Question

我正在努力理解如何从一个uri呼叫中获得响应以传递给另一个。我正在为我的存储系统创建一个剧本。对于在自定义标头中传递的所有REST调用，它需要一个SessionKey＆＃34; X-HP3PAR-WSAPI-SessionKey＆＃34;

初始身份验证REST调用成功，我看到了SessionKey。我无法将SessionKey传递给后续调用。

有什么建议吗？

Ansible版本2.0.0.2

Answer 1

您正在混合uri模块中的标头的新旧语法。

当您使用过时的Ansible 2.0版本时，headers参数将被完全忽略。

升级到当前的Ansible版本。

供参考：

如果您使用Ansible＆lt; 2.1使用HEADER_*，
如果您使用Ansible＆gt; = 2.1定义headers下的所有标题。

Answer 2

在修复标题并将Ansible更新到最新版本后发布更正的功能代码以供参考。
