新起点博客想要实现H5纯静态页面分享到微信朋友圈带图片显示需要前提条件
1、微信公众号已成功认证
2、微信公众号中添加js安全域名
3、添加ip白名单（服务器外网ip）
HTML代码部分：
<?php
// 步骤1.设置appid和appsecret
$appid = 'wxbb446b55816eb32b'; //此处填写绑定的微信公众号的appid
$appsecret = '9288201823b0beda333a9698f861d0a8'; //此处填写绑定的微信公众号的密钥id
// 步骤2.生成签名的随机串
function nonceStr($length){
$str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJK1NGJBQRSTUVWXYZ';//随即串，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;
}
