在 Java 中使用 SAAJ API 出现无效的内容类型错误

Question

我正在尝试使用 SAAJ 访问 SAOP API。 我遵循了与创建 SOAP 请求正文的其他答案中相同的代码，并且 调用 SOAP API。 此特定服务不需要任何身份验证（如 API 文档中所述），也不需要任何输入参数。

From WSDL: (copied only relevant content)

<xs:complexType name="getCustomerNames">
<xs:sequence/>
</xs:complexType> 
...
<wsdl:operation name="getCustomerNames">
<wsdl:input message="tns:getCustomerNames" name="getCustomerNames"/>
<wsdl:output message="tns:getCustomerNamesResponse" name="getCustomerNamesResponse"/>
<wsdl:fault message="tns:SOAPException" name="SOAPException"/>
</wsdl:operation>

下面是创建soap主体并调用API的Java代码

SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();
SOAPConnection connection = scf.createConnection();
SOAPFactory sf = SOAPFactory.newInstance();
String serverURI = "com.webservices.services.authentication";
MessageFactory mf =  MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL); // I tried without parameters as well
SOAPMessage message = mf.createMessage();
message.getSOAPHeader().detachNode();           
SOAPPart soapPart = message.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
envelope.addNamespaceDeclaration("auth", serverURI);
Name bodyName = sf.createName("getCustomerNames", "auth", serverURI);
SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
URL endpoint = new URL(urlendpoint); // urlendpoint is the one that I took from WSDL file service endpoint.
SOAPMessage response = connection.call(message, endpoint);
connection.close();

每当我执行此操作时，我都会收到以下错误消息。我不明白为什么.. 相同的 url 返回 当我从 Unix 执行 curl 命令并发布由上述 java 代码创建的相同请求 xml 时的正确响应。

SEVERE: SAAJ0537: Invalid Content-Type. Could be an error message instead of a SOAP message
com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Invalid Content-Type:text/html. Is this an error message instead of a SOAP response?

该错误意味着服务器使用 HTML 页面而不是 SOAP 响应进行响应。要对此进行调试，您需要拦截响应并查看 HTML 页面的内容；它可能包含有关该问题的更多信息。
