Spotify API 错误 401 - 尝试将曲目放入用户的库中答案

【问题标题】：Spotify API Error 401 - Attempting to PUT tracks into a user's librarySpotify API 错误 401 - 尝试将曲目放入用户的库中

【问题描述】：

只是想知道是否有人能在此代码中发现会引发 401 未授权错误的问题？

我有几个类似的功能，所有功能都很好，通过 Spotify Web API 写入 GET 数据（使用 axios），但由于某种原因，我的 PUT 请求引发了错误。

这是此端点的relevant Spotify documentation。

基本上，数据作为 JSON 对象数组从客户端发送到服务器，其中包含我想保存到授权 Spotify 帐户的曲目的详细信息，以及作为参数的有效访问令牌。我知道令牌是有效的，因为在此步骤之前我正在通过不同的 GET 获取用户的帐户数据。而且我知道该 url 已正确连接，因为它已在错误详细信息中打印出来：

app.put("/migration-data/put/:token", async (req, res) => {
    console.log(`Migrating data to new account using token ${req.params.token.substring(0, 4)}...\n`);
    const toClientPutData = await putData(req.params.token, req.body);
    res.json(toClientPutData);
});

const putData = async (token, data) => {
    const putResults = {};

    const spotifyAPI_PutTracks = async (trackData, index=0) => {
        try {           
            const recurse = ((trackData.length - 1) - (index + 50)) > 0;

            const offset = recurse ? 49 : (trackData.length - index) - 1;
            var tracksThisQuery = "";

            for (var i = index; i < (index + offset); i++) {
                tracksThisQuery+=`${trackData[i].id}%2C`
            }

            tracksThisQuery+=`${trackData[(index + offset)].id}`

            return puttingTracks.data;

        } catch (apiError) {
            console.log(apiError);
        }
    }

    const { user, savedTracks, savedAlbums, following, playlists } = data;

    if (token) {
        // put tracks
        const putTracksData = await spotifyAPI_PutTracks(savedTracks);
        putResults["putTracks"] = putTracksData;
    }

    return putResults;
}

【解决方案1】：

想通了 - PUT 需要在 url 之后，但在 headers 之前有一个额外的 data 参数。我刚刚在第二个参数槽中插入了一个空对象字面量，然后我们就开始比赛了。
