java的httpClient类调用https接口时,可以不写SSL相关代码,直接用跟调用http接口时一样的代码吗?

最近看到代码中别人封装的http请求类,请求第三方https的接口时,没有写任何SSL相关的代码。https不是需要做SSL的操作或者进行跳过证书验证吗?但是我看代码中没有一个地方有这个操作的,而且居然还访问正常。https可以用访问http的方式访问吗?图片说明图片说明上面是他写的代码

底层有封装的 SSLSocketFactory 的实现,使用了默认的证书。

CQHasADream 我也很懵逼这种情况,为啥我也没跳过证书,访问https依然访问通了

为什么HttpClient不设置SSL也能连接带Https的网页?

是有封装了SSLSocketFactory,使用默认的证书?

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

java请求https,在本地可以,在服务器端请求失败

java请求https,在本地可以,在服务器端请求失败,是服务器端失败哦! 自己的前提是请求的url是正确的。 附上https请求代码,请大神一看: ``` public static JSONObject httpRequest(String requestUrl, String requestMethod, String outputStr) { JSONObject jsonObject = null; StringBuffer buffer = new StringBuffer(); try { // 创建SSLContext对象,并使用我们指定的信任管理器初始化 TrustManager[] tm = { new MyX509TrustManager() }; SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE"); sslContext.init(null, tm, new java.security.SecureRandom()); // 从上述SSLContext对象中得到SSLSocketFactory对象 SSLSocketFactory ssf = sslContext.getSocketFactory(); URL url = new URL(requestUrl); HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection(); httpUrlConn.setSSLSocketFactory(ssf); httpUrlConn.setDoOutput(true); httpUrlConn.setDoInput(true); httpUrlConn.setUseCaches(false); // 设置请求方式(GET/POST) httpUrlConn.setRequestMethod(requestMethod); if ("GET".equalsIgnoreCase(requestMethod)) httpUrlConn.connect(); // 当有数据需要提交时 if (null != outputStr) { OutputStream outputStream = httpUrlConn.getOutputStream(); // 注意编码格式,防止中文乱码 outputStream.write(outputStr.getBytes("UTF-8")); outputStream.close(); } // 将返回的输入流转换成字符串 InputStream inputStream = httpUrlConn.getInputStream(); InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8"); BufferedReader bufferedReader = new BufferedReader(inputStreamReader); String str = null; while ((str = bufferedReader.readLine()) != null) { buffer.append(str); } bufferedReader.close(); inputStreamReader.close(); inputStream.close(); inputStream = null; httpUrlConn.disconnect(); jsonObject = JSONObject.fromObject(buffer.toString()); } catch (ConnectException ce) { log.error("Weixin server connection timed out."); } catch (Exception e) { log.error("https request error:{}", e); } return jsonObject; } ```

jdk1.6访问https接口报错,jdk1.7访问正常,服务端jdk为1.7

jdk1.6访问https接口报错,jdk1.7访问正常,服务端jdk为1.7报错,对比正常访问密码套件不一样,可是我下载jce之后也没有用正常使用的是TLS,1.6使用的是MD5,如图:![图片说明](https://img-ask.csdn.net/upload/201901/29/1548755192_521116.jpg) ![图片说明](https://img-ask.csdn.net/upload/201901/29/1548755365_63670.png)

client调用多个不同的基于HTTPS的webservices时,System.setProperty(javax.net.ssl.XXX)不起作用?

