Question

我正在尝试编写 Cursedimage subreddit 命令，但我不断收到此错误

(node:10488) UnhandledPromiseRejectionWarning: SyntaxError: Unexpected token o in JSON at position 1

这是我的代码：

case 'cursedimage':
                    fetch('https://www.reddit.com/r/cursedimages/random/.json').then(response => {
                    let content = JSON.parse(response.body);
                    var image = content[0].data.children[0].data.url;
                    let permalink = content[0].data.children[0].data.permalink;
                    let memeUrl = `https://reddit.com${permalink}`;
                    let memeImage = content[0].data.children[0].data.url;
                    let memeTitle = content[0].data.children[0].data.title;
                    let memeUpvotes = content[0].data.children[0].data.ups;
                    let memeNumComments = content[0].data.children[0].data.num_comments;
                    const cursedembed = new Discord.MessageEmbed()
                    .setColor('RANDOM')
                    .setTitle(content[0].data.children[0].data.title)
                    .setURL(`${memeUrl}`)
                    .setImage(image)
                    .setFooter(`? ${memeUpvotes} ? ${memeNumComments}`)
                    .setTimestamp()
                message.channel.send(cursedembed);
                });
                break

你能试试这段代码吗？

fetch('https://www.reddit.com/r/cursedimages/random/.json').then(response => response.json()).then(response => {
  let content = response.data;
  var image = content[0].data.children[0].data.url;
  let permalink = content[0].data.children[0].data.permalink;
  let memeUrl = `https://reddit.com${permalink}`;
  let memeImage = content[0].data.children[0].data.url;
  let memeTitle = content[0].data.children[0].data.title;
  let memeUpvotes = content[0].data.children[0].data.ups;
  let memeNumComments = content[0].data.children[0].data.num_comments;
  const cursedembed = new Discord.MessageEmbed()
    .setColor('RANDOM')
    .setTitle(content[0].data.children[0].data.title)
    .setURL(`${memeUrl}`)
    .setImage(image)
    .setFooter(`? ${memeUpvotes} ? ${memeNumComments}`)
    .setTimestamp()
  message.channel.send(cursedembed);
});
