Question

我有一个相对简单的指令失败了。以下安装服务。我想断言结果文本。正确的文本存在，但断言失败。那怎么可能？

这是带有断言的代码：

- name: Install the tomcat service on the remote machine 
  win_command: "{{ tomcat_install_folder }}{{ tomcat_service_installer }}"
  register: cmd_result_tomcat_service_install
- assert:
    that:
      - "'has been installed' in cmd_result_tomcat_service_install.stdout_lines"

此处包含已断言的Text'的结果已在stdout_lines中安装。

    "cmd_result_tomcat_service_install": {

        "stdout": "\r\nC:\\Users\\service_ansible>SET JAVA_HOME=D:\\Products\\CPeRef\\java\\jdk1.8.0_51 \r\n\r\nC:\\Users\\service_ansible>cd /d D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\\bin \r\n\r\nD:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\\bin>service.bat install CPeRef2 \r\nInstalling the service 'CPeRef2' ...\r\nUsing CATALINA_HOME:    \"D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\"\r\nUsing CATALINA_BASE:    \"D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\"\r\nUsing JAVA_HOME:        \"D:\\Products\\CPeRef\\java\\jdk1.8.0_51\"\r\nUsing JRE_HOME:         \"D:\\Products\\CPeRef\\java\\jdk1.8.0_51\\jre\"\r\nUsing JVM:              \"D:\\Products\\CPeRef\\java\\jdk1.8.0_51\\jre\\bin\\server\\jvm.dll\"\r\nThe service 'CPeRef2' has been installed.\r\n",
        "stdout_lines": [
            "",
            "C:\\Users\\service_ansible>SET JAVA_HOME=D:\\Products\\CPeRef\\java\\jdk1.8.0_51 ",
            "",
            "C:\\Users\\service_ansible>cd /d D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\\bin ",
            "",
            "D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\\bin>service.bat install CPeRef2 ",
            "Installing the service 'CPeRef2' ...",
            "Using CATALINA_HOME:    \"D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\"",
            "Using CATALINA_BASE:    \"D:\\Products\\CPeRef\\tomcat\\apache-tomcat-8.0.26\"",
            "Using JAVA_HOME:        \"D:\\Products\\CPeRef\\java\\jdk1.8.0_51\"",
            "Using JRE_HOME:         \"D:\\Products\\CPeRef\\java\\jdk1.8.0_51\\jre\"",
            "Using JVM:              \"D:\\Products\\CPeRef\\java\\jdk1.8.0_51\\jre\\bin\\server\\jvm.dll\"",
            "The service 'CPeRef2' has been installed."
        ]
    }
}

这里出现错误信息：

TASK [tomcat : assert] 
fatal: [v-sax-769-e-a.develop.ebiz.grp]: FAILED! => {
    "assertion": "'has been installed' in cmd_result_tomcat_service_install.stdout_lines",
    "changed": false,
    "evaluated_to": false,
    "failed": true

我想知道问题可能是结果实际上是一个数组吗？

Answer 1

这个条件

'has been installed' in cmd_result_tomcat_service_install.stdout_lines

如果字符串列表中有完全文字字符串has been installed，则

为真（在这种情况下为stdout_lines）。

但是这个

'has been installed' in cmd_result_tomcat_service_install.stdout

当字符串has been installed是一个长字符串的子字符串（在这种情况下为stdout）时，

为true。

如果要独立分析行，可以使用：

cmd_result_tomcat_service_install.stdout_lines | select('search','has been installed') | list | count > 0

数组中无法进行Ansible断言？
