1、新增临时素材,接口java代码:
/** * 文件上传到微信服务器 * @param fileType 文件类型 * @param filePath 文件路径 * @return JSONObject * @throws Exception */ public static JSONObject mediaUpload(String fileType, String filePath) throws Exception { String result = null; File file = new File(filePath); if (!file.exists() || !file.isFile()) { throw new IOException("文件不存在"); } /** * 第一部分 */ URL urlObj = new URL("http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token="+ getAccessToken().getToken() + "&type=" + fileType + ""); HttpURLConnection con = (HttpURLConnection) urlObj.openConnection(); con.setRequestMethod("POST"); // 以Post方式提交表单,默认get方式 con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); // post方式不能使用缓存 // 设置请求头信息 con.setRequestProperty("Connection", "Keep-Alive"); con.setRequestProperty("Charset", "UTF-8"); // 设置边界 String BOUNDARY = "----------" + System.currentTimeMillis(); con.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + BOUNDARY); // 请求正文信息 // 第一部分: StringBuilder sb = new StringBuilder(); sb.append("--"); // 必须多两道线 sb.append(BOUNDARY); sb.append("\r\n"); sb.append("Content-Disposition: form-data;name=\"file\";filename=\"" + file.getName() + "\"\r\n"); sb.append("Content-Type:application/octet-stream\r\n\r\n"); byte[] head = sb.toString().getBytes("utf-8"); // 获得输出流 OutputStream out = new DataOutputStream(con.getOutputStream()); // 输出表头 out.write(head); // 文件正文部分 // 把文件已流文件的方式 推入到url中 DataInputStream in = new DataInputStream(new FileInputStream(file)); int bytes = 0; byte[] bufferOut = new byte[1024]; while ((bytes = in.read(bufferOut)) != -1) { out.write(bufferOut, 0, bytes); } in.close(); // 结尾部分 byte[] foot = ("\r\n--" + BOUNDARY + "--\r\n").getBytes("utf-8");// 定义最后数据分隔线 out.write(foot); out.flush(); out.close(); StringBuffer buffer = new StringBuffer(); BufferedReader reader = null; try { // 定义BufferedReader输入流来读取URL的响应 reader = new BufferedReader(new InputStreamReader( con.getInputStream())); String line = null; while ((line = reader.readLine()) != null) { System.out.println(line); buffer.append(line); } if (result == null) { result = buffer.toString(); } } catch (IOException e) { System.out.println("发送POST请求出现异常!" + e); e.printStackTrace(); throw new IOException("数据读取异常"); } finally { if (reader != null) { reader.close(); } } JSONObject jsonObj = JSONObject.fromObject(result); return jsonObj; }
2、获取access_token代码:
/** * 获取access_token * * @return */ public static AccessToken getAccessToken() { AccessToken accessToken = null; String requestUrl = access_token_url.replace("APPID", WxConstants.APPID).replace("APPSECRET", WxConstants.SECRET); JSONObject jsonObject = httpRequest(requestUrl, "GET", null); // 如果请求成功 if (null != jsonObject) { try { accessToken = new AccessToken(); accessToken.setToken(jsonObject.getString("access_token")); accessToken.setExpiresIn(jsonObject.getInt("expires_in")); } catch (JSONException e) { accessToken = null; // 获取token失败 logger.error("获取token失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg")); } } logger.debug("获取token成功accessToken:--------------------------------------"+accessToken.getToken()); return accessToken; }
3、新增临时素材Controller层代码:
/** * 新增临时素材 */ public void save() { ResultModel rm = new ResultModel(); WxMaterial wxMaterial = new WxMaterial(); String uploadDir = FileTool.getUploadFileDir();//存放目录 String filePath = PathKit.getWebRootPath() + uploadDir; List<UploadFile> files = new ArrayList<UploadFile>(); try{ files = getFiles(filePath,MAXSize); }catch (Exception e) { e.printStackTrace(); rm.setMsg("附件大小必须在2M内"); renderJson(rm); return; } String title = getPara("title"); String uuid = UniqueIDGenerator.getUUID(); try { if(files!=null && files.size()>0){ UploadFile uploadFile = files.get(0); logger.debug("文件路径:"+filePath + "/" + uploadFile.getFileName()); JSONObject mediaUpload = WeixinUtil.mediaUpload(WeixinUtil.MEDIA_UPLOAD_IMAGE_, filePath + "/" + uploadFile.getFileName()); //上传失败 if (mediaUpload == null || (mediaUpload.get("errcode") !=null && 0 != mediaUpload.getInt("errcode"))) { logger.debug("上传文件失败:"+mediaUpload.toString()); }else{ WxMaterialBean wxMaterialBean = (WxMaterialBean)JSONObject.toBean( mediaUpload,WxMaterialBean.class ); //保存文件 String oldFileName=uploadFile.getFileName(); String suffixFile=FileTool.GetExtensionName(oldFileName);// String newFileName=UniqueIDGenerator.getUUID()+"."+suffixFile; boolean upResult=FileTool.RenameFile(filePath,oldFileName,newFileName); String newPath = (uploadDir+File.separator+newFileName).replaceAll("\\\\", "/"); AttachFile attachFile = new AttachFile(); attachFile.set("uuid", uuid); attachFile.set("content_type", uploadFile.getContentType()); attachFile.set("name", newFileName); attachFile.set("old_name", oldFileName); attachFile.set("field_name", uploadFile.getParameterName()); attachFile.set("path", newPath); attachFile.save(); wxMaterial.set("uuid", uuid); wxMaterial.set("title", title); wxMaterial.set("type", wxMaterialBean.getType()); wxMaterial.set("media_id", wxMaterialBean.getMedia_id()); wxMaterial.set("created_at", wxMaterialBean.getCreated_at()); wxMaterial.save(); rm.setMsg("新增素材成功!"); rm.setSuccessCode(); renderJson(rm); logger.debug("后台--新增临时素材成功-------------------"+(wxMaterial==null?"":wxMaterial.toString())); return; } } } catch (Exception e) { e.printStackTrace(); } rm.setFailCode(); rm.setMsg("新增素材失败!"); renderJson(rm); logger.debug("后台--新增临时素材失败-------------------"+(wxMaterial==null?"":wxMaterial.toString())); }
