json - 在 JSON 对象中发送数组时出错

Question

为了用 Iris Go 发送这个 JSON

{
  "response_type": "in_channel",
  "text": "It's 80 degrees right now.",
  "attachments": [
    {
        "text":"Partly cloudy today and tomorrow"
    }
  ]
}

我正在尝试这个但是没有用

ctx.JSON(iris.Map{
    "text": "It's 80 degrees right now.",
    "response_type": "in_channel",
    "attachments":[{ "text": "Partly cloudy today and tomorrow" }],
})

因为附件行出现如下错误

syntax error: unexpected {, expecting expression

你知道怎么解决吗？

Answer 1

在您的 Go 代码中，您没有为数组或其元素指定类型。假设您希望它是 iris.Map:

ctx.JSON(iris.Map{
    "text": "It's 80 degrees right now.",
    "response_type": "in_channel",
    "attachments": []iris.Map{iris.Map{ "text": "Partly cloudy today and tomorrow" }},
})
