如何在 .core 中使用“ReadAsAsync”

如何解决如何在 .core 中使用“ReadAsAsync”

我需要使用 cutt.ly URL 更短的 API，我遵循了它的文档以及我如何使用它

Cutt.ly documentation

class Program
{
    private const string URL = "https://cutt.ly/api/api.PHP";
    private static string urlParameters = "?key=ddbbdd323230fbf3e0b9&short=https://www.google.com&name=Test";
    static void Main(string[] args)
    {
        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri(URL);

        client.DefaultRequestHeaders.Accept.Add(
        new MediaTypeWithQualityHeaderValue("application/json"));

        HttpResponseMessage response = client.GetAsync(urlParameters).Result;.
        if (response.IsSuccessstatusCode)
        {
            var dataObjects = response.Content.ReadAsAsync().Result;
            foreach (var d in dataObjects)
            {
                Console.WriteLine("{0}",d.ToString());
            }
        }
        else
        {
            Console.WriteLine("{0} ({1})",(int)response.StatusCode,response.ReasonPhrase);
        }

        client.dispose();
        Console.ReadLine();
    }
}

但问题是我遇到了以下编译错误。

'HttpContent' does not contain a deFinition for 'ReadAsAsync' and no accessible extension method 'ReadAsAsync' accepting a first argument of type 'HttpContent' Could be found

我正在使用 .net 核心。我如何使用 .net core 处理这个问题。我找到了这个 question。但我不清楚它的答案。

解决方法

我在 here 之前这样做过 您必须安装 Newtonsoft.Json nuget 包

CuttlyApiKey 是您的 api 密钥，SelectedCustomText 是您的链接的自定义名称，如果您不想设置自定义名称，可以设置 string.empty

public async Task<string> CuttlyShorten(string longUrl)
        {

            try
            {
                string url = string.Format("https://cutt.ly/api/api.php?key={0}&short={1}&name={2}",CuttlyApiKey,HttpUtility.UrlEncode(longUrl),SelectedCustomText);

                using (HttpClient client = new HttpClient())
                using (HttpResponseMessage response = await client.GetAsync(url))
                using (HttpContent content = response.Content)
                {
                    dynamic root = JsonConvert.DeserializeObject<dynamic>(response.Content.ReadAsStringAsync().Result);

                    string statusCode = root.url.status;
                    if (statusCode.Equals("7"))
                    {
                        string link = root.url.shortLink;

                        return link;
                    }
                    else
                    {
                        string error = root.status;
                        
                    }

                }
            }
            catch (Exception ex)
            {
                
            }


            return "error";
        }

用法：

var shortUrl = await CuttlyShorten(url);

,

创建类并尝试以下代码：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script 
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>


<div class="col-lg-12 col-sm-6 companyBtn" id="3543">
  <div class="strip">
    <div class="row">
      <div class="col-2">
        <img class="img-fluid rounded-circle d-inline pr-2" style="max-width: 50px" src="https://i.picsum.photos/id/400/100/100.jpg?hmac=pvDsAYmMO0rcZJDGuhmCPDrPeCkJIkGR90-rqPYCMmw">
      </div>
      <div class="col-10">
        <div class="strip_info seenIcon">
          <div class="item_title">
            <h3 class="testTitle" style="width:90%;font-size:1.1rem">Test Company</h3>
            <small class="d-block mb-3">  <span class="flag-icon flag-icon-gb"></span>  United Kingdom</small>
            <small class="badge badge-warning">Artist Managers</small>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

您必须安装 Newtonsoft.Json nuget 包才能从 json 转换。
