普通Get数据和Post数据
1 public static string Get(string URL) 2 { 3 String ReCode = string.Empty; 4 try 5 { 6 HttpWebRequest wNetr = (HttpWebRequest)HttpWebRequest.Create(URL); 7 HttpWebResponse wNetp = (HttpWebResponse)wNetr.GetResponse(); 8 wNetr.ContentType = "text/html"; 9 wNetr.Method = "Get";10 Stream Streams = wNetp.GetResponseStream();11 StreamReader Reads = new StreamReader(Streams, Encoding.UTF8);12 ReCode = Reads.ReadToEnd();13 14 //封闭临时不实用的资料 15 Reads.Dispose();16 Streams.Dispose();17 wNetp.Close();18 }19 catch (Exception ex) { throw ex; }20 21 return ReCode;22 23 }24 25 public static string Post(string url, string data)26 {27 string returnData = null;28 try29 {30 //byte[] buffer = Encoding.UTF8.GetBytes(data);31 //HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(url);32 //webReq.Method = "POST";33 //webReq.ContentType = "application/x-www-form-urlencoded";34 //webReq.ContentLength = buffer.Length;35 //Stream postData = webReq.GetRequestStream();36 //webReq.Timeout = 99999999;37 ////webReq.ReadWriteTimeout = 99999999;38 //postData.Write(buffer, 0, buffer.Length);39 //postData.Close();40 //HttpWebResponse webResp = (HttpWebResponse)webReq.GetResponse();41 //Stream answer = webResp.GetResponseStream();42 //StreamReader answerData = new StreamReader(answer);43 //returnData = answerData.ReadToEnd();44 45 string strURL = url;46 System.Net.HttpWebRequest request;47 request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);48 request.Method = "POST";49 request.ContentType = "application/json;charset=UTF-8";50 string paraUrlCoded = data;51 byte[] payload;52 payload = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);53 request.ContentLength = payload.Length;54 Stream writer = request.GetRequestStream();55 writer.Write(payload, 0, payload.Length);56 writer.Close();57 System.Net.HttpWebResponse response;58 response = (System.Net.HttpWebResponse)request.GetResponse();59 System.IO.Stream s;60 s = response.GetResponseStream();61 string StrDate = "";62 string strValue = "";63 StreamReader Reader = new StreamReader(s, Encoding.UTF8);64 while ((StrDate = Reader.ReadLine()) != null)65 {66 strValue += StrDate + "\r\n";67 }68 returnData = strValue;69 }70 catch71 {72 return "获取错误";73 }74 return returnData.Trim() + "\n";75 }76 /// 77 /// 将json数据反序列化为Dictionary78 /// 79 /// json数据80 /// JsonToDictionary(string jsonData)82 {83 //实例化JavaScriptSerializer类的新实例。。。需要添加 System.Web.Extensions引用84 JavaScriptSerializer jss = new JavaScriptSerializer();85 try86 {87 //将指定的 JSON 字符串转换为 Dictionary 类型的对象88 return jss.Deserialize >(jsonData);89 }90 catch (Exception ex)91 {92 throw new Exception(ex.Message);93 }94 } 附.另外一个Post
public void Post(){ var d = new SendNews(); d.touser = touser; d.agentid = "7"; d.Description = wxmsg; HttpClient client = new HttpClient(); client.BaseAddress = new Uri("http://localhost:47870/"); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); HttpResponseMessage response = client.PostAsJsonAsync("api/SendMsg/SendNews", d).Result; } public class SendNews { /// /// UserID列表（消息接收者，多个接收者用‘|’分隔）。特殊情况：指定为@all，则向关注该企业应用的全部成员发送 /// public string touser { get; set; } /// /// PartyID列表，多个接受者用‘|’分隔。当touser为@all时忽略本参数 /// public string toparty { get; set; } /// /// TagID列表，多个接受者用‘|’分隔。当touser为@all时忽略本参数 /// public string totag { get; set; } /// /// 消息类型 /// public string msgtype { get; set; } /// /// 企业应用的id，整型。可在应用的设置页面查看 /// public string agentid { get; set; } /// /// 表示是否是保密消息，0表示否，1表示是，默认0 /// public string safe { get; set; } /// /// 文章标题 /// public string Title { get; set; } /// /// 文章描述 /// public string Description { get; set; } /// /// 图片链接，支持JPG、PNG格式，较好的效果为大图360*200，小图200*200 /// public string PicUrl { get; set; } /// /// 点击图文消息跳转链接 /// public string Url { get; set; } }
键值对提交
//重点！！ 成功 利用Webclient Post 按字段的方式提交每个字段的内容给服务器端 public string WebClientPost(string url, System.Collections.Specialized.NameValueCollection PostVars) { try { System.Net.WebClient WebClientObj = new System.Net.WebClient(); byte[] byRemoteInfo = WebClientObj.UploadValues(url, "POST", PostVars); //下面都没用啦，就上面一句话就可以了 string sRemoteInfo = System.Text.Encoding.Default.GetString(byRemoteInfo); return sRemoteInfo; } catch { return ""; } } public void test() { System.Collections.Specialized.NameValueCollection PostVars = new System.Collections.Specialized.NameValueCollection(); PostVars.Add("test", "value"); PostVars.Add("cmd", "value"); PostVars.Add("token", "value"); WebClientPost("url", PostVars); }
