（pyqt5）弹窗-Token验证

前言

        为了保护自己的工作成果,控制在合理的范围内使用,设计一个用于Token验证的弹窗.

代码

class TokenDialog(QDialog):
    def __init__(self, parent=None, login_user=None, mac_addr=None, func=None):
        super(TokenDialog, self).__init__(parent)
        self.login_user = login_user
        self.mac_addr = mac_addr

        self.func = func
        self.init_ui(parent)
        self.setWindowTitle("TOKEN验证窗口")
        self.setWindowFlags(Qt.FramelessWindowHint)  # 设置窗口无边框
        self.setFixedSize(400, 200)

    def init_ui(self, parent):
        '''水平布局'''
        self.msg_res = QLabel("")

        hbox = QHBoxLayout()
        self.save_btn = QPushButton()
        self.save_btn.setText('验证')
        self.save_btn.clicked.connect(lambda: self.save_btn_click())

        self.cancel_btn = QPushButton()
        self.cancel_btn.setText('取消')
        self.cancel_btn.clicked.connect(self.cancel_btn_click)

        hbox.addWidget(self.save_btn)
        hbox.addWidget(self.cancel_btn)

        fbox = QFormLayout()

            self.pw_text.setText(token_v)

        vbox.addLayout(fbox)

        vbox.addLayout(hbox)
        self.setLayout(vbox)

        return {
            "user": self.email_text.text().strip(),
            "token": self.pw_text.text().strip()
        }

    def save_btn_click(self):
        ret_dict = self.get_val()
        if self.func and ret_dict["token"]:
            self.func(ret_dict["token"])

    def cancel_btn_click(self):
        self.close()


def get_add_dialog(parent=None, login_user=None, mac_addr=None, func=None):
    dialog = TokenDialog(parent, login_user, mac_addr, func)
    dialog.setFixedSize(400, 200)
    return dialog.exec()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    example = TokenDialog()
    example.show()
    sys.exit(app.exec_())
