如何使用Spotify API上传自定义播放列表封面图片？

Question

我在一个私有的node.js项目中，服务器上应该有一个端点来更新特定播放列表的封面图片。在这个端点里面我有这样的代码。

let playlistID = '7fOfY.......G5RFK3z';              // ID of already created playlist
let imgFile = '/9j/4AAQSkZJRg.......AgICAg';         // data:image/jpeg;base64
let spotifyAccessToken = 'DHdhw3.......DHdfLS8';     // valid access token


let options = {
    url: 'https://api.spotify.com/v1/playlists/' + playlistID + '/images',
    headers: {
         'Authorization': 'Bearer ' + spotifyAccessToken,
         'Content-Type': 'image/jpeg'
    },
    body: imgFile
}

request.put(options,(error, response) => {

    if(response.statusCode === 202) {
         console.log('Upload cover');
    } else {
         console.log(JSON.stringify(response));
    }

在终端中，它总是失败，Spotify中没有封面图片。有谁知道是什么问题吗？我该怎么做才能解决这个问题？https:/developer.spotify.comdocumentationweb-apireferenceplaylistsupload-custom-playlist-cover

EDIT:

Response object looks like this:

{"statusCode":400,
    "body":{
        "error": {
            "status": 400,
            "message": "Bad request."
            }
        },
    "headers":{
        "content-type": "application/json; charset=utf-8",
        "cache-control": "private",
        "max-age=0",

https:/www.base64decode.org 我从 此职位 可能有助于确保你的有效载荷正确解码为图像，你可以把base64字符串放在一个文本文件中，然后上传到这个网站，看看它是否能解码为你想要的图像。

如果你还没有这样做的话，从base64字符串的开头省略 "data:imagejpeg;base64 "也会有帮助。
