HttpRequest and HttpResponse System Entities
Introduction
HttpRequest is a system entity that represents a request to a server. HttpResponse represents the response from the server. Use these entities when publishing or consuming REST services.
HttpRequest
The HttpRequest entity has the following attributes:
| Attribute | Type | Default Value | Description |
|---|---|---|---|
HttpVersion (Inherited from HttpMessage) |
String | HTTP/1.1 | The protocol version. You can almost always ignore this value. |
Uri |
String | empty | The full URI for the incoming request, including query parameters. |
Content (inherited from HttpMessage) |
String | empty | The body of the request. |
You can retrieve the request headers via the HttpHeaders association.
HttpResponse
The HttpResponse entity has the following attributes:
| Attribute | Type | Default Value | Description |
|---|---|---|---|
HttpVersion (inherited from HttpMessage) |
String | HTTP/1.1 | The protocol version. You can almost always ignore this value. |
StatusCode |
Integer | 200 | The HTTP status code returned by the server. |
