URLSession POST呼叫

Question

我对URLSession没有太多的经验，但我正在尝试打一个POST电话，而且我一直收到两个不同的错误。

这是我的功能：

func test() {
    let parameters = ["username": "myUsername", "password": "myPassword"]
    guard let url = URL(string: "https://example.com:443/Auth/") else { return }
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else { return }
    request.httpBody = httpBody

    let session = URLSession.shared
    session.dataTask(with: request) { (data, response, error) in
        if let response = response {
            print(response)
        }
        if let data = data {
            do {
                let json = try JSONSerialization.jsonObject(with: data, options: [])
                print(json)
            } catch {
                print(error)
            }
        }
    }.resume()
}

下面是我遇到的错误：

第一个有一个堆栈溢出链接：CredStore Perform Query error。我添加了他们说要添加的代码，但是我最后也出现了同样的错误。

CredStore - performQuery - Error copying matching creds.  Error=-25300, query = {
    class = inet;
    "m_Limit" = "m_LimitAll";
    ptcl = htps;
    "r_Attributes" = 1;
    sdmn = "/Auth/";
    srvr = "example.com";
    sync = syna; 
}

我得到的下一个错误是：

<NSHTTPURLResponse: 0x600000b94180> { URL: https://example.com:443/Auth/ } { Status Code: 401, Headers {
"Content-Length" =     (
    31
);
"Content-Type" =     (
    "text/plain"
);
Date =     (
    "Mon, 24 Sep 2018 23:16:45 GMT"
);
"Www-Authenticate" =     (
    "Basic realm=\"/Auth/\""
);
} }
Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set." UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}

我收到了401个未经授权的错误。我看到它给我401的唯一原因是它没有正确读取用户名/密码？我不确定标题标题“用户名”和“密码”是否正确。实际的用户名和密码是绝对正确的。

对于遇到这个问题的人：

我想出了什么问题：

func test() {
    let username = "myUsername"
    let password = "myPassword"
    let loginString = String(format: "%@:%@", username, password)
    let loginData = loginString.data(using: String.Encoding.utf8)!
    let base64LoginString = loginData.base64EncodedString()

    let url = URL(string: "https://example.com:443/Auth/")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

    let session = URLSession.shared
    session.dataTask(with: request) { (data, response, error) in
        if let response = response {
            print(response)
        }
        if let data = data {
            do {
                let json = try JSONSerialization.jsonObject(with: data, options: [])
                print(json)
            } catch {
                print(error)
            }
        }
        }.resume()
}

我的用户名和密码被作为纯文本发送进来。必须将我的凭据编码为base64。
