如何解决测试 FastAPI OAuth2passwordrequestForm Got 400 状态码？

开发过程中遇到测试 FastAPI OAuth2passwordrequestForm Got 400 状态码的问题如何解决？下面主要结合日常开发的经验，给出你关于测试 FastAPI OAuth2passwordrequestForm Got 400 状态码的解决方法建议，希望对你解决测试 FastAPI OAuth2passwordrequestForm Got 400 状态码有所启发或帮助；

我正在尝试测试将检查用户凭据的路由。

这是我的单元测试

@pytest.mark.parametrize(
    "payload,status_code",[
        [{"username": "john","password": "secret"},status.http_200_OK],[{"username": "john"},status.http_401_UNAUTHORIZED],[{"password": "secret"},[{},status.http_401_UNAUTHORIZED]
    ]
)
def test_user_credentials(test_app: TESTClIEnt,monkeypatch,payload,status_code):
    async def mock_check_credentials(credentials:User):
        if "email" in payload and "password" in payload:
            return True
        return false

    monkeypatch.setattr(user_repository,"check_credentials",mock_check_credentials)
    response = test_app.post("/users/credentials",data=Json.dumps(payload),headers={"content-type": "multipart/form-data"})
    assert response.status_code == status_code

这是我的路线

@router.post("/credentials",status_code=status.http_200_OK)
async def check_user_credentials(request: OAuth2passwordrequestForm = Depends()):
    valID_credentials = await user_repository.check_credentials(request)
    if not valID_credentials:
        raise httpException(
            status_code=status.http_401_UNAUTHORIZED,detail="Incorrect username or password",headers={"WWW-Authenticate": "Bearer"},)
    return True

这是我的存储库方法：

async def check_credentials(user: OAuth2passwordrequestForm):
    query = Users.SELEct().where(Users.c.email == user.userName)
    exists = await database.fetch_one(query=query)
    if not exists:
        return false
    password_ok = hashing.verify(exists.get("password"),user.password)
    if not password_ok:
        return false
    return True

但是我得到的状态代码是 400，我期望第一次测试是 200，其他测试是 401。

test_app = <starlette.TESTClIEnt.TESTClIEnt object at 0x7f75199fb9a0>,monkeypatch = <_pytest.monkeypatch.MonkeyPatch object at 0x7f7519c369a0>,payload = {},status_code = 401

    @pytest.mark.parametrize(
        "payload,[
            [{"username": "john",status.http_401_UNAUTHORIZED]
        ]
    )
    def test_user_credentials(test_app: TESTClIEnt,status_code):
        async def mock_check_credentials(credentials:User):
            if "email" in payload and "password" in payload:
                return True
            return false
    
        monkeypatch.setattr(user_repository,mock_check_credentials)
        response = test_app.post("/users/credentials",headers={"content-type": "multipart/form-data"})
>       assert response.status_code == status_code
E       assert 400 == 401
E        +  where 400 = <Response @R_197_11240@0]>.status_code

在手动测试中（使用 Swagger UI），这条路线完美运行。

我无法面对我在这里缺少的东西

编辑：我找到了 this thread，但它没有帮助我：我的requirement.txt 中有python-multipart>=0.0.5 并且我已经安装了它
