Question

我正在尝试使用仅应用程序承载令牌来获取https://api.twitter.com/1.1/search/tweets.json?q=nasa&count=5的推文，该令牌已成功使用了消费者密钥和消费者秘密。但是我无法获取这些推文。这是我的代码：

public class SearchTweetsTask extends AsyncTask<String, Void, String> {

    private static final String TWITTER_HOST = "api.twitter.com";
    private static final String TWITTER_USER_AGENT = "TwitterMotion User Agent";

    private Logger logger = Logger.getLogger();

    @Override
    protected String doInBackground(String... tokens) {
        String endPointUrl = tokens[0];
        HttpsURLConnection urlConnection = null;

        try {
            urlConnection = getHTTPSConnection("GET", endPointUrl);
            urlConnection.setRequestProperty("Authorization",
                    "Bearer " + APPLICATION_ONLY_BEARER_TOKEN);


            String jsonResponse = readResponse(urlConnection);

            return responseAsJsonObject.toString();
        }
        catch (Exception ex) {
            logger.e(ex);
            return null;
        }
        finally {
            if (urlConnection != null) {
                urlConnection.disconnect();
            }
        }
    }

    @Override
    protected void onPostExecute(String asyncTaskResult) {
        logger.i(asyncTaskResult);
    }



    public static HttpsURLConnection getHTTPSConnection(String requestMethod, String endpointUrl)
            throws IOException {
        URL url = new URL(endpointUrl);
        HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setDoInput(true);
        connection.setRequestMethod(requestMethod);
        connection.setRequestProperty("Host", TWITTER_HOST);
        connection.setRequestProperty("User-Agent", TWITTER_USER_AGENT);
        connection.setUseCaches(false);
        return connection;
    }


    public static String readResponse(HttpsURLConnection connection) throws IOException {
        BufferedReader bufferedReader = null;
        try {
            StringBuilder stringBuilder = new StringBuilder();
            bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            while((line = bufferedReader.readLine()) != null) {
                stringBuilder.append(line + System.getProperty("line.separator"));
            }
            return stringBuilder.toString();
        }
        catch (IOException ex) {
            throw ex;
        }
        finally {
            if (bufferedReader != null) {
                bufferedReader.close();
            }
        }
    }
}

在readRequest()方法内部，connection对象无法正常工作。我检查了connection.getResponseCode()并返回了400，而connection.getErrorStream()返回了Error Code 86 “This method requires a GET or HEAD”。

我从命令行尝试了cURL，它运行良好。

curl -X GET \
  'https://api.twitter.com/1.1/search/tweets.json?q=nasa&result_type=popular' \
  -H 'Authorization: Bearer <Application Only Bearer Token>' \
  -H 'Cache-Control: no-cache' \
  -H 'Host: api.twitter.com' \
  -H 'User-Agent: TwitterMotion User Agent'

它变得非常令人沮丧。预先感谢！

Answer 1

如here所述，httpCon.setDoOutput(true)隐式将请求方法设置为POST，因为这是每当您要发送请求正文时的默认方法。

如果要使用GET，请删除该行。

Twitter应用程序仅身份验证-错误代码86“此方法需要GET或HEAD”
