.net平台借助第三方推送服务在推送Android消息(极光推送)
1,首先需要将你的app在极光官网上进行注册,获取一个ApiKey,一个APIMasterSecret(密码),将这两个值保存在配置文件(app/web.config)中,具体手机开发端需要做什么操作我们.net平台不管
<appSettings>
<add key="ApiKey" value="**********"/>
<add key="APIMasterSecret" value="*******"/>
</appSettings>
2,读取配置中的值
private readonly string ApiKey = "";
private readonly string APIMasterSecret = "";
ApiKey = ConfigurationManager.AppSettings["ApiKey"].ToString();//Android ApiKey
APIMasterSecret = ConfigurationManager.AppSettings["APIMasterSecret"].ToString();//Android密码
3,开始推送方法
复制代码
/// <summary>
/// Android极光推送
/// </summary>
/// <param name="RegistrationID">设备号</param>
public void PushAndroid(string RegistrationID)
{
try
{
Random ran = new Random();
int sendno = ran.Next(1, 2100000000);//随机生成的一个编号
string app_key = ApiKey;
string masterSecret = APIMasterSecret;
int receiver_type = 5;//接收者类型。2、指定的 tag。3、指定的 alias。4、广播:对 app_key 下的所有用户推送消息。5、根据 RegistrationID 进行推送。当前只是 Android SDK r1.6.0 版本支持
string receiver_value = RegistrationID;
int msg_type = 1;//1、通知2、自定义消息(只有 Android 支持)
string msg_content = "{\"n_builder_id\":\"00\",\"n_title\":\"" + Title + "\",\"n_content\":\"" + Content + "\"}";//消息内容
string platform = "android";//目标用户终端手机的平台类型,如: android, ios 多个请使用逗号分隔。
string verification_code = GetMD5Str(sendno.ToString(), receiver_type.ToString(), receiver_value,masterSecret);//验证串,用于校验发送的合法性。MD5
string postData = "sendno=" + sendno;
postData += ("&app_key=" + app_key);
postData += ("&masterSecret=" + masterSecret);
postData += ("&receiver_type=" + receiver_type);
postData += ("&receiver_value=" + receiver_value);
postData += ("&msg_type=" + msg_type);
postData += ("&msg_content=" + msg_content);
postData += ("&platform=" + platform);
postData += ("&verification_code=" + verification_code);
//byte[] data = encoding.GetBytes(postData);
byte[] data = Encoding.UTF8.GetBytes(postData);
string resCode = GetPostRequest(data);//调用极光的接口获取返回值
JpushMsg msg = Newtonsoft.Json.JsonConvert.DeserializeObject<JpushMsg>(resCode);//定义一个JpushMsg类,包含返回值信息,将返回的json格式字符串转成JpushMsg对象
}
catch (Exception ex)
{
}
}
复制代码
4,MD5加密验证字符串,用于调用接口的时候,极光将做验证使用
复制代码
/// <summary>
/// MD5字符串
/// </summary>
/// <param name="paras">参数数组</param>
/// <returns>MD5字符串</returns>
public string GetMD5Str(params string [] paras)
{
string str = "";
for(int i=0;i<paras.Length;i++)
{
str += paras[i];
}
byte[] buffer = MD5.Create().ComputeHash(Encoding.UTF8.GetBytes(str));
string md5Str = string.Empty;
for (int i = 0; i < buffer.Length; i++)
{
md5Str = md5Str + buffer[i].ToString("X2");
}
return md5Str;
}
复制代码
5,http Post方式调用极光的推送服务
复制代码
/// <summary>
/// Post方式请求获取返回值
/// </summary>
/// <param name="data"></param>
/// <returns></returns>
public string GetPostRequest(byte[] data)
{
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://api.jpush.cn:8800/v2/push");
myRequest.Method = "POST";//极光http请求方式为post
myRequest.ContentType = "application/x-www-form-urlencoded";//按照极光的要求
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Close();
// Get response
var response = (HttpWebResponse)myRequest.GetResponse();
using (var reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("UTF-8")))
{
string result = reader.ReadToEnd();
reader.Close();
response.Close();
return result;
}
}
复制代码
6,定义一个类,接收返回值
复制代码
public class JpushMsg
{
private string sendno;//编号
public string Sendno
{
get { return sendno; }
set { sendno = value; }
}
private string msg_id;//信息编号
public string Msg_id
{
get { return msg_id; }
set { msg_id = value; }
}
private string errcode;//返回码
public string Errcode
{
get { return errcode; }
set { errcode = value; }
}
private string errmsg;//错误信息
public string Errmsg
{
get { return errmsg; }
set { errmsg = value; }
}
}
