Question

我制作了一个简单的移动（Android）应用和网络（Play 2.1.0）应用。这实际上是Android上的一个傻瓜游戏，你可以在网络应用上发布你的分数（当然还要获得前10名的分数）。

因此，GET最高分数请求和POST请求都在本地（在我的计算机上）完美无瑕地工作。但是当我在Heroku上推送我的应用程序时，只有GET最高分要求工作。正如我所注意到的，POST请求的问题在于接收JSON的web api（Play2）控制器（来自Android）。我想它不知道如何从请求中解析Json ......

我使用这种方式处理Json请求：http://www.playframework.com/documentation/2.1.0/JavaJsonRequests

我修改了我的代码以找到问题：

@BodyParser.Of(BodyParser.Json.class)
public static Result newScore() {
    JsonNode json;
    try {
        json = request().body().asJson();
        String jsonString = json.toString();
        return ok(jsonString);
    } catch (Exception e1) {
        return ok("PROBLEM");
    } 
}

localhost上的响应是我发送的json字符串。 Heroku上的响应是使用String PROBLEM捕获的异常。这是一个非常奇怪的问题，我不知道为什么它在localhost上运行正常，但在heroku上却没有...任何想法？：）

解：好的，我解决了一个问题 - 这实际上是我的Android代码中的一个问题：

public void postData(String url,JSONObject obj) {
        HttpParams myParams = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(myParams, 10000);
        HttpConnectionParams.setSoTimeout(myParams, 10000);
        HttpClient httpclient = new DefaultHttpClient();

        try {
            HttpPost httppost = new HttpPost(url.toString());
            httppost.setHeader("Content-type", "application/json");

            StringEntity se = new StringEntity(obj.toString());
            //se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); // <-- PROBLEM
            httppost.setEntity(se); 

            HttpResponse response = httpclient.execute(httppost);
            String temp = EntityUtils.toString(response.getEntity());
            Log.i(TAG, temp);
        } 
        catch (ClientProtocolException e) {Log.e(TAG, "Client protocol ex");} 
        catch (IOException e) {Log.e(TAG, "io ex");}
    }

此代码现在有效，我评论了有问题的部分：将BasicHeader设置为字符串实体。对于localhost来说，这显然不是问题，但它适用于Heroku。
