问题描述

我想在我的应用程序中使用贝宝作为付款流程.

I want to use paypal as a payment process in my application.

在paypal上，他们展示了许多使用REST API，经典api以及使用SOAP API的方法.

At paypal they have shown many ways as using REST API, classic api, and also using SOAP API.

我正在尝试通过以下方式使用SOAP客户端.

I am trying to use SOAP client by following way.

1.我正在尝试使用贝宝提供的wsdl文件创建一个SOAP Web服务客户端.但是，尽管创建客户端文件时，将客户端创建为无法重新获得该网址"时给我一个错误.

1.I am trying to create a SOAP web service client using paypal's provided wsdl file. But it's giving me error while creating client as ' unable to retieve that url',though it creates client files.

2.为proxyClass创建的对象，因为代理类包含所有必需的方法，例如getAuthDetails，setExpressCheckout，setEndPoint等.

2.Created object for proxyClass, as proxy class contains all required methods like getAuthDetails,setExpressCheckout,setEndPoint etc.

3.因此，这些方法包含诸如DetailLevelCodeType [] detailLevel，MessageElement [] _ any之类的参数.那么它的价值是什么?

3.So these method contains parameters like DetailLevelCodeType[]detailLevel,MessageElement[]_any. so what will be the value for it ?

4.根据我的理解，如果我要对Payapal进行任何操作，它应该询问我第一个身份验证参数，例如用户名，秘密，令牌，帐户密码. 对于使用rest api的Paypal，我知道通过提供用户凭据来获取访问令牌.

4.As per my understanding if I am performing any operation on payapal, it should ask me first authentication parameters like username,secret, token, password of my account. When it comes to paypal using rest api, I am aware about getting access token by providing user credentials.

So in soap web service client how to get that first? I didin't get any method available here for that.

但是我有一种方法可以从此链接执行授权. 安全凭据.

But I have got one way to perform authorization from this link. security credentials .

所以我遵循了这些步骤，现在我有了用户名密码.

So I followed these steps, now I have my username,password.

在下一个主题中，他们将说明，您的SOAP客户端必须设置用户名，密码元素，用于传递API用户名/密码 SOAP请求标头中的组合.

In next topic they are explaining , your SOAP client must set the Username, Password elements to pass an API username/password combination in the SOAP request header.

所以我正在尝试以这种方式在请求标头

So I am trying in this way to add username,password in request header reference.

此过程包括编组.

//到目前为止使用的软件包

//packages used so far

import javax.xml.ws.Binding;
import javax.xml.ws.BindingProvider;
import javax.xml.ws.handler.Handler;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBElement;
import javax.xml.bind.Marshaller;
import javax.xml.rpc.ServiceException;
import javax.xml.soap.SOAPHeader;




    public static void main(String[] args) {
        // TODO Auto-generated method stub


        PayPalAPIAAInterfaceProxy proxy=new PayPalAPIAAInterfaceProxy();

    //  proxy.setEndpoint("");

        // following class is generated by wsdl2java utility Service class
        final PayPalAPIInterfaceService payPalService = new PayPalAPIInterfaceServiceLocator();
        PayPalAPIAAInterface expressCheckoutPort;
        try {
            expressCheckoutPort = payPalService.getPayPalAPIAA();
            final Binding binding = ((BindingProvider) expressCheckoutPort).getBinding();
            List<Handler> handlersList = new ArrayList<Handler>();

            // now, adding instance of Handler to handlersList which should do our job:
            // creating header instance
            final CustomSecurityHeaderType headerObj = new CustomSecurityHeaderType();
            final UserIdPasswordType credentials = new UserIdPasswordType();
            credentials.setUsername("username");
            credentials.setPassword("password");
            credentials.setSignature("signature");
            headerObj.setCredentials(credentials);


            // bookmark #1 - please read explanation after code
            final ObjectFactory objectFactory = new ObjectFactory();
            // creating JAXBElement from headerObj
            final JAXBElement<CustomSecurityHeaderType> requesterCredentials = objectFactory.createRequesterCredentials(headerObj);

            handlersList.add(new SOAPHandler<SOAPMessageContext>() {
                @Override
                public boolean handleMessage(final SOAPMessageContext context) {        
                    try {
                        // checking whether handled message is outbound one as per Martin Strauss answer
                        final Boolean outbound = (Boolean) context.get("javax.xml.ws.handler.message.outbound");
                        if (outbound != null && outbound) {
                            // obtaining marshaller which should marshal instance to xml
                            final Marshaller marshaller = JAXBContext.newInstance(CustomSecurityHeaderType.class).createMarshaller();
                            // adding header because otherwise it's null
                            final SOAPHeader soapHeader = context.getMessage().getSOAPPart().getEnvelope().addHeader();
                            // marshalling instance (appending) to SOAP header's xml node
                            marshaller.marshal(requesterCredentials, soapHeader);
                        }
                    } catch (final Exception e) {
                        throw new RuntimeException(e);
                    }
                    return true;
                }

                // ... default implementations of other methods go here

            });

            // as per Jean-Bernard Pellerin's comment setting handlerChain list here, after all handlers were added to list
            binding.setHandlerChain(handlersList);


        } catch (ServiceException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }




    }

但是我发现缺少名为ObjectFactory的文件.

But I observed a file is missing named ObjectFactory .

我也包括了Merchant api sdk的jar文件.在我的网络服务中客户端此文件不存在.

I have included Merchant api sdk's jar file also. And in my web service client this file is not present.

因此有人可以在这种情况下指导我为什么文件没有得到从wsdl文件创建客户端时创建的文件?

So can anybody guide me in this context that why file is not getting created when creating client from wsdl file ?

我也曾尝试使用wsdl到Java插件来创建Web服务客户端，但这给了我

I have also tried to create web service client using wsdl to java plugin, but it is giving me error as

wsdlexception错误代码other_error，也说 FileNotFoundException

wsdlexception faultcode other_error ,it's also saying FileNotFoundException
