ASP. NET MVC4 WEBAPI application Client Access server side

I. Description

Client project type is designed as: WinForm (WinForm form project type)

The server-side project type is designed as: ASP. Mvc4 WEBAPI

This is divided into two scenarios: project run and Debug.

Run:

This situation refers to the server-side project has been developed, you can deploy it to IIS (http://localhost:8748) in parentheses is the server-side deployment to IIS access address, the client access to the server to use

Debugging:

When debugging, you can create the client and server side under the same solution. Debugging steps: Run the server project first, then check the server's access address in the tray

Assign the server access address to my client, run the Client Access server side.

Ii. creating a server-side project

First open the VS2012 development environment software,

1. Create a Blank Solution

Steps: File-new-project-Other project Types-Visual Studio Solution

The solution is named: MyTest

2. Create server-side

Right-click the solution created in the previous step-add-New project-"Web-->asp.net MVC4 Web application (named: MyServer)--" Web API (MVC project template)

3. Add WEBAPI Controller

Right-click the Controllers folder in the MyServer project-"Add-" controller (named User)--"Empty API Controller"

Adding a method to a controller

[HttpGet]

public string GetUserInfo (string userName, String PassWord)

{

if (UserName = = "Admin" && PassWord = = "123456")

{

Return "Success";

}

Else

{

Return "Failed";

}

}

Also add custom routing rules in file Webapiconfig

Config. Routes.maphttproute (

Name: "MyApi",

Routetemplate: "Api/{controller}/{action}/{key}",

defaults:new {key = routeparameter.optional}

);

Iii. Creating clients (client)

Right-click the solution "MyTest"-"Add-" New project-"windows-" Windows Forms Application (named: myclient)

The design interface on the default form Form1 is as follows:

The background code for form Form1 is as follows:

Using System;

Using System.Collections.Generic;

Using System.ComponentModel;

Using System.Data;

Using System.Drawing;

Using System.Linq;

Using System.Net.Http;

Using System.Text;

Using System.Threading.Tasks;

Using System.Windows.Forms;

Namespace MyClient

{

public partial class Form1:form

{

Public Form1 ()

{

InitializeComponent ();

}

private void btnSubmit_Click (object sender, EventArgs e)

{

String userName = TxName.Text.Trim ();

String PassWord = TxPwd.Text.Trim ();

String url = @ "http://localhost:47673/api/File/GetUserInfo?userName=" + userName + "&password=" +password;

HttpClient client = new HttpClient ();

Httpresponsemessage response = client. Getasync (URL). Result;

String str= Response. Content.readasstringasync (). Result;

MessageBox.Show (str);

}

}

}

Note In the client-side reference assembly System.Net.Http; Reference method: Right-click the Reference folder in MyClient-"Add Reference-" assembly

The using System.Net.Http is also added in the background code of Form1;

Four, commissioning

1, in vs2012, select the server-side project, after the compilation passed, "Start execution (not debugging)"

2, view the server's access address, such as

Right-click IIS Express in the Tray

Replace the URL of the access address in the client backend code with:

String url = @ "http://localhost:8748/api/User/GetUserInfo?userName=" + userName + "&password=" +password;

3. Start the client project

In the solution, select the client project (set as Startup Project), MyClient start debugging
