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documentation给出的示例从Spotify获取授权码。然后,我使用此代码从Spotify获取访问令牌和刷新令牌,并执行我想要的所有操作。
当我在此处询问访问令牌时会出现问题:
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 }
我的代码出了什么问题?如何从Spotify获取访问令牌和刷新令牌?谢谢!
答案 0 :(得分:2)
问题很简单(我浪费了2天......)。正如Spotify API文档here中所述。
说到文档所说的redirect_uri
参数:
TLDR请阅读:
此参数的值必须与请求授权代码时提供的redirect_uri的值完全匹配。
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 !
})
// [...]
我也道歉,因为没有人能找到问题,因为我没有给你整个代码说“第一部分有效!”。是的,它有效,但它包含有关我的问题的有用线索。
