java开发微信分享到朋友圈功能

微信分享功能开发

用了一天时间，把微信发送给朋友和分享到朋友圈功能开发出来，在这里给大家分享一下，避免大家走弯路。

一、服务器端程序package com.wiimedia.controller;import java.io.IOException;import java.security.MessageDigest;import java.security.NoSuchAlgorithmException;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Arrays;import java.util.Date;

}class ShareAccess_Token{private String access_token;private String expires_in;public String getAccess_token() {return access_token;}public void setAccess_token(String accessToken) {access_token = accessToken;}public String getExpires_in() {return expires_in;}public void setExpires_in(String expiresIn) {expires_in = expiresIn;}}}二、客户端代码.<script type="text/javascript">var url = window.location.href;var articleId = "";var shareTitle="明日医疗资讯";var shareImgUrl="";var userinfo = localStorage.getItem("_userinfo");var timestamp;var noncestr;var signature;//获取签名$.ajax({type: "GET",url: "WeixinshareController/Api/Inteface/getSignature",//data:{timestamp:timestamp,noncestr:noncestr,url:url},data:{url:url},success: function(data){var objData=JSON.parse(data);timestamp=objData.timestamp;noncestr=objData.noncestr;signature=objData.signature;console.log(objData);wxShare();}});function wxShare(){wx.config({debug: false, // 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: '您的appid', // 和获取Ticke的必须一样------必填，公众号的唯一标识timestamp:timestamp, // 必填，生成签名的时间戳nonceStr: noncestr, // 必填，生成签名的随机串signature: signature,// 必填，签名，见附录1jsApiList: ['onMenuShareAppMessage'] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2});}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。//----------“分享给朋友”wx.onMenuShareAppMessage({title: "明日医疗资讯", // 分享标题desc: shareTitle, // 分享描述link: url, // 分享链接imgUrl: shareImgUrl, // 分享图标type: '', // 分享类型,music、video或link，不填默认为linkdataUrl: '', // 如果type是music或video，则要提供数据链接，默认为空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}});//------------"分享到朋友圈"wx.onMenuShareTimeline({title: '明日医疗资讯', // 分享标题link: '', // 分享链接imgUrl: shareImgUrl, // 分享图标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}});//-------------分享到QQwx.onMenuShareQQ({title: '明日医疗资讯', // 分享标题desc: shareTitle, // 分享描述link: '', // 分享链接imgUrl: shareImgUrl, // 分享图标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}});//-------------分享到QQ空间wx.onMenuShareQZone({title: '明日医疗资讯', // 分享标题desc: shareTitle, // 分享描述link: '', // 分享链接imgUrl: shareImgUrl, // 分享图标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}});});三、服务器需要的工具类和Model

