### 运行应用程序

您可以运行这个应用程序：

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然后在 `/docs` UI 中，您能够看到 **FastAPI** 会用这些**模型**来**记录** API，并且还会用它们来**序列化**和**验证**数据。

<div class="screenshot">

            CountDownLatch startLatch = new CountDownLatch(1);
            CountDownLatch holdLatch = new CountDownLatch(1);
            CountDownLatch completeLatch = new CountDownLatch(1);

            // Start a long-running operation
            Thread longRunningThread = new Thread(() -> {
                try {
                    cbWithTracking.executeWithCircuitBreaker(() -> {
                        try {

  return run_shell([python_bin_path, '-c', 'import sys; print(sys.version[0])'])


def setup_python(environ_cp):
  """Setup python related env variables."""
  # Get PYTHON_BIN_PATH, default is the current running python.
  default_python_bin_path = sys.executable
  ask_python_bin_path = ('Please specify the location of python. [Default is '
                         '{}]: ').format(default_python_bin_path)
  while True:

errors.invalid_str_is_included = {1} is invalid for {0}.
errors.blank_password = Password is required.
errors.invalid_confirm_password = Does not match a confirmation password.
errors.cannot_delete_doc_because_of_running = A crawler is running. You cannot delete documents.
errors.failed_to_delete_doc_in_admin = Failed to delete a document.
errors.failed_to_send_testmail=Failed to send a test mail.

		* Restored the ability of kubectl running inside a pod to consume resource files specifying a different namespace than the one the pod is running in. ([#44862](https://github.com/kubernetes/kubernetes/pull/44862), [@liggitt](https://github.com/liggitt))

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## Es testen { #check-it }

这是因为 **OAuth2** 使用**表单数据**发送 `username` 与 `password`。

///

用下面的命令运行该示例：

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>
