我正在开发一个应用程序，该应用程序应该可以从用户 YouTube 帐户中获取分析数据。我可以在我的应用程序的 web 视图中使用以下 url 从 Google 检索授权代码。
https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/yt-analytics.readonly&approval_prompt=force&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&client_id=762546229188.apps.googleusercontent.com&access_type=offline
我从页面标题中检索代码，然后使用 Java 的 substring 方法切断成功。但是，当我去获取访问令牌时，它只会返回"error" : "invalid_grant"
HttpClient client = new DefaultHttpClient(); //new HTTP client
HttpPost post = new HttpPost("https://accounts.google.com/o/oauth2/token"); //where to post to
List<NameValuePair> pairs = new ArrayList<NameValuePair>(); //construct the values to hand to Google
Log.v("KUZMA", arg0[0]); //personal logcat message
pairs.add(new BasicNameValuePair("code", arg0[0])); //in arg0[0] lives the auth code
pairs.add(new BasicNameValuePair("client_id", CLIENT_ID)); //I store the Client_id as a static variable at the beginning of my class
//Log.v("Kuzma", CLIENT_ID);
//pairs.add(new BasicNameValuePair("client_secret", "*******"));
pairs.add(new BasicNameValuePair("redirect_uri", "http://localhost"));
pairs.add(new BasicNameValuePair("grant_type", "authorization_code")); //Leave this line how it is
String responseBody = null;
try {
post.setEntity(new UrlEncodedFormEntity(pairs));
org.apache.http.HttpResponse response = client.execute(post);
responseBody = EntityUtils.toString(response.getEntity());
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.v("KUZMA", responseBody); // That just logs it into logCat
//output.setText("something happened?");
return null;
所以我想我最大的问题是我没有客户端密码，但谷歌没有为我提供已安装的应用程序。有没有解决的办法？我也玩过 Google Play Services，但也无法让它工作，但如果你知道它是如何工作的，那就太好了！
