python - 我有错误 TypeError: Object of type method is not JSON serializable
问题描述
所以，我正在制作这个脚本，使用 Last.FM API 检查一周中播放次数最多的歌曲。我用 Python 制作了这个脚本：
import discord
import datetime
from discord import member
from discord.ext import commands, tasks
from discord.utils import get
from datetime import datetime
import threading
import requests
import json
from requests.api import request
class MostPlayer(commands.Cog):
def __init__(self, bot):
self.bot = bot
self.lastfmmostplayed.start()
@tasks.loop(seconds=1)
async def lastfmmostplayed(self):
await self.bot.wait_until_ready()
now = datetime.now()
dt_string = now.strftime("%a %H:%M:%S")
if(dt_string == 'Sat 17:47:00'):
print("Time for a new song suggestion!")
tokens = open('./hidden/tokens.json')
tokenimport = json.load(tokens)
lastfmtoken = tokenimport['lastfmtoken']
# Album Chart - No. 1
requesturl_no1album = requests.get('http://ws.audioscrobbler.com/2.0/?method=user.getweeklyalbumchart&user=QuinnTT&api_key=' + lastfmtoken + '&format=json')
parsed = requesturl_no1album.json()
album = parsed['weeklyalbumchart']['album']
sorted_album = sorted(album, key = lambda song:song["playcount"])
most_listened_song = sorted_album[-1] # last element is the one with the biggest playcount
album_chart_artist = most_listened_song['artist']['#text']
album_chart_name = most_listened_song['name']
album_chart_playcount = most_listened_song['playcount']
album_chart_url = most_listened_song['url']
*_, album_chart_artist_url, album_chart_name_url = album_chart_url.split("/")
no1_info_url = ('http://ws.audioscrobbler.com/2.0/?method=album.getinfo&api_key=' + lastfmtoken + '&artist=' + album_chart_artist_url + '&album=' + album_chart_name_url + '&format=json')
request_no_info = (requests.get(no1_info_url)).json
album_data = json.dumps(request_no_info)
images = album_data['album']['image']
mega_images = [i for i in images if i['size'] == 'mega']
try:
mega_image_url = mega_images[0]['#text']
except IndexError:
mega_image_url = ""
embed_album=discord.Embed(title="Quinn's Album of the Week:", description=f"{album_chart_name} by {album_chart_artist}", color=0x9d30ab)
embed_album.set_footer(text=f"Quinn listened {album_chart_playcount}x to this album last week!")
embed_album.set_image(url=mega_image_url)
await self.bot.get_channel(850308124493086730).send(embed=embed_album)
else:
return
def setup(bot):
bot.add_cog(MostPlayer(bot))
但是，当我运行它时，我收到以下错误：
TypeError：类型方法的对象不是 JSON 可序列化的
我不知道错误是什么，所以这就是我在这里问的原因。以防万一，这里是从 Last.FM 获取的 JSON（第 38 行）。代码应该获取专辑图像的链接，以便我稍后可以在 Discord.py 嵌入中使用它。
