Enable server certificate validation on this SSL/TLS connection.

启用SSL/TLS连接上的服务器证书验证是非常关键的安全措施。当客户端（如Web浏览器、API客户端等）试图与服务器建立安全通信时，它会检查服务器提供的SSL/TLS证书，以确认其身份并确保数据传输过程中的加密是有效的。如果验证通过，表明连接到的是预期的服务器，反之则可能是中间人攻击或者证书伪造。

在很多编程语言和框架中，这通常是通过设置适当的SSL/TLS选项来完成的，比如在Python的`ssl.create_default_context()`中设置`check_hostname=True`和`verify_mode=ssl.CERT_REQUIRED`，或者在Java的`SSLSocketFactory`中配置信任管理器。

以下是一个简单的示例（Python）：

import ssl

context = ssl.create_default_context()
context.check_hostname = True
context.verify_mode = ssl.CERT_REQUIRED

# 使用context创建HTTPS连接
https_connection = ssl.wrap_socket(socket, context=context)

unable to access 'https://github.com/Cancerhjh/tmall_springboot.git/': SSL certificate problem: unable to get local issuer certificate

This error message indicates that there is an issue with the SSL certificate for the GitHub repository you are trying to access. The SSL certificate is used to establish a secure connection between your computer and the GitHub server.

There are a few possible reasons why you might be encountering this error:

1. The SSL certificate may be expired or invalid.
2. Your computer's clock may be set incorrectly, causing the SSL certificate to appear as expired.
3. Your computer may not have the necessary root certificates installed to validate the GitHub SSL certificate.

To resolve this issue, you can try the following steps:

1. Ensure that your computer's clock is set correctly.
2. Install the latest updates for your operating system and web browser.
3. Try accessing the GitHub repository using a different web browser.
4. Install the latest version of Git on your computer.
5. Add the following line to your Git configuration file:

[http]
sslVerify = false

Note: This option disables SSL certificate validation, which can be a security risk.

If none of these steps resolve the issue, you may need to contact GitHub support for further assistance.
