测试烧瓶应用程序时出现BadRequestKeyError

POST 请求如下所示:

import pytest

def test_signup(client, app):
    assert client.get("/auth/signup").status_code == 200

    response = client.post("/auth/signup", data={"email": "user@example.com", "password": "12345"})

    assert "http://localhost/auth/signin" == response.headers["Location"]

蓝图路线中的代码:

@bp.route('/signup', methods=['GET', 'POST'])
def signup():
    form = SignupForm()
    if form.validate_on_submit():
        user = User(email=form.email.data)
        user.set_password(form.password.data)
        db.session.add(user)
        db.session.commit()
        flash('Congratulations, you are now a registered user!')
        return redirect(url_for('auth.signin'))

    return render_template('auth/signup.html', title='Sign up', form=form)

创建为:

def create_app(config_class=Config):
    app = Flask(__name__)
    app.config.from_object(config_class)

    db.init_app(app)

    # Other code
    from app.auth import bp as auth_bp
    app.register_blueprint(auth_bp, url_prefix='/auth')

    return app

代码在浏览器中工作,但在测试中出现以下错误:

失败的测试/test\u auth.py::test\u signup-werkzeug.exceptions.BadRequestKeyError:400错误请求:浏览器(或代理)发送了此服务器无法理解的请求

我想 form.validate_on_submit() 退货 False ,但我不明白为什么。
