微博 相册 爬虫 软件

文章目录

之前写过一款python3GUI–微博图片爬取工具V1.5（附源码）
，是基于python自带的GUI开发包tkinter，实现了对指定用户文章内图片的爬取，本次使用PyQt5，遵循UI界面与爬虫逻辑分离开来，实现思路大体相同，只不过tkinter与QT组件方法有所差别，走起~

一．准备工作

本程序是基于PyQt5的，需要额外安装一下，这里不多说。
UI界面的设计基于QT设计师，用它设计UI很方便。
关于以上模块、工具的安装可以参考PyCharm安装PyQt5及其工具（Qt Designer、PyUIC、PyRcc）详细教程

二．预览

1.启动

怎么样，是不是熟悉的感觉
请添加图片描述

2.搜索

用户搜索会调用两个API进行检索，将搜索到的相关用户去重后，展示在组合框中。
请添加图片描述

3.开始爬取

选取完图片保存路径，点击开始爬取，程序就开始工作了，爬取状态会在表格中实时显示。
请添加图片描述

4.结果

请添加图片描述
仅拿一张图片作为展示。

三．设计流程

1.整体流程

在这里插入图片描述

2.UI设计(草图)

在这里插入图片描述

3.UI设计(QT设计师)

使用QT设计师，设计UI界面，使用QMainWindow作为模板，去除了工具栏与状态栏，保留了菜单栏，使用QLabel、QLineEdit、QPushButton、QCombobox、QTableWidget、QGroupBox等组件。整体垂直布局，局部水平布局。
请添加图片描述

四．源代码

1.Wei_Bo_pics_Crawl.py（主程序）

#-*-coding:utf-8-*-

import sys
from threading import Thread
from PyQt5.Qt import QMainWindow,QMessageBox,QFileDialog,QMenu,QTableWidgetItem,QApplication
from PyQt5.QtCore import pyqtSignal, pyqtSlot, QSize
from PyQt5.QtGui import QPixmap
from Weibo_Crawl_Engine import Weibo_Pic_Spider
from WeiBo_Pics_Crawl import Ui_MainWindow
"""

图片可以爬取了，但是图片爬完的tablewidget显示还有问题    **已解决**
保存图片路径有问题，还要加上用户名子目录名称  **已实现**
1.加载网络图片
2.自定义信号槽，保证tablewidget在UI线程中

3.Weibo_Crawl_Engine.py（爬虫）

由于篇幅，Weibo_Crawl_Engine.py的代码详见：

python3GUI–微博图片爬取工具V1.5（附源码）

五．总结

本次使用PyQt5撰写一款微博图片爬取工具，在爬取过程中遇到了两个难点问题：
1.Qlabel显示网络图片
此问题解决参考了pyqt5加载网路图片，不本地下载。
2.自定义信号槽，保证tablewidget在UI线程中
此问题解决参考了PyQt 5信号与槽的几种高级玩法
感谢各位！程序打包好放在了百度云 密码：8888。思路、代码方面有什么不足欢迎各位大佬指正、批评！
