关于httpclient4.5的问题-CSDN问答

关于httpclient4.5的问题: 在 httpclient 3 里面 get和post方法都可以用HttpMethod 类来表示然后传入一个函数，而4.5中没有HttpMethod这个类，那么这两个方法可以用哪个类来表示呢，借此来传入一个函数，HttpUriRequest类可以吗？; 发布于：2016.08.04 09:05

HttpClient4.5.2获取cookieStore问题: 大神们好，现在apache版本升级，以前的DefaultHttpClient 可以直接获取cookiestore信息，升级4.5后换成了closeableHttpClient, 没有获取相应的方法了。有什么思路可以获取么？帮忙看下

httpclient4.5请求jsp时jsp上的jstl标签<fmt:formatDate>不会格式化日期: httpclient4.5请求jsp时jsp上的jstl标签fmt:formatDate不会格式化日期，浏览器访问相同url能正常格式化日期。 jsp代码 ``` <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %> ..... <% Date iDate = new Date(); request.setAttribute("iDate", iDate); %> <div> <c:forEach var="v" begin="1" end="3" step="1"> <div> <fmt:formatNumber value="${v}" pattern="####.00" /> </div> </c:forEach> </div> <div> =[fmt]<fmt:formatDate value="${iDate}" pattern="yyyy-MM-dd" /> </div> <div> =[native]${iDate } </div> ``` 浏览器正常 ``` <DIV>1.00 </DIV> <DIV>2.00 </DIV> <DIV>3.00 </DIV> <DIV>=[fmt]**2015-07-14**</DIV> <DIV>=[native]Tue Jul 14 22:28:17 CST 2015 </DIV> ``` httpclient4.5访问时返回不正确 ``` <div>1</div> <div>2</div> <div>3</div> <div>=[fmt]**Tue Jul 14 23:03:57 CST 2015**</div> <div>=[native]Tue Jul 14 23:03:57 CST 2015</div> ``` jstl应该是在服务器生成html文本返回客户端前执行的，c:foreach之类的可以，fmt:xxxx之类的标签却不能正确执行。

httpclient4.5访问网页时报Cookie rejected: httpRequestBase.setHeader("User-Agent", "Mozilla/5.0"); httpRequestBase.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"); httpRequestBase.setHeader("Accept-Language", "zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3");// "en-US,en;q=0.5"); httpRequestBase.setHeader("Accept-Charset", "ISO-8859-1,utf-8,gbk,gb2312;q=0.7,*;q=0.7"); httpRequestBase.setHeader("Cookie", "**********“）；加了最后这一会也不好使，求大神~

HttpClient升级4.5.2问题: 大神们好：最近羡慕中升级htpclient版本，有的代码不知道怎么改，新版本的方法已经不建议使用，因为用了最新的httpclient连接池，所有有的方法不改就报错，代码如下，实在没有找到替代方法。![图片说明](https://img-ask.csdn.net/upload/201610/24/1477296022_354133.png)

