJSON(uri + ‘/’ + id)
.done(function (data) {
$(‘#product’).text(formatItem(data));
})
.fail(function (jqXHR, textStatus, err) {
$(‘#product’).text(‘Error: ‘ + err);
});
}
</script>
</body>
</html>

Now the MVC Application Works with Controller web api repository and a HTML page.
The output will be,

Consume WCF application in MVC

Document by Ganesan – Ganesanva@hotmail.com – + 919600370429

Create a new MVC application.
Create Connection string in Web.config as below.

Create StudentDetails.cs Class file as below.

[DataContract]
public class StudentDetails
{
[DataMember]
public int Id { get; set; }
[DataMember]
public string StudentName { get; set; }
[DataMember]
public int? Age { get; set; }
}

Create DBContext.Cs file as below

public class UsersContext : DbContext
{
public UsersContext()
: base(“TestConnection”)
{
}
public DbSet<StudentDetails> studentDbset { get; set; }
}

Create ScafFolding and autogenerate Views and controllers.
Make sure the Code now works in DB first approach. After this we are going to change the
data source to consume From WCF.
Create Service Reference as below,

Click OK. Now the service reference will be added as below,

Replace the Controller methods for CRUD as below,

public ActionResult Index()
{
SampleMVC1.ServiceReference1.Service1Client objService = new ServiceReference1.Service1Client();
List<SampleMVC1.ServiceReference1.StudentDetails> objStudentDetails= objService.GetStudentData();
return View(objStudentDetails);
}
[HttpPost]
public ActionResult Create(SampleMVC1.ServiceReference1.StudentDetails studentdetails)
{
if (ModelState.IsValid)
{
SampleMVC1.ServiceReference1.Service1Client objService = new ServiceReference1.Service1Client();
string result= objService.CreateStudentData(studentdetails);
return RedirectToAction(“Index”);
}
return View(studentdetails);
}
//
// GET: /Student/Edit/5
public ActionResult Edit(int id = 0)
{
SampleMVC1.ServiceReference1.Service1Client objService = new ServiceReference1.Service1Client();
SampleMVC1.ServiceReference1.StudentDetails studentdetails = objService.GetStudentDatabyID(id);
if (studentdetails == null)
{
return HttpNotFound();
}
return View(studentdetails);
}
//
// POST: /Student/Edit/5
[HttpPost]
public ActionResult Edit(SampleMVC1.ServiceReference1.StudentDetails studentdetails)
{
if (ModelState.IsValid)
{
SampleMVC1.ServiceReference1.Service1Client objService = new ServiceReference1.Service1Client();
string result = objService.UpdateStudentData(studentdetails);
return RedirectToAction(“Index”);
}
return View(studentdetails);
}

Replace the view First line I.E model reference to point to Service model

Similar for other pages too.

Now the pages will be like below
