我正在为Google做oauth2，我可以获取授权码，但是我无法从授权码中获取访问令牌.

}

我尝试通过更新应用程序的产品名称进行操作.通过 解决方案 .但这没有帮助.

I have tried with by updating the product name of the application. by this solution.But it not helped.

这里是获取AccessToken的代码.GetAccessToken

Here is the code to obtain the get the AccessToken.GetAccessToken

public class GetAccessToken {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public GetAccessToken() {}
List < NameValuePair > params = new ArrayList < NameValuePair > ();
Map < String, String > mapn;
DefaultHttpClient httpClient;
HttpPost httpPost;
public JSONObject gettoken(String address, String token, String client_id, String client_secret, String redirect_uri, String grant_type) {
    // Making HTTP request
    try {
        // DefaultHttpClient
        httpClient = new DefaultHttpClient();
        httpPost = new HttpPost(address);
        params.add(new BasicNameValuePair("code", token));
        params.add(new BasicNameValuePair("client_id", client_id));
        params.add(new BasicNameValuePair("client_secret", client_secret));
        params.add(new BasicNameValuePair("redirect_uri", redirect_uri));
        params.add(new BasicNameValuePair("grant_type", grant_type));
        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
        httpPost.setEntity(new UrlEncodedFormEntity(params));
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
            is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        json = sb.toString();
        Log.e("JSONStr", json);
    } catch (Exception e) {
        e.getMessage();
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }
    // Parse the String to a JSON Object
    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
    }
    // Return JSON String
    return jObj;
}}

用于解析json_response的代码.

Code to parse the json_response.

TokenGet.class

 private class TokenGet extends AsyncTask < String, String, JSONObject > {
     private ProgressDialog pDialog;
     String Code;@
     Override
     protected void onPreExecute() {
         super.onPreExecute();
         pDialog = new ProgressDialog(MainActivity.this);
         pDialog.setMessage("Contacting Google ...");
         pDialog.setIndeterminate(false);
         pDialog.setCancelable(true);
         Code = pref.getString("Code", "");
         pDialog.show();
     }@
     Override
     protected JSONObject doInBackground(String...args) {
         GetAccessToken jParser = new GetAccessToken();
         JSONObject json = jParser.gettoken(TOKEN_URL, authCode, CLIENT_ID, CLIENT_SECRET, REDIRECT_URI, GRANT_TYPE);
         return json;
     }@
     Override
     protected void onPostExecute(JSONObject json) {
         pDialog.dismiss();
         if (json != null) {
             try {
                 String tok = json.getString("access_token");
                 String expire = json.getString("expires_in");
                 String refresh = json.getString("refresh_token");
                 Log.d("json", json.toString());
                 Log.d("Token Access", tok);
                 Log.d("Expire", expire);
                 Log.d("Refresh", refresh);
                 auth.setText("Authenticated");
                 Access.setText("Access Token:" + tok + "\nExpires:" + expire + "\nRefresh Token:" + refresh);
             } catch (JSONException e) {
                 // TODO Auto-generated catch block
                 e.printStackTrace();
             }
         } else {
             Toast.makeText(getApplicationContext(), "Network Error", Toast.LENGTH_SHORT).show();
             pDialog.dismiss();
         }
     }
 }

给我，有任何建议...

Give Me,Any Suggestion...

推荐答案

好，我在使用AsyncTask时遇到了一些麻烦，例如您:

Ok, i had some troubles like you using AsyncTask:

因此，我建议您使用VolleY，使用此库非常容易执行您的操作...

So, i recommend you to use VolleY, its very easy to do what you are doing with this library...

我认为您的问题在于您没有使用正确的字符集...请尝试将其添加到代码中:

I think your problema is that you are not using the correct Charset... try adding this to your code:

httpPost.setHeader("Content-Type"，"application/x-www-form-urlencoded; charset = utf-8");

httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");

如果它不起作用，请告诉我...

if it doesnt work, lets me know...

如果您有兴趣使用Volley，请让我知道....我不是专家，但是我可以为您提供帮助，实际上我正在使用它.

If you are interested to use Volley lets me know.... i am not an expert, but i can help you, actually i am using this.
