C#百度图片识别API调用返回数据包解析

百度图片识别api接口

  public static JObject GeneralBasic(string apikey,string secretkey,string path)
        {
            var client = new Baidu.Aip.Ocr.Ocr(apikey, secretkey);
            var image = File.ReadAllBytes(path);

            // 通用文字识别
            var result = client.GeneralBasic(image, null);
            return result;
        }

调用,方法,以及返回json 解析

     private void txbupload_Click(object sender, EventArgs e)
        {
            string apikey = txbapikey.Text;
            string secretkey = txbsercetkey.Text;
            string imagepath = txbpic.Text+ "\\yancaoxuke.jpg";
            JObject result =   OcrDemo.GeneralBasic(apikey, secretkey, imagepath);          
                var txts = (from obj in (JArray)result.Root["words_result"]
                         //   let phrase = (JObject)obj["phrase"]
                            select (string)obj["words"]);
            foreach (var r in txts)
                Console.WriteLine(r);
       
        }

参考:1

const string s = "{\"result\" : \"ok\",\"tuc\" : [ {\"authors\" : [ 13 ],\"meaningId\" : 2397164096556578585,\"phrase\" : {\"text\" : \"机场\",\"language\" : \"zho\" }},{\"authors\" : [ 3266 ],\"meaningId\" : 1269040436618011315,\"phrase\" : {\"text\" : \"機場\",\"language\" : \"zho\"}}]}";
var root = JObject.Parse(s);
var txts = (from obj in (JArray)root["tuc"]
            let phrase = (JObject)obj["phrase"]
            select (string)phrase["text"]);
foreach (var r in txts)
    Console.WriteLine(r);

2:

const string s = "{\"result\" : \"ok\",\"tuc\" : [ {\"authors\" : [ 13 ],\"meaningId\" : 2397164096556578585,\"phrase\" : {\"text\" : \"机场\",\"language\" : \"zho\" }},{\"authors\" : [ 3266 ],\"meaningId\" : 1269040436618011315,\"phrase\" : {\"text\" : \"機場\",\"language\" : \"zho\"}}]}";
var root = JObject.Parse(s);
var txts = (from obj in (JArray)root["tuc"]
            select (string)obj["phrase"]["text"]);
foreach (var r in txts)
    Console.WriteLine(r);
