带有自签名证书的 Alamofire/ServerTrustPolicy

问题描述

我想使用 Alamofire 通过带有自签名证书的 https 连接与我的服务器进行通信.我的环境在本地主机上运行.我尝试连接，但响应一直是这样的:

I want to use Alamofire to communicate with my server over a https connection with a self signed certificate. My environment runs on localhost. I've tried to connect, but the response all the time looks like this:

Success: false
Response String: nil

我已经用以下代码完成了:

I've done it with the following code:

import Foundation
import UIKit
import Alamofire

class MessageView: UITableViewController {

    let defaultManager: Alamofire.Manager = {
        let serverTrustPolicies: [String: ServerTrustPolicy] = [
            "localhost": .DisableEvaluation
        ]

        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        configuration.HTTPAdditionalHeaders = Alamofire.Manager.defaultHTTPHeaders

        return Alamofire.Manager(
            configuration: configuration,
            serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies)
        )
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        defaultManager
            .request(.GET, "https://localhost:3443/message")
            .responseJSON { _, _, result in
                print("Success: (result.isSuccess)")
                print("Response String: (result.value)")
            }
    }

}

我已经用这行 bash 创建了服务器端证书:

I've created the server side certificates with this line of bash:

openssl req -x509 -nodes -days 999 -newkey rsa:2048 -keyout server.key -out server.crt

我不知道我做错了什么.帮助会很棒.

I don't know what am I doing wrong. Help would be great.

### 更新 ###

这是 cURL 请求.在我看来，没有问题，还是我错了?

Here is the cURL request. In my opinion, there is no problem, or am I wrong?

curl -X GET https://localhost:3443/message -k -v

抱歉回复晚了.这是两个调试打印:

Sorry for the late answer.Here are the two debugPrints:

请求调试打印:

$ curl -i
  -H "Accept-Language: en-US;q=1.0"
  -H "Accept-Encoding: gzip;q=1.0,compress;q=0.5"
  -H "User-Agent: Message/com.teawithfruit.Message (1; OS Version 9.0 (Build 13A340))"
  "https://localhost:3443/message"

结果调试打印:

这是可能是 ATS 问题的完整错误?

Here is the complete error with maybe an ATS problem?

推荐答案

您需要在创建 ServerTrustPolicy 字典时添加 port 域.

You need to add the port domain when you create your ServerTrustPolicy dictionary.

let defaultManager: Alamofire.Manager = {
    let serverTrustPolicies: [String: ServerTrustPolicy] = [
        "localhost:3443": .DisableEvaluation
    ]

    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.HTTPAdditionalHeaders = Alamofire.Manager.defaultHTTPHeaders

    return Alamofire.Manager(
        configuration: configuration,
        serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies)
    )
}()
