### 获取当前用户数据

使用 `/users/me` 路径的 `GET` 操作。

可以提取如下当前用户数据：

```JSON
{
  "username": "johndoe",

from base64 import b64encode

from fastapi.testclient import TestClient

from docs_src.security.tutorial006_an import app

client = TestClient(app)


def test_security_http_basic():
    response = client.get("/users/me", auth=("john", "secret"))
    assert response.status_code == 200, response.text
    assert response.json() == {"username": "john", "password": "secret"}


def test_security_http_basic_no_credentials():

from dirty_equals import IsDict, IsOneOf
from fastapi.testclient import TestClient

from docs_src.security.tutorial005 import (
    app,
    create_access_token,
    fake_users_db,
    get_password_hash,
    verify_password,
)

client = TestClient(app)


def get_access_token(username="johndoe", password="secret", scope=None):
    data = {"username": username, "password": password}
    if scope:
        data["scope"] = scope
