java - 尝试通过 Java 设置用户名和密码向 SOAP WsdlRequest 提交请求时出现 ClientProtocolException

Question

我的目的是使用给定的 wsdl URL 创建一个 Soap UI 项目，保存它并通过 Java 方法发送请求。当我org.apache.http.client.ClientProtocolException..... Caused by: org.apache.http.ProtocolException: Content-Length header already present尝试通过设置操作的用户名和密码来提交请求时出现错误。找到我的 Java 方法来发送请求。

public void runSoap() throws Exception
{
        String projectFile = "SoapUIProjects/TestProjectA-soapui-project.xml";
    SoapUI.setSoapUICore(new StandaloneSoapUICore(true));
    WsdlProject project = new WsdlProject(projectFile);

    int c = project.getInterfaceCount();
    System.out.println("The interface count   ="+c);

    for(int i=0;i<c;i++)
    {
        WsdlInterface wsdl = (WsdlInterface) project.getInterfaceAt(i);
        String soapVersion = wsdl.getSoapVersion().toString();
        int opc = wsdl.getOperationCount();
        String result="";

        for(int j=0;j<opc;j++)
        {
            WsdlOperation op = wsdl.getOperationAt(j);
                String opName = op.getName();
                System.out.println("OPERATION:"+opName);

                WsdlRequest req = op.getRequestByName("Req_"+soapVersion+"_"+opName);

                //Assigning correct u/p to an operation: Generate
                if(opName.equals("Generate"))
                {
                    System.out.println("The operation is Generate.");
                    req.setUsername("u1");//Setting username
                    req.setPassword("u1");//Setting password
               }

               WsdlSubmitContext wsdlSubmitContext = new WsdlSubmitContext(req);
               WsdlSubmit<?> submit = (WsdlSubmit<?>) req.submit(wsdlSubmitContext, false);
               Response response = submit.getResponse();
               result = response.getContentAsString();
               System.out.println("The result ="+result);
        }
    }
}

Answer 1

我得到了我的问题的答案。我必须以编程方式明确设置“授权类型”，这样做的代码是这样的 - req.setAuthType("Preemptive");

通过给出这个，请求被发送并且我没有得到任何异常。

Answer 2

In my search to fix this same error, I found that the solution was to enable "Authenticate Preemptively" option (go into preferences-> http settings and check the 'Authenticate Preemptively' box.)

Answer 3

1）在我的情况下， http在属性中配置而不是https。我 用https替换了http然后它的工作。

https://localhost:8102/WebService/test

2）检查授权用户名和密码

3) 选择 Pre-emptive auth: Authenticate pre-emptively
