HomeBackend DevelopmentPHP Tutorial微信开发不能返回数据的奇怪问题

先上代码:

                //获取td栏的代码            	$regex = "/<td  Height=\"30\">([\s\S]*?)<\/td>/";                $str = file_get_contents('http://www.zh818.com/get/quanguo-jg/');                $matches = array();                preg_match_all($regex, $str, $matches);                echo "\n";                            	//获得网址                  $href ='/<a .*?href="(.*?)".*?>/is';                $href_single = array();                 if(preg_match($href, $matches[0][1], $href_single))                               //根据获得的网址获取表格信息                     $regex = '/<table border="1" width="100%">.*([\d\.]+?).*<\/table>/sU';                $str = file_get_contents($href_single[1]);                $matches = array();                   if(preg_match($regex, $str, $matches))                $result = $this->transmitText($object, $matches);

[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?[/size]


回复讨论(解决方案)

查询了一下,好象是新浪sae的问题,但是不知道该怎么解决

SAE 不能使用 file_get_contents 函数

SAE 不能使用 file_get_contents 函数
嗯,最后用$f = new SaeFetchurl();   $str = $f->fetch($href_single[1]);搞定了,不过file_get_contents直接传入网址的字符串是可以使用的

Are there any alternatives to PHP sessions?Are there any alternatives to PHP sessions?Apr 29, 2025 am 12:36 AM

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
