读取 JSON 文件以获得最高分辨率图像 (Last.FM)
Read JSON file to get highest resolution image (Last.FM)
因此，我正在开发一个项目，每次在特定日期（例如 'Mon 22:00:00'）都会发送一条 Discord 消息。该消息包括我那周听得最多的专辑。每当我得到 URL 到 JSON，其中包括多个 link 到图像时，我就得到了代码。这是我得到的 JSON 响应：

我想获取 "size": "" 上方的 link，因为此图像具有最高分辨率。我怎样才能做到这一点？我使用 Python 来制作 Discord 机器人，所以如果你能用 Python 语言解释，那就太好了！提前致谢！
要将 JSON 字符串转换为 Python 对象，您可以使用：
import json
album_data = json.loads(album_json_string)
要提取 'mega' 图像 URL，您可以使用列表理解遍历图像列表：
images = album_data['album']['image']
mega_images = [i for i in images if i['size'] == 'mega']
try:
mega_image_url = mega_images[0]['image']
except IndexError:
#do something if the mega URL isn't present
因此，我正在开发一个项目，每次在特定日期（例如 'Mon 22:00:00'）都会发送一条 Discord 消息。该消息包括我那周听得最多的专辑。每当我得到 URL 到 JSON，其中包括多个 link 到图像时，我就得到了代码。这是我得到的 JSON 响应：

我想获取 "size": "" 上方的 link，因为此图像具有最高分辨率。我怎样才能做到这一点？我使用 Python 来制作 Discord 机器人，所以如果你能用 Python 语言解释，那就太好了！提前致谢！
要将 JSON 字符串转换为 Python 对象，您可以使用：
import json
album_data = json.loads(album_json_string)
要提取 'mega' 图像 URL，您可以使用列表理解遍历图像列表：
images = album_data['album']['image']
mega_images = [i for i in images if i['size'] == 'mega']
try:
mega_image_url = mega_images[0]['image']
except IndexError:
#do something if the mega URL isn't present
