怎么使用获得的OAuth2.0 Access Token调用API

String url=" url?access_token="+access_token;

HttpGet request=new HttpGet(url);

System.out.println("保存的access_token="+access_token);HttpClient client=new GetDefaultClient().getNewHttpClient();

try{

HttpResponse response=client.execute(request);

int code=response.getStatusLine().getStatusCode();if (code == 200){

InputStream is = response.getEntity().getContent();BufferedReader reader = new BufferedReader(new InputStreamReader(is,"UTF-8"));StringBuilder buffer = new StringBuilder();try{String line;while ((line=reader.readLine())!=null){buffer.append(line);}} finally{reader.close();}String string = buffer.toString();System.out.println(string);

//return Integer.parseInt(string);

}} catch (UnsupportedEncodingException e){// TODO Auto-generated catch blocke.printStackTrace();} catch (ClientProtocolException e){// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e){// TODO Auto-generated catch blocke.printStackTrace();} }
