Question

我有一段代码，我试图通过使用Python的paramiko库通过ssh连接到Windows机器。我第一次连接，它是成功的。但第二次，我收到错误＆＃34; SSH会话未激活＆＃34;。是因为我试图在两个不同的功能中使用它吗？代码如下所示：

class setup():#gets executed first
    @test.subsection
    def test_connection(self):
        #connecting first time
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect("8.29.9.131", username = "user", password = "pass")
        ssh.close()

class test1():#gets executed next
    @test.setup
    def setup(self): #runs first
        #connecting second time
        self.ssh = paramiko.SSHClient()
        self.ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        self.ssh.connect("8.29.9.131", username = "user", password = "pass")

    @test.maintest
    def main_test(self): #runs after setup section above
        in, out, err = self.ssh.exec_command("cmd /c C:\\\Python27\\\Scripts\\\module.py")
        print out.readlines()
        self.ssh.close()

回溯看起来像这样：

ssh会话不活跃paramiko
