企业微信获取JS

前言

注意:
1.corpid是企业微信的ID， corpsecret是应用程序的；需要应用配置网页授权可信任域名，下载完文件后，把已下载的文件放置到域名根目录下（需要管理员权限，查看文档具体说明。）
2.小程序获取方法其实是一样的，只是地址不一样，可以看一下微信文档说明。

1.企业微信获取access_token
=corpid&corpsecret=corpsecret

/*** 企业微信access_token* @return*/public static String getQyAccess_token() throws Exception {String nowtime = DateHelper.getNow();//小于半个小时直接返回之前的 qywx_accesstokenif(StringHelper.isNotEmpty(qywx_accesstoken) && DateHelper.getDateSecond(qywx_accesstokentime,nowtime)<1800){return qywx_accesstoken;}qywx_accesstokentime = nowtime;HttpURLConnection conn = null;InputStreamReader inputStreamReader = null;BufferedReader bufferedReader = null;JSONObject jsonObject = null;try {String url = "="+CORPID+"&corpsecret="+CORPSECRET;URL u = new URL(url);conn = (HttpURLConnection) u.openConnection();conn.setRequestMethod("GET");conn.connect();inputStreamReader = new InputStreamReader(conn.getInputStream(), "utf-8");bufferedReader = new BufferedReader(inputStreamReader);String str = null;StringBuffer buffer = new StringBuffer();while ((str = bufferedReader.readLine()) != null) {buffer.append(str);}jsonObject = JSONObject.fromObject(buffer.toString());String access_token = jsonObject.getString("access_token");//System.out.println("----------------------Access_token---------------------------" + access_token);return access_token;} catch (Exception e) {System.out.println("----------------------Access_tokenError---------------------------" + jsonObject);e.printStackTrace();} finally {try {// 释放资源if (bufferedReader != null) {bufferedReader.close();}if (inputStreamReader != null) {inputStreamReader.close();}if (conn != null) {conn.disconnect();}} catch (Exception e) {e.printStackTrace();}}return null;}

2.获取jsticket
=access_token

/*** 获取jsticket的执行体** @param access_token* @return*/public static String getTicket(String access_token) throws Exception {String nowtime = DateHelper.getNow();//小于半个小时直接返回之前的 ticketif(StringHelper.isNotEmpty(ticket) && DateHelper.getDateSecond(ticket_time,nowtime)<1800){return ticket;}ticket_time = nowtime;HttpURLConnection conn = null;InputStreamReader inputStreamReader = null;BufferedReader bufferedReader = null;JSONObject jsonObject = null;try {String getticket = "="+access_token;String url = String.format(getticket, APPID, APPSECRET);URL u = new URL(url);conn = (HttpURLConnection) u.openConnection();conn.setRequestMethod("GET");conn.connect();inputStreamReader = new InputStreamReader(conn.getInputStream(), "utf-8");bufferedReader = new BufferedReader(inputStreamReader);String str = null;StringBuffer buffer = new StringBuffer();while ((str = bufferedReader.readLine()) != null) {buffer.append(str);}jsonObject = JSONObject.fromObject(buffer.toString());String ticket = jsonObject.getString("ticket");System.out.println("----------------------ticket---------------------------" + ticket);return ticket;} catch (Exception e) {System.out.println("----------------------ticketError---------------------------" + jsonObject);e.printStackTrace();} finally {try {// 释放资源if (bufferedReader != null) {bufferedReader.close();}if (inputStreamReader != null) {inputStreamReader.close();}if (conn != null) {conn.disconnect();}} catch (Exception e) {e.printStackTrace();}}return null;}

3.获取前端jssdk页面配置需要用到的配置参数

/*** 前端jssdk页面配置需要用到的配置参数** @param url* @param ticket* @return* @throws Exception*/public static Map<String, String> getSignature(String url, String ticket,String appid) throws Exception {String noncestr = UUID.randomUUID().toString();String timestamp = Long.toString(System.currentTimeMillis() / 1000);// 注意这里参数名必须全部小写，且必须有序String string1 = "jsapi_ticket=" + ticket +"&noncestr=" + noncestr +"&timestamp=" + timestamp +"&url=" + url;MessageDigest crypt = MessageDigest.getInstance("SHA-1");crypt.reset();crypt.update(string1.getBytes("UTF-8"));String signature = byteToHex(crypt.digest());HashMap<String, String> jssdk = new HashMap<String, String>();jssdk.put("appId", appid);jssdk.put("timestamp", timestamp);jssdk.put("nonceStr", noncestr);jssdk.put("signature", signature);return jssdk;}private static String byteToHex(final byte[] hash) {Formatter formatter = new Formatter();for (byte b : hash) {formatter.format("%02x", b);}String result = formatter.toString();formatter.close();return result;}

4.获取微信临时素材
=access_token&media_id=mediaId

/*** 获取微信临时素材** @param mediaId* @return*/public static InputStream downloadMedia(String access_token, String mediaId) {URLConnection conn = null;InputStream is = null;BufferedInputStream bis = null;String fileSize = "";try {String requestUrl = "="+access_token+"&media_id="+mediaId;URL realUrl = new URL(requestUrl);conn = realUrl.openConnection();conn.setRequestProperty("accept", "*/*");conn.setRequestProperty("connection", "Keep-Alive");conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");conn.setRequestProperty("Content-Type",  "application/x-www-form-urlencoded; charset=utf-8");conn.setRequestProperty("Accept-Charset", "UTF-8"); //conn.setRequestProperty("contentType", "utf-8");//获取网络流的头部信息Map<String, List<String>> maps = conn.getHeaderFields();for (String key : maps.keySet()) {System.out.println(key + "---> " + maps.get(key));if ("Content-Length".equals(key)) {fileSize = maps.get(key).get(0);//获取文件大小}}// 获取网络流的内容bis = new BufferedInputStream(conn.getInputStream());byte[] data = getByte(bis); // 获取当前条目的字节数组is = new ByteArrayInputStream(data); // 把当前条目的字节数据转换成Inputstream流return is ;} catch (Exception e) {e.printStackTrace();return null;} finally {if (bis != null) {try {bis.close();} catch (IOException e) {e.printStackTrace();}}if (is != null) {try {is.close();} catch (IOException e) {e.printStackTrace();}}}}/*** 获取条目byte[]字节** @param is* @return*/public static byte[] getByte(InputStream is) {try {ByteArrayOutputStream bout = new ByteArrayOutputStream();byte[] temp = new byte[1024];byte[] buf = null;int length = 0;while ((length = is.read(temp, 0, 1024)) != -1) {bout.write(temp, 0, length);}buf = bout.toByteArray();bout.close();return buf;} catch (IOException e) {e.printStackTrace();return null;}}
