Question

当我尝试在邮件中添加附件时，我或者只获取文本，或者如果我遗漏文本，我会收到“错误”：“no_text”，有没有办法发送带有chat.postMessage的附件？< / p>

这是我用来发送消息的python代码：

r = requests.post('https://slack.com/api/chat.postMessage', params=json.loads("""
    {
        "token": "xoxp-mytokenhere",
        "channel": "C4mychannelhere",
        "attachments": [
            {
                "text": "Question?",
                "fallback": "Question?",
                "callback_id": "callback_id",
                "color": "#3AA3E3",
                "attachment_type": "default",
                "actions": [
                    {
                        "name": "question",
                        "text": "Yes",
                        "style": "good",
                        "type": "button",
                        "value": "yes"
                    },
                    {
                        "name": "question",
                        "text": "Nope",
                        "style": "good",
                        "type": "button",
                        "value": "no"
                    }
                ]
            }
        ]
    }
"""))

根据评论，我采用了以下解决方案：

r = requests.post('https://slack.com/api/chat.postMessage',     params=json.loads({
        "token": "xoxp-mytokenhere",
        "channel": "C4mychannelhere",
        "attachments": json.dumps([
            {
                "text": "Question?",
                "fallback": "Question?",
                "callback_id": "callback_id",
                "color": "#3AA3E3",
                "attachment_type": "default",
                "actions": [
                    {
                        "name": "question",
                        "text": "Yes",
                        "style": "good",
                        "type": "button",
                        "value": "yes"
                    },
                    {
                        "name": "question",
                        "text": "Nope",
                        "style": "good",
                        "type": "button",
                        "value": "no"
                    }
                ]
            }
        ])
    }))

看起来您正在尝试将JSON字符串作为整套参数发送到chat.postMessage。

chat.postMessage和其他网络API方法仅支持网址编码查询或POST正文参数，因此您的token和channel以及attachments等字段将作为应用/而是x-www-form-urlencoded键/值对。

为了使事情进一步复杂化，实际的attachments参数获取一串URL编码的JSON数据。您的JSON数组需要进行URL编码并填充到该参数中。

根据您的目标，您可以跳过使用json.loads并将该JSON字符串作为attachments参数传递，requests将为您处理URL编码 - 或者您可以在使用相同属性构建的本机Python数组上使用json.dump之类的内容。

Slack chat.postMessage附件给出了no_text
