node.js - 如何进行多个API调用

Question

我尝试对 Riot API 进行多个 API 调用，但在 .catch(err=>) 旁边收到“意外 token ”语法错误。抱歉，如果我问了一个愚蠢的问题，这是我第一次使用 Node.js...

const fetch = require('node-fetch');

module.exports = (app) => {

    let champname;

    app.post('/search-champ', (req, res) => {
        champname = req.body.champname;   //added by hu
    let server = req.body.server; 
    let id= "80339518";
        //need to call api to get champions
     const apiId = 'RGAPI-da5d88a2-c56e-4b32-a640-9933a53c9058';
        const baseUrl = 'https://'+ server+'/api.riotgames.com/lol/summoner/v3/summoners/by-name/'+ champname + '?api_key='+apiId;


        const userLocation = (url1, url2, champname) => {

            let newUrl = url1 + champname + url2;
            return newUrl;
        };

        const apiUrl = 'https://euw1.api.riotgames.com/lol/summoner/v3/summoners/by-name/'+ champname + '?api_key='+apiId;

        fetch(apiUrl)
            .then(res => res.json())
            .then(data => {
                var id = data.accountId;
                console.log(data)

             const apiUrl2 = 'https://euw1.api.riotgames.com/lol/match/v3/matchlists/by-account/'+id + '?api_key='+apiId;

                fetch(apiUrl2)
                .then(res => res.json())
                .then(data => {
                    var id2=data.matches[1].gameId;
                    res.send({ data });
                    console.log('match1', data.matches[0].gameId)


                const apiUrl3='https://euw1.api.riotgames.com/lol/match/v3/matches/'+id2 + '?api_key='+apiId;

                fetch(apiUrl3)
                 .then(res => res.json())
                .then(data => {
                     res.send({ data });
                    console.log(data)

                .catch(err => {
                    res.redirect('/error');
                });
              .catch(err => {
                    res.redirect('/error');
                });
            })
            .catch(err => {
                res.redirect('/error');
            });


    })

    })
    app.get('/search-location-champ', (req, res) => {
        //build api URL with user zip
        const apiId = 'RGAPI-4b602b1a-e6aa-4c24-b88f-d0aab6467fa8';
        const baseUrl = 'https://euw1.api.riotgames.com/lol/summoner/v3/summoners/by-name/'+ champname + '?api_key='+apiId;


        const userLocation = (url1, url2, champname) => {

            let newUrl = url1 + champname + url2;
            return newUrl;
        };

        const apiUrl = 'https://euw1.api.riotgames.com/lol/summoner/v3/summoners/by-name/'+ champname + '?api_key='+apiId;


        fetch(apiUrl)
            .then(res => res.json())
            .then(data => {
                res.send({ data });
            })
            .catch(err => {
                res.redirect('/error');
            });


    })
}

检查您的代码，关闭 .then 回调的大括号和括号丢失或位置不正确，我尝试在此处修复它。

fetch(apiUrl)
        .then(res => res.json())
        .then(data => {
            var id = data.accountId;
            console.log(data)

         const apiUrl2 = 'https://euw1.api.riotgames.com/lol/match/v3/matchlists/by- 
          account/'+id + '?api_key='+apiId;

            fetch(apiUrl2)
            .then(res => res.json())
            .then(data => {
                var id2=data.matches[1].gameId;
                res.send({ data });
                console.log('match1', data.matches[0].gameId)


            const apiUrl3='https://euw1.api.riotgames.com/lol/match/v3/matches/'+id2 
                  + '?api_key='+apiId;

            fetch(apiUrl3)
             .then(res => res.json())
            .then(data => {
                 res.send({ data });
                console.log(data)
            })
            .catch(err => {
                res.redirect('/error');
            });
           })
          .catch(err => {
                res.redirect('/error');
          });
        })
        .catch(err => {
            res.redirect('/error');
      });
