当在浏览器中可以访问URL时,SSH Curl不起作用

仍未解决 ):

Laravel - composer update: Connection refused

但我在另一篇文章中提到了一个更具体的问题。

$ cd /home/user/www/prod/

那么,如果我尝试:

$ curl https://larapack.io/packages.json

我得到:

curl: (7) Failed to connect to larapack.io port 443: Connection refused

但如果我这样做了:

$ curl https://packagist.org/packages.json

请注意,这两个文件都可以通过我的浏览器访问。

IPv6协议 防火墙 ,但是:

• 我找不到合适的方法来检查这两个是否都是残疾人。

这似乎不是用户代理/引用问题:

$ curl -A "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3315.4Safari/537.36" https://larapack.io/packages.json

curl: (7) Failed to connect to larapack.io port 443: Connection refused

这似乎不是IPV6问题: (选项 -4

$ curl -4 https://larapack.io/packages.json

curl: (7) Failed to connect to larapack.io port 443: Connection refused

这似乎不是ssl问题: -k 跳过ssl)

$ curl -k https://larapack.io/packages.json

curl: (7) Failed to connect to larapack.io port 443: Connection refused

这似乎不是防火墙问题: firewall=none

它不适用于 wget :

$ wget https://larapack.io/packages.json

pathconf: Value too large for defined data type

也没有 nc

$ nc larapack.io 443

我试着用php卷曲,结果成功了!所以似乎只有SSH:

<?php

$url = "https://larapack.io/packages.json";

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => $url
));
$resp = curl_exec($curl);
curl_close($curl);

echo $resp;
