1.Post 请求发送方式
实例：
const string sResponseEncoding = "gb2312";
//测试文本信息
string postText = "{\"touser\":\"OpenId\",\"msgtype\":\"text\",\"text\":{\"content\":\"Hello World\"}}";
//测试图文信息
string postNews = "{\"touser\":\"OpenId\",\"msgtype\":\"news\",\"news\":{\"articles\":[{\"title\":\"测试1\",\"description\":\"Is Really A Happy Day\",\"url\":\"URL\",\"picurl\":\"http://avatar.csdn.net/C/2/8/1_zhoufoxcn.jpg\"},{\"title\":\"测试2\",\"description\":\"Is Really A Happy Day\",\"url\":\"URL\",\"picurl\":\"http://avatar.csdn.net/C/2/8/1_zhoufoxcn.jpg\"}]}}";
const string url = "http；//URL";
HttpWebRequest webrequest = (HttpWebRequest)HttpWebRequest.Create(url);
webrequest.Method = "post";
webrequest.Timeout = 10000; //响应时间时间
webrequest= "application/json;charset=UTF-8"; //传递格式
webrequest.Credentials = CredentialCache.DefaultCredentials; //请求的身份验证信息为默认
string key = "My-Key"; //默认密钥
string timestamp = DateTime.Now.Ticks.ToString();//时间戳
webrequest.Headers.Add(“key”, key);
webrequest.Headers.Add(“timestamp”, timestamp);
//字符-字节-流
byte[] postdatabyte = Encoding.UTF8.GetBytes(postText);
webrequest.ContentLength = postdatabyte.Length;
Stream stream;
stream = webrequest.GetRequestStream();
stream.Write(postdatabyte, 0, postdatabyte.Length);
stream.Close();
Stream responseStream;
try
{ responseStream = webrequest.GetResponse().GetResponseStream(); }
catch (Exception e)
{ Console.WriteLine(string.Format("POST 操作发生异常：{0}", e.Message)); throw e; }
string stringResponse = string.Empty;
using (StreamReader responseReader = new StreamReader(responseStream, Encoding.GetEncoding(sResponseEncoding)))
{
stringResponse = responseReader.ReadToEnd();
}
responseStream.Close();
Console.WriteLine(stringResponse);
Console.ReadKey();
2.Get 请求方式（httpClient）
HttpClient httpClient = new HttpClient();
string key = "My-Key"; //默认密钥
string timestamp = DateTime.Now.Ticks.ToString();
string url = “”；
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, url);
request.Headers.Add(key, key);
request.Headers.Add(timestamp, timestamp);
HttpResponseMessage responseMessage = await httpClient.SendAsync(request);
Console.WriteLine(await responseMessage.Content.ReadAsStringAsync());
Console.ReadKey();
3.服务器接口
public ActionResult ReceiveData(string jsonpcallback)
{
var headers = HttpContext.Request.Headers.ToString();//获取headers 内容
Stream s = System.Web.HttpContext.Current.Request.InputStream;
byte[] receByte = new byte[s.Length];
s.Read(receByte, 0, (int)s.Length);
var receData = Encoding.UTF8.GetString(receByte);
var JsReceData = Newtonsoft.Json.JsonConvert.DeserializeObject<WxReceive>(receData);
//返回参数格式
if (string.IsNullOrEmpty(jsonpcallback))
return Json(QRTxt);
else
return JavaScript(string.Format("{0}({1});", jsonpcallback, Newtonsoft.Json.JsonConvert.SerializeObject(QRTxt)));
}
//声明实体类
public class WxReceive
{
public string touser { get; set; }
public string msgtype { get; set; }
}
//微信图文消息实体类
public class WxReceiveNews
{
public string touser { get; set; }
public string msgtype { get; set; }
public news news { get; set; }
}
public class news
{
public List<articles> articles { get; set; }
}
public class articles
{
public string title { get; set; }
public string description { get; set; }
public string url { get; set; }
public string picurl { get; set; }
}
4.其它
传递到服务器Base64，字符串进行URL解码：
HttpUtility.UrlDecode(data.ToString().Trim());
