httppost请求.
applicationkey/x-www-form-urlencoded请求: Email=321a&Name=kkfew
webapi里面, 如果用实体, 能接受到. 因为这是一个属性一个属性去匹配的原因
application/json
请求:{Email:321a , Name:kkfew}
如果接收参数为dynamic, 则没有问题.
因为直接把json对象转化成dynamic对象了
using (WebClient webclient = new WebClient()) { string apiurl = "http://192.168.1.225:9090/api/v3productsapi/GetStatisticInfo"; webclient.Encoding = UTF8Encoding.UTF8; string auth_key = string.Format("{0}:{1}:{2}", ts.TotalSeconds, randomStr, token); webclient.Headers.Add("Custom-Auth-Key", auth_key); Console.Write(webclient.DownloadString(apiurl)); } using (var client = new HttpClient()) { client.BaseAddress = new Uri("http://192.168.1.225:9090/"); client.DefaultRequestHeaders.Add("aa", "11"); var result = client.GetStringAsync("/api/v3productsapi/GetStatisticInfo").Result; Console.WriteLine(result); }
