C#使用HttpClient进行GET&POST

就放两个代码过来吧，稍微做个记录

这是通过HttpClient.GetAsync(uri)进行HTTP数据获取的方式，验证参数似乎需要添加在uri之后，所以这段代码在实际应用中需要进行部分更改，将uri及验证信息作为函数输入

        public async void HttpClientDoGet()        {            var uri = "http://api.wsncloud.com/device/v1/list?";            var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.None };            using (var httpclient = new HttpClient(handler))            {                httpclient.BaseAddress = new Uri(uri);                httpclient.DefaultRequestHeaders.Accept.Clear();                httpclient.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));                HttpResponseMessage response = await httpclient.GetAsync("?ak=xxxxxxxxxxxxxxxxxxxx");                                if(response.IsSuccessStatusCode)                {                    Stream myResponseStream = await response.Content.ReadAsStreamAsync();                    StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));                    string retString = myStreamReader.ReadToEnd();                    myStreamReader.Close();                    myResponseStream.Close();                    MessageBox.Show(retString);                }            }        }

这个则为通过HttpClient.PostAsync(ur1, content)获取HTTP数据的方法

        public async void HttpClientDoPost()        {            var uri = "http://api.wsncloud.com/sensor/v1/list?";            var handler = new HttpClientHandler() { AutomaticDecompression = DecompressionMethods.None };            using (var httpclient = new HttpClient(handler))            {                httpclient.BaseAddress = new Uri(uri);                var content = new FormUrlEncodedContent(new Dictionary<string, string>()                   {                       {"ak", "65fc7ca4fc441d26f71bf3d691b278c2"},                       {"deviceId", "537eb34be4b022b7fbe19471"}                   });                var response = await httpclient.PostAsync(uri, content);                string responseString = await response.Content.ReadAsStringAsync();                MessageBox.Show(responseString);            }        }

Post和Get命令在实际使用中都可以用来获取服务器端的参数
