帶有JSON主體的POST REST API調用在Java的播放框架中不起作用

Question

我無法使用Java在播放框架中調用API調用。 代碼看起來不錯，但是API調用未觸發（在Postman中，API調用工作正常）。 我認為這可能是與線程相關的問題，我無法在play框架中編寫異步任務，請有人幫我。 希望最好！ 提前致謝！

在控制器文件中找到API調用的代碼

public Result updateTripDetail() {
//few statements;
            String url = "https://medicines-XXX/MZIMRestServicesXXX/v1/XXXX";
            JSONObject jsonBody = new JSONObject();
            jsonBody.put("source_type", "XXX");
            jsonBody.put("omorder_id", "25852");
            if (Rescheduled.equals(ride.getRideStatus())) {
                jsonBody.put("order_status", "RequestForReschedule");
            } else if (RideCancelled.equals(ride.getRideStatus())) {
                jsonBody.put("order_status", "RequestForCancel");
            } else {
                jsonBody.put("order_status", ride.getRideStatus());
            }
            jsonBody.put("last_updated_on", new Date());
            apiPostCall(url,jsonBody.toString());
    return redirect("/ride/rideList");
}

public void apiPostCall(String completeUrl, String body) {
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(completeUrl);
    httpPost.setHeader("Content-type", "application/json");
    try {
        StringEntity stringEntity = new StringEntity(body);
        httpPost.getRequestLine();
        httpPost.setEntity(stringEntity);
        httpClient.execute(httpPost);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

顯然，您沒有在HTTP請求中使用播放命令。 您的代碼應如下所示：

public void updateTripDetail() {
//few statements;
            String url = "https://medicines-XXX/MZIMRestServicesXXX/v1/XXXX";
            JSONObject jsonBody = new JSONObject();
            jsonBody.put("source_type", "XXX");
            jsonBody.put("omorder_id", "25852");
            if (Rescheduled.equals(ride.getRideStatus())) {
                jsonBody.put("order_status", "RequestForReschedule");
            } else if (RideCancelled.equals(ride.getRideStatus())) {
                jsonBody.put("order_status", "RequestForCancel");
            } else {
                    jsonBody.put("order_status", ride.getRideStatus());
                }
                jsonBody.put("last_updated_on", new Date());
                apiPostCall(url,jsonBody.toString());
        //As an asynchronous request it would 
        //probably redirect before completing your request so void it's okay
        //return redirect("/ride/rideList");
    }

public Promise<Result> apiPostCall(String completeUrl, String body) {
        return WS.url(completeUrl)
                .setHeader("Content-Type", "application/json")
                .post(body).map(
                        new F.Function<WS.Response, Result>() {
                            public Result apply(WS.Response response) {
                                //you can handle your response here
                                //String token = response.asJson().findPath("access_token").asText();
                                return redirect("/ride/rideList");
                            }
                        }
                );
    }
