我正在尝试使用Slack 的 chat.postMessage API 调用发送消息。我在 HTTP GET 中编码我的测试消息没有问题，但我试图在 HTTP POST 请求中使用 JSON 实现相同的结果。

我一直在测试Postmancurl和两者，但 Slack 似乎根本不承认我的请求正文。

{
  "ok": false,
  "error": "not_authed"
}

在curl中，我的请求编码如下：

curl -H "Content-type: application/json" -X POST -d '{"token":"my-token-here","channel":"#channel-name-or-id","text":"Text here.","username":"otherusername"}'

在 Postman 中，这是原始的身体：

{
    "token":"my-token-here",
    "channel":"#channel-name-or-id",
    "text":"Text here.",
    "username":"otherusername"
}

我以前没有做过这样的事情，所以我不确定我是否遗漏了什么。谢谢！

我有点晚了，但我希望这可以帮助像我这样偶然发现这个问题的其他人。我刚刚与 Slack 取得联系，他们是这样告诉我的：

Slack Web API 根本不接受 JSON 数据——所以除了更改 Content-Type 之外，这些变量应该使用标准的 HTTP 表单属性发布。

我们计划在未来支持 JSON 数据以保持未来的一致性。

因此，您的 cURL 行应如下所示：

curl -X POST -d 'token=my-token-here&channel=#channel-name-or-id&text=Text here.&username=otherusername'`

我希望这有帮助！:)

Okay, after re-reading the documentation I found it:

JSON-encoded bodies

For these write methods, you may alternatively send your HTTP POST data as Content-type: application/json.

There are some ground rules:

  • You must explicitly set the Content-type HTTP header to application/json. We won't interpret your POST body as such without it.
  • You must transmit your token as a bearer token in the Authorization HTTP header.
  • You cannot send your token as part of the query string or as an attribute in your posted JSON.
  • Do not mix arguments between query string, URL-encoded POST body, and JSON attributes. Choose one approach per request.
  • Providing an explicitly null value for an attribute will result in whichever default behavior is assigned to it.

And the curl example. Notice the Authorization header.

curl -X POST \
     -H 'Authorization: Bearer xoxb-1234-56789abcdefghijklmnop' \
     -H 'Content-type: application/json; charset=utf-8' \
    --data '{"channel":"C061EG9SL","text":""..."}' \

这可能不符合完整的答案，但如果目的是发送消息附件，您可以发送一个urlencoded JSON 结构作为attachments参数的值，如下所示（为了清楚起见分成多行）：

https://slack.com/api/chat.postMessage?
token=YOUR-TOKE-N000&
channel=%23alerts&
text=Hi&
attachments=%5B%7B%22color%22%3A%22good%22%2C%22fallback%22%3A%22plain+text%22%2C%22text%22%3A%22colored+text%22%7D%5D

的值attachments是 URL 编码的[{"color":"good","fallback":"plain text","text":"colored text"}]。您应该能够使用此处描述的所有附件属性。

截至2018 年 3 月，Slack现在支持带有JSON正文的POST

端点：https://slack.com/api/chat.postMessage

标题：Authorization: Bearer xoxp-your-hardly-find-token-here

身体：{"channel":"CH9NN37","text":"something from me!"}

注意 Authorization标头中的Bearer 。

Slack 已更新，现在可以使用。试试这个例子：

curl -X POST -H 'Content-type: application/json' --data '{"text":"This is a line of text.\nAnd this is another one."}' https://hooks.slack.com/services/AAAAAA/BBBBBB/CCCCCC

有关文档，请参阅https://api.slack.com/incoming-webhooks。

尝试将每个属性放在自己的 -d 参数中，如下所示：

curl https://slack.com/api/chat.postMessage -X POST -d "channel=#tehchannel" -d "text=teh text" -d "username=teh user" -d "token=teh-token-you-got-from-teh-page-that-machinehead115-linked-to" -d "icon_emoji=:simple_smile:"

在邮递员上，您可以像这样构建您的请求：

网址（POST）：https ://slack.com/api/chat.postMessage

然后在Headers部分下放置这两个标题：

  1. 键（Content-Type）值（application/json）

  2. 键（Authorization）值（YOUR-TOKEN-NAME）

然后在表格Body部分中输入raw您的数据：

    {"channel": "CHANNEL-NAME", "data": "You better post this to channel"}

not_authed表示未提供身份验证令牌。

您在请求中传递了哪个令牌？您需要传递您的 OAuth 令牌，您可以从此处获取。

我在powershell中做了这个，它就像一个魅力。

$url="https://slack.com/api/chat.postMessage"
    $messageContent= # your message here
    $token = # your token here
    $channel = # channel name
    $opt_username= # optional user name

    $body = @{token=$token;channel=$channel;username=$opt_username;text=$messageContent;pretty=1}

    try
    {
        Invoke-WebRequest -Uri $url -Method POST -Body $body
    }
    catch
    {
        Write-Host "StatusCode:" $_.Exception.Response.StatusCode.value__ 
        Write-Host "StatusDescription:" $_.Exception.Response.StatusDescription        
    }

如果你使用 java 和 spring 这样的依赖，瞧！干得好

     * Make a POST call to the chat.PostMessage.
     */
    public void chatPostMessage(Message message)

        RestTemplate restTemplate = new RestTemplate();

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

下面的 curl 命令对我有用。

curl -X POST -H 'Authorization: Bearer xoxb-41234078565-14457098702432-ZLJj9UFOZKnOJtjNW4dv3ukG'  -H 'Content-type: application/json; charset=utf-8'  --data '{"channel":"#general","text":"I hope the tour went well, Mr. Wonka."}' https://slack.com/api/chat.postMessage
