百度云ocr是国内用得比较多的第三方OCR识别API了。速度快，识别率高，支持旋转后的图片等功能深受广大码农的喜爱。今天咱们要说的是百度云OCR中的一个比较常用的识别源码：

java版的百度云ocr源码参考：

    /**
     * 身份证ocr
     * @param file 身份证正面照片文件
     * @return map
     */
    public Map<String,String> idCardOcr(MultipartFile file) throws Exception {
        Map result = new HashMap();

        JSONObject jsonObject = null;
        String filePath, fileImg = "";
        //本地图片转为base64编码
        fileImg = FileUtils.multipartFileToBASE64(file);

        Map<String,Object> params = new HashMap<>();
        params.put("image", fileImg);
        params.put("id_card_side", "front");
        Map<String, String> headers = new HashMap<>();
        headers.put("Content-Type", "application/x-www-form-urlencoded");
        String s = "";
        try {
            s = HttpUtils.httpClientPost(idCardUrlPath + getAuth(), params, "UTF-8", headers);
        } catch (Exception e){
            e.printStackTrace();
            result.put("status","false");
            result.put("result",s);
            return result;
        }
        System.err.println("百度云身份证识别结果->" + s);
        jsonObject = JSON.parseObject(s);
        if(!"normal".equals(jsonObject.getString("image_status"))){
            result.put("status","false");
            result.put("result",jsonObject.getString("image_status"));
            return result;
        }
        JSONObject words_result = jsonObject.getJSONObject("words_result");
        String address = words_result.getJSONObject("住址").getString("words");
        String id_card = words_result.getJSONObject("公民身份号码").getString("words");
        String name = words_result.getJSONObject("姓名").getString("words");
        result.put("status","true");
        result.put("address",address);
        result.put("id_card",id_card);
        result.put("name",name);
        return result;
    }
