使用文本摘要API解析JSON响应，响应中存在编码错误

Question

我在https://www.meaningcloud.com/products/automatic-summarization使用服务进行文本摘要。我使用的是.NET Core5

例如，我想缩短这条新闻：https://e.vnexpress.net/news/business/economy/vn-index-rises-for-third-straight-session-4141865.html

string input = "..." // long content of news post.
var client = new RestClient("https://api.meaningcloud.com/summarization-1.0");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddParameter("key", "25870359b682ec3c93f9becd850eb459");  // fake token because this content is public.        
request.AddParameter("sentences", 4);
request.AddParameter("txt", JsonEncodedText.Encode(content));

IRestResponse response = client.Execute(request);
System.Threading.Thread.Sleep(3000);
var res = JObject.Parse(response.Content);
// Need convert \r\n , \r\n\r\n to space.
string short_content = res["summary"].ToString();
// SysUtil.StringEncodingConvert(short_content, "ISO-8859-1", "UTF-8");            
string result = raw_string.Replace(" [...] ", " ");

The benchmark VN-Index saw steady growth throughout the day, gradually gaining a total of 10.23 points by the end of the session.

我也尝试使用util

using System;

namespace myproj.Controllers
{

    public class SysUtil
    {
        public static String StringEncodingConvert(String strText, String strSrcEncoding, String strDestEncoding)
        {
            System.Text.Encoding srcEnc = System.Text.Encoding.GetEncoding(strSrcEncoding);
            System.Text.Encoding destEnc = System.Text.Encoding.GetEncoding(strDestEncoding);
            byte[] bData = srcEnc.GetBytes(strText);
            byte[] bResult = System.Text.Encoding.Convert(srcEnc, destEnc, bData);
            return destEnc.GetString(bResult);
        }
    }

}

但不是成功。

就算我换了，还是不成功

tring result2 = result.Replace("\u2019s", "'s");

我发现了一些问题

\u2019s -->我需要's，怎么归档？

Answer 1

\u2019是智能报价的unicode字符。只需替换它：

result2 = result.Replace('\u2019', '\'')
