Question

使用以下命令：

curl -v -X GET -H "Content-Type: application/json" -d {'"mode":"0"'} http://host.domain.abc.com:23423/api/start-trial-api/

我能够将JSON数据发送到Web请求并获取响应。我怎样才能在C＃中做同样的事情？

我能够将数据发布到其他服务并获得响应，但不了解如何将数据发送到GET请求。我尝试在谷歌和stackoverflow上搜索相同的C＃，但没有找到任何东西。

Answer 1

示例代码 - 确保请求方法设置为＆＃34; GET＆＃34;

        string url = "";
        var request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "GET";
        request.ContentType = "application/json";

        var webResponse = request.GetResponse();

        using (var s = webResponse.GetResponseStream())
        {
            using (TextReader textReader = new StreamReader(s, true))
            {
               string jsonString = textReader.ReadToEnd();
            }
        }

此处有很多abstractions，但希望能在C#

中提供有关如何连接服务的粗略指南

public interface IShopifyAPIGateway
{
   HttpResponseMessage Get(string path);
}

Shopify API网关，instatiates HTTPClient()

public sealed class ShopifyAPIGateway : IShopifyAPIGateway
        {
            /// <summary>
            /// 
            /// </summary>
            private Identity _identity;
            /// <summary>
            /// 
            /// </summary>
            private HttpClient _httpClient;
            /// <summary>
            /// 
            /// </summary>
            public ShopifyAPIGateway(Identity
                identity)
            {
                _identity = identity;
                _httpClient = new HttpClient(ClientHandler());
            }
            /// <summary>
            /// 
            /// </summary>
            /// <returns></returns>
            public HttpResponseMessage Get(string path)
            {
                try
                {
                    var response =  Connect().GetAsync(path).Result;
                    return response;
                }
                catch (CustomHttpResponseException ex)
                {
                    new Email().SendEmail(_identity.ClientName, "Http Response Error - Shopify API Module",
                     "Http Response Error - Shopify API Module: " + ex.Message,
                     "error@retain.me");

                    throw new CustomHttpResponseException(ex.Message);
                }

            }
            /// <summary>
            /// 
            /// </summary>
            /// <returns></returns>
            private HttpClient Connect()
            {
                try
                {
                    _httpClient.BaseAddress = new Uri(_identity.APIURL);
                    return _httpClient;
                }
                catch (CustomHttpRequestException ex)
                {
                    throw new CustomHttpRequestException(ex.Message);
                }

            }
            /// <summary>
            /// 
            /// </summary>
            /// <param name="userKey"></param>
            /// <returns></returns>
            private HttpClientHandler ClientHandler()
            {
                try
                {
                    return new HttpClientHandler()
                    {
                        Credentials = new NetworkCredential(_identity.APIKey,
                                                            _identity.Password),
                        PreAuthenticate = true
                    };
                }
                catch (CustomClientHandlerException ex)
                {    
                    throw new CustomClientHandlerException(ex.Message);   
                }
            }
        }

通用存储库返回响应对象与object(s)匹配的任何T

public sealed class EntityRepository<T> : IEntityRepository<T>
    {
        private IShopifyAPIGateway _gateWay;
        public T Find(string path)
        {
            try
            {
                _gateWay = new ShopifyAPIGateway(_identity);
                var json = _gateWay.Get(path).Content.ReadAsStringAsync();
                T results = JsonConvert.DeserializeObject<T>(json.Result);

                return results;
            }
            catch (System.Exception ex)
            {
                throw new ApplicationException(ex.Message);
            }

        }

    }

使用返回类型必须与您传递的Type相匹配，并且还必须与响应中返回的类型相匹配。

private IEnumerable<Order> Orders()
{
   var entityRepo = new EntityRepository<Order>();
   return entityRepo.Find("somedomain/api/orders?mode=0", _identity);
}
