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.

没有一个答案提到，可能是连接到内部vpn的角色，我以前遇到过这个问题，并要求在专用网络上

其他回答

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。

我通过在cURL脚本中添加一行代码解决了这个问题:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

警告:这使得请求绝对不安全(参见@YSU的回答)!

到目前为止，我看到这个问题在公司网络中发生，有两个原因，其中一个或两个都可能发生在你的情况中:

由于网络代理的工作方式，它们有自己的SSL证书，从而改变了curl看到的证书。许多或大多数企业网络强制您使用这些代理。在客户端电脑上运行的一些防病毒程序也类似于HTTPS代理，这样它们就可以扫描你的网络流量。您的防病毒程序可能有禁用此功能的选项(假设您的管理员允许)。

作为旁注，上面的第2条可能会让您对被扫描的本应安全的TLS通信感到不安。这就是你的公司世界。

是的，您还需要添加一个CA证书。在Node.js中添加一个代码片段以获得更清晰的视图。

var fs = require(fs)
var path = require('path')
var https = require('https')
var port = process.env.PORT || 8080;
var app = express();

https.createServer({
key: fs.readFileSync(path.join(__dirname, './path to your private key/privkey.pem')),
cert: fs.readFileSync(path.join(__dirname, './path to your certificate/cert.pem')),
ca: fs.readFileSync(path.join(__dirname, './path to your CA file/chain.pem'))}, app).listen(port)

尝试在Ubuntu中重新安装curl，并使用sudo update-ca-certificates—fresh更新我的CA证书
