问题描述
这里只是处理一个语法错误.尝试在 HTTPotion 请求的正文中发送有效负载.尝试将数据作为 json 发送，但不确定我哪里出错了.
Just dealing with a syntax error here. Trying to send the payload in the body of the HTTPotion request. Trying to send the data as json, but not really sure where I'm going wrong.
HTTPotion.post "https://hooks.slack.com/services/a00000/b0000/XXXXXXX", [body: "{'channel': '#general', 'username': 'thedanotto', 'text': 'Pokemon are scary!', 'icon_emoji': ':ghost:'}", ["Content-Type": "application/json"]]
=> ** (SyntaxError) iex:1: 之前的语法错误:'['
有什么想法吗?
推荐答案
您在标题列表之前缺少 headers:.这应该有效:
You're missing headers: before the headers list. This should work:
HTTPotion.post "https://hooks.slack.com/services/a00000/b0000/XXXXXXX", [body: "{'channel': '#general', 'username': 'thedanotto', 'text': 'Pokemon are scary!', 'icon_emoji': ':ghost:'}", headers: ["Content-Type": "application/json"]]
