## Benutzerdefinierte Header hinzufügen { #add-custom-headers }

Es gibt Situationen, in denen es nützlich ist, dem HTTP-Error benutzerdefinierte Header hinzuzufügen. Zum Beispiel in einigen Sicherheitsszenarien.

Sie werden es wahrscheinlich nicht direkt in Ihrem Code verwenden müssen.

Aber falls Sie es für ein fortgeschrittenes Szenario benötigen, können Sie benutzerdefinierte Header hinzufügen:

@app.get("/items/{item_id}")
async def read_item(item_id: str):
    if item_id not in items:
        raise HTTPException(
            status_code=404,
            detail="Item not found",
            headers={"X-Error": "Some custom header"},
        )
    return {"item": items[item_id]}


@app.get("/http-no-body-statuscode-exception")
async def no_body_status_code_exception():
    raise HTTPException(status_code=204)

        }
    }

    @Nested
    @DisplayName("Execution")
    class ExecutionTests {

        @Test
        @DisplayName("should log appropriate header message")
        void shouldLogAppropriateHeaderMessage() throws Exception {
            UpgradeContext context = createMockContext();

            // Create a temporary directory with a POM file for the test

		contentType := r.Header.Get("Content-Type")
		if contentType == "application/json" {
			w.Header().Set("Content-Type", "application/json")
			jsonEncoder := json.NewEncoder(w)
			jsonEncoder.Encode(metrics)
			return
		}

		// If not JSON, return plain text. We format it as a markdown table for
		// readability.
		w.Header().Set("Content-Type", "text/plain")
		var b strings.Builder

        return CONTEXT_NAME_BYTES;
    }

        return new NoOpProcessor();
