新增临时素材

前面有些地方其实已经调用这个，为了得到media_id。
请求参数中type是媒体文件类型，分别有图片（image）、语音（voice）、视频（video）和缩略图（thumb）。
以图片类型为例：

		// 先获取access_token，这部分正式环境需要配置定时获取，每天2000次调用限制String url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" + APPID + "&secret=" + SECRET;String result = Jsoup.connect(url).ignoreContentType(true).method(Method.GET).execute().body();System.out.println(result);String accessToken = JSON.parseObject(result).getString("access_token");// 新增临时素材url = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=" + accessToken + "&type=image";File file = new File("D:/1.jpg");result = Jsoup.connect(url).ignoreContentType(true).method(Method.POST).data("media", file.getName(), new FileInputStream(file)).timeout(60000).execute().body();// {"type":"image","media_id":"1pd6iWTtkWfMd-BZX9I3a4Tm6kHiJlPhbzFKNMUyQUArfAKlKAXaVEwUOK-3LsMe","created_at":1670570665,"item":[]}System.out.println(result);

返回数据样例：

{  
"type":"image",  
"media_id":"1pd6iWTtkWfMd-BZX9I3a4Tm6kHiJlPhbzFKNMUyQUArfAKlKAXaVEwUOK-3LsMe",  
"created_at":1670570665,  
"item":[  ]  
}

获取临时素材

获取临时素材分为视频类和非视频类，获取到的格式不一样。如果是非视频类，直接接收到素材文件，本地保存使用即可。如果是视频类的，返回的是视频的url，本地可以对这个url进行继续操作。
视频类的比较简单，下面介绍下非视频类获取到文件后进行保存。

		// 获取临时素材（非视频类）String savePath = "D:/11.jpg"; //保存下来的文件路径和名称String mediaId = JSON.parseObject(result).getString("media_id");url = " https://api.weixin.qq.com/cgi-bin/media/get?access_token=" + accessToken + "&media_id=" + mediaId;Response response = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.GET).execute();if(response.statusCode() == 200) {BufferedInputStream bufferedInputStream = response.bodyStream();byte[] buffer = new byte[1024];int len = 0;FileOutputStream fileOutStream = new FileOutputStream(new File(savePath));BufferedOutputStream bufferedOut = new BufferedOutputStream(fileOutStream);while ((len = bufferedInputStream.read(buffer, 0, 1024)) != -1) {bufferedOut.write(buffer, 0, len);}bufferedOut.flush();bufferedOut.close();System.out.println("保存完成：" + savePath);}// 如果是视频文件，用下面的方式
//		result = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.GET).execute().body();
//		// 视频返回格式：{ "video_url":DOWN_URL }
//		System.out.println(result);

上传图文消息内的图片

这里会得到一个图片的url，用来插入到图文消息内。 直接使用外部的图片url是不能成功在素材内显示的。

		// 上传图文消息内的图片获取URL。 这个url只能腾讯系域名内使用，其他地方用会被屏蔽url = "https://api.weixin.qq.com/cgi-bin/media/uploadimg?access_token=" + accessToken;file = new File("D:/1.jpg");result = Jsoup.connect(url).ignoreContentType(true).method(Method.POST).data("media", file.getName(), new FileInputStream(file)).timeout(60000).execute().body();// {"url":"http:\/\/mmbiz.qpic.cn\/mmbiz_png\/B2O8ZzVDiaBJb8ia9UylXQZHtyBfH88hmLbdGsV343SFUdD1I04jCxsMQ0lLgJrUNj0Htrx9fUHrjMvB9fKgaV5Q\/0"}System.out.println(result);

返回的就是一个url，样例：

{  
"url":"http://mmbiz.qpic.cn//mmbiz_png//B2O8ZzVDiaBJb8ia9UylXQZHtyBfH88hmLbdGsV343SFUdD1I04jCxsMQ0lLgJrUNj0Htrx9fUHrjMvB9fKgaV5Q//0"  
}

新增永久素材

新增永久素材分为视频类和其他类。如果是视频类，需要指定描述信息，包括视频标题和视频介绍，而诸如图片类则不需要上传这些。
非视频类新增永久素材样例：

		// 新增永久素材（非视频）url = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=" + accessToken + "&type=image";file = new File("D:/1.jpg");result = Jsoup.connect(url).ignoreContentType(true).method(Method.POST).data("media", file.getName(), new FileInputStream(file)).timeout(60000).execute().body();// {"media_id":"6XvVazVT3F4qsVQ-QW23lhD2JFBCpOayJVKEUvR2T24XVLvTSVTYjbfT038ErTyW","url":"http:\/\/mmbiz.qpic.cn\/mmbiz_png\/B2O8ZzVDiaBJb8ia9UylXQZHtyBfH88hmLbdGsV343SFUdD1I04jCxsMQ0lLgJrUNj0Htrx9fUHrjMvB9fKgaV5Q\/0?wx_fmt=png","item":[]}System.out.println(result);

视频类新增永久素材

		// 新增永久素材（视频）param = new JSONObject();param.put("title", "视频标题");param.put("introduction", "视频介绍");url = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=" + accessToken + "&type=video";file = new File("D:/1.mp4");result = Jsoup.connect(url).ignoreContentType(true).method(Method.POST).data("media", file.getName(), new FileInputStream(file)).data("description", param.toString()).timeout(60000).execute().body();// {"media_id":"6XvVazVT3F4qsVQ-QW23lqhl-X1EKmke5-oeZM969ckNHqNnfngWltCamzmXP-PW","url":"http:\/\/mmbiz.qpic.cn\/mmbiz_png\/B2O8ZzVDiaBJb8ia9UylXQZHtyBfH88hmLbdGsV343SFUdD1I04jCxsMQ0lLgJrUNj0Htrx9fUHrjMvB9fKgaV5Q\/0?wx_fmt=png","item":[]}System.out.println(result);

