信鸽官方sdk没提供C#版的DEMO，考虑到应该有其他.NET的也会用到信鸽，下面是我在使用信鸽过程中写的demo。有什么不对的地方，欢迎各位大牛指导。
使用过程中主要是有2个问题:
1.参数组装,本demo使用Dictionary进行组装和排序;
2.生成 sign(签名)
下文贴出单个设备推送的代码(忽略大多数辅组实体的代码,下面会贴上源代码)
1.Android 消息实体类 Message
public class Message
{
public Message()
{
this.title = "";
this.content = "";
this.sendTime = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
this.accept_time = new List<TimeInterval>();
this.multiPkg = ;
this.raw = "";
this.loopInterval = -;
this.loopTimes = -;
this.action = new ClickAction();
this.style = new Style();
this.type = Message.TYPE_MESSAGE;
}
public bool isValid()
{
if (!string.IsNullOrWhiteSpace(raw))
{
return true;
}
if (type < TYPE_NOTIFICATION || type > TYPE_MESSAGE)
return false;
if (multiPkg < || multiPkg > )
return false;
if (type == TYPE_NOTIFICATION)
{
if (!style.isValid()) return false;
if (!action.isValid()) return false;
}
if (expireTime < || expireTime > * * * )
return false;
try
{
DateTime.Parse(sendTime);
}
catch (Exception e)
{
return false;
}
foreach (var item in accept_time)
{
if (!item.isValid()) return false;
}
if (loopInterval > && loopTimes >
&& ((loopTimes - ) * loopInterval + ) > )
{
return false;
} return true;
}
public string ToJosnByType()
{
if (type == TYPE_MESSAGE)
{
var obj = new { title = title, content = content, accept_time = accept_time.ToJson() };
return obj.ToJson();
}
return this.ToJson();
}
/// <summary>
/// 1：通知
/// </summary>
public static readonly int TYPE_NOTIFICATION = ;
/// <summary>
/// 2：透传消息
/// </summary>
public static readonly int TYPE_MESSAGE = ;
public String title;
public String content;
public int expireTime;
public String sendTime;
private List<TimeInterval> accept_time;
public int type;
public int multiPkg;
private Style style;
private ClickAction action;
/// <summary>
/// 自定义参数，所有的系统app操作参数放这里
/// </summary>
public string custom_content;
public String raw;
public int loopInterval;
public int loopTimes;
}
2.组装参数函数
/// <summary>
/// Android单个设备 推送信息
/// </summary>
/// <param name="deviceToken">针对某一设备推送，token是设备的唯一识别 ID</param>
/// <param name="message"></param>
/// <returns></returns>
public string pushSingleDevice(String deviceToken, Message message)
{
if (!ValidateMessageType(message))
{
return "";
}
if (!message.isValid())
{
return "";
}
Dictionary<String, Object> dic = new Dictionary<String, Object>();
dic.Add("access_id", this.m_accessId);
dic.Add("expire_time", message.expireTime);
dic.Add("send_time", message.sendTime);
dic.Add("multi_pkg", message.multiPkg);
dic.Add("device_token", deviceToken);
dic.Add("message_type", message.type);
dic.Add("message", message.ToJson());
dic.Add("timestamp", DateTime.Now.DateTimeToUTCTicks()); return CallRestful(XinGeAPIUrl.RESTAPI_PUSHSINGLEDEVICE, dic);
}
3.生成签名
/// <summary>
/// 生成 sign（签名）
/// </summary>
/// <param name="method"></param>
/// <param name="url"></param>
/// <param name="dic"></param>
/// <returns></returns>
protected String GenerateSign(String method, String url, Dictionary<String, Object> dic)
{
var str = method;
Uri address = new Uri(url);
str += address.Host;
str += address.AbsolutePath;
var dic2 = dic.OrderBy(d => d.Key);
foreach (var item in dic2)
{
str += (item.Key + "=" + (item.Value == null ? "" : item.Value.ToString()));
}
str += this.m_secretKey;
var s_byte = Encoding.UTF8.GetBytes(str);
MD5 md5Hasher = MD5.Create();
byte[] data = md5Hasher.ComputeHash(s_byte);
StringBuilder sBuilder = new StringBuilder();
for (int i = ; i < data.Length; i++)
{
sBuilder.Append(data[i].ToString("x2"));
}
return sBuilder.ToString();
}
4.生成请求的地址和调用请求
/// <summary>
/// 生成请求的地址和调用请求
/// </summary>
/// <param name="url"></param>
/// <param name="dic"></param>
/// <returns></returns>
protected string CallRestful(String url, Dictionary<String, Object> dic)
{
String sign = GenerateSign("POST", url, dic);
if (string.IsNullOrWhiteSpace(sign))
{
return (new { ret_code = -, err_msg = "generateSign error" }).ToJson();
}
dic.Add("sign", sign);
try
{
var param = "";
foreach (var item in dic)
{
var key = item.Key;
var value = HttpUtility.UrlEncode(item.Value == null ? "" : item.Value.ToString(), Encoding.UTF8);
param = string.IsNullOrWhiteSpace(param) ? string.Format("{0}={1}", key, value) : string.Format("{0}&{1}={2}", param, key, value);
}
return Request(url, "POST", param); }
catch (Exception e)
{ return e.Message;
}
}
5.辅助校验方法
protected bool ValidateMessageType(Message message)
{
if (this.m_accessId < XinGeAPIUrl.IOS_MIN_ID)
return true;
else
return false;
}
6.Http请求
public string Request(string _address, string method = "GET", string jsonData = null, int timeOut = )
{
string resultJson = string.Empty;
if (string.IsNullOrEmpty(_address))
return resultJson;
try
{
Uri address = new Uri(_address); // 创建网络请求
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
//System.Net.ServicePointManager.DefaultConnectionLimit = 50;
// 构建Head
request.Method = method;
request.KeepAlive = false;
Encoding myEncoding = Encoding.GetEncoding("utf-8");
if (!string.IsNullOrWhiteSpace(jsonData))
{
byte[] bytes = Encoding.UTF8.GetBytes(jsonData);
using (Stream reqStream = request.GetRequestStream())
{
reqStream.Write(bytes, , bytes.Length);
reqStream.Close();
}
}
request.Timeout = timeOut * ;
request.ContentType = "application/x-www-form-urlencoded";
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string responseStr = reader.ReadToEnd();
if (responseStr != null && responseStr.Length > )
{
resultJson = responseStr;
}
}
}
catch (Exception ex)
{
resultJson = ex.Message;
}
return resultJson;
}
7.发送一个推送
public bool pushSingleDevice(String deviceToken, string account, string title, string content, Dictionary<string, object> custom, out string returnStr)
{
content = content.Replace("\r", "").Replace("\n", ""); Message android = new Message();
android.title = title;
android.content = content;
android.custom_content = custom.ToJson();
returnStr = pushSingleDevice(deviceToken, android);
return true;
}
注意：IOS需要区分开发和正式环境
