Overview

Package httpsec defines is the HTTP instrumentation API and contract for AppSec. It defines an abstract representation of HTTP handlers, along with helper functions to wrap (aka. instrument) standard net/http handlers. HTTP integrations must use this package to enable AppSec features for HTTP, which listens to this package's operation events.

Functions

func ExecuteSDKBodyOperation

func ExecuteSDKBodyOperation(parent dyngo.Operation, args types.SDKBodyOperationArgs) error

ExecuteSDKBodyOperation starts and finishes the SDK Body operation by emitting a dyngo start and finish events An error is returned if the body associated to that operation must be blocked

func MakeHandlerOperationArgs

func MakeHandlerOperationArgs(r *http.Request, clientIP netip.Addr, pathParams map[string]string) types.HandlerOperationArgs

MakeHandlerOperationArgs creates the HandlerOperationArgs value.

func MakeHandlerOperationRes

func MakeHandlerOperationRes(w http.ResponseWriter) types.HandlerOperationRes

MakeHandlerOperationRes creates the HandlerOperationRes value.

func MonitorParsedBody

func MonitorParsedBody(ctx context.Context, body any) error

MonitorParsedBody starts and finishes the SDK body operation. This function should not be called when AppSec is disabled in order to get preciser error logs.

func StartOperation

func StartOperation(ctx context.Context, args types.HandlerOperationArgs, setup ...func(*types.Operation)) (context.Context, *types.Operation)

StartOperation starts an HTTP handler operation, along with the given context and arguments and emits a start event up in the operation stack. The operation is linked to the global root operation since an HTTP operation is always expected to be first in the operation stack.

func WrapHandler

func WrapHandler(handler http.Handler, span ddtrace.Span, pathParams map[string]string, opts *Config) http.Handler

WrapHandler wraps the given HTTP handler with the abstract HTTP operation defined by HandlerOperationArgs and HandlerOperationRes. The onBlock params are used to cleanup the context when needed. It is a specific patch meant for Gin, for which we must abort the context since it uses a queue of handlers and it's the only way to make sure other queued handlers don't get executed. TODO: this patch must be removed/improved when we rework our actions/operations system

Types

	// OnBlock is a list of callbacks to be invoked when a block decision is made.

	// purposes (the value may be provided by copy). This allows customers to
	// apply synchronization if they allow http.ResponseWriter objects to be
	// accessed by multiple goroutines.
	ResponseHeaderCopier func(http.ResponseWriter) http.Header
