如何讓這個 iOS Http Post 請求工作？

[英]How to get this iOS Http Post Request to work?

問題描述

我正在使用 Firebase Cloud Functions 和 Paypal 在我的應用程序中為司機設置付款流程。 要發布的 url 是 Firebase 中實際雲函數的 url：

https://us-central1-ryyde-sj.cloudfunctions.net/payout

嘗試發送 HTTP Post 請求時，它似乎不起作用。 請參閱下面的payoutRequest()和響應代碼：

支付請求（）

let email = txtPayoutEmail.text!
    let uid = self.uid!
    
    // Prepare URL:
    let url = URL(string: "https://us-central1-ryyde-sj.cloudfunctions.net/payout")
    guard let requestUrl = url else { fatalError() }
    
    // Prepare URL Request Object:
    var request = URLRequest(url: requestUrl)
    request.httpMethod = "POST"
    
    // Set HTTP Request Headers
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.setValue("Your Token", forHTTPHeaderField: "Authorization")
    request.setValue("no-cache", forHTTPHeaderField: "cache-control")

    print("request = \(request)")
    
    // HTTP Request Parameters which will be sent in HTTP Request Body:
    let postString = "uid=\(uid)&email=\(email)"
    print("postString = \(postString)")
     
    // Set HTTP Request Body
    request.httpBody = postString.data(using: String.Encoding.utf8)
    
    // Perform HTTP Request
    let task = URLSession.shared.dataTask(with: request) { (data, response, error ) in
        
        print("data: \(String(describing: data))")
        print("response: \(String(describing: response))")
        print("error: \(String(describing: error))")
        
        if let response = response as? HTTPURLResponse {
            // Read all HTTP Response Headers
            print("All headers: \(response.allHeaderFields)")
            // Read a specific HTTP Response Header by name
            if #available(iOS 13.0, *) {
                print("Specific header: \(response.value(forHTTPHeaderField: "Content-Type") ?? " header not found")")
            } else {
                // Fallback on earlier versions
            }
        }
        
        // Check for Errors
        if let error = error {
            print("Error took place \(error)")
            return
        }
        
        // Convert HTTP Response Data to a String
        if let data = data, let dataString = String(data: data, encoding: .utf8) {

如果請求成功，那么它將顯示在以下鏈接的 PayPal 沙盒通知中，但事實並非如此。

我在 PayPal HTTP 請求方面沒有太多經驗。

我已經做了與我在這里嘗試做的相同的事情，但是在 Android 中它運行良好，所以我知道這應該可以工作，而不是 Post Request （我嘗試使用在線示例來匹配我在 Android 應用程序中的內容）

嘗試這個：

    let body = ["uid": uid,
                "email": email]
     
    request.httpBody = try? JSONSerialization.data(withJSONObject: body, options: [])
