Uber API - requesting ride in sandbox - Receiving Error: Invalid request - validation_failed

Question

我正在使用 Uber API 并尝试在沙盒中叫车。我正在关注这里的 API 指南 - Uber API - POST Request.

StringEntity 参数； 或 JSON 如下所示：

{
"product_id": "3145c334-25c6-462d-a2f5-70c38a165746",
"start_latitude": 41.2237329,
"start_longitude ": -73.2304860,
"end_latitude": 41.7220050,
"end_longitude": -73.3159659
}

我的Java代码看起来像：

    String url = "https://sandbox-api.uber.com/v1/requests";
    HttpPost httpPostRequest = new HttpPost(url);
    httpPostRequest.setHeader("Authorization", "Bearer " + accessTokenModel.getAccess_token());
    httpPostRequest.setHeader("Content-Type", "application/json");
    httpPostRequest.setEntity(param);
    HttpResponse httpResponse = client.execute(httpPostRequest);

    response.getWriter().println("Status Code: " + httpResponse.getStatusLine().getStatusCode());

    br = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));

    line = line1 = "";
    while ((line = br.readLine()) != null) {
            response.getWriter().println(line);
            line1 = line1 + line;
    }

我收到了，状态码：422 错误说：

{"fields":{"":"Both start_latitude and start_longitude or start_place_id are required."},"message":"Invalid request","code":"validation_failed"}

我的 JSON 看起来类似于建议的 Uber 示例..我也在设置 JSON header 与 - 授权令牌和内容类型..所以不确定我错过了什么..

任何人都可以发现 - 我做错了什么吗？

提前致谢

start_longitude 字段名称后附加了一个空白字符：

"start_longitude "
                ^ remove this space character
