Define the exposed REST API interface we want 27 | 28 | ```csharp 29 | public interface IDemoAService : IAutomaticApi 30 | { 31 | /// 32 | /// DemoA api 33 | /// 34 | /// 35 | string Get(); 36 | } 37 | ``` 38 | 39 | We can also define another REST API interface. 40 | 41 | ```csharp 42 | public interface IDemoBService : IAutomaticApi 43 | { 44 | /// 45 | /// DemoB api 46 | /// 47 | /// 48 | string Get(); 49 | } 50 | ``` 51 | 52 | And implement these interfaces. 53 | 54 | ```csharp 55 | public class DemoService : IDemoAService, IDemoBService 56 | ... 57 | ``` 58 | 59 | ## 3. Configure Services 60 | 61 | ```csharp 62 | public void ConfigureServices(IServiceCollection services) 63 | { 64 | services.AddAutomaticApi(op => 65 | { 66 | op.AddApi(); //only generate IDemoAService 67 | 68 | op.AddApi(); //Generate all api interface in DemoService 69 | 70 | op.AddAssembly(Assembly.GetEntryAssembly()); //Generate all api interface in Assembly 71 | }); 72 | } 73 | ``` 74 | 75 | # What a REST api interface? 76 | 77 | You can totally use it as a controller. 78 | 79 | ```csharp 80 | public interface IDemoService : IAutomaticApi 81 | { 82 | /// 83 | /// DemoB api 84 | /// 85 | /// 86 | [Authorize] 87 | [HttpPost] 88 | [Route("...")] 89 | string UpdateAsync(Guid id, [FromBody] RequestModel model); 90 | } 91 | ``` 92 | 93 | However, `[HttpPost]` `[Route]` usually doesn't need to be defined. AutomaticApi will generates `Route` and `HttpMethod` based on the Method name. 94 | 95 | As we all know, some `[Attrbute]` may can't put it on interface like this. 96 | ``` csharp 97 | [Authorize] 98 | public interface IDemoService : IAutomaticApi 99 | ... 100 | ``` 101 | We can do some customization. 102 | ```csharp 103 | [AttributeUsage(AttributeTargets.Class | AttributeTargets.Interface | AttributeTargets.Method, AllowMultiple = true, Inherited = true)] 104 | public class MyAuthorizeAttribute : AuthorizeAttribute 105 | { 106 | } 107 | ``` 108 | If you think this component can help you, please give me a star. 109 | -------------------------------------------------------------------------------- /src/AutomaticApi/AutomaticApiOptions.cs: -------------------------------------------------------------------------------- 1 | using AutomaticApi.Dynamic;
