Class ScalarValueValidationMiddleware

Namespace

Trellis.Asp

Assembly

Trellis.Asp.dll

Middleware that creates a validation error collection scope for each request. This enables ValidatingJsonConverter to collect validation errors across the entire request deserialization process.

Examples

Registering the middleware in Program.cs:

app.UseScalarValueValidation();
// ... other middleware
app.MapControllers();

Remarks

This middleware should be registered early in the pipeline, before any middleware that might deserialize JSON request bodies.

For each request:

• Creates a new validation error collection scope
• Allows the request to proceed through the pipeline
• Catches BadHttpRequestException for IScalarValue<TSelf, TPrimitive> parameter binding failures and returns validation problem
• Cleans up the scope when the request completes

Constructors

ScalarValueValidationMiddleware(RequestDelegate)

Creates a new instance of ScalarValueValidationMiddleware.

public ScalarValueValidationMiddleware(RequestDelegate next)

Parameters

next RequestDelegate

The next middleware in the pipeline.

Methods

InvokeAsync(HttpContext)

Invokes the middleware, wrapping the request in a validation scope.

public Task InvokeAsync(HttpContext context)

Parameters

context HttpContext

The HTTP context for the request.

Returns

Task
