}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;

//获取签名

}

//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({

三、服务器需要的工具类和Model
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) {

}
}② 添加到数据库的业务根据自己需要进行实现.
③ GetRandomStr

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;
}

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,
