微信分享功能開發(fā)

用了一天時(shí)間，把微信發(fā)送給朋友和分享到朋友圈功能開發(fā)出來(lái)，在這里給大家分享一下，避免大家走彎路。

二、客戶端代碼.

   var articleId = "";
   var shareTitle="明日醫(yī)療資訊";
   var shareImgUrl="";
   var userinfo = localStorage.getItem("_userinfo");
   var timestamp;
   var noncestr;
   var signature;
   //獲取簽名

      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;

        signature=objData.signature;
         console.log(objData);
         wxShare();
      }
     });
   function wxShare(){
   wx.config({
    debug: false, // 開啟調(diào)試模式,調(diào)用的所有api的返回值會(huì)在客戶端alert出來(lái)，若要查看傳入的參數(shù)，可以在pc端打開，參數(shù)信息會(huì)通過(guò)log打出，僅在pc端時(shí)才會(huì)打印。
    appId: &#39;您的appid&#39;, // 和獲取Ticke的必須一樣------必填，公眾號(hào)的唯一標(biāo)識(shí)

   });
   }
   wx.ready(function(){
     //config信息驗(yàn)證后會(huì)執(zhí)行ready方法，所有接口調(diào)用都必須在config接口獲得結(jié)果之后，

    //----------“分享給朋友”
    wx.onMenuShareAppMessage({
     title: "明日醫(yī)療資訊", // 分享標(biāo)題
     desc: shareTitle, // 分享描述
     link: url, // 分享鏈接

   });

三、服務(wù)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(shù)據(jù)庫(kù)的業(yè)務(wù)根據(jù)自己需要進(jìn)行實(shí)現(xiàn).
③ GetRandomStr

package com.wiimedia.utils;
 
import java.util.Random;
 
public class GetRandomStr {
 /**

  * 
  *<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;

 public static String httpRequest(String requestUrl, String requestMethod, String outputStr) { 
 
  StringBuffer buffer = new StringBuffer();

?四、至此，分享功能已經(jīng)開發(fā)完成，但是，在生成signature的時(shí)候會(huì)遇到很多問(wèn)題，這里提供一些wx.config失敗的排錯(cuò)方法。

① 確認(rèn)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(jìn)行校驗(yàn)

② wx.config中使用的noncestr, timestamp與用以簽名中的對(duì)應(yīng)noncestr, timestamp是否一致一致…如上面（一.服務(wù)器代碼）?
（有可能因?yàn)镴S頁(yè)面加載順序問(wèn)題，服務(wù)器生成的signature，noncestr，timestamp在wx.config中沒有獲取到）。

③ 確認(rèn)url是頁(yè)面完整的url，包括GET參數(shù)部分?
需要去掉#后面的部分

④ config 中的 appid 與用來(lái)獲取 jsapi_ticket 的 appid 是否一致

⑤ 報(bào)錯(cuò)｛errmsg：config:ok}是debug的正常返回把調(diào)試模式關(guān)掉就OK?
wx.config debug: false,?

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持PHP中文網(wǎng)。
