在阿里云官网，申请一个token

[阿里官方]身份证OCR文字识别_API专区_云市场-阿里云 (aliyun.com)

观察一下post请求body部分json字符串，我们根据这个创建一个java对象

先默认是人像面

java 复制代码

public class IdentityBody {
    public String image;

    class configure {
        public String side = "face";
        public boolean quality_info;
    }
}

java 复制代码

@Autowired
    private OkHttpClient okHttpClient;
    
    @Autowired
    private ObjectMapper objectMapper;
    
    private String cardPath = "D:\\image\\card1.jpg";
    
    private String appcode = "c8518f45d5334300b73c638e299820ab";

    public String getIdentityData() throws IOException {
        IdentityBody identityBody = new IdentityBody();
        identityBody.image = ImageToBase64.imageToBase64(cardPath);
        RequestBody requestBody = RequestBody.create(objectMapper.writeValueAsString(identityBody),
                MediaType.get("application/json; charset=utf-8"));
        Request request = new Request.Builder()
                .url("https://cardnumber.market.alicloudapi.com/rest/160601/ocr/ocr_idcard.json")
                .addHeader("Authorization", "APPCODE " + appcode)
                .addHeader("Content-Type", "application/json; charset=UTF-8")
                .post(requestBody)
                .build();

        try (Response response = okHttpClient.newCall(request).execute()) {
            if (!response.isSuccessful()) {
                String errorBody = response.body().string();
                throw new IOException(
                        "API请求失败:\n" +

            }

            String ret = response.body().string();
            System.out.println("识别结果: " + ret);
            return ret;
        }
    }
