Question

我正在集成优步乘车请求 API。我成功验证了 uber 帐户。我可以从 uber api 获取用户历史记录和用户配置文件，但我没有获取 v1.2/requests/estimate。但是当我请求乘车时。使用下面的代码......

我收到回复了。

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("end_latitude", "17.3853f"));
        params.add(new BasicNameValuePair("end_longitude","78.404f") );

        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;
}

}

这可能是因为您的 header 中的“bearer”和 token 值之间没有提供空格。 httpPost.setHeader("Authorization","Bearer"+token);

必须是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。检查这个答案: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);
