基于C#的Rest接口服务端

为了能够在桌面端软件中简单方便的对外提供RestApi接口，参考Java SpringMVC框架使用C#语言编写了一个简易RestApi服务器框架，目前支持：

• 静态页面处理
• GET/POST/PUT/DELETE请求
• 支持返回JSON
• 支持路由方法
• 支持自定义过滤器
• 服务器返回数据支持gzip压缩
• 支持Component变量自动注入
• 支持Component自动扫描
• 支持Filter过滤器
• GET/POST支持查询参数，POST支持body数据（JSON格式）
• 注解支持
• Component
• WebFilter
• RequestMapping
• Autowired
• RequestBody
• RequestParam

示例一 静态页面映射

 
			

				
				

				

					
					
new RestApplicationServer().run(new RestConfiguration {
    StaticFileConfigurations = new List<StaticFileConfiguration>() { new StaticFileConfiguration("/e", "E:\\"), new StaticFileConfiguration("/f", "F:\\")
  }
 });

				

			

示例二 自定义路由

1.添加Controller

						

						

							
							
[Component("PersonController")]
public class PersonController {
    [Autowired]
    public PersonService personService;
    private ILogger logger = LoggerFactory.GetLogger();

    [RequestMapping("GET","/api/person/list")]
    public List<Person> GetPersonList()
    {
        return personService.GetPersonList();
    }

    [RequestMapping("GET", "/api/person")]
    public Person GetPerson([RequestParam("id")]int id)
    {
        logger.Debug("id:"+id); return personService.GetPerson((int)id);
    }

    [RequestMapping("POST", "/api/person")]
    public string Create([RequestBody] Person person)
    {
        logger.Info("person:" + person.ToString());
        return "ok";
    }
}

						

2.添加Service

								

									
									

									

										
										
[Component("PersonService")]
public class PersonService
{
    private ILogger logger = new ConsoleLogger();
    public List<Person> GetPersonList() {
        return TestData.PersonList;
    }
    public Person GetPerson(int id)
    {
        return TestData.PersonList.Find(x => x.id == id);
    }
    public void Create(Person person)
    {
        logger.Debug(person.ToString());
    }
}

									

								

3.启动服务

controller和service上增加Component注解后，服务启动时会进行自动扫描

											

												
												

												

													
													
class Program
{
    static void Main(string[] args)
    {
        new RestApplicationServer().run();
    }
}

												

											

示例三 增加Filter

1. 添加一个计算接口处理耗时的filter

													

														
														

														

															
															
[WebFilter(1, "/")]
public class StopWacthFilter : IFilter
{
    public void Filter(HttpRequest request,ref HttpResponse response, ProcessChain chain, int nextIndex)
    {
        Stopwatch stopwatch = new Stopwatch();

        stopwatch.Start();
        chain.doFilter(request,ref response, nextIndex);
        stopwatch.Stop();
        Console.WriteLine(request.Method + " "+request.Path+ ", 耗时："+(stopwatch.ElapsedMilliseconds).ToString()+"ms");
     }
}

														

													

自定义filter上增加WebFilter注解后，服务启动时会进行自动扫描
