WSDL.exe生成服务代理框架

今天下午，终于用这个WSDL.exe生成代理框架了。

 

我有三个文件 stockquoteservice.wsdl 主文件 引用了（import） stockquote.wsdl ，后者又引用了（import） stockquote.xsd

<?xml version="1.0"?><definitions targetNamespace="http://example.com/stockquote/service" xmlns:tns="http://example.com/stockquote/service" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:defs="http://example.com/stockquote/definitions" xmlns="http://schemas.xmlsoap.org/wsdl/"> <import namespace="http://example.com/stockquote/definitions" location="stockquote.wsdl"/> <binding name="StockQuoteSoapBinding" type="defs:StockQuotePortType"> <soap:binding style="document" mce_style="document" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="GetLastTradePrice"> <soap:operation soapAction=""/> <input> <soap:body use="literal"/> </input> <output> <soap:body use="literal"/> </output> </operation> </binding> <service name="StockQuoteService"> <documentation>My first service</documentation> <port name="StockQuotePort" binding="tns:StockQuoteSoapBinding"> <soap:address location="http://example.com/stockquote"/> </port> </service></definitions> 

<?xml version="1.0"?><definitions targetNamespace="http://example.com/stockquote/definitions" xmlns:tns="http://example.com/stockquote/definitions" xmlns:xsd1="http://example.com/stockquote/schemas" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns="http://schemas.xmlsoap.org/wsdl/"> <import namespace="http://example.com/stockquote/schemas" location="http://example.com/stockquote/stockquote.xsd"/> <message name="GetLastTradePriceInput"> <part name="body" element="xsd1:TradePriceRequest"/> </message> <message name="GetLastTradePriceOutput"> <part name="body" element="xsd1:TradePrice"/> </message> <portType name="StockQuotePortType"> <operation name="GetLastTradePrice"> <input message="tns:GetLastTradePriceInput"/> <output message="tns:GetLastTradePriceOutput"/> </operation> </portType></definitions> 

<?xml version="1.0"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://example.com/stockquote/schemas" xmlns="http://www.w3.org/2001/XMLSchema"> <xs:element name="TradePriceRequest"> <xs:complexType> <xs:all> <xs:element name="tickerSymbol" type="xs:string"/> </xs:all> </xs:complexType> </xs:element> <xs:element name="TradePrice"> <xs:complexType> <xs:all> <xs:element name="price" type="xs:float"/> </xs:all> </xs:complexType> </xs:element></xs:schema> 

刚开始的时候 我直接在命令行里 敲 “wsdl  目录/tockquoteservice.wsdl ” 出现错误

 

说导入的命名空间下的一个类型没有定义，导入的命名空间显得服务描述已经丢失    

 

我刚赶紧检查一遍wsdl定义 好像也没什么错误  难道wsdl.exe只支持简单的 一个文件的契约定义，我想当然是不会

 

然后 我 查阅了 impot 相关资料 找到一篇（http://www.ibm.com/developerworks/cn/webservices/ws-tip-imports.html）

里面说:import 语句有两种类型：XSD 导入和 WDSL 导入

 

<xsd:import namespace="urn:listing3" schemaLocation="listing3.xsd">

 

<wsdl:import namespace="urn:listing5" location="listing5.wsdl"/>

 

 

前者的schemaLocation 属性是个可选属性，即使你用它提供了文件位置，XML 解析器也能够忽略该位置，schemaLocation 属性只不过是一个提示（hint）。XSD import 语句的主要目的是导入命名空间，而不是告诉您在命名空间的何处可以找到这些声明。

 

后者中WSDL 导入的 location 属性与 XSD 导入的 schemaLocation 属性相似，只不过是一个提示。不同的是，WSDL 导入的 location 属性是必须给出的，而不是可选属性。

 

看到这里 我有点明白了 原来我一直以为 wsdl.exe 工具 会根据schemaLocation 和location自动载入所应用的wsdl和xsd，看来不是，这两个属性仅仅是提示。

 

然后我就试着在命令行里把三个文件都列出来：

 

“wsdl  目录/tockquoteservice.wsdl  目录/tockquote.wsdl  目录/tockquote.xsd”

 

这次OK了。

生成的c#代码如下：
