java - 如何使用 Google Sign in 授权 Youtube Data api 请求？

Question

我正在使用 Google 登录对我的用户进行身份验证和授权使用我的应用。现在我想使用 Youtube Data api 发出 api 请求来提取用户可能拥有的 channel 列表。

在文档中，它说我需要一个用于“Authorizaiton:Bearer”的 OAuth token https://developers.google.com/youtube/v3/guides/auth/installed-apps#callinganapi

如何使用我通过 Google Sign 登录的帐户并获取所需的 OAuth token ？

更新:在这里尝试了答案:Authorize youtube data api request using google sign in api然而，它不起作用。在跟踪一个类和一些包之后，我放置的单独线程似乎挂起并且不返回任何内容。

Google 登录生成器

    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    boolean isLoggedIn = accessToken != null && !accessToken.isExpired();
    Log.d("frag","login status" + String.valueOf(isLoggedIn));

    scope = new Scope("https://www.googleapis.com/auth/yt-analytics.readonly");
    scopeTwo = new Scope("https://www.googleapis.com/auth/youtube.readonly");
    gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestScopes(scope,scopeTwo)
           // .requestIdToken(getString(R.string.server_client_id))
            .requestServerAuthCode(getString(R.string.server_client_id))
            .build();

    googleSignInClient = GoogleSignIn.getClient(getActivity(), gso);

运行 Google Sign 和 API 的 Intent

            api = new GoogleApiClient.Builder(getContext())
                    .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                    .build();
            api.connect();


            Intent signInIntent = googleSignInClient.getSignInIntent();
            startActivityForResult(signInIntent, 21);

            Intent intent = Auth.GoogleSignInApi.getSignInIntent(api);
            startActivityForResult(intent,115);

第 1 步.获取用户电子邮件

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1001) {
        if (resultCode == RESULT_OK) {
            email = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
            request();
        } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "You must pick an account", Toast.LENGTH_SHORT).show();
            //finish();
        }
    } 
    super.onActivityResult(requestCode, resultCode, data);
}

protected void pickUserAccount() {
    String[] accountTypes = new String[]{"com.google"};
    Intent intent = AccountPicker.newChooseAccountIntent(null, null,
            accountTypes, true, null, null, null, null);

    try {
        startActivityForResult(intent, 1001);
    } catch (ActivityNotFoundException e) {
        Toast.makeText(this, "Your phone seems to be missing Google Play Services.", Toast.LENGTH_SHORT).show();
    }
}

第2步.获取凭据

public String getTokenWithEmailOnly(Context context, String email){
    String token = null;

    try {
        token = GoogleAuthUtil.getToken(context, email, "oauth2:https://www.googleapis.com/auth/youtube");

        TokenResponse tokenResponse = new TokenResponse();
        tokenResponse.setAccessToken(token);
        Credential credential = createCredentialWithAccessTokenOnly(tokenResponse);
        YouTube youtube = new YouTube.Builder(new NetHttpTransport(), new JacksonFactory(), credential).build();

    } catch (Throwable t) {

    }

    return token;
}

private Credential createCredentialWithAccessTokenOnly(TokenResponse tokenResponse) {
    return (new Credential(BearerToken.authorizationHeaderAccessMethod())).setFromTokenResponse(
            tokenResponse);
}
