微信小程序码接口经常超时,read/connect Timed out

小程序码获取接口经常超时https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token=%s每天有几百次超时, 20000次左右调用,大概有不足500的超时 调用相关代码

SimpleClientHttpRequestFactory simpleClientHttpRequestFactory = new SimpleClientHttpRequestFactory();
simpleClientHttpRequestFactory.setConnectTimeout(3000);
simpleClientHttpRequestFactory.setReadTimeout(6000);

RestTemplate restTemplate = new RestTemplate(new BufferingClientHttpRequestFactory(simpleClientHttpRequestFactory)) ;

String url=String.format(settings.getWXaCodeUnlimit(), token);
Map<String, Object> param = new HashMap<>();
param.put("scene", sceneStr);
param.put("page", page);
param.put("width", 160);
param.put("auto_color", false);
Map<String,Object> lineColor = new HashMap<>();
lineColor.put("r", 0);
lineColor.put("g", 0);
lineColor.put("b", 0);
param.put("line_color", lineColor);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON_UTF8);

HttpEntity requestEntity = new HttpEntity(param, headers);
ResponseEntity<byte[]> entity = null;
entity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, byte[].class);

      不断了吧,一共9s呢,时间太长没有意义了,可能调用方就提前中断了

      setConnectTimeout超过三秒报connect time out.。
      setReadTimeout超过六秒报read time out。你把报错的请求时间都打印出来
