我正在嘗試使用TGRCode API 創建一個 Discord 命令，該命令回傳有關 Super Mario Maker 2 中關卡的資訊。但是，我遇到了問題。
如果該級別沒有，例如，清除條件，那么它會拋出一個鍵錯誤并停止命令。我知道它是做什么的，因為它只是不存在于 API 回傳的 JSON 中，而不是空字串或任何東西。
但是，問題是我不確定如何處理它。
（我正在嘗試使用AIOHTTP接收資訊）
我試過使用
if clear_condition == None:
clear_condition = "None"
那只是回傳一個 KeyError 我也嘗試過
if clear_condition_name not in response:
clear_condition_name = "None"
那只是回傳一個錯誤，說ClientResponse不可迭代。
我試過（帶和不帶引號）
if "clear_condition_name" not in response.json():
clear_condition_name = "None"
這只是吐出另一個關鍵錯誤。
我還查看了 Career Karma 的這篇文章，但這并沒有幫助，因為我不是定義字典的人。
這是我當前的代碼：
@commands.command()
async def smm2_lookup_level(self, ctx, code):
await ctx.reply(f"Getting level information of level with code `{code}`")
print(f"{ctx.author.name} has requested to get all information for {code}.")
MAIN = f"https://tgrcode.com/mm2/level_info/{code}"
async with request("GET", MAIN, headers={}) as response:
if response.status == 200:
print("The TGRCode API returned OK; getting info...")
data = await response.json()
title = data["name"]
description = data["description"]
upload_date = data["uploaded_pretty"]
course_id = data["course_id"]
style = data["game_style_name"]
theme = data["theme_name"]
difficulty = data["difficulty_name"]
tags = data["tags_name"]
upload_time = data["upload_time_pretty"]
number_of_comments = data["num_comments"]
clear_condition_name = data["clear_condition_name"]
clear_condition_magnitude = data["clear_condition_magnitude"]
clears = data["clears"]
attempts = data["attempts"]
clear_rate = data["clear_rate"]
plays = data["plays"]
likes = data["likes"]
boos = data["boos"]
thumbnail = f"https://tgrcode.com/mm2/level_thumbnail/{code}"
map = f"https://tgrcode.com/mm2/level_entire_thumbnail/{code}"
if clear_condition_name not in response.json():
clear_condition_name = "None"
clear_condition_magnitude = ""
if "clear_condition_magnitude" not in response.json():
clear_condition_name = "None"
clear_condition_magnitude = ""
if "description" not in response.json():
description = ""
if "tags" not in response.json():
tags = "None"
embed = discord.Embed(title="SMM2 Level Information.")
embed.add_field(name="Level Name", value=title, inline=True)
embed.add_field(name="Level Description", value=description, inline=True)
embed.add_field(name="Level Code", value=course_id, inline=True)
embed.add_field(name="Level Style", value=style, inline=True)
embed.add_field(name="Level Theme", value=theme, inline=True)
embed.add_field(name="Level Difficulty", value=difficulty, inline=True)
embed.add_field(name="Tags", value=tags, inline=True)
embed.add_field(name="Upload Date", value=upload_date, inline=True)
embed.add_field(name="Time taken to Clearcheck Course", value=upload_time, inline=True)
embed.add_field(name="Clear Condition Information", value=f"{clear_condition_name} {clear_condition_magnitude}.", inline=True)
embed.add_field(name="Clear Information", value=f"Clears: {clears}\nAttemps: {attempts}\nPlays: {plays}\nClear Rate: {clear_rate}.")
embed.add_field(name="Number of Comments", value=number_of_comments, inline=True)
embed.set_thumbnail(url=thumbnail)
embed.set_image(url=map)
embed.add_field(name="Like:Boo Ratio", value=f"{likes}:{boos}")
await ctx.send(f"{ctx.author.mention} Here's the information for level with code `{code}`:", embed=embed)
else:
await ctx.send(f"I was unable to retrieve the information. Try again, if not the TGRCode API may be down, or there is an error on my end.\n*Response Status: {response.status}*")
print(f"I was unable to retrieve the information from TGRCode.\n*Response Status: {response.status}*")
因此，盡管我嘗試過的所有方法都沒有幫助，但我希望我能在這里找到一些。謝謝。
uj5u.com熱心網友回復：
問題是您在宣告clear_condition_name變數時試圖讀取該鍵。您應該檢查回應資料字典是否有這樣的鍵，如下所示：
clear_condition_name = data["clear_condition_name"] if "clear_condition_name" in data.keys() else "None"
