用RestTemplate调用百度文字识别接口

1. 将RestTemplate加载到bean工厂

@Configuration
public class RestTemplateConfig {
	
    private Logger logger = LogManager.getLogger(getClass());
	
    @Bean
    public RestTemplate restTemplate(ClientHttpRequestFactory factory){
		logger.debug("-----------加载RestTemplate模板----------");
        return new RestTemplate(factory);
    }
    
    @Bean
    public ClientHttpRequestFactory simpleClientHttpRequestFactory(){
        SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
        factory.setReadTimeout(5000);
        factory.setConnectTimeout(15000);
        return factory;
    }
}

2.调用接口，获取单位名称，和统一社会信用代码

//营业执照识别
 @Test
 public void businessLicenseTest() {
	 String url = "https://aip.baidubce.com/rest/2.0/ocr/v1/business_license?access_token="+access_token;
	 String image = getImage("g://picture//c2.png");
	 HttpHeaders headers = new HttpHeaders();
	 headers.add("Content-Type", "application/x-www-form-urlencoded");
	 MultiValueMap postParameters = new LinkedMultiValueMap();
	 postParameters.add("image", image);
	 HttpEntity> requestEntity = new HttpEntity>(
			 postParameters, headers);
	 String result = template.postForObject(url,requestEntity,String.class);
	 try {
		 result = new String (result.getBytes("iso-8859-1"),"utf-8");
	 } catch (UnsupportedEncodingException e) {
		 e.printStackTrace();
	 }
	 System.out.println("--------"+result);
	 printResult(result,"社会信用代码");
 }

 public void printResult(String result , String item){
	 JSONObject jsonObject = new JSONObject(result);
	 JSONObject words_result = (JSONObject)jsonObject.get("words_result");
	 JSONObject name = (JSONObject)words_result.get(item);
	 String name1 = (String)name.get("words");
	 System.err.println(item + "--" + name1);
 }
 public String getImage(String url){
	 InputStream in = null;
	 byte[] data = null;
	 //读取图片字节数组
	 try 
	 {
		 in = new FileInputStream(url);        
		 data = new byte[in.available()];
		 in.read(data);
		 in.close();
	 } 
	 catch (IOException e) 
	 {
		 e.printStackTrace();
	 }
	 String image = Base64.encode(data);
	 return image;
 }
