5.换一种方式,及时关闭stream importrequestsfromcontextlibimportclosingdefdownload_image_improve(): url='https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1504068152047&di=8b53bf6b8e5deb64c8ac726e260091aa&imgtype=0&src=http%3A%2F%2Fpic.baike.soso.com%2Fp%2F20140415%2Fbki-...
在Python3中,可以使用请求库(如requests)来下载图像。以下是一个完整的示例代码: 代码语言:txt 复制 import requests def download_image(url, save_path): response = requests.get(url) if response.status_code == 200: with open(save_path, 'wb') as file: file.write(response.content) print("图像下...
() sql = 'select image from msg limit 100' # image为事先爬取存到MySQL的图片链接地址 cur.execute(sql) img_link = cur.fetchall() return img_link def download(self, link): filename = re.findall(r'.*/(.+)', link)[0] try: pic = requests.get(link, headers=self.header) if pic...
pipinstallrequests 1. 实现步骤 导入所需的库 importrequestsimportos 1. 2. 定义一个函数来发送请求并下载图片 defdownload_image(url,save_path):response=requests.get(url)ifresponse.status_code==200:withopen(save_path,'wb')asf:f.write(response.content)print(f"图片已保存到:{save_path}")else:pri...
你可以使用Python中的requests库来下载图片。以下是一个简单的示例代码: importrequestsdefdownload_image(url, file_path):response = requests.get(url)ifresponse.status_code ==200:withopen(file_path,'wb')asfile: file.write(response.content)print(f"Image downloaded successfully to{file_path}")else:pri...
importrequestsimportosdefdownload_image(url,save_path):response=requests.get(url)withopen(save_path,'wb')asfile:file.write(response.content)url=" save_path="image.jpg"download_image(url,save_path)print("Image downloaded successfully!")
你可以通过以下命令安装这些库：```bashpip install requests beautifulsoup4```### 二、实现网页爬虫### 1. 发送HTTP请求首先，我们需要使用`requests`库来发送HTTP请求，获取网页的HTML内容。这里我们以一个包含图片的网页为例，比如一个图片分享网站。```pythonimport requestsurl = 'http://example.com/image_...
使用Python下载图像可以通过多种方式实现,以下是一种常见的方法: 使用Python的requests库发送HTTP请求下载图像文件。 代码语言:txt 复制 import requests def download_image(url, save_path): response = requests.get(url) with open(save_path, 'wb') as file: file.write(response.content) # 示例用法 image...
download_image(image_url, save_location) 在这个代码片段中,我们定义了一个名为download_image的函数,它接受两个参数:url(图片的URL)和save_path(本地保存图片的路径)。函数内部,我们使用requests.get()方法获取图片内容,然后以二进制写模式打开文件并将内容写入文件中。
