此接口為每天100次免費(fèi)，應(yīng)對(duì)平時(shí)自己調(diào)試使用也夠了~
親測(cè)準(zhǔn)確度還不錯(cuò)。

請(qǐng)求地址

請(qǐng)求參數(shù)

請(qǐng)求結(jié)果參數(shù)說明

POST同時(shí)支持圖片url和base64數(shù)據(jù)提交，get僅支持圖片url提交。文章來源地址http://www.zghlxwxcb.cn/news/detail-552422.html

代碼案例

   /**
     * 圖片轉(zhuǎn)Base64
     */
    public static String getImageBase() throws Exception {
        byte[] data = null;
        // 讀取圖片字節(jié)數(shù)組
        try {
            InputStream in = new FileInputStream("本地文件路徑");
            data = new byte[in.available()];
            in.read(data);
            in.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        // 對(duì)字節(jié)數(shù)組Base64編碼
        BASE64Encoder encoder = new BASE64Encoder();
        return encoder.encode(data);// 返回Base64編碼過的字節(jié)數(shù)組字符串
    }

    /**
     * 向指定 URL 發(fā)送POST方法的請(qǐng)求
     */
    public static String sendPost() throws Exception {
        Map<String, String> paramMap = new HashMap<String, String>();
        paramMap.put("key", "用戶請(qǐng)求秘鑰");
        paramMap.put("data", getImageBase());
        URL url = new URL("https://api.itapi.cn/api/ocr/v2");
        StringBuilder postData = new StringBuilder();
        //接口不支持json傳參，處理參數(shù)
        for (Map.Entry<String,String> param : paramMap.entrySet()) {
            if (postData.length() != 0) postData.append('&');
            postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
            postData.append('=');
            postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
        }
        byte[] postDataBytes = postData.toString().getBytes("UTF-8");

        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
        conn.setDoOutput(true);
        conn.getOutputStream().write(postDataBytes);

        Reader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));

        StringBuilder sb = new StringBuilder();
        for (int c; (c = in.read()) >= 0;)
            sb.append((char)c);
        String response = sb.toString();
        return response;
    }
