HomeBackend DevelopmentPHP Tutorial用php无法获取网页内容,但可以用浏览器访问网页内容,什么情况?

本帖最后由 u013067065 于 2014-01-03 13:46:46 编辑

大家根据事实推理一下是什么问题
1、服务器可以用浏览器正常访问目标网页
2、一样的网址用php无法获取网页内容。

测试代码:
<?php$a = file_get_contents('目标网址');var_dump($a);?>


结果如下:

无论怎样,始终获得一段js。这段js好像负责转向。



而且这段代码好像是动态的,每次函数名变量名都会自己动态改变,应该是某种软件自动生成的。


3、一样的程序代码,其他服务器可以正常获取到目标网址的网页内容。

根据以上事实,那么可以推断哪里出问题?

目标网站针对服务器做出的限制?还是服务器的配置问题?求 解答!

js 代码是要运行后才会出结果的
你只取得了 js 代码,但并没有运行,如何能得到结果?

这就是问题所在了。

可能第三条事实我没有描述清楚,第三条测试获取到的网页内容是正常的网页内容。并不是js。

可以确定是对方开启防采集之类的机制了。因为刚开始可以获取到,随着不断的读取,就没法获取了。
