iOS HTTPS請求向Rails Heroku調試401錯誤

Question

我正在嘗試使該wenderlich教程適應Swift 3語法，以創建一個以Heroku托管的rails后端為前端的iOS。

讓我知道是否還有其他代碼可以共享，但這似乎是一個auth問題。 在此處為請求設置授權標頭：

let basicAuthString = "\(HTTPHelper.API_AUTH_NAME):\(HTTPHelper.API_AUTH_PASSWORD)"
let utf8str = basicAuthString.data(using: String.Encoding.utf8)
let base64EncodedString = utf8str?.base64EncodedString(options: Data.Base64EncodingOptions())

request.addValue("Basic \(base64EncodedString)", forHTTPHeaderField: "Authorization")

我在告訴如何調試這些請求時遇到了麻煩。 如果我在調試器中逐步執行代碼，則請求對象看起來很平坦，如果我打印請求，我只會看到URL。

對heroku服務器（也是從該教程構建的）的請求返回401，並且似乎沒有輸入任何rails方法。 它只會返回未經授權的401：

嵌套的“ api”鍵具有相同的參數似乎不奇怪嗎？ 我不清楚調試這些請求的方向。 我不能使用像Charles這樣的服務，因為它們是https，對嗎？

Answer 1

覺得自己像個傻瓜...

base64EncodedString是可選的。

固定：

request.addValue("Basic \(base64EncodedString!)", forHTTPHeaderField: "Authorization")

我可以使用以下URLRequest方法獲取有關請求的更多詳細信息：

print("request header:\(request.allHTTPHeaderFields)")
