Web Services by Using Service Stack Web Service Framework

Install Service Stack from NuGet

All dependencies will be installed too

After installation, you will several references have been included

 

On-line document of Service Stack

http://servicestack.net, click the Documentation button

Click Create your first webservice

This page is for non MVC application, so scoll down to the link for MVC

Click the link below:

https://github.com/ServiceStack/ServiceStack/wiki/Run-servicestack-side-by-side-with-another-web-framework.

Copy the content of Web.config

Other steps

 

Implement in Visual Studio

Add “Api” folder and one class, “HelloService.cs”.

Code separate into 3 parties:

1. Service

2. Request

3. Response, the name is always requestName+Response

Using the service that we just created

 

Testing on Web Service

The default web site URL has error, it is no doubt

Has to add “/api” to see available web services, but it’s still fail so far

Check the error message, we forgot to new an AppHost() in Application_Start() in Global.asax

So add the code, “new ProteinTrackerAppHost().Init();” in Application_Start() function

Now it works, and showing following screen.

One operation shows, Hello. It supports different format, XML, JSON, JSV, CSV, …etc.

Click JSON, for example.

Two routes are available for this service

Using /api/hello/xxx to consume the web service

In json format

In xml format

Redis Client API Overview

 

4 Types of RedisClients

You can choose the layer of abstraction to work with

1. ICacheClient:

2. IRedisNativeClient: same command in C# and native client but in binary data format

3. IRedisClient: higher level of redis client

4. IRedisTypedClient:

 

Using NuGet to Install

 

Example 1, IRedisNativeClient

 

Example 2, IRedisClient

 

Example 3, IRedisTypedClient

 

Example 4, Transcation

 

Example 5, Pub and Sub

ASP.NET SignalR – Clients

Outline

1. Hub Consumers

2. jQuery Clients

3. .NET Clients

 

1. Hub Consumers

 

2. jQuery Client

First approach:

jQuery with Proxy – part I

Demo 1 – UI preparation

1. Must include both javascript files, jQuery.js & SignalR.js BEFORE 2. SignalR/Hubs

2. Must include SignalR/Hubs

3. Include personal javascript file

 

Demo 2 – SignalR Utilities (signalr.exe) to generate server.js file

 

jQuery with Proxy – part II

 

jQuery with Proxy – part III

 

Demo 3 – Chat.js

Explain above 3 points:

1. chat.client.newMessage –> newMessage() is a client event method that can be called from server side. Define client behavior first

2. Once button click, trigger server side event by this line of code chat.server.sendMessage(xxx), so all clients will run client side event newMessage() which defined in previous step

3. Enforce to use longPolling as transport negociation protocal and start hub connection

 

 

Demo – Join Group

Demo – Monitor (test fail)

 

Second approach:

jQuery without Proxy File

Demo

 

3. .NET Client

Demo – Win Form
