错误：Attempted read from closed stream尝试读取关闭的流！！！

原因：一个HttpClient里只能有一次获取Entity的操作，不能有多次获取Entity的操作，getEntity()获取的流是一次性的，用了一次就会自动关闭，第二次调用的时候就是调一个关闭的流，就会抛出：Attempted read from closed stream;

解决办法：如果一个方法只对同一个Entity操作，可以用BufferedHttpEntity，可以多次读取流！

HttpEntity entity = httpResponse.getEntity();if (!Objects.isNull(entity)) {try {//entity实体流保存缓冲区,否则只能操作一次流就会关闭 ,BufferedHttpEntity可以多次读取流entity = new BufferedHttpEntity(entity);responseBody = URLEncodedUtils.parse(entity).toString();} catch (IOException e) {e.printStackTrace();LogUtils.error(e, log, "io转换错误");}}

如果一个方法只对不同一个Entity操作，可以用一个临时的变量接收获取的Entity,再用临时变量走后续的逻辑！！！

这是没用临时变量接收之前，运行报错：Attempted read from closed stream

private static String getRemoteCallLogStr(HttpUriRequest httpUriRequest, HttpResponse httpResponse, long start, String method, Exception ex, String siteName) {String startTime = DateFormatUtils.format(new Date(start), "yyyy-MM-dd'T'HH:mm:ss.SSS");String path = "";String targetUrl = "";String uri = "";String targetHost = "";String requestheader = "";String responseHeader = "";String responseBody = "";Integer responseStatus = null;if (!Objects.isNull(httpUriRequest)) {if (!Objects.isNull(httpUriRequest.getURI())) {path = httpUriRequest.getURI().getPath();targetUrl = httpUriRequest.getURI().toString();targetHost = httpUriRequest.getURI().getHost();uri = httpUriRequest.getURI().toString();}requestheader = JSON.toJSONString(httpUriRequest.getAllHeaders());}if (!Objects.isNull(httpResponse)) {if (!Objects.isNull(httpResponse.getStatusLine())) {responseStatus = httpResponse.getStatusLine().getStatusCode();}HttpEntity entity = httpResponse.getEntity();if (!Objects.isNull(entity)) {try {responseBody = URLEncodedUtils.parse(entity).toString();System.out.println(responseBody);} catch (IOException e) {LogUtils.error(e, log, "io转换错误");}}responseHeader = JSON.toJSONString(httpResponse.getAllHeaders());}RemoteCallLog content = RemoteCallLog.builder().type("remote").loggerName(HttpsUtils.class.getName()).level(ex == null ? "INFO" : "ERROR").logId(LogUtils.getLogId()).time(startTime).hostName(EnvironmentUtil.getHostName()).targetMethod(path).targetUrl(targetUrl).requestId(LogUtils.initRequestIdIfAbsent()).uri(uri).requestMethod(method).status(ex == null ? "success" : "fail").duration(System.currentTimeMillis() - start).requestHeader(requestheader).responseBody(responseBody).responseHeader(responseHeader).stackTrace(ex == null ? "" : ExceptionUtils.getFullStackTrace(ex)).build();if ("POST".equals(method)) {content.setTargetSystem(siteName);} else {content.setTargetSystem(targetHost);}if (!Objects.isNull(responseStatus)) {content.setResponseStatus(responseStatus);}if ("GET".equals(method) && !Objects.isNull(httpUriRequest) && !Objects.isNull(httpUriRequest.getURI())) {content.setRequestUrlParam(httpUriRequest.getURI().getQuery());} else {HttpPost httpPost = (HttpPost) httpUriRequest;HttpEntity entity =  httpPost.getEntity();try {content.setRequestBodyParam(URLEncodedUtils.parse(entity).toString());System.out.println(content.getRequestBodyParam());} catch (IOException e) {LogUtils.error(e, log, "io转换错误");e.printStackTrace();}}return JSONObject.toJSONString(content);}

加了临时变量之后，就没有抛：Attempted read from closed stream！

HttpEntity temp=null;
HttpEntity entity = httpResponse.getEntity();
temp=entity;
if (!Objects.isNull(entity)) {try {responseBody = URLEncodedUtils.parse(temp).toString();} catch (IOException e) {e.printStackTrace();LogUtils.error(e, log, "io转换错误");}
}

HttpEntity requestTemp=null;
HttpPost httpPost = (HttpPost) httpUriRequest;
HttpEntity entity =  httpPost.getEntity();
requestTemp=entity;
try {content.setRequestBodyParam(URLEncodedUtils.parse(requestTemp).toString());
} catch (IOException e) {e.printStackTrace();LogUtils.error(e, log, "io转换错误");
}
