pymsteams文本换行符失效，如何实现与Python终端一致的MS Teams输出？

从Linux机器获取网络接口输出后推送至MS Teams频道，发现换行符无法正常生效，导致显示格式混乱。

代码示例 #

stdin, stdout, stderr = client.exec_command("ip addr | grep bond0")
pwd_out=stdout.read().decode("utf-8")
new_text="Link Status:"+"\n" +  pwd_out
print(new_text)
myTeamsMessage.text(new_text)

预期输出（Python终端） #

Link Status:
6: ens1f0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000
9: ens2f1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000
10: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
11: bond0.400@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    inet 192.168.40.10/24 brd 192.168.40.255 scope global noprefixroute bond0.400
12: bond0.501@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    inet 192.168.51.16/24 brd 192.168.51.255 scope global noprefixroute bond0.501

实际Teams输出 #

payload: {'text': 'Link Status:\n6: ens1f0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000\n9: ens2f1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000\n10: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000\n11: bond0.400@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000\n    inet 192.168.40.10/24 brd 192.168.40.255 scope global noprefixroute bond0.400\n12: bond0.501@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000\n    inet 192.168.51.16/24 brd 192.168.51.255 scope global noprefixroute bond0.501\n'}

MS Teams的文本消息默认解析Markdown语法，普通换行符\n无法被识别，需通过以下方式调整格式：

方法1：替换换行符为Markdown兼容格式 #

将文本中的\n替换为\n\n（Markdown换行规则）或<br>（HTML换行标签），Teams会自动解析并实现换行：

stdin, stdout, stderr = client.exec_command("ip addr | grep bond0")
pwd_out=stdout.read().decode("utf-8")
# 方案A：用Markdown换行规则
formatted_text = "Link Status:\n\n" + pwd_out.replace("\n", "\n\n")
# 方案B：用HTML换行标签
# formatted_text = "Link Status:<br>" + pwd_out.replace("\n", "<br>")
myTeamsMessage.text(formatted_text)

方法2：用Markdown代码块包裹内容 #

将输出内容放在Markdown代码块中，既能完整保留原始换行和缩进，还能赋予代码样式，可读性更强：

stdin, stdout, stderr = client.exec_command("ip addr | grep bond0")
pwd_out=stdout.read().decode("utf-8")
# 用三个反引号包裹内容，指定shell格式可选
formatted_text = "Link Status:\n```shell\n" + pwd_out + "\n```"
myTeamsMessage.text(formatted_text)

方法3：使用Teams自适应卡片（定制化展示） #

如果需要更灵活的排版，可使用自适应卡片，卡片会严格保留文本的原始格式：

from teams.models import AdaptiveCard, TextBlock

card = AdaptiveCard()
card.add(TextBlock(text="Link Status:", size="large"))
# 用pre标签强制保留原始格式
card.add(TextBlock(text=f"<pre>{pwd_out}</pre>", wrap=True))
myTeamsMessage.attachments([card])
