This article introduces the custom WeChat sharing function of WeChat JS-SDK, which has certain reference value. Now I share it with everyone. Friends in need can refer to it
1 Preparation
appId public account id, apply for sharing interface, ip whitelist setting, JS interface security domain name setting (must be registered)
2. Introduce js
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
3. Inject permission verification configuration through the config interface
wx.config({ debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。 appId: '', // 必填,公众号的唯一标识 timestamp: , // 必填,生成签名的时间戳 nonceStr: '', // 必填,生成签名的随机串 signature: '',// 必填,签名,见附录1 jsApiList: [ 'onMenuShareTimeline', 'onMenuShareAppMessage' , 'onMenuShareQQ' ] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2 });
4. Process through the ready interface Successful verification
wx.ready(function(){ // config信息验证后会执行ready方法,所有接口调用都必须在config接口获得结果之后,config是一个客户端的异步操作,所以如果需要在页面加载时就调用相关接口, 则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口,则可以直接调用,不需要放在ready函数中。 });
5. Handle failed verification through the error interface
wx.error(function(res){ // config信息验证失败会执行error函数,如签名过期导致验证失败,具体错误信息可以打开config的debug模式查看,也可以在返回的res参数中查看,对于SPA可以在这里更新签名。 });
Page source code:
wx.config({ debug: false, appId: 'xxxxxxxxxxxxxx', timestamp: timestamp, nonceStr: nonceStr, signature: signature, jsApiList: [ 'onMenuShareTimeline', 'onMenuShareAppMessage' , 'onMenuShareQQ' ] }); wx.ready(function(){ // wx.hideOptionMenu(); wx.onMenuShareTimeline({ title: '', link: '', imgUrl: '', success: function () { // 用户确认分享后执行的回调函数 //alert('分享到朋友圈成功'); }, cancel: function () { // 用户取消分享后执行的回调函数 //alert('你没有分享到朋友圈'); } }); wx.onMenuShareAppMessage({ title: '', desc: '', link: '', imgUrl: '', trigger: function (res) { // 不要尝试在trigger中使用ajax异步请求修改本次分享的内容,因为客户端分享操作是一个同步操作,这时候使用ajax的回包会还没有返回 }, success: function (res) { //alert('分享给朋友成功'); }, cancel: function (res) { //alert('你没有分享给朋友'); }, fail: function (res) { alert(JSON.stringify(res)); } }); wx.onMenuShareQQ({ title: '', desc: '', link: '', imgUrl: '', success: function () { // 用户确认分享后执行的回调函数 }, cancel: function () { // 用户取消分享后执行的回调函数 } }); });
java code obtains WeChat’s signature, timestamp, and signature random string
url is your current address, WeChat generates token
@RequestMapping("/doGetWxToken") public RespBean<Map<String,Object>> doEditAccractMemberStatus(String url) throws Except ion{ RespBean<Map<String,Object>> resp = new RespBean<Map<String,Object>> (); Map<String,Object> map = new HashMap<String,Object>(); String str = SendGET("https://api.weixin.qq.com/cgi-bin/token", "grant_type=client_ credential&appid=XX&secret=XXXX"); String a = str.substring(str.indexOf("{"), str.indexOf("}")+1); JSONObject jo = JSON.parseObject(a); String token = jo.getString("access_token");//获取token String info = SendGET("https://api.weixin.qq.com/cgi-bin/ticket/getticket", "access _token="+token+"&type=jsapi"); JSONObject ticketO = JSON.parseObject(info); String ticket = ticketO.getString("ticket");//获取ticket Map<String, String> ret = WxSign.sign(ticket, url); for (Map.Entry entry : ret.entrySet()) { System.out.println(entry.getKey() + "=" + entry.getValue()); map.put(entry.getKey().toString(), entry.getValue()); } resp.setBody(map); return resp; } //直接java访问拿对应的数据 public static String SendGET(String url,String param){ String result="";//访问返回结果 BufferedReader read=null;//读取访问结果 try { //创建url URL realurl=new URL(url+"?"+param); //打开连接 URLConnection connection=realurl.openConnection(); // 设置通用的请求属性 connection.setRequestProperty("accept", "*/*"); connection.setRequestProperty("connection", "Keep-Alive"); connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)"); //建立连接 connection.connect(); // 获取所有响应头字段 Map<String, List<String>> map = connection.getHeaderFields(); // 遍历所有的响应头字段,获取到cookies等 for (String key : map.keySet()) { System.out.println(key + "--->" + map.get(key)); } // 定义 BufferedReader输入流来读取URL的响应 read = new BufferedReader(new InputStreamReader( connection.getInputStream(),"UTF-8")); String line;//循环读取 while ((line = read.readLine()) != null) { result += line; } } catch (IOException e) { e.printStackTrace(); }finally{ if(read!=null){//关闭流 try { read.close(); } catch (IOException e) { e.printStackTrace(); } } } return result; }through the current address
