我々は、ファイアウォールのログインとサインアップ機能を持つPythonとGUIアプリケーションを作成します.

サインアップ→


サインイン--

ステップ1 ->最初のステップはFireBaseプロジェクトを作成することです.
https://console.firebase.comでFireBaseコンソールに移動します.見つからない場合は、新しいFireBase Webプロジェクトを作成します.


ステップ2 -> 2番目のステップは、firebaseという名前の新しいPythonファイルを作成することです.PYまたはメイン.py ( nameは問題ではありません).次にPIPを使用します.
pip install pyrebase
ステップ3 -> 3番目の手順はpyp 5をpip install pyqt 5 ( Windows用)を使ってインストールすることです.
pip install PyQt5
pip install pyqt5-tools

from PyQt5 import QtCore, QtGui, QtWidgets
import sys
import pyrebase
ステップ4 -> PyRebaseでfirebaseを初期化する
config = {
    "apiKey": "AIzaSyDZw2TKNMPLkFBI7qPzklTGbd8bYkIyfUc",
    "authDomain": "py-firebase-f97fc.firebaseapp.com",
    "databaseURL": "https://py-firebase-f97fc-default-rtdb.firebaseio.com",
    "projectId": "py-firebase-f97fc",
    "storageBucket": "py-firebase-f97fc.appspot.com",
    "messagingSenderId": "130186938120",
    "appId": "1:130186938120:web:d8b87ef2a01af62dbf4ebd",
    "measurementId": "G-9R811DMZEL",
    "serviceAccount":".\py-firebase-f97fc-firebase-adminsdk-7w4qw-52ae79b7e5.json"
    }

firebase = pyrebase.initialize_app(config)
ステップ5 ->ユーザが存在するかどうかを確認する
try:
    IsUser=user['userId']
except:
       IsUser = None
ステップ6 -->ステップ6でauthを定義し始める
auth = firebase.auth()
ステップ7 ->現在、クラスを作成する時間とユーザが存在するかどうかをチェックする
class Ui_Dialog(object):
# if IsUser == None :
ステップ8 --> GUIを定義します.私はQt 5のデザイナーとそれを作成して、あなた自身を作成したり、練習のために私のコードを使用します.

def setupUi(self, Dialog):
        Dialog.setObjectName("Python with Firebase")
        Dialog.resize(447, 621)
        self.gridLayout = QtWidgets.QGridLayout(Dialog)
        self.gridLayout.setObjectName("gridLayout")
        self.verticalFrame = QtWidgets.QFrame(Dialog)
        self.verticalFrame.setMinimumSize(QtCore.QSize(429, 300))
        self.verticalFrame.setObjectName("verticalFrame")
        self.verticalLayout = QtWidgets.QVBoxLayout(self.verticalFrame)
        self.verticalLayout.setObjectName("verticalLayout")

        self.lineEdit = QtWidgets.QLineEdit(self.verticalFrame)
        self.lineEdit.setMinimumSize(QtCore.QSize(300, 40))
        self.lineEdit.setMaximumSize(QtCore.QSize(500, 40))
        self.lineEdit.setStyleSheet("border-radius:2px;\n"
        "padding:2px;\n"
        "content:'Email';\n"
"border:1px solid #262626;")
        self.lineEdit.setObjectName("lineEdit")
        self.verticalLayout.addWidget(self.lineEdit, 0, QtCore.Qt.AlignHCenter)
        self.lineEdit_2 = QtWidgets.QLineEdit(self.verticalFrame)
        self.lineEdit_2.setMinimumSize(QtCore.QSize(300, 40))
        self.lineEdit_2.setMaximumSize(QtCore.QSize(300, 40))
        self.lineEdit_2.setStyleSheet("\n"
"border-radius:2px;\n"
"padding:2px;\n"
"content:'Password';\n"
"border:1px solid #262626;")
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.verticalLayout.addWidget(self.lineEdit_2, 0, QtCore.Qt.AlignHCenter)
        self.toolButton_2 = QtWidgets.QToolButton(self.verticalFrame)
        self.toolButton_2.setMinimumSize(QtCore.QSize(300, 40))
        self.toolButton_2.setMaximumSize(QtCore.QSize(300, 40))
        self.toolButton_2.setStyleSheet("background:#ccc;\n"
"border-radius:2px;\n"
"\n"
"")
        self.toolButton_2.setObjectName("toolButton_2")
        self.verticalLayout.addWidget(self.toolButton_2, 0, QtCore.Qt.AlignHCenter)
        self.toolButton = QtWidgets.QToolButton(self.verticalFrame)
        self.toolButton.setMinimumSize(QtCore.QSize(300, 40))
        self.toolButton.setMaximumSize(QtCore.QSize(300, 40))
        self.toolButton.setStyleSheet("background-color:#f23041;\n"
"border-radius:5px;\n"
"color:#fff;\n"
"")

        self.toolButton.setObjectName("toolButton")
        self.verticalLayout.addWidget(self.toolButton, 0, QtCore.Qt.AlignHCenter)
        self.gridLayout.addWidget(self.verticalFrame, 0, 1, 1, 1)
        self.toolButton_2.clicked.connect(self.signin)
        self.toolButton.clicked.connect(self.signup)
        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.toolButton_2.setText(_translate("Dialog", "SignIn"))


        self.toolButton.setText(_translate("Dialog", "SignUp"))
次の手順では、OnClick関数を定義します
self.toolButton_2.clicked.connect(self.signin)
self.toolButton.clicked.connect(self.signup)
ステップ9 -- onclick関数
def signup(self):
        email = self.lineEdit.text()
        password = self.lineEdit.text()
        user = auth.create_user_with_email_and_password(email, password)
        user = auth.refresh(user['refreshToken'])
        print('Sucessfully accounted in: {0}'.format(user['userId']))
        IsUser=user['userId']

    def signin(self):
        email = self.lineEdit.text()
        password = self.lineEdit.text()
        user = auth.sign_in_with_email_and_password(email, password) 
        user = auth.refresh(user['refreshToken'])
        print('Sucessfully logged in: {0}'.format(user['userId']))
        IsUser=user['userId']
ここでは、私たちは、あなたがコンソールに印刷されるメッセージでfirebaseログインとsignup機能を宣言しました、そして、タスクが成功するならば、あなたはそれを見ることができます.

Step 10 ->最後のステップでif if文でウィンドウを開始させる
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)

    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_Dialog()

    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())
アプリを実行します.
