我已经在 PHP 中创建了一个 Web 服务,我正在尝试从我的 C# 代码中调用它。
当我尝试使用 wsdl 实用程序创建代理时
我得到了这个错误
Error: Cannot find definition for http://myserver.co.za/sayHello:sayHelloPortType.
Service Description with namespace http://myserver.co.za/sayHello is missing.
Parameter name: name
这是我的 Web 服务代码 (DemoService.php)
<?php
function sayHello($name){
$salutation = "Hi $name !";
return $salutation;
}
$server = new SoapServer("greetings.wsdl");
$server->addFunction("sayHello");
$server->handle();
?>
和我的 WSDL 代码 (greetings.wsdl)
<?xml version ='1.0' encoding ='UTF-8' ?>
<definitions name='greetings'
targetNamespace='http://myserver.co.za/sayHello'
xmlns:tns=' http://myserver.co.za/sayHello'
xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/'
xmlns:xsd='http://www.w3.org/2001/XMLSchema'
xmlns:soapenc='http://schemas.xmlsoap.org/soap/encoding/'
xmlns:wsdl='http://schemas.xmlsoap.org/wsdl/'
xmlns='http://schemas.xmlsoap.org/wsdl/'>
<message name='sayHelloRequest'>

<message name='sayHelloResponse'>
<part name='salutation' type='xsd:string'/>
</message>
<portType name='sayHelloPortType'>
<operation name='sayHello'>
<input message='tns:sayHelloRequest'/>
<output message='tns:sayHelloResponse'/>
</operation>
</portType>
<binding name='sayHelloBinding' type='tns:sayHelloPortType'>

</input>
<output>
<soap:body use='encoded' namespace=''
encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/>
</output>
</operation>
</binding>
<documentation>This is Wiley's SOAP server Example</documentation>
<service name='sayHelloService'>
<port name='sayHelloPort' binding='sayHelloBinding'>
<soap:address location='http://localhost:5365/DemoService.php'/>
</port>
</service>
</definitions>
我真的不明白它想说什么。有人能给我指出正确的方向吗?
最佳答案
这是 WSDL 的问题所在
首先是 xmlns:tns
命名空间在它的开头有一个空格
xmlns:tns=' http://myserver.co.za/sayHello' <-- Bad
xmlns:tns='http://myserver.co.za/sayHello' <-- Good
下一个 <documentation>
节点在错误的位置,它应该在 <service>
内像这样的节点
<service ...>
<documentation>This is Wiley's SOAP server Example</documentation>
<port ...>
...
</port>
</service>
您的端口绑定(bind)元素需要使用 tns
命名空间
<port name='sayHelloPort' binding='sayHelloBinding'> <-- Bad
<port name='sayHelloPort' binding='tns:sayHelloBinding'> <-- Good
最后我无法得到 soap:body
导入为 encoded
, 并且不得不将它们交换为 literal
, 还要注意他们需要 namespace
中的值元素
<soap:body use='literal' namespace='urn:xmethods-delayed-quotes' encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/>
我相信soapAction
<soap:operation soapAction=''/>
中的元素node 仍然需要一个值才能正常工作,比如 urn:xmethods-delayed-quotes#sayHello
, 但它会在没有它的情况下导入。
完整的 WSDL(我可以使用 WSDL.exe 导入它而不会出错)
<?xml version ='1.0' encoding ='UTF-8' ?>
<definitions name='greetings'
targetNamespace='http://myserver.co.za/sayHello'
xmlns:tns='http://myserver.co.za/sayHello'
xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/'
xmlns:xsd='http://www.w3.org/2001/XMLSchema'
xmlns:soapenc='http://schemas.xmlsoap.org/soap/encoding/'
xmlns:wsdl='http://schemas.xmlsoap.org/wsdl/'
xmlns='http://schemas.xmlsoap.org/wsdl/'>
<message name='sayHelloRequest'>
<part name='name1' type='xsd:string'/>
</message>
<message name='sayHelloResponse'>
<part name='salutation' type='xsd:string'/>
</message>
<portType name='sayHelloPortType'>
<operation name='sayHello'>
<input message='tns:sayHelloRequest'/>
<output message='tns:sayHelloResponse'/>
</operation>
</portType>
<binding name='sayHelloBinding' type='tns:sayHelloPortType'>
<soap:binding style='rpc' transport='http://schemas.xmlsoap.org/soap/http'/>
<operation name='sayHello'>
<soap:operation soapAction=''/>
<input>
<soap:body use='literal' namespace='urn:xmethods-delayed-quotes' encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/>
</input>
<output>
<soap:body use='literal' namespace='urn:xmethods-delayed-quotes' encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'/>
</output>
</operation>
</binding>
<service name='sayHelloService'>
<documentation>Service Description</documentation>
<port name='sayHelloPort' binding='tns:sayHelloBinding'>
<soap:address location='http://localhost:5365/DemoService.php'/>
</port>
</service>
