从必应搜索中获取搜索结果

Question

尝试使用以下代码获取搜索结果，但始终获取Bad Request。

这里是代码。

String BingURL = "https://api.datamarket.azure.com/Bing/Search/v1/News?Query=%27"+ City_Name.replace(" ","%20") +"%27";
            String accountKey = "abcdefghijklmnopqrstuvwxyz";
            HttpClient client = new DefaultHttpClient();
            try
            {
                HttpGet request = new HttpGet(BingURL);
                byte[] accountKeyBytes = Base64.encode((accountKey +":" + accountKey).getBytes(), Base64.DEFAULT);
                String accountKeyEnc = new String(accountKeyBytes);
                request.setHeader("Authorization", "Basic "+accountKeyEnc);
                ResponseHandler<String> responseHandler2 = new BasicResponseHandler();
                String responseBody = client.execute(request, responseHandler2);
                response[0] = responseBody;
                Log.v("Bing Results", responseBody);
            }

            catch(Exception e)
            {
                e.printStackTrace();
            }

这是 Logcat 的输出

有人可以建议怎么做吗？

最后，下面的代码对我有用。

byte[] accountKeyBytes = Base64.encode((accountKey + ":" + accountKey).getBytes(), Base64.NO_WRAP);
