OCR识别测试demo

OCR测试类：

/**
     * 测试ocr识别
     */
    @Test
    public void testOcr() {

        byte[] imageBytes = new byte[0];
        try {
            // 获取文件字节数组
            imageBytes = DownLoadPicUtil.readFileByBytes("d:\\image\\1.jpg");
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 获取百度ocr客户端
        AipOcr client = BaiduOcrUtils.getAipOcr();
        // ocr识别
        JSONObject response = client.basicGeneral(imageBytes, new HashMap<String, String>());
        JSONArray jsonArray = response.getJSONArray("words_result");
        System.out.println(jsonArray.toString());
    }

读取本地文件为byte数组：

public static byte[] readFileByBytes(String filePath) throws IOException {
        File file = new File(filePath);
        if(!file.exists()) {
            throw new FileNotFoundException(filePath);
        } else {
            ByteArrayOutputStream bos = new ByteArrayOutputStream((int)file.length());
            BufferedInputStream in = null;

            try {
                in = new BufferedInputStream(new FileInputStream(file));
                short bufSize = 1024;
                byte[] buffer = new byte[bufSize];
                boolean len = false;
                int len1;
                while(-1 != (len1 = in.read(buffer, 0, bufSize))) {
                    bos.write(buffer, 0, len1);
                }

                byte[] var7 = bos.toByteArray();
                return var7;
            } finally {
                try {
                    if(in != null) {
                        in.close();
                    }
                } catch (IOException var14) {
                    var14.printStackTrace();
                }
                try {
                    if(bos != null) {
                        bos.close();
                    }
                } catch (IOException var14) {
                    var14.printStackTrace();
                }

            }
        }
    }
