微信js-sdk实现“分享到朋友圈”和“发送给朋友”

时间：2022-02-28 14:19:06

微信接口文档地址：https://mp./wiki?t=resource/res_main&id=mp1421141115&token=&lang=zh_CN

实现步骤：

1.绑定域名

先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。（特别提示不需要加上http或者https,吃过亏）

2.页面引入js文件

3.通过config接口注入权限验证配置

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: [] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2

});

4.通过ready接口处理成功验证

wx.ready(function(){

//详细代码

});

5.通过error接口处理失败验证

wx.error(function(res){});

详细页面代码

java后台action代码：

//微信分享public void shareToFriend(){HttpServletRequest request = ServletActionContext.getRequest();String timeStamp = Sha1Util.getTimeStamp();//时间戳String nonceStr = WxConfig.getUUID();//随机字符串，不长于32位String url=request.getParameter("url");String signature = WxConfig.getSignature("APPId", "APP_secret", url, timeStamp, nonceStr);request.setAttribute("timeStamp", timeStamp);request.setAttribute("nonceStr", nonceStr);request.setAttribute("url", url);request.setAttribute("signature", signature);WXjssdk result = new WXjssdk(timeStamp,nonceStr,signature,url);CommonUtil.returnMsg(ServletActionContext.getResponse(), new Gson().toJson(result));}

WxConfig.java代码

<pre name="code" class="java">//jsapi_ticketpublic final static String WEIXIN_JSAPI_TICKET_URL ="https://api./cgi-bin/ticket/getticket?access_token=ACCESS_TOKEN&type=jsapi";//access_token public static String getAccessToken(String appId,String appSecret){String access_token;access_token = mapToken.get("accessToken");if(access_token==null){String url = HttpUtil.WEIXIN_HOST_API + "/cgi-bin/token?grant_type=client_credential&appid="+appId+"&secret="+appSecret;String menuJsonStr = HttpUtil.get(url);final Type type = new TypeToken<Map<String, Object>>() {}.getType();final Map<Object, Object> accessTokenInfo = new Gson().fromJson(menuJsonStr, type);try{access_token = accessTokenInfo.get("access_token").toString();Object expires_in = accessTokenInfo.get("expires_in");mapToken.put("accessToken", access_token);logger.info("access_token:"+access_token+";expires_in:"+expires_in);}catch (JSONException e) {access_token = null;e.printStackTrace();logger.error("errcode:{}:"+accessTokenInfo.get("errcode")+"errmsg:{}:"+accessTokenInfo.get("errmsg"));}}return access_token;}//jsapi_ticketpublic static String getJsapiTicket(String accessToken){String ticket;ticket = mapTicket.get("ticket");if(ticket==null){String url = HttpUtil.WEIXIN_HOST_API + "/cgi-bin/ticket/getticket?access_token="+accessToken+"&type=jsapi";String menuJsonStr = HttpUtil.get(url);final Type type = new TypeToken<Map<String, Object>>() {}.getType();final Map<Object, Object> ticketInfo = new Gson().fromJson(menuJsonStr, type);try{ticket = ticketInfo.get("ticket").toString();String expires_in = ticketInfo.get("expires_in").toString();mapTicket.put("ticket", ticket);logger.info("jsapi_ticket:"+ticket+";expires_in:"+expires_in);}catch (JSONException e) {ticket = null;e.printStackTrace();logger.error("ticket errcode:{}:"+ticketInfo.get("errcode")+"errmsg:{}:"+ticketInfo.get("errmsg"));}}return ticket;}//生成随机字符串UUIDpublic static String getUUID(){ String uuid = UUID.randomUUID().toString().trim().replaceAll("-", ""); return uuid; } //JS-SDK Signaturepublic static String getSignature(String appId,String appSecret,String url,String timeStamp,String nonceStr){String accessToken = getAccessToken(appId,appSecret);String jsapi_ticket = getJsapiTicket(accessToken);logger.info("accessToken==="+accessToken);String signValue = "jsapi_ticket="+jsapi_ticket+"&noncestr="+nonceStr+"×tamp="+timeStamp+"&url="+url;logger.info("微信JS-SDK权限验证的签名串："+signValue);//这个签名.主要是给加载微信js使用.别和上面的搞混了.String signature = Sha1Util.getSha1((signValue));logger.info("微信JS-SDK权限验证的签名："+signature);return signature;}

另外项目用到的

Sha1Util.java和MD5Util.java可以直接在平台下载。
