|
||||
|
||||
## 🛠️ Technical Implementation Details
|
||||
|
||||
### gRPC HTTP Annotations
|
||||
تمام سرویسها با HTTP annotations تعریف شدهاند:
|
||||
- Admin endpoints: `/ServiceName` pattern
|
||||
- Customer endpoints: `/Customer/Action` pattern
|
||||
|
||||
### Clean Architecture Structure
|
||||
```
|
||||
CMSMicroservice.Domain/ # Core business entities
|
||||
CMSMicroservice.Application/ # Business logic & CQRS
|
||||
CMSMicroservice.Infrastructure/ # Data access & external services
|
||||
CMSMicroservice.WebApi/ # gRPC services & controllers
|
||||
CMSMicroservice.Protobuf/ # Protocol buffer definitions
|
||||
```
|
||||
|
||||
### Swagger Integration
|
||||
- Multiple Swagger documents: cms, admin, customer, unified
|
||||
- gRPC HTTP transcoding enabled
|
||||
- Custom CSS styling applied
|
||||
- Conflict resolution implemented
|
||||
|
||||
## 🔧 Issues Resolved
|
||||
|
||||
### 1. Swagger Conflict Resolution
|
||||
**Problem**:
|
||||
```
|
||||
Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorException:
|
||||
Conflicting method/path combination "GET GetUserCart"
|
||||
```
|
||||
|
||||
**Root Cause**:
|
||||
- دو method با operation ID یکسان: `GetUserCart` و `GetUserCartForCustomer`
|
||||
- Swagger از method name برای operation ID استفاده میکند
|
||||
|
||||
**Solutions Attempted**:
|
||||
1. ❌ `CustomOperationIds` - ineffective
|
||||
2. ❌ `ResolveConflictingActions` - incomplete resolution
|
||||
3. ✅ **Method Renaming** - successful
|
||||
|
||||
**Final Solution**:
|
||||
```protobuf
|
||||
// Before (conflicting):
|
||||
rpc GetUserCartForCustomer(GetUserCartForCustomerRequest) returns (GetUserCartForCustomerResponse)
|
||||
|
||||
// After (resolved):
|
||||
rpc GetCustomerCart(GetUserCartForCustomerRequest) returns (GetUserCartForCustomerResponse)
|
||||
```
|
||||
|
||||
### 2. Application Layer Dependencies
|
||||
**Problem**: Build errors در Application layer
|
||||
**Solution**: پاکسازی dependencies و rebuild پروژه
|
||||
|
||||

## 🎯 Next Steps
|
||||
1. **Service Integration Testing** - تست عملکرد سرویسهای migrate شده
|
||||
2. **Business Logic Implementation** - پیادهسازی منطق کسبوکار واقعی
|
||||
3. **Database Integration** - اتصال به لایه دیتا
|
||||
4. **Continue Migration** - ادامه migration سایر سرویسها
|
||||
|
||||
## 🏗️ Technical Architecture
|
||||
|
||||
### gRPC Service Pattern
|
||||
```csharp
|
||||
public class ServiceName : ServiceContract.ServiceContractBase
|
||||
{
|
||||
private readonly IDispatchRequestToCQRS _dispatcher;
|
||||
|
||||
// Customer Methods Section
|
||||
#region Customer Methods
|
||||
public override async Task<Response> CustomerMethod(Request request, ServerCallContext context)
|
||||
{
|
||||
// Implementation
|
||||
}
|
||||
#endregion
|
||||
|
||||
// Admin Methods Section
|
||||
#region Admin Methods
|
||||
public override async Task<Response> AdminMethod(Request request, ServerCallContext context)
|
||||
{
|
||||
// Implementation
|
||||
}
|
||||
#endregion
|
||||
}
|
||||
```
|
||||
|
||||
### Proto File Structure
|
||||
```protobuf
|
||||
syntax = "proto3";
|
||||
import "google/api/annotations.proto";
|
||||
|
||||
service ServiceContract {
|
||||
// ============= Admin Methods =============
|
||||
rpc AdminMethod(Request) returns (Response) {
|
||||
option (google.api.http) = {
|
||||
post: "/AdminEndpoint"
|
||||
body: "*"
|
||||
};
|
||||
};
|
||||
|
||||
// ============= Customer Methods =============
|
||||
rpc CustomerMethod(Request) returns (Response) {
|
||||
option (google.api.http) = {
|
||||
get: "/Customer/Endpoint"
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
## 📈 Performance & Quality
|
||||
- ✅ All services compile successfully
|
||||
- ✅ Swagger documentation accessible
|
||||
- ✅ gRPC HTTP transcoding working
|
||||
- ✅ Clean separation of Admin/Customer concerns
|
||||
- ✅ Consistent naming conventions applied