httpclient-4.5.2读取超时，重发没起到作用，为什么？: 1、写了一个httpclient的工具类，也写了重试的逻辑，但是在多个线程在使用同一个httpclient实例的时候，发现线程read time out的超时并没有被重发很郁闷(线程直接进入的SocketTimeoutException异常，导致本次线程的请求没有拿到再次重发后的结果，导致数据丢失） public CloseableHttpClient getHttpClient() { return HttpClients.custom(). setConnectionManager(connMrg). setKeepAliveStrategy(myStrategy). setDefaultRequestConfig(requestConfig). setConnectionManagerShared(true). setMaxConnTotal(maxTotal). setRetryHandler( new HttpRequestRetryHandler() { @Override public boolean retryRequest(IOException exception , int executionCount , HttpContext context) { // 重试3次,从3开始 if (executionCount > 3) { return false; } /* if (exception instanceof NoHttpResponseException) { System.out.println( "[NoHttpResponseException has retry request:" + context.toString() + "][executionCount:" + executionCount + "]"); return true; } else if (exception instanceof SocketException || exception instanceof ConnectTimeoutException || exception instanceof SocketTimeoutException ) { System.out.println("[SocketException has retry request:" + context.toString() + "][executionCount:" + executionCount + "]"); return true; } */ if (exception instanceof UnknownHostException) { return false; } // SSL handshake exception if (exception instanceof SSLException) { return false; } //除上述两种异常其他异常均重试3次，其实主要问题在于 //服务端对连接数限制，会导致你再怎么重试，都会异常，连接数满了，重试还有毛用 //所以设置连接池的时候需要设置的比他们的最大值小，用完要及时释放到连接池 String time3 = new SimpleDateFormat("HH:mm:ss.SSS").format(new Date()); System.out.println("time:"+time3+"="+Thread.currentThread().getName() +"\n"+"[Exception:"+exception.toString()+" has retry request:" + context.toString() + "][executionCount:" + executionCount + "]"); return true; } } ). build(); } 问题3： String time3 = new SimpleDateFormat("HH:mm:ss.SSS").format(new Date()); System.out.println("time:"+time3+"="+Thread.currentThread().getName() +"\n"+"[Exception:"+exception.toString()+" has retry request:" + context.toString() + "][executionCount:" + executionCount + "]"); return true; 这段代码发生read time out的时候执行了，但是executionCount一直都是1，我理解应该是重发了一次，但是子线程里的日志打印了异常，并没有获取到重试后的结果问题4，子线程取数据逻辑，只写了主要逻辑 httpPost.setHeader("Content-Type", "text/xml;charset=UTF-8"); // httpPost.setHeader("SOAPAction", ""); StringEntity data = new StringEntity(inputPara, Charset.forName("UTF-8")); httpPost.setEntity(data); try { response = httpClient.execute(httpPost); httpEntity = response.getEntity(); if (httpEntity != null) { // 获取响应内容 returnVal = EntityUtils.toString(httpEntity, "UTF-8"); // 消费掉节约内存,并关闭inputstream流 EntityUtils.consume(httpEntity); } } catch (Exception e) { e.printStackTrace(); } finally { try { // 关闭流并释放资源 response.close(); } catch (Exception e) { e.printStackTrace(); } } 我认为在这段的httpEntity = response.getEntity();执行的时候 readtime out，然后代码直接进入了catch逻辑，所以重发后的结果并没有取到。问题5： 1、我就是想解决，读取超时就重发，一直到3次结束。 2、是不是我设置的读取超时时间为60s导致根本没办法重发，服务端可能已经把短连接关闭了因为http默认短连接时间好像就是60s。我猜测，如果我设置读取时间为10s，可能就可以重试3次了。 3、 try{ httpEntity = response.getEntity(); } catch() { } 这段逻辑跟创建httpclient的方法里面的重试方法，当发生异常时，到底是这段阻塞httpEntity = response.getEntity(); 等待3次重发？还是是异步的，里面重发，外面直接进入异常逻辑，根本不等重发后的结果

.Net FW4.0的HttpClient疑似bug问题怎么解决?: 使用HttpClient.SendAsync时,request实参中的Uri斜杠('/')被Url解码导致请求Url错误,返回404,如何防止这种解码? 4.5已经试过没有这个问题. 以下是代码片段: ``` apiClient = new HttpClient {BaseAddress = new Uri("http://...")}; ``` ``` var request = new HttpRequestMessage(HttpMethod.Post, "accessToken/getAccessToken"); request.AddMatrixParam(new Dictionary<string, string> { ["encryptStr"] = encryptStr, ["timestamp"] = timestamp.ToString() }); ``` AddMatrixParam方法是将字典转化为Matrix格式的url参数,然后拼接到url上,这个方法的操作结果确认没有问题 ``` Debug.WriteLine($"Request URL: {request.RequestUri}"); var response = apiClient.SendAsync(request).Result; Debug.WriteLine($"Request URL: {request.RequestUri}"); ``` 输出: > Request URL: accessToken/getAccessToken;encryptStr%3dPoB3dUXFGAaN3ZEcovdYgBp6GSu6ECvqIaSPvLgEWp5Ml%2fAkD5sbqWlqUTcqUoV0CTU3%2b%2bUvVYA%2f94bjj%2fAHv%2bXnFRIT8xjFCiKgLG94sx8%3d%3btimestamp%3d1565949032 > Request URL: http://.../accessToken/getAccessToken;encryptStr=PoB3dUXFGAaN3ZEcovdYgBp6GSu6ECvqIaSPvLgEWp5Ml/AkD5sbqWlqUTcqUoV0CTU3++UvVYA/94bjj/AHv+XnFRIT8xjFCiKgLG94sx8=;timestamp=1565949032 请求发送前后的相对url部分是不一样的,"/"被莫名其妙得解码了出来

