Https接口调用问题

使用场景: 因为项目需要爬点接口数据, 接口是https, 在网上找的笔记整理了一下. 仅供参考

1. 调用Https的Get方法
/*** 只需要url** @param url* @return*/public static String doGetForHTML(String url) {return doGetForHTML(url, null);}/*** @param url      请求地址* @param paramMap 请求参数* @return 返回html*/public static String doGetForHTML(String url, Map<String, String> paramMap) {// 创建Httpclient对象String result = "";CloseableHttpClient httpClient = null;CloseableHttpResponse response = null;try {httpClient = getPassSSLCloseableHttpClient();URIBuilder builder = new URIBuilder(url);if (paramMap != null) {for (String key : paramMap.keySet()) {builder.addParameter(key, paramMap.get(key));}}URI uri = builder.build();//创建GET请求HttpGet httpGet = new HttpGet(uri);String userAgent = getOneUserAgent();httpGet.setHeader("User-Agent", userAgent);System.out.println(userAgent);//发送请求response = httpClient.execute(httpGet);//判断响应状态if (response.getStatusLine().getStatusCode() == 200) {result = EntityUtils.toString(response.getEntity(), "UTF-8");}} catch (Exception e) {e.printStackTrace();} finally {try {if (response != null) response.close();if (httpClient != null) httpClient.close();} catch (IOException e) {e.printStackTrace();}}return result;}
2. 调用Https的Post方法
    /*** 发送POST方式请求** @param url* @param paramMap* @return* @throws IOException*/public static String doPost4Json4Html(String url, Map<String, String> paramMap) {// 创建Httpclient对象CloseableHttpClient httpClient;CloseableHttpResponse response = null;String resultString = "";String userAgent = getOneUserAgent();try {httpClient = getPassSSLCloseableHttpClient();// 创建Http Post请求HttpPost httpPost = new HttpPost(url);if (paramMap != null) {//构造json格式数据JSONObject jsonObject = new JSONObject();for (Map.Entry<String, String> param : paramMap.entrySet()) {jsonObject.put(param.getKey(), param.getValue());}StringEntity entity = new StringEntity(jsonObject.toString(), "utf-8");//设置请求编码entity.setContentEncoding("utf-8");//设置数据类型entity.setContentType("application/json");httpPost.setEntity(entity);
//                String userAgent = getOneUserAgent();httpPost.setHeader("User-Agent", userAgent);}httpPost.setConfig(builderRequestConfig());// 执行http请求response = httpClient.execute(httpPost);resultString = EntityUtils.toString(response.getEntity(), "UTF-8");} catch (Exception e) {log.error("post请求执行异常,异常URl{},异常参数{}", url, paramMap);} finally {try {if (response != null)response.close();} catch (IOException e) {e.printStackTrace();}}return resultString;}
3. 信任所有的整数
    /*** 信任所有的证书** @return* @throws NoSuchAlgorithmException* @throws KeyManagementException*/private static CloseableHttpClient getPassSSLCloseableHttpClient() throws NoSuchAlgorithmException, KeyManagementException {// 创建信任所有证书的 TrustManagerTrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {public X509Certificate[] getAcceptedIssuers() {return null;}public void checkClientTrusted(X509Certificate[] certs, String authType) {}public void checkServerTrusted(X509Certificate[] certs, String authType) {}}};// 获取 SSL 上下文SSLContext sc = SSLContext.getInstance("SSL");sc.init(null, trustAllCerts, new java.security.SecureRandom());// 将默认的 SSLSocketFactory 和 HostnameVerifier 替换为信任所有证书的版本return HttpClients.custom().setSSLContext(sc).setSSLHostnameVerifier(new NoopHostnameVerifier()).build();}
4. 获取userAgent
/*** 随机获取一个UserAgent** @return userAgent*/
private static String getOneUserAgent() {String[] arr = getUserAgent();return arr[(int) (arr.length * Math.random())];
}/*** 防止服务器限制: 使用不同的User-Agent模拟多种浏览器发送请求* User-Agent** @return User-Agent*/private static String[] getUserAgent() {return new String[]{"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36 OPR/26.0.1656.60","Opera/8.0 (Windows NT 5.1;
