使用C#调用REST-Api

本文关键字：REST-Api 调用 使用 | 更新日期: 2023-09-27 18:01:09

我使用C#调用Rest API。URL在浏览器中工作，但当我从c#调用它时，一个异常被称为

A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.dll
A first chance exception of type 'System.Net.WebException' occurred in System.dll
A first chance exception of type 'System.Net.WebException' occurred in System.dll
A first chance exception of type 'System.Net.WebException' occurred in System.dll

这是我的代码

public static void getInputFromTeam1()
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://192.168.150.1:8090/api/storeLayout/kinectToRacks/42");
            request.Method = "GET";
            request.Accept = "application/json";

            try
            {
                WebResponse webResponse = request.GetResponse();
                using (Stream webStream = webResponse.GetResponseStream())
                {
                    if (webStream != null)
                    {
                        using (StreamReader responseReader = new StreamReader(webStream))
                        {
                            string response = responseReader.ReadToEnd();
                            Console.Out.WriteLine(response);
                        }
                    }
                }
            }
            catch (Exception e)
            {
                Console.Out.WriteLine("-----------------");
                Console.Out.WriteLine(e.Message);
            }
        }

我是C#和Rest Api的新手。请帮帮我，我读了很多答案，但没有一个有效。请帮我谢谢你。

使用C#调用REST-Api

我建议您改为查看高级WebClient-类。您仍然必须密切注意异常消息。

        var serviceRequest = new WebClient();
        string response = serviceRequest.DownloadString(new Uri(url));

您可以使用此代码。

            using (var client = new HttpClient())
            {
                client.BaseAddress = new Uri("http://192.168.150.1:8090/");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                HttpResponseMessage response = client.GetAsync("api/storeLayout/kinectToRacks/42").Result;
                if (response.IsSuccessStatusCode)
                {
                    var str = response.Content.ReadAsStringAsync();
                }
            }
