前几天因为项目所需要实现微信分享接口，在网上搜了一大堆，实现办法大致分为两种，第一：在body之后加一个img标签并且设置display:none,这种方法感觉不科学所以我没有测试过。第二：使用微信的分享接口，但在网上也没用找到完整的示例，还是自己折腾吧，请看下面。
实现工具：GetwxLink
第一步：
先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。
注：认证帐号才有分享权限
第二步
创建一个demo.php文件和wxshare.js
demo.php
<?php
// 步骤1.设置appid和appsecret
$appid = 'wxd75a2b20d3a54752';
$appsecret = '9b32270f32874ea7a7427f88ff770777';
// 步骤2.生成签名的随机串
function nonceStr($length){
$str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';//62个字符
$strlen = 62;
while($length > $strlen){
$str .= $str;
$strlen += 62;
}
$str = str_shuffle($str);
return substr($str,0,$length);
}
// 步骤3.获取access_token
$result = http_get('https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$appsecret);
$json = json_decode($result,true);
$access_token = $json['access_token'];
function http_get($url){
$oCurl = curl_init();
if(stripos($url,"https://")!==FALSE){
curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($oCurl, CURLOPT_SSLVERSION, 1); //CURL_SSLVERSION_TLSv1
}
curl_setopt($oCurl, CURLOPT_URL, $url);
curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1 );
$sContent = curl_exec($oCurl);
$aStatus = curl_getinfo($oCurl);
curl_close($oCurl);
if(intval($aStatus["http_code"])==200){
return $sContent;
}else{
return false;
}
}
// 步骤4.获取ticket
$url = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=$access_token";
$res = json_decode ( http_get ( $url ) );
$ticket = $res->ticket;
// 步骤5.生成wx.config需要的参数
$surl = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$ws = getWxConfig( $ticket,$surl,time(),nonceStr(16) );
function getWxConfig($jsapiTicket,$url,$timestamp,$nonceStr) {
$string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr×tamp=$timestamp&url=$url";
$signature = sha1 ( $string );
$WxConfig["appId"] = $appid;
$WxConfig["nonceStr"] = $nonceStr;
$WxConfig["timestamp"] = $timestamp;
$WxConfig["url"] = $url;
$WxConfig["signature"] = $signature;
$WxConfig["rawString"] = $string;
return $WxConfig;
}

// 步骤6.调用JS接口

wx.ready(function () {

wx.onMenuShareTimeline({

// 分享给朋友

// 分享到QQ

imgUrl: wsimg,
success: function () {

cancel: function () {

});
// 微信到腾讯微博
wx.onMenuShareWeibo({

imgUrl: wsimg,
success: function () {
alert('分享成功');
},
cancel: function () {

// 分享到QQ空间
