PayPal

具体API使用介绍，请参考gopay/paypal/client_test.go,gopay/paypal/order_test.go,gopay/paypal/payment_test.go

1、初始化PayPal客户端并做配置（Init PayPal Client）

  1. import (
  2.     "github.com/go-pay/gopay/paypal"
  3.     "github.com/go-pay/gopay/pkg/xlog"
  4. )
  6. // 初始化PayPal支付客户端
  7. client, err := paypal.NewClient(Clientid, Secret, false)
  8. if err != nil {
  9.     xlog.Error(err)
  10.     return
  11. }
  12. // 打开Debug开关，输出日志，默认关闭
  13. client.DebugSwitch = gopay.DebugOn

2、API 方法调用及入参（Call API）

Orders：Orders API

Payments：Payments API

  • Create Orders example
  1. import (
  2.     "github.com/go-pay/gopay"
  3.     "github.com/go-pay/gopay/paypal"
  4.     "github.com/go-pay/gopay/pkg/util"
  5.     "github.com/go-pay/gopay/pkg/xlog"
  6. )
  8. // Create Orders example
  9. var pus []*paypal.PurchaseUnit
  10. var item = &paypal.PurchaseUnit{
  11. ReferenceId: util.GetRandomString(16),
  12. Amount: &paypal.Amount{
  13. CurrencyCode: "USD",
  14. Value:        "8",
  15. },
  16. }
  17. pus = append(pus, item)
  19. bm := make(gopay.BodyMap)
  20. bm.Set("intent", "CAPTURE").
  21. Set("purchase_units", pus).
  22. SetBodyMap("application_context", func(b gopay.BodyMap) {
  23. b.Set("brand_name", "gopay").
  24. Set("locale", "en-PT").
  25. Set("return_url", "https://example.com/returnUrl").
  26. Set("cancel_url", "https://example.com/cancelUrl")
  27. })
  28. ppRsp, err := client.CreateOrder(ctx, bm)
  29. if err != nil {
  30. xlog.Error(err)
  31. return
  32. }
  33. if ppRsp.Code != paypal.Success {
  34. // do something
  35. return
  36. }
  • Capture payment for order
  1. import (
  2. "github.com/go-pay/gopay"
  3. "github.com/go-pay/gopay/pkg/xlog"
  4. )
  6. // Capture payment for order
  7. //bm := make(gopay.BodyMap)
  8. //bm.SetBodyMap("payment_source", func(b gopay.BodyMap) {
  9. //    b.SetBodyMap("token", func(b gopay.BodyMap) {
  10. //        b.Set("id", "The PayPal-generated ID for the token").
  11. //            Set("type", "BILLING_AGREEMENT")
  12. //    })
  13. //})
  14. ppRsp, err := client.OrderCapture(ctx, "4X223967G91314611", nil)
  15. if err != nil {
  16. xlog.Error(err)
  17. return
  18. }
  19. if ppRsp.Code != paypal.Success {
  20. // do something
  21. return
  22. }
