你可以试试这个:

$client = new Client(env('API_HOST'));
$client->setSslVerification(false);

测试在guzzle/guzzle 3.*

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;

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。

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

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.

我有非常简单的解决这个问题。您可以在没有任何证书文件的情况下完成此操作。

注意，此解决方案适用于本地系统，而不适用于客户端服务器和生产服务器。

继续Laravel根文件夹-> vendor -> guzzlehttp -> guzzle -> src

打开Client.php

查找$defaults数组。看起来像这样。

$defaults = [
    'allow_redirects' => RedirectMiddleware::$defaultSettings,
    'http_errors'     => true,
    'decode_content'  => true,
    'verify'          => true,
    'cookies'         => false
];

现在主要工作是更改验证键的值..

'verify'          => false,

所以在这之后，它将不会检查SSL证书为CURL请求…这个解决方案对我来说就是工作。经过多次研究，我找到了这个解决方案…
