c# http协议 web api发送,获取方法-获取网页数据
public static HttpWebResponse CreatePostHttpResponse(string url, string json, ref string erro) { Console.WriteLine(url); HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;//创建请求对象 request.Method = "POST";//请求方式 request.ContentType = "application/json";//链接类型 try { if (!(json == null)) { Console.WriteLine(json); byte[] data = Encoding.UTF8.GetBytes(json); //写入请求流 using (Stream stream = request.GetRequestStream()) { stream.Write(data, 0, data.Length); } } erro = "订单请已发送...."; return request.GetResponse() as HttpWebResponse; } catch (Exception ex) { erro = ex.ToString(); erro = "error"; return null; } //构造查询字符串 }
获取:
public static string HttpGetString_orderSequence(string AGV_Name, ref string orderSequence, ref string OrderFinishTime) { // Url = "http://172.17.50.40:7120/api/route/vehicles/AMB-01" + Url; string query_URL; query_URL = "http://172.17.50.40:7120/api/route/vehicles/" + AGV_Name; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(query_URL); request.Method = "GET"; request.ContentType = "text/html;charset=UTF-8"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream myResponseStream = response.GetResponseStream(); StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8")); string retString = myStreamReader.ReadToEnd(); myStreamReader.Close(); myResponseStream.Close(); dynamic jsonStr = JsonConvert.DeserializeObject<dynamic>(retString); // jsonObj["destinations"][0]["locationName"] = $"{where_name}"; orderSequence = jsonStr["orderSequence"]; if (jsonStr["state"] == "FINISHED") retString = "true"; else retString = "false"; return retString; }
欢迎讨论,相互学习。
