微信分享功能開發
用了一天時間，把微信發送給朋友和分享到朋友圈功能開發出來，在這裡給大家分享一下，避免大家走彎路。
一、服務器端程序

} 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、客戶端代碼.
<script type="text/javascript"> var url = window.location.href; var articleId = ""; var shareTitle="明日醫療資訊"; var shareImgUrl=""; var userinfo = localStorage.getItem("_userinfo"); var timestamp; var noncestr; var signature; //獲取簽名$.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, // 開啟調試模式,調用的所有api的返回值會在客戶端alert出來，若要查看傳入的參數，可以在pc端打開，參數信息會通過log打出，僅在pc端時才會打印。 appId: '您的appid', // 和獲取Ticke的必須一樣------必填，公眾號的唯一標識timestamp:timestamp, // 必填，生成簽名的時間戳nonceStr: noncestr, // 必填，生成簽名的隨機串signature: signature,// 必填，簽名，見附錄1 jsApiList: [ 'onMenuShareAppMessage' ] // 必填，需要使用的JS接口列表，所有JS接口列表見附錄2 }); } wx.ready(function(){ //config信息驗證後會執行ready方法，所有接口調用都必須在config接口獲得結果之後， //config是一個客戶端的異步操作，所以如果需要在頁面加載時就調用相關接口，則須把相關//接口放在ready函數中調用來確保正確執行。對於用戶觸發時才調用的接口，則可以直接調用，不需要放在ready函數中。 //----------“分享給朋友” wx.onMenuShareAppMessage({ title: "明日醫療資訊", // 分享標題desc: shareTitle, // 分享描述link: url, // 分享鏈接imgUrl: shareImgUrl, // 分享圖標type: '', // 分享類型,music、video或link，不填默認為link dataUrl: '', // 如果type是music或video，則要提供數據鏈接，默認為空success: function () { // 用戶確認分享後執行的回調函數、 }, cancel: function () { // 用戶取消分享後執行的回調函數} }); //------------"分享到朋友圈" wx.onMenuShareTimeline({ title: '明日醫療資訊', // 分享標題link: '', // 分享鏈接imgUrl: shareImgUrl, // 分享圖標success: function () { // 用戶確認分享後執行的回調函數}, cancel: function () { // 用戶取消分享後執行的回調函數} }); //-------------分享到QQ wx.onMenuShareQQ({ title: '明日醫療資訊', // 分享標題desc: shareTitle, // 分享描述link: '', // 分享鏈接imgUrl: shareImgUrl, // 分享圖標success: function () { // 用戶確認分享後執行的回調函數}, cancel: function () { // 用戶取消分享後執行的回調函數} }); //-------------分享到QQ空間wx.onMenuShareQZone({ title: '明日醫療資訊', // 分享標題desc: shareTitle, // 分享描述link: '', // 分享鏈接imgUrl: shareImgUrl, // 分享圖標success: function () { // 用戶確認分享後執行的回調函數}, cancel: function () { // 用戶取消分享後執行的回調函數} }); });三、服務器需要的工具類和Model
① Ticket
package 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 添加到數據庫的業務根據自己需要進行實現.
③ GetRandomStr
package com.wiimedia.utils;import java.util.Random;public class GetRandomStr { /** * *<p>Project:mryl_phone_v2</p> * *<p>:mryl_phone_v2</p> * *<p>Description:生成隨即字符串</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 SignatureBean
package 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 WeixinUtil
package 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:公眾平台接口工具類</p> * *<p>Company:Wiimedia</p> * *@Athor:SongJia * *@Date:2016-7-15 上午09:37:13 * */public class WeixinUtil { /** * 發起https請求並獲取結果* * @param requestUrl 請求地址* @param requestMethod 請求方式（GET、POST） * @param outputStr 提交的數據* @return JSONObject(通過JSONObject.get(key)的方式獲取json對象的屬性值) */ public static String httpRequest(String requestUrl, String requestMethod, String outputStr) { StringBuffer buffer = new StringBuffer(); try { // 創建SSLContext對象，並使用我們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()); // 從上述SSLContext對像中得到SSLSocketFactory對象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); // 設置請求方式（GET/POST） httpUrlConn.setRequestMethod(requestMethod); if ("GET".equalsIgnoreCase(requestMethod)) httpUrlConn.connect(); // 當有數據需要提交時if (null != outputStr) { OutputStream outputStream = httpUrlConn.getOutputStream(); // 注意編碼格式，防止中文亂碼outputStream.write(outputStr.getBytes("UTF-8")); outputStream.close(); } // 將返回的輸入流轉換成字符串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(); // 釋放資源inputStream.close(); inputStream = null; httpUrlConn.disconnect(); return buffer.toString(); } catch (ConnectException ce) { ce.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } return ""; }}四、至此，分享功能已經開發完成，但是，在生成signature的時候會遇到很多問題，這裡提供一些wx.config失敗的排錯方法。
① 確認自己的生成的signature是否正確在微信提供的http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=jsapisign進行校驗
② wx.config中使用的noncestr, timestamp與用以簽名中的對應noncestr, timestamp是否一致一致…如上面（一.服務器代碼）
（有可能因為JS頁面加載順序問題，服務器生成的signature，noncestr，timestamp在wx.config中沒有獲取到）。
③ 確認url是頁面完整的url，包括GET參數部分需要去掉#後面的部分
④ config 中的appid 與用來獲取jsapi_ticket 的appid 是否一致
⑤ 報錯｛errmsg：config:ok}是debug的正常返回把調試模式關掉就OK
wx.config debug: false,