在同一个web应用里, 作为client访问基于HTTPS的webservices,client这边通过设置以下系统参数,是可以成功的, System.setProperty("javax.net.ssl.keyStore", keystoreFile); System.setProperty("javax.net.ssl.keyStorePassword",keystorePassword); System.setProperty("javax.net.ssl.trustStore", truststoreFile); System.setProperty("javax.net.ssl.trustStorePassword",truststorePassword); 但是,现在clinet还要访问另外一个也是基于HTTPS的web services,当然证书是不一样的, 这时client能再次设置这些系统参数为另外的值么?访问能成功么? 找到之前的一个相关的帖子,好像没有结论?http://www.iteye.com/problems/9652 多谢! :) [b]问题补充:[/b] 注释掉第一次的调用,第二次的调用是成功的,所以相关参数肯定是设置对了。 但是只要运行两次调用(调不同的webservice),即使中间clearProperty,还是不行。 还尝试过颠倒两次调用的顺序,结果也总是第二次的调用不成功。 :( [b]问题补充:[/b] to pJun,System.getProperty的结果是第二次设置的值。thx [b]问题补充:[/b] 是不是不应该采取这种设置系统参数的方式啊? 有其他方法么? 8) [b]问题补充:[/b] HTTPClient能不能动态的设置keystore/keystorepasswd/truststore/truststorepasswd呢? :wink: [b]问题补充:[/b] 换了一种方式,使用了http://hc.apache.org/httpclient-3.x/sslguide.html里提供的AuthSSLProtocolSocketFactory 调用的代码也是按照其注释写的,但是感觉只是调用了一下构造函数,并没有实质的动作,调用结果也是失败的:PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 下面是代码: [code="java"] HttpClient client = new HttpClient(new MultiThreadedHttpConnectionManager()); client.getHttpConnectionManager().getParams().setSoTimeout(3000); client.getHttpConnectionManager().getParams().setMaxTotalConnections(5); Protocol authhttps = null; try { authhttps = new Protocol( "https", new AuthSSLProtocolSocketFactory( new URL( "file:/C:/Documents and Settings/test/Desktop/tmp/keystore"), "mypasswd", new URL( "file:/C:/Documents and Settings/test/Desktop/tmp/truststore"), "mypasswd"), 7743); } catch (MalformedURLException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } client.getHostConfiguration().setHost(wsHost,wsPort, authhttps); DefaultHttpMethodRetryHandler retryhandler = new DefaultHttpMethodRetryHandler( recoverTimes, true); client.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, retryhandler); PostMethod post = new PostMethod(wsURL); RequestEntity entity = new StringRequestEntity(requestXML, "text/xml", "UTF-8"); post.setRequestEntity(entity); HttpClientResponse httpClientResponse = null; try { int result = client.executeMethod(post); logger.log(Level.INFO, "result ="+ result); String responseXML = post.getResponseBodyAsString(); } catch (Exception ex) { logger.warning(ex.toString()); return; } finally { post.releaseConnection(); }[/code] JDK1.5 [b]问题补充:[/b] To lovewhzlq , //和///都试了一下,错误还是一样。 :x [b]问题补充:[/b] 最初重复设置两次系统参数时,也是抛这种类型的异常…… :? [b]问题补充:[/b] To pJun, 3个斜杠试过了,也不行。 是必须调用注册么? Protocol.registerProtocol("https", authhttps); 注不注册有区别么? 我再试试不用URL表示本地文件路径吧。。。。也许就能找到文件了。 [b]问题补充:[/b] 需要调用registerProtocol,否则AuthSSLProtocolSocketFactory不起作用。谢谢大家。

新手请教下如何实现基于国密sm2/sm3算法的SSL认证?

现在要做一个网关系统,客户端(windows系统)设一个驻留程序,可以和服务端(linux服务器)进行SSL通讯。 当客户端的应用(浏览器或其他client程序)发起登录认证、加密、签名等请求操作时,驻留程序接收到该请求,和服务端进行基于国密SM2/SM3的SSL通讯,服务端完成相应业务操作后,由驻留程序最终将服务端返回的结果送回浏览器或其他client程序。 请教下: 1、如何在原有的无SSL模块的网关系统中,集成进去 基于国密SM2/SM3的SSL模块? 2、基于国密SM2/SM3的SSL模块,有现成的开源代码吗? 谢谢谢谢! ps:如果有c的实现就更好了。

tomcat配置客户端ssl证书

jdk中的jre/lib/security目录下为啥要导入证书

之前项目中用httpclient调用第三方接口,走的是https,之前正常运行。后来测试把测试环境的jdk换成了openjdk,后运行报错 报错信息如下 ``` java.lang.RuntimeException: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty ``` 后来排查发现之前jdk的jre/lib/sercurity目录下有cer证书,而新安装的openjdk目录下没有证书,后来把jdk目录下证书拷贝到openjdk目录下,就好了。 想确认下这个证书的作用是什么。是不是可以认为就好比浏览器访问https需要导入证书。

150讲轻松搞定Python网络爬虫

【为什么学爬虫?】 &nbsp; &nbsp; &nbsp; &nbsp;1、爬虫入手容易,但是深入较难,如何写出高效率的爬虫,如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中,经常容易遇到被反爬虫,比如字体反爬、IP识别、验证码等,如何层层攻克难点拿到想要的数据,这门课程,你都能学到! &nbsp; &nbsp; &nbsp; &nbsp;2、如果是作为一个其他行业的开发者,比如app开发,web开发,学习爬虫能让你加强对技术的认知,能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序,无论大小,总体来说可以分成三个步骤,分别是: 网络请求:模拟浏览器的行为从网上抓取数据。 数据解析:将请求下来的数据进行过滤,提取我们想要的数据。 数据存储:将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解,带领学生完整的掌握每个步骤的技术。另外,因为爬虫的多样性,在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性,分别是: 爬虫进阶:包括IP代理,多线程爬虫,图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫:Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站,而Scrapy框架作为一个专业的爬虫框架,使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求,我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 &nbsp; 从基础爬虫到商业化应用爬虫,本套课程满足您的所有需求! 【课程服务】 专属付费社群+每周三讨论会+1v1答疑
