证书_verify_fail jenkins api

Question

因此，我有一些虚拟机，我正在创建此Python脚本，该脚本连接到我们运行的Jenkins网站，一切都有效：

然后我在另一台服务器上运行了完全相同的代码，但是这次我得到了这个有线错误？

$ py test.py

似乎在抱怨一些证书错误吗？，我以前从未见过，所以我想知道我是否可以找到有关要解决的问题的建议？

这两台机器都运行Python 3.10.2，并安装了相同的软件包。

代码本身看起来像这样：

try:
    import jenkins
except ImportError:
    import pip
    pip.main(["install", "--upgrade", "python-jenkins"])
    import jenkins

# Login settings
JENKINS_URL = "https: // xxx.com"
USERNAME = "xxx"
API_TOKEN = "xxx"
JENKINS_NODES = ["PD100089"]
# Connect to server with API token
jenkins_connection = jenkins.Jenkins(JENKINS_URL, USERNAME, API_TOKEN)

# Loop through list of nodes and make them online
for node in JENKINS_NODES:
    # Get node XML configurations
    test = jenkins_connection.get_node_info(node)

    # Check if XML node configuration is online/offline
    if not test['offline']:
        print("- " + node + " is already online...")
        # Stop script
        continue

    # Turn node back online
    print("- Turning " + node + " back online...")
    jenkins_connection.enable_node(node)

我可以从Google Chrome上访问两台机器上的网站，没有任何问题。

看来您的第二台服务器在证书链中具有自签名证书。您可以尝试禁用SSL验证。

jenkins = Jenkins(url, username, password, ssl_verify=False)
