到目前为止一切顺利.但是当我尝试使用下面的代码在 php 中实现时，我得到URL 不存在"！我究竟做错了什么?任何帮助表示赞赏.

So far so good. But when i try to implement in php using the code below i get "URL not exists" ! What am i doing wrong? Any help appreciated.

  $url1 = "https://www.gearbest.com/mobile-phones/pp_1686789.html?wid=1817324";
  $curl1 = curl_init($url1);
  curl_setopt($curl1, CURLOPT_NOBODY, true);
  curl_setopt($curl1, CURLOPT_CONNECTTIMEOUT, 0);
  curl_setopt($curl1, CURLOPT_TIMEOUT, 5); //timeout in seconds


  $result1 = curl_exec($curl1);

  if ($result1 !== false)
  {
    $statusCode1 = curl_getinfo($curl1, CURLINFO_HTTP_CODE);
    if ($statusCode1 == 404)
    {
      echo "URL Not Exists";
    }
    else
    {
       echo "URL Exists";
    }
  }
  else
  {
    echo "URL not Exists";
  }

推荐答案

首先，您发布的代码是有效的.你不需要改变它.

First of all, the code you posted is valid. You don't need to alter it.

如果你只是和前任一起试试.https://www.google.com 它有效.

If you just try it with ex. https://www.google.com it works.

问题在于您的 PHP 版本使用 LibreSSL 进行 php-curl HTTPS 连接.

The problem is that your version of PHP uses LibreSSL for php-curl HTTPS connections.

我在 macOS 上遇到了同样的问题，我的 PHP 版本使用了 OpenTransport.

I have the same issue on macOS where my version of PHP uses OpenTransport.

您要连接的网站需要以 LibreSSL 无法处理的方式建立 SSL 连接.

The website you're connecting to requires to establish a SSL connection in a way that LibreSSL is not able to handle.

您需要编译/安装 OpenSSL 并在已编译用于 php-curl 的 PHP 解释器上运行您的代码.

You need to compile/install OpenSSL and run your code on a PHP interpreter that has been compiled to use it for php-curl.

更新:

当您使用 macOS 时，您可以从源代码编译 PHP.谷歌搜索 macos compile php from source 将返回一个食谱"列表来做到这一点.

as you're on macOS you may compile PHP from source. Googling for macos compile php from source will return a list of "recipes" to do that.

如果您使用 brew 来编译 PHP(以及所有网络应用程序堆栈")，您可以在这里查看:

If you use brew to compile PHP (and all the "web applications stack") you may take a look here:

osx 10.10 Curl POST到 HTTPS 网址会出现 SSLRead() 错误

问题(和答案)还解决了与您问题中的问题类似的问题.

The question (and answer) also address a problem similar to the one in your question.
