通过调试打印可解析的子变量

Question

我正在尝试通过Debug语句打印子变量。。

• 调试：var=junction_detail_ret_obj——工作在此处输入图像描述在此处输入图像描述

  "消息"：{"active_worker_threads"："0"，"authz_rules"："否"，"basic_auth_mode"："忽略"，"boolean_rule_header"："否"，"client_ip_http"："插入"，"cookie_include_path"："否"，"delegation_support"："否"，"forms_based_sso"："已禁用"，"fsso_config_file"："已禁用"，"http_header_ident"："，"insert_session_cokies"："是"，"junction_cookie_javascript_block"："inhead"，"junction_hard_limit"："0-使用全局值"，"junction_point"："/mga"，"junction_soft_limit"："0-使用全局值"，"junction_type"："SSL"，"mutual_auth"："否"，"preserve_kokie"："否"，"remote_http_header"："，"request_encoding"："，"scripting_support"："是"，"服务器"：[{"case_sensitive_url"："否"，"current_requests"："0"，"http_port"："，"local_ip"："，"operation_state"："联机"，"query_content_url"："，"query_contents"："未知"，"server_dn"："，"server_hostname"："，"server_port"："，"server_state"："正在运行"，"server_uuid"："，"total_requests"："802"，"虚拟连接主机名"："localhost"，"windows_style_url"："否"}]，"session_cookie_backend_portal"："是"，"stateful_junction"："否"，"tfim_sso"："否"，"transparent_path_junction"："否"}}

我想打印"operation_state:Online">

- debug: msg='{{ junction_detail_ret_obj.data.servers.["operation_state"] }}'

这不起作用正在获取以下错误。

失败！=>｛"msg"："模板化字符串时模板错误：需要名称或编号。字符串：｛｛junction_detail_ret_obj.data.servers.[\"operation_state\"]｝｝"｝要重试，请使用：--limit@/home/pa8090/ipa_firstnet/report_junction_mga.retry

下面是一个工作剧本。试试
