从 Java 服务器（码头）发送 POST 请求

Question

我正在尝试使用参数 userId、token 和status.

在 Java 中，我正在调用以下方法：

sendNotification("https://example.com/api/test", "test1", "test", 200)

我在日志中看到它成功打印：

Sent request to https://example.com/api/test with userId test1 and token test

但是，在 https://example.com/api/test 日志中我根本没有收到任何请求。

然而，当我尝试下面的命令时，我确实收到了完美的请求：

curl -H "Content-Type: application/json" -X POST -d '{"userId": "helloo@apptium.com", "token": "asdfasdf", "status": 200}' https://example.com/api/test

怎么了？

Java方法：

private void sendNotification(String endpoint, String userId, 
                              String token, int status) throws IOException {
        URL url = new URL(endpoint);
        URLConnection con = url.openConnection();
        HttpURLConnection http = (HttpURLConnection)con;
        http.setRequestMethod("POST");
        http.setDoOutput(true);

        byte[] out = ("{\"userId\":\"" + userId + "\",\"token\":\"" + token + "\",\"status\":" + status + "}").getBytes(StandardCharsets.UTF_8);
        int length = out.length;

        http.setFixedLengthStreamingMode(length);
        http.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        http.connect();
        try {
            log.warn("Sent request to " + endpoint + " with userId " + userId + " and token " + token);
            OutputStream os = http.getOutputStream();
            os.write(out);
        }
        catch(IOException e) {
            log.error(APImessages.ERROR_500);
        }
    }

您必须调用 "os.close()" 才能完成向远程服务器发送请求正文
