篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了spotify web api授权码授予thelinmichael / spotify-web-api-java android相关的知识,希望对你有一定的参考价值。
我有问题使用授权代码授权授权spotify web api。我知道我必须填写我的客户端ID,客户端密码并将uri重定向到字符串,但我不知道如何获取名为code的字符串,这是获取访问令牌所必需的。
final String clientId = "<your_client_id>";
final String clientSecret = "<your_client_secret>";
final String redirectURI = "<your_redirect_uri>";
final Api api = Api.builder()
.clientId(clientId)
.clientSecret(clientSecret)
.redirectURI(redirectURI)
.build();
/* Set the necessary scopes that the application will need from the user */
final List<String> scopes = Arrays.asList("user-read-private", "user-read-email");
/* Set a state. This is used to prevent cross site request forgeries. */
final String state = "someExpectedStateString";
String authorizeURL = api.createAuthorizeURL(scopes, state);
/* Continue by sending the user to the authorizeURL, which will look something like
https://accounts.spotify.com:443/authorize?client_id=5fe01282e44241328a84e7c5cc169165&response_type=code&redirect_uri=https://example.com/callback&scope=user-read-private%20user-read-email&state=some-state-of-my-choice
*/
然后
/* Application details necessary to get an access token */
final String code = "<insert code>"; //I don't know where I get the value for this string from
/* Make a token request. Asynchronous requests are made with the .getAsync method and synchronous requests
* are made with the .get method. This holds for all type of requests. */
final SettableFuture<AuthorizationCodeCredentials> authorizationCodeCredentialsFuture = api.authorizationCodeGrant(code).build().getAsync();
/* Add callbacks to handle success and failure */
Futures.addCallback(authorizationCodeCredentialsFuture, new FutureCallback<AuthorizationCodeCredentials>() {
@Override
public void onSuccess(AuthorizationCodeCredentials authorizationCodeCredentials) {
/* The tokens were retrieved successfully! */
/* Set the access token and refresh token so that they are used whenever needed */
api.setAccessToken(authorizationCodeCredentials.getAccessToken());
api.setRefreshToken(authorizationCodeCredentials.getRefreshToken());
}
@Override
public void onFailure(Throwable throwable) {
/* Let's say that the client id is invalid, or the code has been used more than once,
* the request will fail. Why it fails is written in the throwable's message. */
}
});
您知道如何获取此代码并成功获取访问令牌吗?
谢谢!
您可以在Authorization Code Flow的说明中阅读,您需要将用户发送到Spotify URL。此URL在authorizeURL字符串中给出:
/* Continue by sending the user to the authorizeURL, which will look
something like
https://accounts.spotify.com:443/authorize?client_id=5fe01282e44241328a84e7c5cc169165&response_type=code&redirect_uri=https://example.com/callback&scope=user-read-private%20user-read-email&state=some-state-of-my-choice
*/
用户登录并获得访问给定范围的应用程序权限后,Spotify会将用户重定向到回调URL。这就是它变得复杂的地步。您需要在回调网址中接收Spotify提供的代码参数。此代码参数是正在进行的过程所需的值。您正在使用的spotify-web-api-java不提供接收此请求的任何内容。你需要通过使用例如一个Spring RESTful Web Service。
我现在已经解决了这个问题。
您不必制作Web服务!解决方案实际上非常简单。你只需要创建一个Intent
Intent.ACTION_VIEW
作为第一个参数,并将您的url作为第二个参数,并以Intent作为参数调用startActivity。然后你必须添加这个
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="callback"
android:scheme="yourcustomprotocol" />
</intent-filter>
清单中的活动标记,最后但并非最不重要的是捕获回调
onNewIntent(最终意图)
在这里你可以获得意图的url,你可以从中提取代码。
