mc86 created one year ago

UI type: Blazor-server
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): yes
Exception message and stack trace:
Steps to reproduce the issue:"

i flowed the doc and added the chat module in a **microservice ** . add the volo.chat to the {projectname}.blazor then added the

  app.Use(async (httpContext, next) =>
            {
                var accessToken = httpContext.Request.Query["access_token"];

                var path = httpContext.Request.Path;
                if (!string.IsNullOrEmpty(accessToken) &&
                    (path.StartsWithSegments("/signalr-hubs/chat")))
                {
                    httpContext.Request.Headers["Authorization"] = "Bearer " + accessToken;
                }

                await next();
            });

to the blazor server app. but now there is an error

Hi,

You don't need to add these codes.

Here are my steps:

Add chat packages to the service. for example: add chat packages to the AdministrationService.

Run abp add-package Volo.Chat.Application command in the *.AdministrationService.Application folder

Run abp add-package Volo.Chat.Application.Contracts command in the *.AdministrationService.Application.Contracts folder

Run abp add-package Volo.Chat.Domain command in the *.AdministrationService.Domain folder

Run abp add-package Volo.Chat.Domain.Shared command in the *.AdministrationService.Domain.Shared folder

Run abp add-package Volo.Chat.EntityFrameworkCore command in the *.AdministrationService.EntityFrameworkCore folder

Run abp add-package Volo.Chat.HttpApi command in the *.AdministrationService.HttpApi folder

Run abp add-package Volo.Chat.HttpApi.Client command in the *.AdministrationService.HttpApi.Client folder

Run abp add-package Volo.Chat.HttpApi.Client command in the *.AdministrationService.HttpApi.Client folder

Configure database tables

Add builder.ConfigureChat(); to the OnModelCreating method of AdministrationServiceDbContext class

Make AdministrationServiceDbContext implement the IChatDbContext interface

Open AdministrationServiceEntityFrameworkCoreModule and add options.ReplaceDbContext<IChatDbContext>();

Use dotnet ef ... command to add migrations & update database.

Configure Blazor project

Add <PackageReference Include="Volo.Chat.Blazor.Server" Version="6.0.1" /> to csproj file.

Add <PackageReference Include="Volo.Chat.SignalR" Version="6.0.1" /> to csproj file.

Add [DependsOn(typeof(ChatSignalRModule), typeof(ChatBlazorServerModule))] to the *BlazorModule

Configure gateway
{ "ServiceKey": "Chat Service", "DownstreamPathTemplate": "/api/chat/{everything}", "DownstreamScheme": "https", "DownstreamHostAndPorts": [ { "Host": "localhost", "Port": 44367 //Make sure the port same with your Administration Service } ], "UpstreamPathTemplate": "/api/chat/{everything}", "UpstreamHttpMethod": [ "Put", "Delete", "Get", "Post" ] },

Run the project

Now, it should be working for you:

I flowed the guide setp by step there still has a error when search users is there something missing in the "Configure database tables"?

Hi,

Because the project you provided can't build, I made an example for you.

You are trying to add chat to a QaService, it needs more configuration:

You can check the example my shared, in this example, I added Chat to ProductService

Add Volo.Abp.Identity.Pro.HttpApi.Client and IdentityService.Application.Contracts to HttpApi.Host project

Configure RemoteServices

    "RemoteServices": {
        "AbpIdentity": {
          "BaseUrl": "https://localhost:44325/",
          "UseCurrentAccessToken": "false"
        }
      },
      "IdentityClients": {
        "Default": {
          "GrantType": "client_credentials",
          "ClientId": "Qa_AdministrationService",
          "ClientSecret": "1q2w3e*",
          "Authority": "https://localhost:44322",
          "Scope": "IdentityService"
        }
      },
   ```
