下面针对LTP分词算法 实践

1.登录官网 获取授权码api_key

2.分词接口操作 

接口参数:

 StringBuilder sb = new StringBuilder();
            sb.Append(" 本报讯 (记者 王少勇)3月28日,国土资源部部长、党组书记、国家土地总督察姜大明主持召开第10次部党组会议,传达学习习xx总书记在北京市考察工作时的重要讲话精神。会议提出,要深刻理解习xx总书记重要讲话精神,充分发挥国土资源部门的服务和保障作用,推进京津冀协同发展。  xx平总书记高度重视北京发展和京津冀协同发展,今年2月下旬专程到北京市调研考察,并发表重要讲话,从做好北京发展和管理工作、推动京津冀协同发展两个方面进行了深刻阐述。会议指出,习xx总书记的重要讲话,对于实现京津冀优势互补、促进环渤海经济区发展、带动北方腹地发展,意义重大、影响深远,要认真学习,深刻领会。 会议提出,国土资源部门要进一步解放思想,加大改革创新力度,");            
            string url = "http://ltpapi.voicecloud.cn/analysis/";
            string data = "api_key=xxx&text=" + sb.ToString() + "&pattern=ws&format=xml";
            string returnValue= HttpHelper.HttpPost(url,data);
            Console.WriteLine(returnValue);
            Console.ReadKey();
 /// <summary>
        /// Post请求 webClient
        /// </summary>
        /// <param name="Url">地址</param>
        /// <param name="postString">这里即为传递的参数,可以用工具抓包分析,也可以自己分析,主要是form里面每一个name都要加进来  </param>
        /// <returns></returns>
        public static string HttpPost(string url, string postString)
        {
            byte[] postData = Encoding.UTF8.GetBytes(postString);//编码,尤其是汉字,事先要看下抓取网页的编码方式  
            WebClient webClient = new WebClient();
            webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");//采取POST方式必须加的header,如果改为GET方式的话就去掉这句话即可  
            byte[] responseData = webClient.UploadData(url, "POST", postData);//得到返回字符流  
            string srcString = Encoding.UTF8.GetString(responseData);//解码 
            return srcString;
        }

3.测试结果
