java - Java 开发人员的 Paypal 预付款

Question

我想问一个简单的问题，我的客户已经购买了 PayPal Advance 支付账户，包括每月 5 美元的额外服务，例如支付集成到他们的网站。

我想问一下这个账号可以使用哪些功能？我已经在谷歌上搜索但没有找到相关信息。

我的客户要求所有的付款都在我的网站上完成，不要让用户重定向到 Paypal 官网进行任何购买。

我如何使用此帐户执行此操作，我可以使用哪些功能以及服务或 API？

Answer 1

这是您的问题的解决方案。只需按照以下几点进行操作即可。

1. 创建一个 Maven 网络应用程序。

2. 包含以下依赖

           <dependency>
             groupId>com.paypal.sdk</groupId>
                       <artifactId>adaptivepaymentssdk</artifactId>
                       <version>2.5.106</version>
             </dependency>
   

3.这是包含支付邮件到邮件的代码的类。

    public class PaymentTest {
    public static boolean fundtransferFromClientAcount() {

        PayRequest req = new PayRequest();
        RequestEnvelope requestEnvelope = new RequestEnvelope();
        requestEnvelope.setErrorLanguage("en_US");
        req.setRequestEnvelope(requestEnvelope);
        List<Receiver> receiver = new ArrayList<Receiver>();
        Receiver rec = new Receiver();
        /** (Required) Amount to be paid to the receiver */
        rec.setAmount(10.00);
        /**Reciever and Sender should be register on paypal with same emailid.*/
        rec.setEmail("Reciever Email Id");
        receiver.add(rec);
        ReceiverList receiverlst = new ReceiverList(receiver);
        req.setReceiverList(receiverlst);
        req.setSenderEmail("Sender Email");
        req.setActionType("PAY");
        req.setCancelUrl("Cancel Url");
        req.setCurrencyCode("USD");
        /** Here we need to give success url */
        req.setReturnUrl("return or success url");
        Map<String, String> configurationMap =Configuration.getAcctAndConfig();
        // Creating service wrapper object to make an API call by loading
        // configuration map.
        AdaptivePaymentsService service = new AdaptivePaymentsService(
                configurationMap);

                    Map<Object, Object> map = new LinkedHashMap<Object, Object>();
                    map.put("Ack", resp.getResponseEnvelope().getAck());

                    map.put("TimeStamp", resp.getResponseEnvelope()
                            .getTimestamp());

                    map.put("Payment Execution Status",
                            resp.getPaymentExecStatus());
                    if (resp.getDefaultFundingPlan() != null) {
                        /** Default funding plan. */
                        map.put("Default Funding Plan", resp

        return true;
    }

    public static void main(String[] args) {

        fundtransferFromClientAcount();
    }

}

4.配置文件

/**
 *  For a full list of configuration parameters refer in wiki page(https://github.com/paypal/sdk-core-java/wiki/SDK-Configuration-Parameters). 
 */
public class Configuration {

        // Creates a configuration map containing credentials and other required configuration parameters.
        public static final Map<String,String> getAcctAndConfig(){
                Map<String,String> configMap = new HashMap<String,String>();
                configMap.putAll(getConfig());

                // Account Credential
                configMap.put("acct1.UserName", "sandbox account username");
                configMap.put("acct1.Password", "sandbox account password");
                configMap.put("acct1.Signature", "sandbox account signature");
                configMap.put("acct1.AppId", "sandbox account generated AppId");

                // Sample Certificate credential
                // configMap.put("acct2.UserName", "certuser_biz_api1.paypal.com");
                // configMap.put("acct2.Password", "D6JNKKULHN3G5B8A");
                // configMap.put("acct2.CertKey", "password");
                // configMap.put("acct2.CertPath", "resource/sdk-cert.p12");
                // configMap.put("acct2.AppId", "APP-80W284485P519543T");

                // Sandbox Email Address
                configMap.put("sandbox.EmailAddress", "email address for sandbox");

                return configMap;
        }

        public static final Map<String,String> getConfig(){
                Map<String,String> configMap = new HashMap<String,String>();

                // Endpoints are varied depending on whether sandbox OR live is chosen for mode
                configMap.put("mode", "sandbox");

                // These values are defaulted in SDK. If you want to override default values, uncomment it and add your value.
                // configMap.put("http.ConnectionTimeOut", "5000");
                // configMap.put("http.Retry", "2");
                // configMap.put("http.ReadTimeOut", "30000");
                // configMap.put("http.MaxConnection", "100");
                return configMap;
        }
}

5.只需获取所有必需的参数即可正常工作。
