If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure { #an-example-file-structure }

Let's say you have a file structure like this:

```
.

  }

  public void test() throws Exception {
    assertTrue(handler.getStoredLogRecords().isEmpty());
    ExampleClassUnderTest.foo();
    LogRecord record = handler.getStoredLogRecords().get(0);
    assertEquals(Level.INFO, record.getLevel());
    assertEquals("message", record.getMessage());
    assertSame(EXCEPTION, record.getThrown());
  }

  public void testConcurrentModification() throws Exception {

                connect0(); // treeConnect is good enough
            } else {
                final Info info = queryPath(getUncPath0(), Trans2QueryPathInformationResponse.SMB_QUERY_FILE_BASIC_INFO);
                attributes = info.getAttributes();
                createTime = info.getCreateTime();
                lastModified = info.getLastWriteTime();
            }

            t.setDaemon(true);
            return t;
        });

        // Start health check task
        if (healthCheckInterval > 0) {
            startHealthCheckTask();
        }

        log.info("MultiChannelManager initialized with maxChannels={}, strategy={}, healthCheckInterval={}ms", maxChannels,
                loadBalancingStrategy, healthCheckInterval);
    }

    /**

/// info | Información

Esto requiere instalar `orjson`, por ejemplo, con `pip install orjson`.

///

### `UJSONResponse`

Un response JSON alternativo usando <a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>.

/// info | Información

                                    <%-- Message --%>
                                <div>
                                    <la:info id="msg" message="true">
                                        <div class="alert alert-info">${msg}</div>
                                    </la:info>
                                    <la:errors/>
                                </div>
                                    <%-- List --%>

# Dados do formulário

Quando você precisar receber campos de formulário ao invés de JSON, você pode usar `Form`.

/// info | Informação

Para usar formulários, primeiro instale <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Lembre-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo e então instalar a dependência, por exemplo:

```console

					</button>
					<button type="submit" class="btn btn-primary">
						<em class="fa fa-search">
						<la:message key="labels.search" />
					</button>
					<la:link href="/search/advance" styleClass="btn btn-info">
						<em class="fa fa-cog">
						<la:message key="labels.advance" />
					</la:link>
				</div>
			</div>
		</div>
		<main class="container">
			<div class="row">

    @Test
    public void test_Get() {
        Curl.get("https://www.codelibs.org/").execute(response -> {
            final String content = response.getContentAsString();
            logger.info(content);
            assertTrue(content.length() > 0);
        }, e -> {
            logger.log(Level.SEVERE, "error", e);
            fail();
        });
    }
