Get 和 Post 使用篇（1）

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());
