HTTPClient 发送HTTPS请求

HTTPClient 发送HTTP请求就不多说了，现在给出发送HTTPS请求，主要思路是忽略证书验证.

/** *  * @param url * @param contextType  "image/jpeg","application/Json" * @return */public static byte[] sendHttpsGetUrl(HttpClient httpClient1 ,String url,String contextType) {// 响应内容byte[] bs = null;// 创建默认的httpClient实例//HttpClient httpClient = new DefaultHttpClient();HttpClient httpClient =httpClient1;// 创建TrustManagerX509TrustManager xtm = new X509TrustManager() {public void checkClientTrusted(X509Certificate[] chain,String authType) throws CertificateException {}public void checkServerTrusted(X509Certificate[] chain,String authType) throws CertificateException {}public X509Certificate[] getAcceptedIssuers() {return new X509Certificate[] {};}};try {SSLContext ctx = SSLContext.getInstance("SSL");// 使用TrustManager来初始化该上下文，TrustManager只是被SSL的Socket所使用ctx.init(null, new TrustManager[] { xtm }, null);SSLSocketFactory sf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);Scheme sch = new Scheme("https", 443, sf);httpClient.getConnectionManager().getSchemeRegistry().register(sch);// 创建HttpPostHttpGet httpPost = new HttpGet(url); httpPost.setHeader("content-type", contextType);// 执行POST请求HttpResponse response = httpClient.execute(httpPost); // 获取响应实体HttpEntity entity = response.getEntity(); bs = IOUtils.toByteArray(entity.getContent()); if (null != entity) {EntityUtils.consume(entity); // Consume response content}return bs;} catch (Exception e) {e.printStackTrace();} finally {// 关闭连接,释放资源//httpClient.getConnectionManager().shutdown(); }return bs;}

如果连续的请求不需要带cookie，可以改造下此方法，方法参数中不带HttpClient即可，此情况下记得在爱Finally块中关闭连接。

下面给出Maven required：

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.2.3</version></dependency><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.4</version></dependency>