线程一直处于RUNNABLE，也没有发现阻塞或是死锁的情况？: 我写的是一个频繁访问网络的爬虫，启了20个线程；但是老实跑了一段时间，线程全部处于RUNNABLE状态了；网络使用的是httpclient3.1; 我把threaddump给放到下面： ``` "Thread-19" #30 prio=5 os_prio=0 tid=0x0000000059b3d000 nid=0xcb4 runnable [0x000000005ba1e000] java.lang.Thread.State: RUNNABLE at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:150) at java.net.SocketInputStream.read(SocketInputStream.java:121) at java.io.BufferedInputStream.fill(BufferedInputStream.java:246) at java.io.BufferedInputStream.read(BufferedInputStream.java:265) - locked <0x0000000086f05c90> (a java.io.BufferedInputStream) at org.apache.commons.httpclient.HttpParser.readRawLine(HttpParser.java:78) at org.apache.commons.httpclient.HttpParser.readLine(HttpParser.java:106) at org.apache.commons.httpclient.HttpConnection.readLine(HttpConnection.java:1116) at org.apache.commons.httpclient.HttpMethodBase.readStatusLine(HttpMethodBase.java:1973) at org.apache.commons.httpclient.HttpMethodBase.readResponse(HttpMethodBase.java:1735) at org.apache.commons.httpclient.HttpMethodBase.execute(HttpMethodBase.java:1098) at org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(HttpMethodDirector.java:398) at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(HttpMethodDirector.java:171) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:397) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:323) at com.uzons.domain.search.v2.searcher.EBChecker.validate(EBChecker.java:34) at com.uzons.domain.search.v2.taskscheduler.DomainJob.exec(DomainJob.java:28) at com.uzons.domain.search.v2.taskscheduler.DomainScheduler.execute(DomainScheduler.java:110) at com.uzons.domain.search.v2.taskscheduler.DomainScheduler.run(DomainScheduler.java:92) Locked ownable synchronizers: - None ```

问下httpclient怎么能对服务端进行断点调试: 我是用httpclient4.5写的客户端和服务端进行交互，但是客户端的statusCode老是报500，估计是服务端代码出错了，但是不知道怎么能通过运行客户端代码对服务端进行断点调试有没有会的啊。或者有其他的办法也行

CloseableHttpClient 4.5.2如何设置等待超时?: CloseableHttpClient 4.5.2中执行response = httpClient.execute(httpPost); 没有任何的等待效果,直接返回无连接,如果我想让他保持请求30秒是否可以? ``` RequestConfig defaultRequestConfig = RequestConfig.custom(). setConnectTimeout(30000).setConnectionRequestTimeout(30000) .setSocketTimeout(30000).build(); // CloseableHttpClient httpClient = HttpClients.createDefault(); CloseableHttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig).build(); CloseableHttpResponse response = null; String resultString = ""; HttpPost httpPost = new HttpPost(url); StringEntity entity = new StringEntity(json, ContentType.APPLICATION_JSON); httpPost.setEntity(entity); httpPost.setConfig(defaultRequestConfig); String uuid=UuidUtil.getuuid(); PgmsDao pgms=new PgmsDao(); LoginUI login=(LoginUI) FacesUtil.getSessionMapValue("loginUI"); String netid=login.getLdapuser().getNetid(); String request_user=login.getLdapuser().getName(); SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String request_date = sdf.format(new Date()); Map<String,String> request_map=(Map)new JSONObject().fromObject(json); String action=request_map.get("action"); response = httpClient.execute(httpPost); resultString = EntityUtils.toString(response.getEntity(), "utf-8"); String response_date = sdf.format(new Date()); Map<String,String>result=(Map)new JSONObject().fromObject(resultString); String status=result.get("status"); ``` 如果是别的版本也可以,请大佬指点

Java项目开启https双向认证，服务中使用restTemplate发出的请求，怎么能访问该服务？: 使用https的单向认证，通过配置下面代码能实现restTemplate的访问 ``` @Primary @Bean public RestTemplate restTemplate() { return new RestTemplate(generateHttpsRequestFactory()); } public HttpComponentsClientHttpRequestFactory generateHttpsRequestFactory() { try { TrustStrategy acceptingTrustStrategy = (x509Certificates, authType) -> true; SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build(); SSLConnectionSocketFactory connectionSocketFactory = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier()); HttpClientBuilder httpClientBuilder = HttpClients.custom(); httpClientBuilder.setSSLSocketFactory(connectionSocketFactory); CloseableHttpClient httpClient = httpClientBuilder.build(); HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(); factory.setHttpClient(httpClient); factory.setConnectTimeout(10 * 1000); factory.setReadTimeout(30 * 1000); return factory; } catch (Exception e) { throw new RuntimeException("创建HttpsRestTemplate失败", e); } } ``` 如果在tomcat中开启双向https认证，访问报错 ``` org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://127.0.0.1:9082/portal/oauth/token": Received fatal alert: bad_certificate;
