android - Uber无效的OAuth 2.0凭据提供Uber身份验证在android中

IM集成Uber Ride请求API。我成功地验证了uber帐户。我可以从uber api获得用户历史和用户配置文件，但我没有得到v1.2/requests/estimate，而是在我请求ride时。使用下面的代码…
我得到了回应。
{“消息”：“提供的OAuth 2.0凭据无效。”，“代码”：“未授权”}

public JSONObject getFareid(String address,String product_id,floatstart_latitude,float start_longitude,float end_latitude,floatend_longitude,String token,String scope) {
    try {

        httpClient = new DefaultHttpClient();
        httpPost = new HttpPost(address);
        params.add(new BasicNameValuePair("product_id", product_id));
        params.add(new BasicNameValuePair("start_latitude", "17.456f"));
        params.add(new BasicNameValuePair("start_longitude", "78.3755f"));
        params.add(new BasicNameValuePair("end_latitude", "17.3853f"));
        params.add(new BasicNameValuePair("end_longitude","78.404f") );
        params.add(new BasicNameValuePair("Authorization","Bearer"+token));

        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) {

    }
    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;
}

}

最佳答案

这可能是因为在头文件中的“承载者”和令牌值之间没有空格。httpPost.setHeader("Authorization","Bearer"+token);
必须Authorization: Bearer <mytoken>
更新
您正在将数据值设置为名称-值对。
如果内容类型是json，则必须设置json。
检查此答案：How to send POST request in JSON using HTTPClient?
你必须设置：

 JSONObject holder = getJsonObjectFromMap(params);

//passes the results to a string builder/entity
StringEntity se = new StringEntity(holder.toString());

//sets the post request as the resulting string
httpost.setEntity(se);
