How to make restful service? #4487

manojreddy created 6 years ago

I have implemented a service which has some get, post, update and delete methods.

I want to make this service restful.

Here is my service code.

public class TestAppService : MyProjectAppServiceBase, ITestAppService
{

	public async Task CreateTest(TestDetailsDto input)
	{
	
	}

	public PagedResultDto<FetchTestDetails> GetSearchTest(FetchTestDetails searchInput)
	{
	
	}

	public TestDetailsDto GetTestDetailsForEdit(EntityDto input)
	{
	}

	public async Task UpdateTest(TestDetailsDto input)
	{
	}

	public async Task DeleteTest(EntityDto input)
	{
	}

	public ListResultDto<FetchTestDetails> GetAllCurrencies()
	{
	}

}

so instead of >http://localhost:22742/api/services/app/Test/GetTestDetailsForEdit?Id=1 url should be something like >http://localhost:22742/api/services/app/Currency?Id=1 for get api.

for >http://localhost:22742/api/services/app/Test/CreateTest it should be something like >http://localhost:22742/api/services/app/Test for post api.

for> <a class="postlink" href="http://localhost:22742/api/services/app/Test/DeleteTest?Id=1">http://localhost:22742/api/services/app ... eTest?Id=1</a> it should be >http://localhost:22742/api/services/app/Test?Id=1

From the ASP.NET Core documentation's Application Services as Controllers section:

You can use any ASP.NET Core attributes to change the HTTP methods or routes of the actions. This requires you to add a reference to the Microsoft.AspNetCore.Mvc.Core package.

[HttpPost("api/services/app/Test")] public async Task CreateTest(TestDetailsDto input)

I tried with all method, I'm able to run the server-side code. But when I run Refresh.bat file. and then run npm start. It gives the following error. so I think the reason could be that Swagger is not able to differentiate between these methods.

I tried the below code.

[HttpPost("api/services/app/Test")] public async Task CreateTest(TestDetailsDto input) [HttpDelete("api/services/app/Test")] public async Task DeleteTest(EntityDto input) [HttpGet("api/services/app/Test")] public async Task GetTest(EntityDto input) [HttpPut("api/services/app/Test")] public async Task UpdateTest(TestDetailsDto input)

Do I need to add some extra configuration? Please help

I think the reason could be that Swagger is not able to differentiate between these methods.

Try running Web.Host project.

Yes, Of course I have run the Web.Host project, it running and generating methods.

So, Swagger is able to differentiate between these methods.

NSwag requires some configuration: <a class="postlink" href="https://github.com/RSuter/NSwag/issues/756">https://github.com/RSuter/NSwag/issues/756</a>

manojreddy created 6 years ago

How to open this configuration UI which is mentioned in the github link provided by you, I'm able to see the only service.config.nswag file with a text "operationGenerationMode": "MultipleClientsFromPathSegments", so what should I set value for "operationGenerationMode" instead of "MultipleClientsFromPathSegments", or do I need to delete this line? Is there any side effect of this?

aaron created 6 years ago

Try "MultipleClientsFromOperationId".

I do not know if there is any side effect. Try and you will know. As you already know, ASP.NET Zero does not use that setting.

manojreddy created 6 years ago

@Aaron I agree, But AspNetZero should support restful service because nowadays its must in APIs.

manojreddy created 6 years ago

MultipleClientsFromOperationId not working, giving more than 100 error on npm start. Could you please try the same scenario on your local machine and come up with a proper solution with some test entity, because support for restful service has to be there in abp framework.

Hi,

Can you try this ?

[Route("api/services/app/Test")]
[HttpPost]
public async Task CreateTest(TestDetailsDto input)

[Route("api/services/app/Test")]
[HttpDelete]
public async Task DeleteTest(EntityDto input)

[Route("api/services/app/Test")]
[HttpGet]
public async Task GetTest(EntityDto input)

[Route("api/services/app/Test")]
[HttpPut]
public async Task UpdateTest(TestDetailsDto input)

It seems like Nswag supports it.

Tried, but its also not working.

[Route("api/services/app/Test")] [HttpPost] public async Task CreateTest(TestDetailsDto input) [Route("api/services/app/Test")] [HttpDelete] public async Task DeleteTest(EntityDto input) [Route("api/services/app/Test")] [HttpGet] public async Task GetTest(EntityDto input) [Route("api/services/app/Test")] [HttpPut] public async Task UpdateTest(TestDetailsDto input)

Do I need to make any other change also ?

Hi,

I have just tried it with ABP's Angular 5 template and it seems like it's working.

Here is the app service and it's interface definition:

public class TestAppService : SwagResterAppServiceBase, ITestAppService
{
    [Route("api/services/app/Test")]
    [HttpPost]
    public Task CreateTest(TestDetailsDto input)
    {
        throw new NotImplementedException();
    }

    [Route("api/services/app/Test")]
    [HttpDelete]
    public Task DeleteTest(EntityDto input)
    {
        throw new NotImplementedException();
    }

    [Route("api/services/app/Test")]
    [HttpGet]
    public Task GetTest(EntityDto input)
    {
        throw new NotImplementedException();
    }

    [Route("api/services/app/Test")]
    [HttpPut]
    public Task UpdateTest(TestDetailsDto input)
    {
        throw new NotImplementedException();
    }
}

public interface ITestAppService: IApplicationService, ITransientDependency
{
    
    Task CreateTest(TestDetailsDto input);

    
    Task DeleteTest(EntityDto input);

    
    Task GetTest(EntityDto input);

    
    Task UpdateTest(TestDetailsDto input);
}

public class TestDetailsDto
{

}

After doing that, I was able to see below methods on swagger (in the screenshot).

Then, running refresh.bat generated service proxies without an error. Only thing is method names are testPut, testPost, testGet and testDelete.