① Ticketpackage com.wiimedia.model;public class Ticket{ private String tid; private String ticket;private String errcode; private String errmsg;private String expires_in; private String acquiretime; private String noncestr; private String timestamp;public Ticket(String tid, String ticket, String errcode, String errmsg,String expiresIn, String acquiretime, String noncestr,String timestamp) {super();this.tid = tid;this.ticket = ticket;this.errcode = errcode;this.errmsg = errmsg;expires_in = expiresIn;this.acquiretime = acquiretime;this.noncestr = noncestr;this.timestamp = timestamp; } public String getTid() {return tid; } public void setTid(String tid) {this.tid = tid; } public String getTicket() {return ticket; } public void setTicket(String ticket) {this.ticket = ticket; } public String getErrcode() {return errcode; } public void setErrcode(String errcode) {this.errcode = errcode; } public String getErrmsg() {return errmsg; } public void setErrmsg(String errmsg) {this.errmsg = errmsg; } public String getExpires_in() {return expires_in; } public void setExpires_in(String expiresIn) {expires_in = expiresIn; } public String getAcquiretime() {return acquiretime; } public void setAcquiretime(String acquiretime) {this.acquiretime = acquiretime; } public String getNoncestr() {return noncestr; } public void setNoncestr(String noncestr) {this.noncestr = noncestr; } public String getTimestamp() {return timestamp; } public void setTimestamp(String timestamp) {this.timestamp = timestamp; }}② 添加到数据库的业务根据自己需要进行实现. ③ GetRandomStrpackage com.wiimedia.utils; import java.util.Random; public class GetRandomStr { /****<p>Project:mryl_phone_v2</p>**<p>:mryl_phone_v2</p>**<p>Description:生成随即字符串 </p>**<p>Company:Wiimedia</p>**@Athor:SongJia**@Date:2016-7-14 上午11:14:46**/ public String getRandomString(int length) {String base = "abcdefghijklmnopqrstuvwxyz0123456789";Random random = new Random();StringBuffer sb = new StringBuffer();for (int i = 0; i < length; i++) {int number = random.nextInt(base.length());sb.append(base.charAt(number));}return sb.toString();}} ④ SignatureBeanpackage com.wiimedia.utils; public class SignatureBean { private String noncestr; private String url; private String timestamp; private String signature; public String getNoncestr() {return noncestr; } public void setNoncestr(String noncestr) {this.noncestr = noncestr; } public String getUrl() {return url; } public void setUrl(String url) {this.url = url; } public String getTimestamp() {return timestamp; } public void setTimestamp(String timestamp) {this.timestamp = timestamp; } public String getSignature() {return signature; } public void setSignature(String signature) {this.signature = signature; } }⑤ WeixinUtilpackage com.wiimedia.utils.weixin;import java.io.BufferedReader;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.net.ConnectException;import java.net.URL; import javax.net.ssl.HttpsURLConnection;import javax.net.ssl.SSLContext;import javax.net.ssl.SSLSocketFactory;import javax.net.ssl.TrustManager; /****<p>Project:mryl_phone_v2</p>**<p>:mryl_phone_v2</p>**<p>Description:公众平台接口工具类</p>**<p>Company:Wiimedia</p>**@Athor:SongJia**@Date:2016-7-15 上午09:37:13**/public class WeixinUtil {/*** 发起https请求并获取结果** @param requestUrl 请求地址* @param requestMethod 请求方式（GET、POST）* @param outputStr 提交的数据* @return JSONObject(通过JSONObject.get(key)的方式获取json对象的属性值)*/ public static String httpRequest(String requestUrl, String requestMethod, String outputStr) {StringBuffer buffer = new StringBuffer();try {// 创建SSLContext对象，并使用我们指定的信任管理器初始化TrustManager[] tm = { new MyX509TrustManager() };SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");sslContext.init(null, tm, new java.security.SecureRandom());// 从上述SSLContext对象中得到SSLSocketFactory对象SSLSocketFactory ssf = sslContext.getSocketFactory();URL url = new URL(requestUrl);HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();httpUrlConn.setSSLSocketFactory(ssf);httpUrlConn.setDoOutput(true);httpUrlConn.setDoInput(true);httpUrlConn.setUseCaches(false);// 设置请求方式（GET/POST）httpUrlConn.setRequestMethod(requestMethod);if ("GET".equalsIgnoreCase(requestMethod))httpUrlConn.connect();// 当有数据需要提交时if (null != outputStr) {OutputStream outputStream = httpUrlConn.getOutputStream();// 注意编码格式，防止中文乱码outputStream.write(outputStr.getBytes("UTF-8"));outputStream.close();}// 将返回的输入流转换成字符串InputStream inputStream = httpUrlConn.getInputStream();InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");BufferedReader bufferedReader = new BufferedReader(inputStreamReader);String str = null;while ((str = bufferedReader.readLine()) != null) {buffer.append(str);}bufferedReader.close();inputStreamReader.close();// 释放资源inputStream.close();inputStream = null;httpUrlConn.disconnect();return buffer.toString();} catch (ConnectException ce) {ce.printStackTrace();} catch (Exception e) {e.printStackTrace();}return "";}} 四、至此，分享功能已经开发完成，但是，在生成signature的时候会遇到很多问题，这里提供一些wx.config失败的排错方法。

① 确认自己的生成的signature是否正确 在微信提供的http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=jsapisign进行校验

② wx.config中使用的noncestr, timestamp与用以签名中的对应noncestr, timestamp是否一致一致…如上面（一.服务器代码） （有可能因为JS页面加载顺序问题，服务器生成的signature，noncestr，timestamp在wx.config中没有获取到）。

③ 确认url是页面完整的url，包括GET参数部分 需要去掉#后面的部分

④ config 中的 appid 与用来获取 jsapi_ticket 的 appid 是否一致

⑤ 报错｛errmsg：config:ok}是debug的正常返回把调试模式关掉就OK wx.config debug: false,
