一. 賬號的配置
1. 在開發(fā)者控制臺選擇 Apps & Credentials
WX20240429-195206@2x.png2. 可以選擇Create APP，或者直接使用系統(tǒng)默認(rèn)的Default Application，點(diǎn)擊Default Application進(jìn)入詳情
1. API credentials
1.png
- ClientID發(fā)起支付請求需要這個(gè)去初始化
- Secret key 生成Authentication的時(shí)候需要
2. Sandbox account info

- 更多收付款賬號，點(diǎn)擊這里

這邊會有默認(rèn)的收付款賬號，當(dāng)然還可以自己創(chuàng)建
@personal.example.com結(jié)尾 - 付款 - 【發(fā)起支付請求時(shí)候登錄該賬號付款，之前付款一直用自己注冊Paypal賬號，而不是沙盒里的賬號，導(dǎo)致一直登錄不成功，一般測試都是在Sandbox環(huán)境】

這里主要勾選[Log in with PayPal],[Native Checkout SDK]，再點(diǎn)擊[Log in with PayPal]的Advanced Settings去配置
- Return URL 目前Paypal固定后綴格式：xxx.xxx.xx://paypalpay，一般xxx.xxx.xx設(shè)置為當(dāng)前App的包名(eg:com.PayPalAPP://paypalpay)
- Full name和Email勾選，Privacy policy URL和User agreement URL隨便填寫給地址就行
- PayPal account ID (payer ID)勾選
- 最底部的Enable customers who have not yet confirmed their email with PayPal to log in to your app.勾選
4. Sandbox Webhooks，可以配置支付完成Paypal通知我們后臺的回調(diào)URL，后臺開發(fā)去關(guān)注即可
二. 代碼集成
文檔中有三種拉起支付的方式 Card、Native payments、Web payments，具體區(qū)別查閱https://developer.paypal.com/docs/checkout/advanced/ios/集成文檔，這里展示下Native payments集成方式，吐槽下，官方集成文檔跟官方Demo演示的流程對不上，文檔上Native payments的登錄是SDK內(nèi)部實(shí)現(xiàn)，實(shí)際跑起來，登錄是APP內(nèi)拉系統(tǒng)瀏覽器去登錄的
pod 'PayPal/PayPalNativePayments
import PayPal
let config = CoreConfig(clientID: "CLIENT_ID", environment: .sandbox)
let payPalNativeClient = PayPalNativeCheckoutClient(config: config)
- CLIENT_ID 替換成自己的clientID**
- 發(fā)起支付
@objc func payPalButtonTapped() {
Task {
let orderID = "OrderID"
let request = PayPalNativeCheckoutRequest(orderID: orderID)
await self.payPalClient.start(request: request)
}
}
- 這里的Task必須加上，要不然會崩潰，這里是參考官方Demo的寫法
orderID生成，后臺還沒搭建的情況
- cURL方式，按照提示對Note: Encode CLIENT_ID:CLIENT_SECRET in Base64 before sending it in the API call.進(jìn)行Base64 Encode，一直都是提示404
- Postman的方式可以正確獲得token
{
"scope": "https://uri.paypal.com/services/payments/futurepayments",
"access_token": "A21AAJ09kg1kH6oObs6FS1zTHLg3F-scr8dPDM8Cx7upLHpXvgQUltDbG-_8Lg4UoPXIFCuKGu0Ac0sq4XkHqJzJT0Gc2-lbQ",

"nonce": "2024-04-30T06:03:15ZYvWdeI2c-t4b1J0bbIGA3qHPCmZkWyPNvl7JoVpGN4o"
}
- 把步驟一獲取的授權(quán)碼替換如下，并在終端中執(zhí)行
curl --location --request POST 'https://api-m.sandbox.paypal.com/v2/checkout/orders/' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer A21AAKY8fUjjesNQpycLWrkz9lITZoAF6bUaYRZ-JEG1Nbj0F6fiyxI1CtwurwhCt1Uezl5vL2_1VXmz9pkFwQfZwZN-7alVQ' \

應(yīng)答如下，0GW60266PC254253L即是我們需要的訂單號，這樣就是可以愉快的發(fā)起支付請求了
{
"id": "0GW60266PC254253L",
"status": "CREATED",
"links": [{
"href": "https://api.sandbox.paypal.com/v2/checkout/orders/0GW60266PC254253L",

總結(jié)
1. 發(fā)起支付動作，文檔上的示例
let payPalNativeClient = PayPalNativeCheckoutClient(config: config)
我是這么寫的，運(yùn)行時(shí)直接報(bào)異常
@objc func payPalButtonTapped() async {
let orderID = "0H807318BJ781474U"
let request = PayPalNativeCheckoutRequest(orderID: orderID)
await self.payPalClient.start(request: request)
}
看了官方Demo的寫法，修改成如下
@objc func payPalButtonTapped() {
Task {
let orderID = "0H807318BJ781474U"
let request = PayPalNativeCheckoutRequest(orderID: orderID)
await self.payPalClient.start(request: request)
}
}
