微信开发不能返回数据的奇怪问题
本帖最后由 programmer_wei 于 2014-03-16 00:46:52 编辑

先上代码：
  1. <br>                //获取td栏的代码<br>            
  2. $regex = "/([\s\S]*?)<\/td>/";<br>                $str = file_get_contents('http://www.zh818.com/get/quanguo-jg/');<br>                $matches = array();<br>                preg_match_all($regex, $str, $matches);<br>                echo "\n";<br>                <br>            
  3. //获得网址  <br>                $href ='//is';<br>                $href_single = array(); <br>                if(preg_match($href, $matches[0][1], $href_single))<br>               <br>                //根据获得的网址获取表格信息     <br>                $regex = '/.*([\d\.]+?).*<\/table>/sU';<br>                $str = file_get_contents($href_single[1]);<br>                $matches = array();   <br>                if(preg_match($regex, $str, $matches))<br>                $result = $this->transmitText($object, $matches);<br><br><span style="font-size: 14px;">[size=13px]我要实现的功能是微信手机端用户发送请求，服务器通过在一个网站上的html代码中使用正则表达式获取指定信息，然后通过微信接口返回给用户，但是现在当微信端用户发出请求后并不能收到返回的信息，本来以为是不是因为服务器连接到相应网站抽取信息超时引起的，但是当我把代码倒数第四行的$href_single[1]直接改为http网址时，经过测试微信手机端又可以接收到返回信息了，但是$href_single[1]里面的内容实际上就是一个http网址啊，他们格式都是一样的，这到底是怎么回事呢？</span>[/size]<br><br><font color="#FF8000">------解决方案--------------------</font><br>SAE 不能使用 file_get_contents 函数                    <div class="">
