        context.Services.AddStaticHttpClientProxies(
            typeof(MyClientAppModule).Assembly
        );
    }

I guess it should be like this: (document is misspelled)

typeof(MyClientAppContractsModule).Assembly

instead of

typeof(MyClientAppModule).Assembly

Hi,

With Contracts generate all the classes/enums/other types in the client side (including application service interfaces) , This is also the default behavior of the generate-proxy command.

There is no problem and the MyClientapp should add project references Application and MyApplication.Http.Client. it will generate all needed classes(Dtos, Interfaces, Proxies)

I run this command :

abp generate-proxy -t csharp -u https://localhost:44382/

output:

[10:15:13 INF] ABP CLI (https://abp.io)
[10:15:14 INF] Version 5.3.3 (Stable)
[10:15:15 WRN] ABP CLI has a newer stable version 7.0.1, please update to get the latest features and fixes.
[10:15:15 WRN]
[10:15:15 WRN] Update Command:

[10:15:20 INF] Create ClientProxies\ServicePurchaseClientProxy.cs
[10:15:20 INF] Create ClientProxies\ServicePurchaseClientProxy.Generated.cs

Only created ClientProxy.cs and ServicePurchaseClientProxy.Generated.cs files. Did not create dtos, interfaces etc. and also didn't give any error or warning. Project not build after proxy generation because of missing interfaces and dtos.

Hi,

You should make sure the project version and ABP CLI are the same.

Because your project version is v5.2.1. Without Contracts is suited for you.

I reproduced in v7.0.1 ((server and client)) but I got this output

System.Net.Http.HttpRequestException: Response status code does not indicate success: 500 (Internal Server Error).

Could you share the error logs too? (server)

ademaygun created one year ago

Create a new solution via Abp Suite (SampleA)
Create new Entity (Book) via Abp Suite (suite creates Entity,Dtos, ApplicationService) and run it.
Create a second new solution via Abp Suite (SampleB)
Create proxy with contracts:(on SampleB)

Open a command-line terminal in the root folder of your client project (.csproj) and type the following command: With Contracts abp generate-proxy -t csharp -u http://localhost:53929/(SampleA project API url)

Note: I haven't run the SampleB project yet because I'm in the proxy generate phase. so no error logs is generated.

I got this error (command line error):

You need to run the AuthServer(https://localhost:44361).

I am sorry. I run AuthServer. But only 3 files generated.

Hi,

I used the project your provided and it's working for me.

You should make RemoteService to true.
0

ademaygun created one year ago

It worked successfully when RemoteService(IsEnabled = true) . Thanks. Well,can't proxy classes be used in domain layer? For example I would like to use it in a manager class. I know that I need to move these classes(contracts and interfaces) to the domain in order to use them in the domain layer.

Hi, I need to call a remote service in a bg-job,How can I do that?

could you give more detail. thanks.

but we don't recommend you to do this

Hi,

You just need to inject the service in the job

could you give more detail. thanks.

Because the remote service actually is the application layer, The domain layer should not reference the application layer.

Better to use repositories instead of remote services in domain services, but it's a new topic.

I think the main problem has been solved, so I close this.
