烧瓶蓝图404

我在尝试访问Flask蓝图中定义的路线时得到404,但我不明白为什么。有没有人看到我做错了什么(我是Flask和Python的新手,所以它可能是基本的东西)?

我的蓝图(test.py):

from flask import Blueprint, jsonify, request
from werkzeug.local import LocalProxy

test_blueprint = Blueprint(
    'test_blueprint', __name__, url_prefix='/test')


@test_blueprint.route('/test', methods=['GET'])
def get_all_tests():

    return jsonify([{
        "id": "1",
        "name": "Foo"
    }, {
        "id": "2",
        "name": "Bar"
    }, {
        "id": "3",
        "name": "Baz"
    }]), 200

我的app.py

from test import test_blueprint

from flask import abort, Flask
from os import environ


def create_app():

    app = Flask(__name__)

    app.config.from_object('config.settings')
    app.template_folder = app.config.get('TEMPLATE_FOLDER', 'templates')
    app.url_map.strict_slashes = False

    app.register_blueprint(test_blueprint)

    return app

点击http://127.0.0.1:5000/test的结果是:

(venv) mymachine:api myusername$ python run.py
 * Restarting with stat
Starting server at 127.0.0.1 listening on port 5000 in DEBUG mode
 * Debugger is active!
 * Debugger PIN: 123-456-789
127.0.0.1 - - [2018-06-03 17:02:56] "GET /test HTTP/1.1" 404 342 0.012197

app.pytest.py位于同一目录中,即fyi。

额外信息: 既然你可以看到我开始使用一个名为run.py的文件,那么就是那个文件,为了完整性:

from flask_failsafe import failsafe
from gevent import monkey
from gevent.pywsgi import WSGIServer
from werkzeug.debug import DebuggedApplication
from werkzeug.serving import run_with_reloader

@failsafe
def failsafe_app():
    from app import create_app
    return create_app()


app = failsafe_app()


@run_with_reloader
def run():

    app.debug = app.config['DEBUG']

    print('Starting server at %s listening on port %s %s' %
          (app.config['HOST'], app.config['PORT'], 'in DEBUG mode'
           if app.config['DEBUG'] else ''))

    if app.config['DEBUG']:
        http_server = WSGIServer((app.config['HOST'], app.config['PORT']),
                                 DebuggedApplication(app))
    else:
        if app.config['REQUEST_LOGGING']:
            http_server = WSGIServer((app.config['HOST'], app.config['PORT']),
                                     app)
        else:
            http_server = WSGIServer(
                (app.config['HOST'], app.config['PORT']), app, log=None)

    http_server.serve_forever()

当您使用url_prefix定义蓝图时,此蓝图的每个规则都会将此前缀与给定路径连接起来

在您的示例中,网址应为http://127.0.0.1:5000/test/test,以便访问视图get_all_tests

答案 1 :(得分:0)

您的端口号位于网址中的错误位置。

应为http://127.0.0.1:5000/test

如你所知,你正在点击标准端口80,寻找网址/test:5000
