【问题描述】：

我正在尝试使用以下内容访问 spotify 令牌

OkHttpClient client = new OkHttpClient();

        String state = "azertyuiopmlkjhg";//TODO random string
        String scope = "user-read-private user-read-email";

        URIBuilder ub = new URIBuilder("https://accounts.spotify.com/authorize?")
                .addParameter("client_id", CLIENT_ID)
                .addParameter("response_type", "token")
                .addParameter("scope", scope)
                .addParameter("redirect_uri", REDIRECT_URI)
                .addParameter("state", state);
        String url = ub.toString();
        System.out.println(url);

        Request request = new Request.Builder()
                .header("Content-Type", "application/json")
                .url(url)
                .build();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                e.printStackTrace();
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                final String myResponse = response.body().string();
                final String networkResponse = response.networkResponse().request().url().toString();
                System.out.println(myResponse);
                System.out.println(networkResponse);
                if (response.isSuccessful()) {
                    MainActivity.this.runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            textView.setText("Success \n"+myResponse);
                        }
                    });
                }
            }
        });

生成的 URL https://accounts.spotify.com/authorize?client_id=e...0&response_type=token&scope=user-read-private+user-read-email&redirect_uri=https%3A%2F%2Faccounts.spotify.com%2Fauthorize&state=azertyuiopmlkjhg 重定向到包含我想要的令牌的链接 https://accounts.spotify.com/authorize#access_token=B...g&token_type=Bearer&expires_in=3600&state=azertyuiopmlkjhg

查询返回应该是：access_token；令牌类型； expires_in 和状态但我得到了一些 HTML 作为响应

<html id="app" lang="fr" dir="ltr" ng-csp ng-strict-di>
    <head>
      <meta charset="utf-8">
      <title ng-bind="(&#39;loginTitle&#39; | localize) + &#39; - Spotify&#39;">Spotify</title>

    </html>

【问题讨论】：

GET 请求重定向到一个 spotify 登录屏幕，它应该呈现在例如浏览器。只有在用户确认允许应用使用请求的信息后，才会向您的回调 url 发送一个令牌。

【解决方案1】：

这是一个用于 spotify 的示例身份验证流程

https://github.com/yschimke/okurl/blob/0abaa8510dd5466d5e9a08ebe33a009c491749bf/src/main/kotlin/com/baulsupp/okurl/services/spotify/SpotifyAuthFlow.kt

      val scopesString = URLEncoder.encode(scopes.joinToString(" "), "UTF-8")

      val loginUrl =
        "https://accounts.spotify.com/authorize?client_id=$clientId&response_type=code&state=x&redirect_uri=${s.redirectUri}&scope=$scopesString"

      outputHandler.openLink(loginUrl)

      val code = s.waitForCode()

      val tokenUrl = "https://accounts.spotify.com/api/token"
      val body = FormBody.Builder().add("client_id", clientId)
        .add("redirect_uri", s.redirectUri)
        .add("code", code)
        .add("grant_type", "authorization_code")
        .build()
      val request = Request.Builder().header(
        "Authorization",
        Credentials.basic(clientId, clientSecret)
      )
        .url(tokenUrl)
        .method("POST", body)
        .build()

      val responseMap = client.queryMap<Any>(request)

      return Oauth2Token(
        responseMap["access_token"] as String,
        responseMap["refresh_token"] as String, clientId, clientSecret
      )

$ okurl --authorize=spotify
Accounts: https://developer.spotify.com/my-applications/
Spotify Client Id []: xxx
Spotify Client Secret []:
Scopes [playlist-read-private,playlist-read-collaborative,playlist-modify-public,playlist-modify-private,streaming,ugc-image-upload,user-follow-modify,user-follow-read,user-library-read,user-library-modify,user-read-private,user-read-birthdate,user-read-email,user-top-read]:

【讨论】：

感谢您的回答，不幸的是，该示例在 Kotlin 中，我无法在 Java 中使用它来响应我的问题。

【解决方案2】：

我最终关注了 following tutorial 并使用 spotify 身份验证服务

请注意，AuthenticationRequest 和 AuthenticationClient 现在称为 AuthorizationRequest 和 AuthorizationClient
