我正在尝试使用带有 SSH 库的 Robot Framework 中的私钥与托管在 AWS 云上的机器创建 SSH 连接。使用的关键字是 - Login With Public Key。下面是当前用红色编辑器在 Eclipse 中编写的代码
*** Variables ***
${hostname} <hostname>
${username} <username>
*** Test Cases ***
ConnectionToJump
Set Log Level DEBUG
Enable Ssh Logging logfile.txt
Log Starting the connection to jump server
${connectionIndex} Open Connection ${hostname} port=22
${output} Login With Public Key ${username} C:/Users/<username>/.ssh/id_rsa.ppk
Log ${output}
但不幸的是,这在 Eclipse 控制台中给我带来了错误,看起来像

从logfile.txt查看SSH日志,信息如下

我能够使用相同的密钥文件成功地使用 PuTTY 和 MobaXterm 手动创建连接。
你能帮我理解我在做什么错误或者需要改变什么来建立成功的连接。
谢谢
