discord.py - 在discord.py中实现免费字典Api时出错

Question

我正在尝试实现这个 api，但代码每次都说错误。
到目前为止我的代码:

@client.command()
async def mean(ctx,word):  
    response = requests.get(f"https://api.dictionaryapi.dev/api/v2/entries/en/{word}")
    if response.status_code == 404:
        await ctx.send("No such word")
        return
    else:
        wordx = response.json()
        the_dictionary = wordx[0]
        meanings = the_dictionary['meanings']
        definitions = meanings[0]
        definition = definitions['definitions']
        meaningg = definition[0]
        meaning = meaningg['definition']
        example = meaningg.get('example',['None'])
        synonymslist = meaningg.get("synonyms",['None'])
        if isinstance(synonymslist,str):
            synonymslist = [synonymslist]
            pass
        synonyms = ','.join(synonymslist)
        deffinal= discord.Embed(title=f"`{word.upper()}`")
        deffinal.add_field(name = "Definition", value=f"{meaning}")
        deffinal.add_field(name = 'Example', value = f"{example}")
        deffinal.add_field(name = "Synonyms", value = f"{synonyms}")
        await ctx.channel.send(embed = deffinal)

这是错误消息:

Answer 1

您的错误不是来自对字典 api 的 API 调用，而是来自您对 discord api 的调用。
错误消息说 discord.errors.HTTPException: [...] In embed.fields.2.value: This field is required .
所以错误来自嵌入中的空字段!该字段具有索引 2所以实际上是第三个字段( Synonyms )导致了问题。
在添加字段之前，您可以简单地检查字符串是否为空。如果它是空的，就不要添加它。

deffinal= discord.Embed(title=f"`{word.upper()}`")
if meaning:
    deffinal.add_field(name = "Definition", value=f"{meaning}")

if example:
    deffinal.add_field(name = 'Example', value = f"{example}")

if synonyms:
    deffinal.add_field(name = "Synonyms", value = f"{synonyms}")

@client.command()
async def mean(ctx,word):  
    response = requests.get(f"https://api.dictionaryapi.dev/api/v2/entries/en/{word}")
    if response.status_code == 404:
        await ctx.send("No such word")
        return
    else:
        wordx = response.json()
        the_dictionary = wordx[0]
        meanings = the_dictionary['meanings']
        definitions = meanings[0]
        definition = definitions['definitions']
        meaningg = definition[0]
        meaning = meaningg['definition']
        example = meaningg.get('example',['None'])
        synonymslist = meaningg.get("synonyms",['None'])
        if isinstance(synonymslist,str):
            synonymslist = [synonymslist]
            pass
        synonyms = ','.join(synonymslist)

        deffinal= discord.Embed(title=f"`{word.upper()}`")
        if meaning:
            deffinal.add_field(name = "Definition", value=f"{meaning}")

        if example:
            deffinal.add_field(name = 'Example', value = f"{example}")

        if synonyms:
            deffinal.add_field(name = "Synonyms", value = f"{synonyms}")

        await ctx.channel.send(embed = deffinal)