获取永久素材

非视频类的永久素材获取到的是文件，可以直接保存；如果是视频类的，得到的是视频的url，可以本地对此url进行操作。
非视频类获取永久素材样例：

		// 获取永久素材（非视频）savePath = "D:/111.jpg"; //保存下来的文件路径和名称mediaId = JSON.parseObject(result).getString("media_id");url = " https://api.weixin.qq.com/cgi-bin/material/get_material?access_token=" + accessToken;JSONObject param = new JSONObject();param.put("media_id", mediaId);response = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.POST).requestBody(param.toString()).execute();if(response.statusCode() == 200) {BufferedInputStream bufferedInputStream = response.bodyStream();byte[] buffer = new byte[1024];int len = 0;FileOutputStream fileOutStream = new FileOutputStream(new File(savePath));BufferedOutputStream bufferedOut = new BufferedOutputStream(fileOutStream);while ((len = bufferedInputStream.read(buffer, 0, 1024)) != -1) {bufferedOut.write(buffer, 0, len);}bufferedOut.flush();bufferedOut.close();System.out.println("保存完成：" + savePath);}

视频类获取永久素材样例：

		// 获取永久素材（视频）savePath = "D:/222.mp4"; //保存下来的文件路径和名称mediaId = JSON.parseObject(result).getString("media_id");param = new JSONObject();param.put("media_id", mediaId);url = "https://api.weixin.qq.com/cgi-bin/material/get_material?access_token=" + accessToken;result = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.POST).requestBody(param.toString()).execute().body();// {"title":"视频标题","description":"","down_url":"http:\/\/203.205.136.93\/vweixinp.tc.qq.com\/1007_5e87b6d9116d4cb6b6f950f9f112e0da.f10.mp4?vkey=0DCBE63134C59AEF366ABD98224872C7AB274D10F3E261786B1FBC32218428CCC988FE097350FA214526F1671AF7E20C6CDE776EA209D01EFBA9635BED58CA095BECE78045E1FAC2DAD94B1CCDB35D5068FAB4FC0E83BA81&sha=0&save=1","newcat":"","newsubcat":"","tags":[],"cover_url":"","vid":"1007_5e87b6d9116d4cb6b6f950f9f112e0da"}System.out.println(result);

删除永久素材

这个就比较简单了，直接上样例：

		// 删除永久素材param = new JSONObject();param.put("media_id", mediaId);url = "https://api.weixin.qq.com/cgi-bin/material/del_material?access_token=" + accessToken;result = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.POST).requestBody(param.toString()).execute().body();// {"errcode":0,"errmsg":"ok"}System.out.println(result);

获取素材总数

获取到的总数有四种
voice_count语音总数量
video_count视频总数量
image_count图片总数量
news_count图文总数量

		// 获取素材总数url = "https://api.weixin.qq.com/cgi-bin/material/get_materialcount?access_token=" + accessToken;result = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.GET).execute().body();// {"voice_count":0,"video_count":5,"image_count":33,"news_count":0}System.out.println(result);

获取素材列表

需要根据素材类型进行请求，每次最多获取20条。

		// 获取素材列表param = new JSONObject();param.put("type", "video"); //素材的类型，图片（image）、视频（video）、语音 （voice）、图文（news）param.put("offset", "0"); //从全部素材的该偏移位置开始返回，0表示从第一个素材 返回param.put("count", "20"); //返回素材的数量，取值在1到20之间url = "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=" + accessToken;result = Jsoup.connect(url).ignoreContentType(true).maxBodySize(0).method(Method.POST).requestBody(param.toString()).execute().body();// {"item":[{"media_id":"6XvVazVT3F4qsVQ-QW23ll5Hl3mPk-BZvPZ6q9nUWnL4_E0m9JXdri6nCfTYZ3HG","name":"视频标题","update_time":1670575041,"description":"","tags":[]},{"media_id":"6XvVazVT3F4qsVQ-QW23llrmr7VBAtByYbUdOmuDF1S7FPEwVWuctCZ8QsO94NqP","name":"视频标题","update_time":1670574857,"description":"","tags":[]},{"media_id":"6XvVazVT3F4qsVQ-QW23loB2h52KHMEeNva8B-HQ6j3-geb2yzADAr83hXqbkqVt","name":"视频标题","update_time":1670574820,"description":"","tags":[]},{"media_id":"6XvVazVT3F4qsVQ-QW23lqiC159B12i-Iy_1404_AFhsEcWsuvxlKC1GLsYrKk0c","name":"视频标题","update_time":1670574735,"description":"","tags":[]},{"media_id":"6XvVazVT3F4qsVQ-QW23lhZjulUCZMHWn5eRyL69G8spweQ-CEfvW57HyiFA8c2y","name":"视频","update_time":1663818592,"cover_url":"http:\/\/mmbiz.qpic.cn\/mmbiz_jpg\/B2O8ZzVDiaBLDFUvZQZr8Mpp3iaIzNrO6aQ9tkPgibOQqwFtTMbglDywRiaSf4HPqa5ibwjhGVFMHZMtxYmdaLcYHyQ\/0?wx_fmt=jpeg","description":"","newcat":"搞笑","newsubcat":"其他","tags":[],"vid":"wxv_2587487411262275585"}],"total_count":5,"item_count":5}System.out.println(result);
