java实现即时通信的完整步骤分享

作者:氵何章怀晓 。

这篇文章主要给大家介绍了关于java实现即时通信的完整步骤,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

前言

移动社交是我们日常生活中很常见的软件,最近在做即时通信,我用的是环信,和大家分享一下~~
环信的API都是基于JSON的,所以在构造HTTP请求的时候,要指定请求头


注意==》环信API必须携带token才可以访问。

创建一个认证类

	public class Authentic {

 private static Token token = new Token();

 private TalkHttpService service;

 public Authentic(TalkHttpService service) {
 this.service = service;
 }

 public Authentic(TalkHttpService service, Token token) {
 this.service = service;
 if (token != null) {
  Authentic.token = token;
 }
 }

 public Token getToken() {
 this.flush();
 return token;
 }

 public void task() {
 this.flush();
 }

 /**
 * @describe 申请认证 POST PUT 这两种请求携带参数
 * @author 何章怀晓 hezhanghuaixiao
 * @date 2020/9/8 17:02
 * @other
 */
 public void applyAuthentication(HttpEntityEnclosingRequestBase request) {
 this.flush();
 request.addHeader("Authorization", "Bearer " + token.toString());
 }
 /**
 * @describe 申请认证 GET DELETE 这两种请求不携带参数
 * @author 何章怀晓 hezhanghuaixiao
 * @date 2020/9/8 17:02
 * @other
 */
 public void applyAuthentication(HttpRequestBase request) {
 this.flush();
 request.addHeader("Authorization", "Bearer " + token.toString());
 }

 private void flush() {
 synchronized (Authentic.class) {
  try {
  //如果超时
  if (token.isExpire()) {
   //判断APPID和秘钥信息
   if (_Global.APP_CLIENT_ID != null && _Global.APP_CLIENT_SECRET != null) {
   Map<String, Object> param = new HashMap<String, Object>();
   param.put("grant_type", "client_credentials");
   param.put("client_id", _Global.APP_CLIENT_ID);
   param.put("client_secret", _Global.APP_CLIENT_SECRET);
   //请求获取token
   TalkNode res = service
    .request(_Global.URR_TOKEN, _Global.HTTP_METHOD_POST, param, null, null);
   //成功获取token
   if (res != null && res.getAccess_token() != null && res.getExpires_in() != null
    && res.getExpires_in() > 0) {
    //赋值
    token = new Token(res.getAccess_token(),
     res.getExpires_in() * 1000 + System.currentTimeMillis());
   }
   }
  }
  } catch (Exception e) {
  e.printStackTrace();
  }
 }
 }

 public static class Token {

 private String token;
 private Long expire;

 public Token() {
 }

 public Token(String token, long expire) {
  this.token = token;
  this.expire = expire;
 }

 public String getToken() {
  return token;
 }

 public void setToken(String token) {
  this.token = token;
 }

 public Long getExpire() {
  return expire;
 }

 public void setExpire(Long expire) {
  this.expire = expire;
 }

 public boolean isExpire() {
  return expire == null || System.currentTimeMillis() > expire;
 }

 @Override
 public String toString() {
  return token;
 }
 }
}

创建请求接口

public interface TalkHttpService {
	/**
	 @describe
	 @param
		* @param url 请求地址

	 * @param method	请求方法

	 * @param param	参数

	 * @param auth	加密认证

	 * @param field	字段转换
	 @return com.hedashi.protal.model.TalkNode
	 @author 何章怀晓 hezhanghuaixiao
	 @date 2020/9/8 17:21
	 @other
	 */
	 TalkNode request(String url, int method, Object param,
  Authentic auth, String[][] field) throws Exception;

	/**
	 @describe
	 @param
		* @param url 请求地址

	 * @param file	文件名称

	 * @param auth	加密认证

	 * @param equal	字段转换
	 @return com.hedashi.protal.model.TalkNode
	 @author 何章怀晓 hezhanghuaixiao
	 @date 2020/9/8 17:21
	 @other
	 */
	 TalkNode upload(String url, File file, Authentic auth,
  String[][] equal) throws Exception;


	/**
	 @describe
	 @param
		* @param url 请求地址

	 * @param file	文件名称

	 * @param auth	加密认证

	 * @param header	请求头
	 @return void
	 @author 何章怀晓 hezhanghuaixiao
	 @date 2020/9/8 17:21
	 @other
	 */
	 void downLoad(String url, File file, Authentic auth,
  Map<String, String> header) throws Exception;

}

创建全局变量对不同模块操作

/*
 @describe 全局变量
 @params
 @return 
 @author 何章怀晓
 @date 2020/7/30 9:30
 @other
 */
public class _Global {
	
	public static String APP_KEY = "";
	public static String APP_CLIENT_ID = "";
	public static String APP_CLIENT_SECRET = "";
	//每页数量
	public static int APP_PAGE_SIZE = 10;
	public static final int HTTP_METHOD_GET = 1;
	public static final int HTTP_METHOD_POST = 2;
	public static final int HTTP_METHOD_PUT = 3;
	public static final int HTTP_METHOD_DELETE = 4;
	public static final String URL_HOST = "http://a1.easemob.com/"+APP_KEY.replace("#","/")+"/";
	public static final String URR_TOKEN = URL_HOST+"token";
	public static final String URL_CHAT = URL_HOST+"chatmessages";
	public static final String URL_GROUP = URL_HOST+"chatgroups";
	public static final String URL_FILE = URL_HOST+"chatfiles";
	public static final String URL_ROOM = URL_HOST+"chatrooms";
	public static final String URL_MESSAGES = URL_HOST+"messages";
	public static final String URL_USER = URL_HOST+"users";
	
}
