微信对外提供了API接口，让我们可以通过授权的方式获取到自己公众号里面的文章，或者你也可以通过爬虫去抓取微信的文章，但是微信的图片默认是不允许外部调用的
这里我找到了两种方案
第一种
在JS中提前把图片加载到本地，然后从本地缓存中读取图片
var showImg = function (url) { var frameid = "frameimg" + Math.random(); window.img = "<img id="img" src="" + url + "?" + Math.random() + "" /><script>window.onload = function() { parent.document.getElementById("" + frameid + "").height = document.getElementById("img").height+"px"; }<" + "/script>"; return "<iframe id="" + frameid + "" src="javascript:parent.img;" frameBorder="0" scrolling="no" width="100%"></iframe>";}第二种
用PHP模拟浏览器请求
$url = $request->input("url");$ch = curl_init();$httpheader = array( "Host" => "mmbiz.qpic.cn", "Connection" => "keep-alive", "Pragma" => "no-cache", "Cache-Control" => "no-cache", "Accept" => "textml,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8", "User-Agent" => "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/537.36", "Accept-Encoding" => "gzip, deflate, sdch", "Accept-Language" => "zh-CN,zh;q=0.8,en;q=0.6,zh-TW;q=0.4");$options = array( CURLOPT_HTTPHEADER => $httpheader, CURLOPT_URL => $url, CURLOPT_TIMEOUT => 5, CURLOPT_FOLLOWLOCATION => 1, CURLOPT_RETURNTRANSFER => true);curl_setopt_array( $ch , $options );$result = curl_exec( $ch );curl_close($ch);header("Content-type: image/jpg");echo $result;exit;两种方法类似，我目前用的JS的方式，测试过可以用
