身份证识别接口编写的JAVA调用示例身份证识别接口编写的JAVA调用

此java文章是基本聚合数据证件识别接口来演示，基本HTTP POST请求上传图片并接收JSON数据来处理。
使用前你需要通过
https://www.juhe.cn/docs/api/id/153
申请一个名片识别的appkey
1.支持的证件类型清单
请求地址:http://api2.juheapi.com/cardrecon/supportlist?key=您申请的appkey
此接口可通过GET请求得到结果,java网络请求有HttpClient相关工具包及HttpURLConnection相关的包等，这里用的是HttpClient，需要先导包，如果用maven话会更方便直接把:

org.apache.httpcomponents httpmime 4.3.6 org.apache.httpcomponents httpclient 4.4.1

复制到配置文件 pom.xml
请求代码如下：

public static String get() throws IOException { // 创建HttpClient对象 CloseableHttpClient httpClient = HttpClients.createDefault(); CloseableHttpResponse response = null; String result = null; try { HttpGet httpGet = new HttpGet("http://api2.juheapi.com/cardrecon/supportlist?key="+ appKey); // 执行网络请求 response = httpClient.execute(httpGet); // 获取请求实体 HttpEntity resEntity = response.getEntity(); if (resEntity != null) { // ConverStreamToString是下面写的一个方法是把网络请求的字节流转换为utf8的字符串 result = ConvertStreamToString(resEntity.getContent(), "UTF-8"); } EntityUtils.consume(resEntity); } catch (Exception e) { } finally { // 关闭请求 response.close(); httpClient.close(); } // 得到的是JSON类型的数据需要第三方解析JSON的jar包来解析 return result; }

【身份证识别接口编写的JAVA调用示例】2.证件图片识别
请求地址:http://api2.juheapi.com/cardrecon/upload

// 此方法是POST请求上传的参数中包含本地图片信息File类型 public static String post(String type, File file) throws Exception { CloseableHttpClient httpClient = HttpClients.createDefault(); CloseableHttpResponse response = null; String result = null; // HttpClient请求的相关设置，可以不用配置，用默认的参数，这里设置连接和超时时长(毫秒) RequestConfig config = RequestConfig.custom().setConnectTimeout(30000).setSocketTimeout(30000).build(); try { HttpPost httppost = new HttpPost("http://api2.juheapi.com/cardrecon/upload"); // FileBody封装File类型的参数 FileBody bin = new FileBody(file); // StringBody封装String类型的参数 StringBody keyBody = new StringBody(key, ContentType.TEXT_PLAIN); StringBody typeBody = new StringBody(type, ContentType.TEXT_PLAIN); // addPart将参数传入，并指定参数名称 HttpEntity reqEntity = MultipartEntityBuilder.create() .addPart("pic", bin).addPart("key", keyBody) .addPart("cardType", typeBody).build(); httppost.setEntity(reqEntity); httppost.setConfig(config); // 执行网络请求并返回结果 response = httpClient.execute(httppost); HttpEntity resEntity = response.getEntity(); if (resEntity != null) { result = ConvertStreamToString(resEntity.getContent(), "UTF-8"); } EntityUtils.consume(resEntity); } finally { response.close(); httpClient.close(); } // 得到的是JSON类型的数据需要第三方解析JSON的jar包来解析 return result; }// 此方法是把传进的字节流转化为相应的字符串并返回，此方法一般在网络请求中用到 public static String ConvertStreamToString(InputStream is, String charset) throws Exception { StringBuilder sb = new StringBuilder(); try (InputStreamReader inputStreamReader = new InputStreamReader(is,charset)) { try (BufferedReader reader = new BufferedReader(inputStreamReader)) { String line = null; while ((line = reader.readLine()) != null) { sb.append(line).append("\r\n"); } } } return sb.toString(); }
