在使用expect和send模块时，send不能正常工作。

Question

我尝试了Shell模块的"expect“和"send”功能，代码正在运行，但它没有发送密码，它只是退出了剧本。

 ---
    - hosts: localhost
      become: yes
      vars:
      - remote_password: redhat
      tasks:
      - name: connecting to a remote host not an ansible slave
        shell: |
         set timeout 300
         spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.48.133
         expect "password: "
         send "{{ remote_password }}\n"
         interact
         exit 0
        args:
         executable: /usr/bin/expect

输出：

 "stdout_lines": [
        "spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.48.133",
        "/bin/ssh-copy-id: INFO: Source of key(s) to be installed: \"/root/.ssh/id_rsa.pub\"",
        "/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed",
        "/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys",
        "root@192.168.48.133's password: "
    ]
}

不知道为什么这不管用。为什么它不提供密码。

您应该使用\r而不是\n，并删除双引号。下面是工作代码。

     spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.48.133
     expect "password: "
     send {{ remote_password }}\r
     interact
