为什么 file_get_contents 可用于 google.com 而不能用于我的网站? [英] Why does file_get_contents work with google.com but not with my site?

问题描述

$page1 = file_get_contents('http://www.google.com');

$page2 = file_get_contents('http://localhost:8000/prueba');

当我回显结果时，在 Google 上它可以工作，但在我的网站上却不起作用.当我把地址放在资源管理器上时.这发生在我在 django 中制作的所有网站上.:(

When I echo the results, with Google it works but not with my site. And when I put the address on the explorer works. And this happen with all the site that i make in django. :(

推荐答案

对于使用 PHP 内置 Web 服务器(在我的情况下使用 Laravel)遇到此问题的任何人，这是由于您的请求被 file_get_contents()/卷曲函数.

For anyone having this problem using PHP Built-in web server (with Laravel in my case), it is caused by your request being blocked by file_get_contents() / curl functions.

文档 开发服务器说

如果请求被阻止，PHP 应用程序将停止.

PHP applications will stall if a request is blocked.

由于PHP内置服务器是单线程的，在你的服务器上请求另一个url将停止第一个请求并超时.

Since the PHP built-in server is single threaded, requesting another url on your server will halt first request and it gets timed out.

作为解决方案，您可以使用适当的网络服务器(nginx、apache 等).

As a solution, you can use proper web server (nginx, apache etc.).

到目前为止，我真的建议您使用 Laravel Sail 作为 PHP 项目的开发环境.它为您设置和配置不同服务(网络服务器、数据库、队列等)节省了大量时间.

As of now, I really suggest you to use Laravel Sail as a development environment for PHP projects. It saves you lots of time with setup and configuration of different services (webserver, databases, queues, etc.).
