java开发微信分享到朋友圈功能

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

   }    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1      jsApiList: [      '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link       dataUrl: '', // 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QQ      wx.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 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;   }        }

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 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。

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,

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持PHP中文网。
