Question

我正在通过API从IPAM中提取VLAN的列表，我希望能够找到未在列表中使用的未使用的“ vlanId”。我期望我可以将with_items用于JSON内容，然后将随机函数与直到循环一起使用，并且偶尔它最初会生成列表中不存在的数字。通常情况下，它只是卡住了，并且在生成的随机数已经存在时不会生成新的随机数。

剧本：

  - uri:
      url: "#"
      validate_certs: no
      headers:
        token: "{{ token }}"
      method: GET
      force_basic_auth: yes
      return_content: yes
      register: ipam

  - set_fact:
      value: "{{ 4094 | random(start=1) }}"
    until: value not in item.vlanId
    with_items: "{{ ipam.json.data }}"
    retries: 4093

  - debug: msg="{{ value }}"

相关输出：

我当前正在使用ansible 2.4.2.0

如果这是Ansible不能/不应该做的事情，那么任何指导将不胜感激。

这就是您想要的：

foreach (ReportGeneric.ExportReportSchedulerModel report in reportList)
{
    log.Debug(report.ReportName + " Export():");
    var parametersArray = new object[1];
    parametersArray[0] = report;

    log.Debug("Thread started in ExportReport() for " + report.ReportName);

    Thread exporttoexcel = new Thread(() =>
    {
        _isStarted = false;
        //invoking DLL method
        var ret = ReportInvokeFunction(moduleName: report.ReportName.Split('_')[0], className: report.ReportName, functionName: "SelectData", parameters: parametersArray);
        if (ret > 0)
        {
            log.Debug("ExportReport() successfull " + report.ReportName);
            _isStarted = true;
        }
        else
        {
            log.Error("ExportReport() failed " + report.ReportName);
            _isStarted = false;

        }
    });

    exporttoexcel.Start();
}

说明：

- debug: msg: "{{ range(1, 4095) | difference(vlanIds) | random }}" vars: vlanIds: "{{ ipam.json.data | map(attribute='vlanId') | list }}"-创建VLAN ID列表，
map(attribute=...-生成一个从1到4094的序列，
range-从上面选择所有元素。 difference列表中没有的
vlanIds-从上面选择一个随机元素。

^{对于字符串（如标题所示），将random替换为可能的字符串列表。}

找到不在列表中的字符串/整数
