**FastAPI** 直接提供了相同的 `WebSocket`，只是为了方便开发人员。但它直接来自 Starlette。

///

## 等待消息并发送消息

在您的 WebSocket 路由中，您可以使用 `await` 等待消息并发送消息。

{* ../../docs_src/websockets/tutorial001.py hl[48:52] *}

您可以接收和发送二进制、文本和 JSON 数据。

## 尝试一下

如果您的文件名为 `main.py`，请使用以下命令运行应用程序：

```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)
```

For Go 1.24, it now defaults to multipathtcp="2", thus
enabled by default on listeners. Using multipathtcp="0" reverts to the
pre-Go 1.24 behavior.

Go 1.24 changed the behavior of `go test -json` to emit build errors as JSON
instead of text.
These new JSON events are distinguished by new `Action` values,
but can still cause problems with CI systems that aren't robust to these events.

## 메시지를 대기하고 전송하기

WebSocket 경로에서 메시지를 대기(`await`)하고 전송할 수 있습니다.

{* ../../docs_src/websockets/tutorial001.py hl[48:52] *}

여러분은 이진 데이터, 텍스트, JSON 데이터를 받을 수 있고 전송할 수 있습니다.

## 시도해보기

파일 이름이 `main.py`라고 가정하고 응용 프로그램을 실행합니다:

<div class="termy">

```console
$ fastapi dev main.py

import requests

app = Flask(__name__)
@app.route('/', methods=['POST'])
def get_webhook():
	if request.method == 'POST':
		# obtain the request event from the 'POST' call
		event = request.json

		object_context = event["getObjectContext"]

		# Get the presigned URL to fetch the requested
		# original object from MinIO
		s3_url = object_context["inputS3Url"]

createPolicy($name, $filename) createPolicy () { NAME=$1 FILENAME=$2 # Create the name if it does not exist echo "Checking policy: $NAME (in /config/$FILENAME.json)" if ! checkPolicyExists $NAME ; then echo "Creating policy '$NAME'" else echo "Policy '$NAME' already exists." fi ${MC} admin policy create myminio $NAME /config/$FILENAME.json } # Try connecting to MinIO instance {{- if .Values.tls.enabled }} scheme=https {{- else }} scheme=http {{- end }} connectToMinio $scheme {{ if .Values.policies...

# createPolicy($name, $filename) createPolicy () { NAME=$1 FILENAME=$2 # Create the name if it does not exist echo "Checking policy: $NAME (in /config/$FILENAME.json)" if ! checkPolicyExists $NAME ; then echo "Creating policy '$NAME'" else echo "Policy '$NAME' already exists." fi ${MC} admin policy add myminio $NAME /config/$FILENAME.json } # Try connecting to MinIO instance {{- if .Values.tls.enabled }} scheme=https {{- else }} scheme=http {{- end }} connectToMinio $scheme {{ if .Values.policies...

# createPolicy($name, $filename) createPolicy () { NAME=$1 FILENAME=$2 # Create the name if it does not exist echo "Checking policy: $NAME (in /config/$FILENAME.json)" if ! checkPolicyExists $NAME ; then echo "Creating policy '$NAME'" else echo "Policy '$NAME' already exists." fi ${MC} admin policy add myminio $NAME /config/$FILENAME.json } # Try connecting to MinIO instance {{- if .Values.tls.enabled }} scheme=https {{- else }} scheme=http {{- end }} connectToMinio $scheme {{ if .Values.policies...

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["cookie", "santa_tracker"],
            "msg": "Extra inputs are not permitted",
            "input": "good-list-please",

```

you would receive the multiple `q` *query parameters'* values (`foo` and `bar`) in a Python `list` inside your *path operation function*, in the *function parameter* `q`.

So, the response to that URL would be:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```
