[Webservice] The client calls to set the header

introduction

Before calling the webservice interface of other systems, the client was downloaded directly, and then developed according to the wsdl document

But this time, the interface that calls the erp system needs to set the header. There is no problem with the soapUI test, but there is a problem with the code implementation.

Because it is not written in the envelope, but directly in the header of the request, I tried many methods, and finally realized it, but other attempts may also be used next time, hereby record

 

HttpClient calling method

    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);

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

        }
    }

other attempts

1. Create a service from scratch

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

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

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

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

        // 2.创建Dispatch
        Dispatch<SOAPMessage> 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. Set the HandlerResolver method

part of the code

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

Reference blog: https://blog.csdn.net/East271536394/article/details/6699222

 

3. Set the SOAPHeader method

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");

None of the above will work, probably because the header is not in the envelope, but in the request

 

summary

I started to wonder why soapUI works and why the code doesn't work. After some research on soap, I
ended up imitating the browser to make calls like soapUI, so I could get data
. The attempts during this period also deepened my understanding of webservice.
