用python和Beautiful Soup来做一个图片下载器（优化版）
前言
这是一个使用python和beautifulsoup4编写的图片下载程序，主要支持视觉中国网站，可以获取当前网址网页的图片列表，有3种图片下载方式，全部下载、单张下载以及任意张下载。
本例是在之前的一篇博文的基础上，进行了优化了，使界面看起来更整齐，增加了网页浏览。
实际窗口：
如上图，可以直接在“图片获取网址”处输入网址，然后点击获取列表按钮，也可以先在“网址”处输入网址，如视觉中国，可以在界面内的浏览器浏览网页，寻找需要的图片页面，网址会自动更新。
右侧是下载按钮，图片保存地址默认是桌面，也可以手动修改。
所以，本程序大致分为三部分，一是界面内网页浏览，使用Qwebengineview模块，一是网页数据获取和分析，使用requests和beautifulsoup4模块，一是图片下载，使用urllib模块。
以下分别说明：
一、界面网页浏览
在窗口界面内浏览网页，主要使用Qt的Qwebengineview模块，或者说部件。
通常情况下，创建一个实力即可：
self.webview=QWebEngineView(self)
但本例中为了实现网页浏览时，可以点击网页上的链接，实现窗口内跳转，于是重写了Qwebengineview的createwindow函数：
class MyWebEngineView(QWebEngineView):
"""此处重载了QWebEngineView,当点击网页内链接时，可以在本窗口内跳转"""
def createWindow(self,QWebEnginePage_WebWindowType):
page = MyWebEngineView(self)
page.urlChanged.connect(self.on_url_changed)
return page
def on_url_changed(self,url):
self.setUrl(url)
然后在主窗口界面调用上面的类实例：
self.webview=MyWebEngineView(self)
self.webview.setGeometry(20,120,480,600)
self.webview.setZoomFactor(0.4)
self.webview.loadFinished.connect(self.urlchange_f)
self.webview.urlChanged.connect(self.urlchange_f)
这样，当我们在窗口上打开一个网页时，就可以实现窗口内跳转了。
二、网页获取数据
首先是通过requests的get函数，获取给定网址的原始数据。
def get_url_text(self, url):
# 获取当前网址下的总体信息
url_info = requests.get(url)
url_info.encoding = url_info.apparent_encoding
url_text = url_info.text
return url_text
然后将获取的网页数据返回，网页原始数据大致如下：
数据来自视觉中国网页

def get_img_url_list(self, url):
# 对获取的网页信息进行处理，提取图片链接地址
url_text = self.get_url_text(url)
#print(url_text)
soup = BeautifulSoup(url_text, 'html.parser')
url_list = soup.find('div', class_='gallery_inner')
img_url_list = url_list.find_all('a')
# print(img_url_list)
lli = img_url_list[:(len(img_url_list) - 1)]
# print(len(lli))
img_num = str(len(lli))
self.lbl_imgnumber.setText('共找到: ' + img_num + ' 张图片')
#self.lbl_imgnumber.adjustSize()
self.te.clear()
# 对获取到的图片链接地址信息再次处理，将其分割并有序存入list表中。
for i, img_url_list_s in enumerate(lli):
# print(img_url_list_s)
li = img_url_list_s.find('img')
name1 = li['alt']
# print(name1)
img_url = li['data-src']
img_src = 'https:' + img_url
# self.get_image_info(img_src,name1)
self.img_url_list.append({'name': name1, 'img-src': img_src})
#使图片列表显示与list中的索引是一一对应的，这样下载时编号不会出错
for i,itm in enumerate(self.img_url_list):
index=str(i)
imgret=itm
imgname=imgret['name']
imgurl=imgret['img-src']
print(index)
print(imgname+imgurl)
self.te.append(str(i + 1) + ' ' + imgname+imgurl+ '\r\n')
我们提取了图片数据后，储存在一个list中，同时显示到文本框中。
三、图片下载
图片下载，其实是将当前网址指向的图片保存到本地，使用request.urlretrieve函数：
request.urlretrieve(urlpath, filename=fl)
因为我们已经获取了网页的图片列表，并保存在list中，此时无论是全下载还是单张下载，只需要对list中的元素进行操作即可。
