curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

根据cURL文档，您还可以将证书传递给cURL命令:

获取可以验证远程服务器的CA证书并使用适当的选项指出此CA证书进行验证时连接。对于libcurl黑客:curl_easy_setopt(curl， CURLOPT_CAPATH capath); 使用curl命令行工具:——cacert[文件]

例如:

curl --cacert mycertificate.cer -v https://www.stackoverflow.com

其他回答

特别对于Windows用户，使用curl-7.57.0-win64-mingw或类似版本。

这有点晚了，现有的答案是正确的。但我还是得费点劲才能让它在我的Windows电脑上运行，不过这个过程其实相当简单。所以，分享一步一步的过程。

这个错误基本上意味着，curl无法验证目标URI的证书。如果您信任证书的颁发者(CA)，则可以将其添加到受信任证书列表。

为此，浏览URI(例如在Chrome上)并遵循步骤

Right click on the secure padlock icon Click on certificate, it'll open a window with the certificate details Go to 'Certification Path' tab Click the ROOT certificate Click View Certificate, it'll open another certificate window Go to Details tab Click Copy to File, it'll open the export wizard Click Next Select 'Base-64 encoded X.509 (.CER)' Click Next Give a friendly name e.g. 'MyDomainX.cer' (browse to desired directory) Click Next Click Finish, it'll save the certificate file Now open this .cer file and copy the contents (including -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----) Now go to the directory where curl.exe is saved e.g. C:\SomeFolder\curl-7.57.0-win64-mingw\bin Open the curl-ca-bundle.crt file with a text editor Append the copied certificate text to the end of the file. Save

现在，您的命令应该在curl中正常执行。

它失败了，因为cURL无法验证服务器提供的证书。

有两个选项可以让它工作:

使用带-k选项的cURL，允许cURL建立不安全的连接，即cURL不验证证书。将根CA(签署服务器证书的CA)添加到/etc/ssl/certs/ca-certificates.crt

您应该使用选项2，因为它是确保您连接到安全FTP服务器的选项。

在窗户上我遇到了这个问题。Curl是由mysysgit安装的，所以下载并安装最新版本可以解决我的问题。

否则，这些是关于如何更新您的CA证书的不错的说明，您可以尝试。

关于“SSL证书问题:无法获得本地颁发者证书”错误。需要注意的是，这适用于发送CURL请求的系统，而不是接收请求的服务器。

Download the latest cacert.pem from https://curl.se/ca/cacert.pem Add the '--cacert /path/to/cacert.pem' option to the curl command to tell curl where the local Certificate Authority file is. (or) Create or add to a '.curlrc' file the line: cacert = /path/to/cacert.pem See 'man curl', the section about the '-K, --config <file>' section for information about where curl looks for this file. (or if using php) Add the following line to php.ini: (if this is shared hosting and you don't have access to php.ini then you could add this to .user.ini in public_html).

卷毛。cainfo = " - path / to / downloaded cacert pem。”

请确保将路径用双引号括起来!!

默认情况下，FastCGI进程将每300秒解析一次新文件(如果需要，您可以通过添加几个文件来改变频率https://ss88.uk/blog/fast-cgi-and-user-ini-files-the-new-htaccess/)。

这很可能是服务器上丢失的证书。

根- >中间- >服务器

服务器至少应该发送服务器和中间体。

使用openssl s_client -showcerts -starttls ftp -crlf -connect abc:21进行调试。

如果只返回一个证书(自签名或颁发)，那么您必须选择:

修复服务器信任该证书并将其添加到您的CA证书存储(不是最好的主意) 禁用信任，例如curl -k(非常糟糕的主意)

如果服务器返回多个，但不包括自签名(根)证书:

在此链的CA存储中安装CA(根)证书，例如谷歌颁发者。(只有当你信任该CA时) 服务器是否将CA作为链的一部分发送信任链中的证书禁用的信任

如果服务器返回一个根CA证书，那么它不在您的CA存储中，您的选项是:

添加(信任)它禁用的信任

我忽略了过期/撤销的证书，因为没有消息表明它。但是您可以使用openssl x509 -text检查certs

假设您正在连接到家庭版(https://www.cerberusftp.com/support/help/installing-a-certificate/) ftp服务器，我将说它是自签名的。

请发布更多细节，比如来自openssl的输出。
