java以get方式请求第三方接口传参json字符串

用postman请求成功的

**

DefaultAsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient();
        SheBeiGuanLiEntity obList =  shbList.get(0);
        Map params = new HashMap<>();
        params.put("deviceId", obList.getShexiangtoutongdaoid());//json里需要传的参数
        
        params.put("channelId", obList.getShexiangtoutongdaoid());

        Request r = new RequestBuilder()
                .setUrl(url)//请求的url
                .setBody(JSONObject.toJSONString(params))
                .addHeader("Content-Type", "application/json")
                .build();
        ListenableFuture future = asyncHttpClient.executeRequest(r);

        Response response = null;
        try {
            response = future.get();
        } catch (Exception e) {
            log.error("视频地址获取报错:"+e.getMessage());
            return ResponseData.error(1009, "视频请求失败");
        }
        String tempUrl = response.getResponseBody();
        //取出
        JSONObject jsonObject = JSONObject.parseObject(tempUrl).getJSONObject("data");
        String fmp4 = jsonObject.getString("fmp4");
        asyncHttpClient.close();
