Question

我正在尝试将this wenderlich tutorial改为Swift 3语法，以创建一个带有在Heroku上托管的rails后端的iOS前端。

让我知道是否有任何其他代码可以分享，但它似乎是一个auth问题。这是为请求设置授权标头的位置：

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")

我无法告诉如何调试这些请求。如果我单步执行调试器中的代码，请求对象看起来非常平坦，如果我打印请求，我只看到URL。

对heroku服务器的请求（也是从该教程构建的）返回401，它似乎没有进入任何rails方法。它只返回一个未经授权的401：

嵌套的“api”键是否具有相同的参数似乎很奇怪？我不清楚调试这些请求的方向。我不能使用像Charles这样的服务，因为它们是https吗？

Answer 1

感觉像个傻瓜......

base64EncodedString是可选的。

修复：

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

我能够通过此URLRequest方法获取有关请求的更多详细信息：

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

iOS HTTPS请求到Rails Heroku调试401错误
