today I am trying to make a curl call to somesite which is listening to port 8080. However, calls like this get sent to port 80 and not 8080 instead:
今天我正在尝试对正在侦听端口8080的某个站点进行卷曲调用。但是,这样的调用会被发送到端口80而不是8080:
$ch = curl_init();
curl_setopt($ch, CURLOPT_PORT, 8080);
curl_setopt($ch, CURLOPT_URL, 'http://somesite.tld:8080');
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$target_response = curl_exec($ch);
curl_close($ch);
am i missing something here?
我在这里错过了什么吗?

Just a note, I've had this issue before because the web host I was using was blocking outbound ports aside from the standard 80 and 443 (HTTPS). So you might want to ask them or do general tests. In fact, some hosts often even block outbound on port 80 for security.
请注意,之前我遇到过这个问题,因为我使用的网络主机阻止了标准80和443(HTTPS)之外的出站端口。所以你可能想问他们或做一般测试。实际上,为了安全起见,一些主机甚至经常在端口80上阻止出站。

Have you tried to SSH into the server that runs this and verify the iptables rules, and/or attempt to connect via telnet to the target server?
您是否尝试通过SSH连接到运行此命令的服务器并验证iptables规则,和/或尝试通过telnet连接到目标服务器?

First check that you're able to connect using something other than PHP's horrible Curl syntax:
首先检查您是否能够使用PHP的可怕Curl语法之外的其他东西进行连接:
- Chrome's Postman is easy to use if you're on your local machine,
如果你在本地机器上,Chrome的Postman很容易使用
else look at using (for linux users)
否则看看使用(对于linux用户)
- curl somesite:8080
- wget -qO- somesite:8080
wget -qO- somesite:8080
Once you've established you can connect, then you can go about the horrible business of using PHP Curl. There are wrappers, but they're flaky that I've found.
一旦你建立起来就可以连接,那么你就可以开始使用PHP Curl了。有包装,但它们是我发现的片状。
Both Curl, Wget or similar can be very easily configured to use GET and POST methods. It's not advisible, but for more than one complicated operation using Curl I've simply given up trying to configure PHP's library correctly and simply dropped to the command line.
Curl,Wget或类似的都可以非常容易地配置为使用GET和POST方法。这是不可取的,但对于使用Curl的多个复杂操作,我只是放弃了尝试正确配置PHP库并简单地删除到命令行。
THERE ARE SECURITY IMPLICATIONS. You need to take great care to ensure that anything you give it, particularly if it's from a form or an external source, is appropriately escaped.
有安全隐患。您需要非常小心,确保您提供的任何内容,特别是来自表单或外部源的内容都适当地转义。
