### Die Responses betrachten

Wenn Sie nun zur URL mit dem Port für Uvicorn gehen: <a href="http://127.0.0.1:8000/app" class="external-link" target="_blank">http://127.0.0.1:8000/app</a>, sehen Sie die normale Response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

#### OpenAPIの目的

		if rec.Code != testCase.expectedRespStatus {
			t.Errorf("Test %d: %s: Expected the response status to be `%d`, but instead found `%d`", i+1, instanceType, testCase.expectedRespStatus, rec.Code)

		// Verify response the V2 signed HTTP request.
		// initialize HTTP NewRecorder, this records any mutations to response writer inside the handler.
		recV2 := httptest.NewRecorder()

      val code = response.code
      if (code != HTTP_TEMP_REDIRECT && code != HTTP_PERM_REDIRECT) return response
      val method = response.request.method
      if (method == "GET" || method == "HEAD") return response
      val location = response.header("Location") ?: return response

        .header("LegacyRedirectInterceptor-Location", location)

It is designed to have functions that receive two parameters, one "request" and one "response". Then you "read" parts from the request, and "write" parts to the response. Because of this design, it is not possible to declare request parameters and bodies with standard Python type hints as function parameters.
