java weixin.mp 怎么上传素材

微信公众号先上传素材,再推送消息java代码实现:

首先公众号的图文消息是可以登录公众号,然后去管理--素材管理下面去手动添加图文,图片,视频,音乐素材的.这样添加的素材属于永久素材.

用java代码实现的时候,很多人报错无效的media_id, 或无效的thumb_media_id,那是因为你上传的素材是临时的,换成永久id就可以了.

以下是我的几个亲测可用的Test. 具体的需求请参考官方文档 https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1481187827_i0l21

1.获取素材列表


package weixin.tuwen;
 
import java.io.IOException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.util.HashMap;
import java.util.Map;
 
import weixin.tuwen.pojo.Material;
import weixin.util.WX_HttpsUtil;
import weixin.util.WX_TokenUtil;
import com.alibaba.fastjson.JSONObject;
import com.qs.util.HttpsPostUtil;
import com.qs.util.httpspost.HttpsUtil;
 
public class TestGetSucaiList {
 
	/**
	 * 获取永久素材列表(根据分类)
	 * 图片（image）、视频（video）、语音 （voice）、图文（news）
	 * 参数:type   offset    count
	 * @throws IOException 
	 * @throws NoSuchAlgorithmException 
	 * @throws KeyManagementException 
	 */
	public static void main(String[] args) throws KeyManagementException, NoSuchAlgorithmException, IOException {
		String access_token = WX_TokenUtil.getWXToken().getAccessToken();
		String url = "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token="+access_token;
		//POST请求发送的json参数
		Material m = new Material();
		m.setType("news");
		m.setOffset(0);
		m.setCount(10);
		JSONObject json = (JSONObject) JSONObject.toJSON(m);
		String str = json.toString();
		System.out.println(str);
//		Map<String,String> createMap = new HashMap<String,String>();  
//		createMap.put("type","image");  
//		createMap.put("offset","0");  
//		createMap.put("count","1");
		byte[] result = HttpsUtil.post(url, str, "utf-8");
		String strs = new String(result);
		System.out.println(strs);
	}
 
}

2.上传音乐素材到公众号 (有需要上传图片的,请自行把参数替换掉)


package weixin.tuwen;
 
import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.File;

import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
 
import net.sf.json.JSONObject;
 
import weixin.util.WX_TokenUtil;
 
public class UploadSucai {
 
	/**
	 * @param args
	 * 上传音乐到公众号
	 * 请求地址(post):https://api.weixin.qq.com/cgi-bin/media/uploadnews?access_token=ACCESS_TOKEN
	 */
	public static void main(String[] args) {
		String access_token = WX_TokenUtil.getWXToken().getAccessToken();
		File file = new File("C:/Users/v_yiqqin/Music/asdasd.mp3");
		uploadPermanentMedia2(access_token,file,"测试标题","测试描述");
		
	}
	
	
	/** 
     * 这里说下，在上传视频素材的时候，微信说不超过20M，我试了下，超过10M调通的可能性都比较小，建议大家上传视频素材的大小小于10M比交好

3.上传临时或者永久缩略图素材 (注释掉的地址是临时素材的)


package weixin.tuwen;
 
import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
 
import net.sf.json.JSONObject;
import weixin.util.WX_TokenUtil;
 
public class UploadLinshiSucai {
		//临时素材地址
//	    private static final String UPLOAD_URL = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE";
	    //永久素材的地址
	    private static final String UPLOAD_URL = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=ACCESS_TOKEN&type=TYPE";
	    public static String uploadFile(File file, String accessToken, String type) throws Exception{
//	        File file = new File(filePath);
	        if(!file.exists() || !file.isFile()) {
	            throw new IOException("文件不存在！");
	        }
 
	        String url = UPLOAD_URL.replace("ACCESS_TOKEN", accessToken).replace("TYPE", type);
	        URL urlObj = new URL(url);
 
	        //连接
	        HttpURLConnection conn = (HttpURLConnection) urlObj.openConnection();
 
	        conn.setRequestMethod("POST");

	        //输出流
	        OutputStream out = new DataOutputStream(conn.getOutputStream());
 
	        out.write(head);
 
	        //文件正文部分
	        DataInputStream in = new DataInputStream(new FileInputStream(file));
	        int bytes = 0;
	        byte[] bufferOut = new byte[1024];
	        while((bytes = in.read(bufferOut))!=-1) {

	        out.write(foot);
	        out.flush();
	        out.close();
 
	        //获取响应
	        StringBuffer buffer = new StringBuffer();
	        BufferedReader reader = null;
	        String result = null;
 
	        reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
	        String line = null;
	        while((line = reader.readLine()) != null) {
	            buffer.append(line);
	        }
	        if(result == null) {
	            result = buffer.toString();
	        }
	        reader.close();
 
	        //需要添加json-lib  jar包
	        JSONObject json = JSONObject.fromObject(result);
	        System.out.println(json);
	        String mediaId = json.getString("thumb_media_id");
 
	        return mediaId;
	    }
	    
	    
		public static void main(String[] args) throws Exception {
			String access_token = WX_TokenUtil.getWXToken().getAccessToken();
			File file = new File("C:/Users/Music/timg.jpg");
			String type = "thumb";
			uploadFile(file,access_token,type);
		}
 
