Slack 400错误：“the response is:missing_text_or_fallback_or_attachments”

Question

这是我的代码片段，其中我将有效负载发送到一个松弛的webhook：

dictoftitle = {i: posts_to_print[i] for i in range(0, len(posts_to_print))}

response = requests.post(web_hook_url, data=json.dumps(dictoftitle))

if response.status_code != 200:
raise ValueError('Request to slack returned an error %s, the response is:\n%s '% 
(response.status_code, response.text) )

以下是有效负载的外观：

print(dictoftitle)
{0: 'When girls are the shero of the story', 1: 'Simplified global game management: Introducing Game Servers', 2: 'Google Cloud named a leader in the Forrester Wave for Public Cloud Development and Infrastructure Platforms', 3: "Modernizing Twitter's ad engagement analytics platform", 4: 'Protect users in your apps with

我在发送有效负载时遇到错误：

    raise ValueError('Request to slack returned an error %s, the response is:\n%s '% (response.status_code, response.text) )

你知道是什么导致了这个问题吗？

您正在尝试将通用的Slack传入webhook与发送自定义有效负载的服务一起使用，对吗？您需要将它们的有效负载转换为松弛传入webhooks (https://api.slack.com/messaging/composing)所接受的格式。我希望这是有意义的。如果您对此有任何进一步的问题，请让我们知道。
