调用流式接口

调用的API是支持stream返回的，通过此方式可以流式获取返回结果。可以适当调整chunk size

public void getAnswer(@RequestBody JSONObject params) {
    String url = wxyyService.wxyyUrl();
    String userId = String.valueOf(SecurityUtils.getUserId());
    try {
        URL apiUrl = new URL(url);
        HttpURLConnection connection = (HttpURLConnection) apiUrl.openConnection();
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setDoOutput(true);
        connection.setChunkedStreamingMode(10);
        connection.getOutputStream().write(params.toString().getBytes());

        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        while ((line = reader.readLine()) != null) {
            myWebSocketUtils.sendOneMessage(userId, line);
        }
        reader.close();
        connection.disconnect();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
