作者：俏巴

概述

阿里云自然语言处理（Natural Language Processing）是为各类企业及开发者提供的用于文本分析及挖掘的核心工具，旨在帮助用户高效的处理文本，已经广泛应用在电商、文化娱乐、金融、物流等行业客户的多项业务中，取得了良好的效果。这里主要针对目前官方文档中参考Demo使用SDK较老且本身中文打印输出异常的问题，提供包括SDK安装步骤+正常可用示例.NET Demo。

操作步骤

1、Nuget 安装

aliyun-net-sdk-core

Install-Package aliyun-net-sdk-core -Version 1.5.3           

2、测试Demo

using Aliyun.Acs.Core;
using Aliyun.Acs.Core.Http;
using Aliyun.Acs.Core.Profile;
using System;           

namespace NLPDemo {

<span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">Program</span>
</span>{
    <span class="hljs-keyword">static</span> <span class="hljs-keyword">void</span> Main(string[] args)
    {
        <span class="hljs-comment">// ak,sk 获取参考链接：https://yq.aliyun.com/articles/693979</span>
        string accessKeyId = <span class="hljs-string">"******"</span>;
        string accessKeySecret = <span class="hljs-string">"******"</span>;
        IClientProfile profile = DefaultProfile.GetProfile(<span class="hljs-string">"cn-shanghai"</span>, accessKeyId, accessKeySecret);
        IAcsClient client = <span class="hljs-keyword">new</span> DefaultAcsClient(profile);
        string postBody = <span class="hljs-string">"{\"text\": \"China真丝韩都衣舍连衣裙\"}"</span>;
        CommonRequest request = <span class="hljs-keyword">new</span> CommonRequest();
        request.Domain = <span class="hljs-string">"nlp.cn-shanghai.aliyuncs.com"</span>;
        request.UriPattern = <span class="hljs-string">"/nlp/api/wordpos/general"</span>;
        request.Method = MethodType.POST;

        request.SetContent(System.Text.Encoding.UTF8.GetBytes(postBody), <span class="hljs-string">"utf-8"</span>, FormatType.JSON);
        request.AddHeadParameters(<span class="hljs-string">"x-acs-signature-method"</span>, <span class="hljs-string">"HMAC-SHA1"</span>);
        request.AddHeadParameters(<span class="hljs-string">"x-acs-signature-nonce"</span>, System.Guid.NewGuid().ToString());
        request.Action = <span class="hljs-string">"None"</span>;
        request.Version = <span class="hljs-string">"2018-04-08"</span>;
        CommonResponse response = client.GetCommonResponse(request);
        Console.WriteLine(response.Data);
        Console.ReadKey();
    }
}                

}
