Question

需要执行发布请求才能完成oauth2.0身份验证。

它在卷曲时效果很好：

curl -i -X POST -H 'Content-Type: application/x-www-form-urlencoded' -d 'clientId=cgoxyBxM1KVO3pLm5J7VgDVxlP7_33BpPlPXeIaSmoLsTZq8DfyM1svTwi-SU7KJKBRN4V3mIsV7pNNEg610Xw' https://fmsauth.scania.com/auth/S2S4DA/ClientId2Challenge

我得到这种回应：

{"challenge":"_jEEFcI36cvfMac8BHG8R0iIp4g7I-t0-C9LKAjwl9Y"}

我很快尝试了同样的事情，但返回的响应为零：

import Foundation

let session = URLSession.shared
let url = URL(string: "https://fmsauth.scania.com/auth/S2S4DA/ClientId2Challenge")!

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
let payload = Data("clientId=cgoxyBxM1KVO3pLm5J7VgDVxlP7_33BpPlPXeIaSmoLsTZq8DfyM1svTwi-SU7KJKBRN4V3mIsV7pNNEg610Xw".utf8)

let task = session.uploadTask(with: request, from: payload) { data, response, error in

    if let data = data, let dataString = String(data: data, encoding: .utf8) {
        print(dataString)
    }

    if let httpResponse = response as? HTTPURLResponse {
        print(httpResponse.statusCode)
    }
}

task.resume()

我认为有效载荷数据字符串可能存在问题。我不知道http帖子请求“数据格式”在卷曲和迅捷中是什么样子。

好吧，在阅读您的评论之后，这是怎么回事，该程序在您的代码甚至没有执行之前就已结束。一种简单的查看方法是在代码中添加断点。

您可以使用信号量来阻止当前线程，并等待URL会话结束。

调度信号量是传统方法的有效实现计数信号量。调度信号仅调用内核当调用线程需要被阻塞时。如果调用信号量不需要阻止，无需进行内核调用。 Apple

此代码将执行您想要的操作。

var sema = DispatchSemaphore( value: 0 )
let session = URLSession.shared
let url = URL(string: "https://fmsauth.scania.com/auth/S2S4DA/ClientId2Challenge")!

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
let payload = Data("clientId=cgoxyBxM1KVO3pLm5J7VgDVxlP7_33BpPlPXeIaSmoLsTZq8DfyM1svTwi-SU7KJKBRN4V3mIsV7pNNEg610Xw".utf8)

    let task = session.uploadTask(with: request, from: payload) { data, response, error in

        if let data = data, let dataString = String(data: data, encoding: .utf8) {
            print(dataString)
             sema.signal()
        }

        if let httpResponse = response as? HTTPURLResponse {
            print(httpResponse.statusCode)
        }
    }

    task.resume()
    sema.wait()

您的代码有效，我认为您需要启用传输。将此添加到info.plist

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>somethingthatshouldntworkyourdomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>
