Discord Webhooks 内容换行

Question

我刚刚创建了这个简单的 swift 函数，它可以将用户反馈发送到不和谐的 webhook，但有一个问题。该函数大部分情况下都有效，除非消息字符串中存在换行符，导致消息无法发送。有人可以帮我吗？

这是 swift 函数：

import SwiftUI

func sendFeedback(_ msg: String) {
if let url = URL(string: "full_weebhook_url") {
    let json = """
{
 "username": "\(Date.now.formatted(date: .long, time: .complete))",
 "content": "\(msg)",
 "embeds": [{
 "fields": [
  {
    "name": "Device Name",
    "value": "\(UIDevice.current.name)"
  },
  {
    "name": "Device Model",
    "value": "\(UIDevice.current.model)"
  },
  {
    "name": "Device Operating System",
    "value": "\(UIDevice.current.systemName)"
  },
  {
    "name": "Device Operating System Version",
    "value": "\(UIDevice.current.systemVersion)"
  }
  ]
  }]
}
"""
    print(json)
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.addValue("application/json", forHTTPHeaderField: "content-type")
    request.httpBody = json.data(using: .utf8)
    let task = URLSession.shared.dataTask(with: request)
    task.resume()
}
}

新行本身不是有效的 JSON 数据。你可以 如果转义新行，请在 JSON 字符串中使用新行。

例如：

 msg.replacingOccurrences(of: "\n", with: "\\n")

无论是在通话中

sendFeedback(msg.replacingOccurrences(of: "\n", with: "\\n"))

或者在你的

"content": "\(msg.replacingOccurrences(of: "\n", with: "\\n"))"
