您可以像这样添加自签名证书，然后再按…

git config --global http.sslCAInfo "C:\Program Files\Git\usr\ssl\cert.pem"

在Windows上，这对我来说很管用:

将自签名证书的内容添加到ca-bundle文件的末尾。包括-----BEGIN CERTIFICATE-----和-----END CERTIFICATE-----行

ca-bundle文件的位置通常是C:\Program Files\Git\mingw64\ssl\certs

然后，将ca-bundle文件的路径添加到全局git配置中。下面的命令可以做到这一点:git config——global http。sslCAInfo "C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt"

注意:路径依赖于ca-bundle文件的本地路径!

永久地接受特定的证书

http。sslCAPath或http.sslCAInfo。Adam Spiers的回答给出了一些很好的例子。这是这个问题最可靠的解决办法。

禁用单个git命令的TLS/SSL验证

尝试将-c与正确的配置变量传递给git，或使用Flow的答案:

git -c http.sslVerify=false clone https://example.com/path/to/git

禁用所有存储库的SSL验证

可以全局禁用ssl验证。强烈建议不要这样做，但为了完整起见，这里提到了:

git config --global http.sslVerify false # Do NOT do this!

git中有相当多的SSL配置选项。从git配置的手册页:

http.sslVerify
    Whether to verify the SSL certificate when fetching or pushing over HTTPS.
    Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

http.sslCAInfo
    File containing the certificates to verify the peer with when fetching or pushing
    over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

http.sslCAPath
    Path containing files with the CA certificates to verify the peer with when
    fetching or pushing over HTTPS.
    Can be overridden by the GIT_SSL_CAPATH environment variable.

其他一些有用的SSL配置选项:

http.sslCert
    File containing the SSL certificate when fetching or pushing over HTTPS.
    Can be overridden by the GIT_SSL_CERT environment variable.

http.sslKey
    File containing the SSL private key when fetching or pushing over HTTPS.
    Can be overridden by the GIT_SSL_KEY environment variable.

http.sslCertPasswordProtected
    Enable git's password prompt for the SSL certificate. Otherwise OpenSSL will
    prompt the user, possibly many times, if the certificate or private key is encrypted.
    Can be overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

关于http。sslCAPath选项:如果在包含证书文件的目录上执行了OpenSSL c_rehash命令，git将只检测指定目录路径下的证书文件。c_rehash命令将为每个证书创建符号链接，其中链接的名称为哈希值。例如:

$ cd /path/to/ssl/cert/directory

$ ls -al

  total 16
  drwxr-xr-x  3 user  staff    96 Oct 20 13:47 .
  drwxr-xr-x  4 user  staff   128 Oct 20 13:46 ..
  -rw-r--r--  1 user  staff  4832 Oct 20 13:47 google.pem

$ /usr/local/opt/openssl@1.1/bin/c_rehash ./

  Doing ./

$ ls -al

  total 16
  drwxr-xr-x  4 user  staff   128 Oct 20 13:58 .
  drwxr-xr-x  4 user  staff   128 Oct 20 13:46 ..
  lrwxr-xr-x  1 user  staff    10 Oct 20 13:58 f6dbf7a7.0 -> google.pem
  -rw-r--r--  1 user  staff  4832 Oct 20 13:47 google.pem

注意，c_rehash命令创建了以下符号链接:f6dbf7a7.0 -> google.pem。

您还可以用下面的命令代替c_rehash实用程序，不过请注意，下面的命令只处理*。Pem文件，而c_rehash实用程序将处理.pem， .crt， .cer或.crl文件:

for file in *.pem; do ln -s $file `openssl x509 -hash -noout -in $file`.0; done

如果您现在配置http。将sslCAPath导入到包含上述符号链接的目录，git将获取证书文件:

# contents of /etc/gitconfig
[http]
        sslCAPath = /path/to/ssl/cert/directory/

也可以配置http。sslCAPath使用一个环境变量:

export GIT_SSL_CAPATH=/path/to/ssl/cert/directory/

我经常遇到这个问题，所以写了一个脚本从服务器下载自签名证书并将其安装到~/。然后更新git-config以指向这些证书。它存储在全局配置中，因此每个远程只需要运行一次。

https://github.com/iwonbigbro/tools/blob/master/bin/git-remote-install-cert.sh

你可以将GIT_SSL_NO_VERIFY设置为true:

GIT_SSL_NO_VERIFY=true git clone https://example.com/path/to/git

或者配置Git不验证命令行上的连接:

git -c http.sslVerify=false clone https://example.com/path/to/git

请注意，如果您不验证SSL/TLS证书，那么您很容易受到MitM攻击。
