【Webservice】客户端调用设置header

引言

之前调用其它系统的webservice接口，都是直接下载客户端，然后根据wsdl文档进行开发

但是这次调用erp系统的接口需要设置header，本来才soapUI测试没什么问题，但是用代码实现就出了问题

因为它不是写在envelope里面，而是直接在请求中的header中，尝试了很多方法，最终实现了，不过其他的尝试或许下次也可以用，特此记录

 

HttpClient调用方式

    public static String postErpStock(String url, String pOrganizatoinCode, String pDataType) throws Exception {
        // 定义httpClient的实例
        CloseableHttpClient httpclient = HttpClients.createDefault();
        String retVal;
        try {
            HttpPost httpPost = new HttpPost(url);

            String wsdlData=
                    "" 
                    +"" 
                   +""
                   +""
                   +" "
                        +" "
                        +" "
                        +" "
                            +""
                              +" "
                               +""
                              +" "
                              +" "
                               +""
                               +""
                               +""
                              +" "
                              +" "
                              +" "
                              +" "
                              +" "
                              +" "
                           +" "
                        +" "
                       +"  "+pOrganizatoinCode+""
                        +" "+pDataType+""
                       +"  "
                     +" "
                  +" "
                +"";

            StringEntity myEntity = new StringEntity(wsdlData,   
                       ContentType.create("text/xml", "UTF-8"));  
             httpPost.setEntity(myEntity);

            httpPost.addHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");// 伪装一个浏览器
            httpPost.setHeader("LoginCode","123");
            httpPost.setHeader("LoginPassword","123");


            CloseableHttpResponse response2 = httpclient.execute(httpPost);
            try {
                HttpEntity entity2 = (HttpEntity) response2.getEntity();
                if (entity2 != null) {
                    retVal = EntityUtils.toString(entity2, "UTF-8");
                } else {
                    retVal = null;
                }
                EntityUtils.consume(entity2);
                return retVal;
            } finally {
                response2.close();
            }
        } finally {
            httpclient.close();
        }
    }

其他的尝试

1.从头开始创建服务

        String wsdlUrl = "http://IP:9099/org.URL/enh/invqty?WSDL";
        String namespaceUrl = "http://com/URL/Invqty.wsdl";

        // 1.创建服务
        Holder xReturnStatusOut = new Holder();
        xReturnStatusOut.value = "";
        Holder xMsgCountOut = new Holder();
        xMsgCountOut.value = new BigDecimal("0");
        Holder xMsgDataOut = new Holder();
        xMsgDataOut.value = "";

        InvqtyInvQtyRecUserArray invqtyInvQtyRecUserArray = new InvqtyInvQtyRecUserArray();
        invqtyInvQtyRecUserArray.getInvqtyInvQtyRecUser().add(new InvqtyInvQtyRecUser());
        Holder xInvQtyInfoOut = new Holder();
        xInvQtyInfoOut.value = invqtyInvQtyRecUserArray;

        Invqty_Service invqty_Service = new Invqty_Service();
        Invqty invqty = invqty_Service.getInvqtyPort();

        // 2.创建Dispatch
        Dispatch dispatch = invqty_Service.createDispatch(
                new QName("http://com/URL/Invqty.wsdl", "invqtyPort"), SOAPMessage.class,
                Service.Mode.MESSAGE);

        // 3.创建SOAPMessage
        SOAPMessage msg = MessageFactory.newInstance().createMessage();
        SOAPEnvelope envelope = msg.getSOAPPart().getEnvelope();
        SOAPBody body = envelope.getBody();

        // header信息
        SOAPHeader header = envelope.getHeader();
        if (header == null) {
            header = envelope.addHeader();
        }
        QName LoginCode = new QName(namespaceUrl, "LoginCode");
        QName LoginPassword = new QName(namespaceUrl, "LoginPassword");
        QName ClientId = new QName(namespaceUrl, "ClientId");
        QName OperationCode = new QName(namespaceUrl, "OperationCode");
        header.addHeaderElement(LoginCode).setValue("12");
        header.addHeaderElement(LoginPassword).setValue("12");
        header.addHeaderElement(ClientId).setValue("12");
        header.addHeaderElement(OperationCode).setValue("12");

        // 4.创建QName来指定消息中传递的数据
        QName ename = new QName(namespaceUrl, "list", "ns");
        body.addBodyElement(ename);
        msg.writeTo(System.out);
        System.out.println();

        // 5.通过Distpatch传递信息
        SOAPMessage responseMsg = dispatch.invoke(msg);
        responseMsg.writeTo(System.out);
        System.out.println();

        invqty.getInvQtyInfo(xReturnStatusOut, xMsgCountOut, xMsgDataOut, xInvQtyInfoOut, "11", "12", "");

2.设置HandlerResolver方法

部分代码

SOAPElement LoginCode = header.addChildElement("LoginCode");
LoginCode.addTextNode("");
SOAPElement LoginPassword = header.addChildElement("LoginPassword");
LoginPassword.addTextNode("");

参考博客：https://blog.csdn.net/East271536394/article/details/6699222

 

3.设置SOAPHeader方法

SOAPHeader header = envelope.getHeader();
if(header == null){
    header = envelope.addHeader();
}
QName LoginCode = new QName(namespaceUrl, "LoginCode", "ns");
QName LoginPassword = new QName(namespaceUrl, "LoginPassword", "ns");
header.addHeaderElement(LoginCode).setValue("444");      header.addHeaderElement(LoginPassword).setValue("123456");

header.addAttribute(new QName("LoginCode"), "enh_ws");
header.addAttribute(new QName("LoginPassword"), "123456");

header.setAttribute("LoginCode", "enh_ws");
header.setAttribute("LoginPassword", "123456");

以上都不行，原因大概是因为header不在envelope里面，而是在请求中

 

小结

开始在想为什么soapUI可以，为什么代码不可以，研究了一番soap之后
最后还是向soapUI一样，直接模仿浏览器进行调用，这样就可以获取数据
期间的尝试也也加深了自己对webservice的了解
