在逻辑代码的处理添加数据包的请求，返回数据包的判断，就可以完整实现登录检测的一个界面化工具了
一、准备好ui的加载
老演员来了
python
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import *
class MyWindow(QWidget):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.ui = uic.loadUi("./my_win.ui")
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MyWindow()
w.ui.show() # 展示窗口
sys.exit(app.exec_())二、获取对应的触发事件
如图所示
此处：self.ui为顶层，然后下面为控件
python
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import *
class MyWindow(QWidget):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.ui = uic.loadUi("./my_win.ui")
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 与布局中控件相对应
# 获取对应触发事件
user_name = self.ui.lineEdit # 用户名
password = self.ui.lineEdit_2 # 获取密码
login_btn = self.ui.pushButton # 登录按钮
forget_btn = self.ui.pushButton_2 # 忘记密码
text_browser = self.ui.textBrowser # 文本显示区域
# -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MyWindow()
w.ui.show() # 展示窗口
sys.exit(app.exec_())三、触发事件绑定
1、绑定触发事件和对应的逻辑
2、写好逻辑处理函数
python
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import *
class MyWindow(QWidget):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.ui = uic.loadUi("./my_win.ui")
# 获取对应触发事件
user_name = self.ui.lineEdit # 用户名
password = self.ui.lineEdit_2 # 获取密码
login_btn = self.ui.pushButton # 登录按钮
forget_btn = self.ui.pushButton_2 # 忘记密码
text_browser = self.ui.textBrowser # 文本显示区域
# ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 新增如下
# 绑定登陆事件的逻辑
login_btn.clicked.connect(self.login)
def login(self):
# 登录逻辑
print("正在登录中")
# ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MyWindow()
w.ui.show() # 展示窗口
sys.exit(app.exec_())
三、输入内容的调用
获取到输入框内内容，并在登录逻辑中调用
（其实能在登录逻辑调用，就可以通过逻辑代码进行检测账号密码是否正确了）
python
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import *
class MyWindow(QWidget):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.ui = uic.loadUi("./my_win.ui")
# 获取对应触发事件
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 获取到用户输入
self.user_name = self.ui.lineEdit # 用户名
self.password = self.ui.lineEdit_2 # 获取密码
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
login_btn = self.ui.pushButton # 登录按钮
forget_btn = self.ui.pushButton_2 # 忘记密码
text_browser = self.ui.textBrowser # 文本显示区域
# 绑定登陆事件的逻辑
login_btn.clicked.connect(self.login)
def login(self):
# 登录逻辑
print("正在登录中")
#------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 在其他部分调用（并转换格式）
print(self.user_name.text())
print(self.password.text())
#------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MyWindow()
w.ui.show() # 展示窗口
sys.exit(app.exec_())
三、完善登录逻辑
1、完善相关数据的获取
2、完善登录的逻辑代码
python
import sys
from PyQt5 import uic
from PyQt5.QtWidgets import *
class MyWindow(QWidget):
def __init__(self):
super().__init__()
self.init_ui()
def init_ui(self):
self.ui = uic.loadUi("./my_win.ui")
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 完善相关数据的获取
# 获取对应触发事件
self.user_name = self.ui.lineEdit # 用户名
self.password = self.ui.lineEdit_2 # 获取密码
self.login_btn = self.ui.pushButton # 登录按钮
self.forget_btn = self.ui.pushButton_2 # 忘记密码
self.text_browser = self.ui.textBrowser # 文本显示区域
#
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 绑定登陆事件的逻辑
self.login_btn.clicked.connect(self.login)
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
# 完善登录逻辑
def login(self):
# 登录逻辑
uname = self.user_name.text()
pw = self.password.text()
if uname == "admin" and pw == "123456":
self.text_browser.setText("欢迎%s回来" % uname)
self.text_browser.repaint()
else:
self.text_browser.setText("%s的用户名或密码错误" % uname)
self.text_browser.repaint()
#
# ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MyWindow()
w.ui.show() # 展示窗口
sys.exit(app.exec_())正确登录
错误登录
