springboot调用第三方接口，实现人脸识别登录

调用第三方接口的http协议请求

import java.io.File;

/**
*人脸识别登录调用face++接口
*一般会有api key和api secret
*/
public class FaceTest {
    public static final String URL = "要配置的url";
    public static final String FILE_PATH = "D:/text.jpg";
    public static void main(String[] args) {

        RestTemplate restTemplate = new RestTemplate();

        //设置请求头
        HttpHeaders httpHeaders = new HttpHeaders();
        MediaType mediaType = MediaType.parseMediaType("multipart/form-data");
        httpHeaders.setContentType(mediaType);

        /* 设置请求体 */
        FileSystemResource fileSystemResource = new FileSystemResource(new File(FILE_PATH));
        MultiValueMap<String, Object> form = new LinkedMultiValueMap<>();
        form.add("image_best", fileSystemResource);
        form.add("image_idcard",fileSystemResource);

        //用httpEntity封装
        HttpEntity<MultiValueMap<String, Object>> multiValueMapHttpEntity = new HttpEntity<>(form, httpHeaders);

        String s = restTemplate.postForObject(URL, multiValueMapHttpEntity, String.class);
        System.out.println(s);


    }
}

公司用的自己封装了一个调用的工具类，为了自己找代码方便
