1.1 新建HttpUtils，用来发送post请求

1.2 获取 access token

1.3 获取图片的文字信息

1.4 测试

	public static void main(String[] args) {
    
    
        String ocrMessage = getOcrMessage();
        System.out.println(ocrMessage);
    }

1.5 结果

2.1 获取 access token

        Connection con = Jsoup.connect("https://aip.baidubce.com/oauth/2.0/token");

        JSONObject jsonObject = JSONObject.parseObject(body);
        String accessToken = jsonObject.get("access_token").toString();
        return accessToken;
    }

2.2 获取图片的文字信息

public static String getOcrMessage(String imgStr) throws IOException {
    
    
        String url = "https://aip.baidubce.com/rest/2.0/ocr/v1/accurate_basic" + "?access_token=" + getAccessToken();

        Connection.Response execute = con.ignoreContentType(true).method(Connection.Method.POST).execute();
        String body = execute.body();
        //利用阿里的fastjson解析
        JSONObject jsonObject = JSONObject.parseObject(body);
        String wordsResult = jsonObject.get("words_result").toString();
        //words_result是一个集合
        JSONArray jsonArray = JSONArray.parseArray(wordsResult);
        //组装解析后的结果
        StringBuilder sb = new StringBuilder();
        for (Object o : jsonArray) {
    
    
            //Object强转成JSONObject
            JSONObject jObject = (JSONObject) o;
            //解析words
            String words = jObject.get("words").toString();
            //组装到sb
            sb.append(words);
        }
        //返回结果
        return sb.toString();
    }

2.3 测试