 
}

4.上传图文消息素材


package weixin.tuwen;
 
import java.io.IOException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
 
import com.alibaba.fastjson.JSONObject;
import com.qs.util.httpspost.HttpsUtil;
 
import weixin.tuwen.pojo.Tuwen;
import weixin.util.WX_TokenUtil;
 
/**
 * 上传图文消息素材【订阅号与服务号认证后均可用】
 *  http请求方式: POST
	https://api.weixin.qq.com/cgi-bin/media/uploadnews?access_token=ACCESS_TOKEN
 * @author v_yiqqin
 */
public class TuwenUpload {
	
	
	public static void main(String[] args) throws KeyManagementException, NoSuchAlgorithmException, IOException{
	
		String access_token = WX_TokenUtil.getWXToken().getAccessToken();
//		System.out.println(access_token);
//		String url = "https://api.weixin.qq.com/cgi-bin/media/uploadnews?access_token="+access_token;
		//永久素材地址
		String url = "https://api.weixin.qq.com/cgi-bin/material/add_news?access_token="+access_token;
		Tuwen tt = new Tuwen();
		tt.setThumb_media_id("aprI7dnR4XeWcPEJcjLeIUjcDJv658pne4-2FUzEb6A");
		tt.setAuthor("kevin");
		tt.setTitle("图文测试66666");
		tt.setContent_source_url("www.baidu.com");
		tt.setContent("测试内容666666");
		tt.setDigest("描述666666");
		tt.setShow_cover_pic(1);
		
		JSONObject json = (JSONObject) JSONObject.toJSON(tt);
		String str = json.toString();
		str = "{"+"\"articles\":["+str+"]"+"}";
		byte[] result = HttpsUtil.post(url, str, "utf-8");
		String strs = new String(result);
		System.out.println(strs);
	}
}

5.最后一步,发送图文消息


package weixin.tuwen;
 
import java.io.IOException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.util.List;
 
import com.alibaba.fastjson.JSONObject;
import com.qs.util.httpspost.HttpsUtil;
 
import weixin.tuwen.pojo.GetUserList;
import weixin.tuwen.pojo.Media_id;
import weixin.tuwen.pojo.SendPojo;
import weixin.tuwen.pojo.Text;
import weixin.util.WX_TokenUtil;
 
public class SendMessage {
 
	/**
	 * @param args
	 * @throws IOException 
	 * @throws NoSuchAlgorithmException 
	 * @throws KeyManagementException 
	 */
	public static void main(String[] args) throws KeyManagementException, NoSuchAlgorithmException, IOException {
		String access_token = WX_TokenUtil.getWXToken().getAccessToken();
		String url = "https://api.weixin.qq.com/cgi-bin/message/mass/send?access_token="+access_token;
		//先获取用户openid列表
		List userList = GetUserList.getUserList();
		String openid = userList.toString();
		System.out.println(openid);
		Media_id m = new Media_id();
		m.setMedia_id("aprI7dnR4XasdsafdghjewetrsdKiawoXw6RFzGM");
		JSONObject json1 = (JSONObject) JSONObject.toJSON(m);
		String str1 = json1.toString();
		System.out.println(str1);
		//封装请求参数
		SendPojo sp = new SendPojo();
		sp.setTouser(userList);
		sp.setMpnews(str1);
		sp.setMsgtype("mpnews");
		sp.setSend_ignore_reprint(0);
		
 
		
//		Text t = new Text();
//		t.setContent("hello from boxer");
//		JSONObject json1 = (JSONObject) JSONObject.toJSON(t);
//		String str1 = json1.toString();
//		System.out.println(str1);
//		
//		SendPojo sp = new SendPojo();
//		sp.setTouser(userList);
//		sp.setMsgtype("text");
//		sp.setText(str1);
//		
		JSONObject json = (JSONObject) JSONObject.toJSON(sp);
		String str = json.toString();
		str= str.replace("\\", "");  
		str= str.replace("\"{", "{");
		str= str.replace("}\"", "}");
		System.out.println(str);
		
		byte[] result = HttpsUtil.post(url, str, "utf-8");
		String strs = new String(result);
		System.out.println(strs);
	}
 
}

6.获取用户列表(群发用户)


package weixin.tuwen.pojo;
 
import java.util.List;
 
import com.alibaba.fastjson.JSONObject;
 
import weixin.util.WX_HttpsUtil;
import weixin.util.WX_TokenUtil;
 
public class GetUserList {
 
	/**
	 * @param args
	 */
	public static List getUserList() {
		String access_token = WX_TokenUtil.getWXToken().getAccessToken();
		String url = "https://api.weixin.qq.com/cgi-bin/user/get?access_token="+access_token;
		JSONObject result = WX_HttpsUtil.httpsRequest(url, "GET",null);
		JSONObject resultJson = new JSONObject(result);
		JSONObject data = (JSONObject) resultJson.get("data");
		List openidlist = (List) data.get("openid");
		return openidlist;
	}
 
}
