在亚马逊Linux (CentOS / Red Hat等)上，我做了以下工作来解决这个问题。首先复制cacert。Pem从http://curl.haxx.se/ca/cacert.pem下载，放在/etc/pki/ca-trust/source/anchors/目录下。执行update-ca-trust命令。

下面是来自https://serverfault.com/questions/394815/how-to-update-curl-ca-bundle-on-redhat的一句话

Curl https://curl.se/ca/cacert.pem -o /etc/pki/ca-trust/source/anchors/curl-cacert-updated。Pem && update-ca-trust

然而，由于curl被破坏，我实际上使用这个命令来下载cacert。pem文件。

Wget——no-check-certificate http://curl.haxx.se/ca/cacert.pem

执行update-ca-trust命令后，可以重新启动web服务器服务httpd restart (apache)或service nginx restart (nginx)。

我得到的错误如下:

failed loading cafile stream: `C:\xamppPhp\apache\bin\curl-ca-bundle.crt`

我用的是windows电脑。所以我遵循以下步骤。

1. I have downloaded .pem file from " https://curl.haxx.se/docs/caextract.html "

2. Then I kept the downloaded file inside  "C:/xamppPhp/apache/bin/" folder and renamed the same downloaded file to "curl-ca-bundle.crt".

3. I restarted XAMPP and cleared the cache.
4. It's done.

希望它能帮助到一些人

谢谢@Mladen Janjetovic，

你的建议在安装了放大器的mac上对我有用。

复制:http://curl.haxx.se/ca/cacert.pem

: /应用程序/ ampp /额外的/ etc / openssl /组/ cacert.pem

用这个路径更新php.ini并重新启动Apache:

[curl]
; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo="/Applications/AMPPS/extra/etc/openssl/certs/cacert.pem"
openssl.cafile="/Applications/AMPPS/extra/etc/openssl/certs/cacert.pem"

并在windows AMPPS安装中应用了相同的设置，效果也很好。

[curl]
; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo="C:/Ampps/php/extras/ssl/cacert.pem"
openssl.cafile="C:/Ampps/php/extras/ssl/cacert.pem"

： wamp也是一样。

[curl]
; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo="C:/wamp/bin/php/php5.6.16/extras/ssl/cacert.pem"
openssl.cafile="C:/wamp/bin/php/php5.6.16/extras/ssl/cacert.pem"

如果您正在寻找使用SAN为localhost生成新的SSL证书，那么本文中的步骤在Centos 7 / Vagrant / Chrome浏览器上对我有效。

终于让这个工作了!

Download the certificate bundle. Put it somewhere. In my case, that was c:\wamp\ directory (if you are using Wamp 64 bit then it's c:\wamp64\). Enable mod_ssl in Apache and php_openssl.dll in php.ini (uncomment them by removing ; at the beginning). But be careful, my problem was that I had two php.ini files and I need to do this in both of them. One is the one you get from your WAMP taskbar icon, and another one is, in my case, in C:\wamp\bin\php\php5.5.12\ Add these lines to your cert in both php.ini files: curl.cainfo="C:/wamp/cacert.pem" openssl.cafile="C:/wamp/cacert.pem" Restart Wamp services.

如果你不能访问php.ini，添加这段代码(在$ch = curl_init();行)适合我:

$certificate_location = "C:\Program Files (x86)\EasyPHP-Devserver-16.1\ca-bundle.crt"; // modify this line accordingly (may need to be absolute)
curl_setopt($ch, CURLOPT_CAINFO, $certificate_location);
curl_setopt($ch, CURLOPT_CAPATH, $certificate_location);

然后，您只需要下载ca-bundle。CRT并保存到您在$certificate_location中指定的位置。

编者注:禁用SSL验证存在安全隐患。如果不验证SSL/HTTPS连接的真实性，恶意攻击者可以模拟可信端点(如GitHub或其他远程Git主机)，您将容易受到中间人攻击。 在使用此解决方案之前，请确保您完全理解安全问题。

我试过了，很管用

open

vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php

改变这个

 $conf[CURLOPT_SSL_VERIFYHOST] = 2;
 $conf[CURLOPT_SSL_VERIFYPEER] = true;

这个

$conf[CURLOPT_SSL_VERIFYHOST] = 0;
$conf[CURLOPT_SSL_VERIFYPEER] = FALSE;
