spotify-web-api-node: authorizationCodeGrant() 给出 400 - 错误请求

spotify-web-api-node: authorizationCodeGrant() give a 400 - Bad Request

我使用 npm 模块 spotify-web-api-node 来使用 Spotify Web API 而无需编写大量代码。

我按照 here 给出的示例从 Spotify 获得了 授权码 。然后,我使用此 code 从 Spotify 获取 Access TokenRefresh Token 并执行所有操作我想要的动作。

当我在这里询问 Access Token 时出现问题:

router.get('/auth/spotify/success', (req, res, next) => {
    let spotifyApi = new SpotifyWebApi({
        clientId: 'my-client-id',
        clientSecret: 'my-client-secret',
        redirectUri: 'http://localhost:3000/'
                 // The URI is registered to Spotify redirect URIs
    })

    const code = req.query.code

    spotifyApi.authorizationCodeGrant(code)
    .then(data => {
        console.log('The token expires in ' + data.body['expires_in'])
        console.log('The access token is ' + data.body['access_token'])
        console.log('The refresh token is ' + data.body['refresh_token'])

        // Set the access token on the API object to use it in later calls
        spotifyApi.setAccessToken(data.body['access_token'])
        spotifyApi.setRefreshToken(data.body['refresh_token'])


        res.render('index', { title: 'Connected !' })
    })
    .catch(err => {
        console.log('Something went wrong!', err);

        res.render('index', { title: 'Error !' })
    })
})

此代码记录:

Something went wrong! { [WebapiError: Bad Request] name: 'WebapiError', message: 'Bad Request', statusCode: 400 }

我的代码有什么问题?我该怎么做才能从 Spotify 获得访问令牌和刷新令牌?谢谢!

问题很简单(我浪费了2天时间...)。如 Spotify API 文档 here 中所述。 谈到 redirect_uri 参数,文档说:

TLDR 阅读此内容:

The value of this parameter must exactly match the value of redirect_uri supplied when requesting the authorization code.

所以在我的代码中:

router.get('/auth/spotify/success', (req, res, next) => {
    let spotifyApi = new SpotifyWebApi({
        clientId: 'my-client-id',
        clientSecret: 'my-client-secret',
        redirectUri: 'http://localhost:3000/'
                 // Changing this...
        redirectUri: 'http://localhost:3000/auth/spotify/success'
                 // ...to this made it work !
    })

    // [...]

我也很抱歉,因为没有人能找到问题,因为我没有给你完整的代码 "the first part works !"。是的,它有效,但它包含有关我的问题的有用线索。
