使用 Axios 在 Microsoft Teams 中发布消息答案

【问题标题】：Using Axios to post a message in Microsoft Teams使用 Axios 在 Microsoft Teams 中发布消息
【发布时间】：2022-01-16 18:22:52
【问题描述】：

2020 年 16 月 10 日更新的问题 我简化了代码，因此它不再包含 if 语句来运行 postMessageToTeams 函数，并且我添加了我在 catch 中收到的错误响应。希望这能让调试变得更容易。

当我从我的 Visual Studio 终端运行脚本时它可以工作，但从我的cmder 运行它时它不起作用。所以我认为这与我的cmder设置有关。

目标

我正在通过 testcafe 运行一些自动化任务，并希望在完成特定任务时在 Microsoft Teams 中收到通知。为此，我在我的频道中创建了一个 webhook，并希望向我的 webhook URL 发送一个 POST 请求。但是，这样做时，我收到 405 错误。在 Postman 中试用时，它确实可以使用相同的 JSON 数据。

我的代码（我对 https://gist.github.com/johnsibly/806a7190fbdc4b439ed040f327e6e679 的代码稍作改动以进行此次测试）

const axios = require('axios'); // axios must be installed via npm i axios
const webhookURL = "https://outlook.office.com/webhook/xxxxx"; // this holds my webhook URL

postMessageToTeams();

async function postMessageToTeams(title, message) {
    const card = {
      "@type": "MessageCard",
      "@context": "http://schema.org/extensions",
      "themeColor": "0072C6",
      "summary": "Summary description",
      "sections": [
        {
          "activityTitle": "Testcafe",
          "text": "Testcafe is talking to you"
        }
      ]
    };

    try {
      const response = await axios.post(webhookURL, card, {
        headers: {
          'content-type': 'application/vnd.microsoft.teams.card.o365connector',
          'content-length': `${card.toString().length}`,
        },
      });
      return `${response.status} - ${response.statusText}`;
    } catch (err) {
        console.log(err)
      return err;
    }
  }

如果您需要完整的错误消息才能正确调试，请告诉我。

邮递员

POST 请求的正文（原始）

{
  "@type": "MessageCard",
  "@context": "http://schema.org/extensions",
  "themeColor": "0072C6",
  "summary": "Summary description",
  "sections": [
    {
      "activityTitle": "Testcafe",
      "text": "Testcafe is talking to you"
    }
  ]
}

回应

1，消息发布在我的团队频道中

【问题讨论】：

我在没有 if 条件的情况下直接调用了“postMessageToTeams”函数，它运行良好。您能否发布正确的回复消息。
我已经更新了原始问题。我简化了代码，使其不再包含 if 语句，并在我的 catch 部分添加了错误响应。
根据错误代码'GET'操作不支持云请使用“POST”操作。
我也看到了，但是，我正在使用 POST 操作。我做了更多的测试，这似乎在我的 Visual Studio Code 终端中有效，但是当我通过 Cmder 运行我的脚本时它不起作用。因此，我觉得这可能与我的 Cmder 代理设置有关。
它在我的visual studio中也可以，它必须是Cmder的代理设置。

【解决方案1】：

您应该让axios 处理有效载荷长度的计算，因此删除此行：

'content-length': `${card.toString().length}`

您的帖子生成的脚本如下所示：

const axios = require('axios'); // axios must be installed via npm i axios
const webhookURL = "https://outlook.office.com/webhook/xxxxx"; // this holds my webhook URL

postMessageToTeams();

async function postMessageToTeams(title, message) {
    const card = {
      "@type": "MessageCard",
      "@context": "http://schema.org/extensions",
      "themeColor": "0072C6",
      "summary": "Summary description",
      "sections": [
        {
          "activityTitle": "Testcafe",
          "text": "Testcafe is talking to you"
        }
      ]
    };

    try {
      const response = await axios.post(webhookURL, card, {
        headers: {
          'content-type': 'application/vnd.microsoft.teams.card.o365connector'
        },
      });
      return `${response.status} - ${response.statusText}`;
    } catch (err) {
        console.log(err)
      return err;
    }
  }

发现这对我有用。
