gsoap应用---利用gsoap工具生成代码

１、gsoap是什么？

          The gSOAP toolkit is an open source C and C++ software development toolkit for SOAP/XML Web services and generic (non-SOAP) C/C++ XML data bindings. The toolkit analyzes WSDLs and XML schemas (separately or as a combined set) and maps the XML schema types and the SOAP messaging protocols to easy-to-use and efficient C and C++ code. It also supports exposing (legacy) C and C++ applications as SOAP/XML Web services by auto-generating XML serialization code and WSDL specifications. Or you can simply use it to automatically convert XML to/from C and C++ data. The toolkit supports options to generate pure ANSI C or C++ with or without STL.

        这是gsoap介绍的原文，简单来说，gsoap就是一个工具，这个工具能够做的事情就是自动从WSDL和XML文档生成C/C++代码，或者是逆向。这就是我所理解的gsoap。

记录下：

        gSOAP编译工具提供了一个SOAP/XML 关于C/C++ 语言的实现，从而让C/C++语言开发web服务或客户端程序的工作变得轻松了很多。绝大多数的C++web服务工具包提供一组API函数类库来处理特定的SOAP数据结构，这样就使得用户必须改变程序结构来适应相关的类库。与之相反，gSOAP利用编译器技术提供了一组透明化的SOAP API，并将与开发无关的SOAP实现细节相关的内容对用户隐藏起来。

　　gSOAP的编译器能够自动的将用户定义的本地化的C或C++数据类型转变为符合XML语法的数据结构，反之亦然。这样，只用一组简单的API就将用户从SOAP细节实现工作中解脱了出来，可以专注与应用程序逻辑的实现工作了。gSOAP编译器可以集成C/C++和Fortran代码（通过一个Fortran到C的接口），嵌入式系统，其他SOAP程序提供的实时软件的资源和信息；可以跨越多个操作系统，语言环境以及在防火墙后的不同组织。

　　gSOAP使编写web服务的工作最小化了。gSOAP编译器生成SOAP的代码来序列化或反序列化C/C++的数据结构。gSOAP包含一个WSDL生成器，用它来为你的web服务生成web服务的解释。gSOAP的解释器及导入器可以使用户不需要分析web服务的细节就可以实现一个客户端或服务端程序。

 

2、gsoap使用

      gsoap通常带有两个工具： wsdl2h 和 soapcpp2。 wsdl2h主要是用来生成头文件的，而soapcpp2主要是利用wsdl2h生成的头文件来生成C文件或C++文件。

 

 

  a、wsdl2h的使用

       命令：  wsdl2h  【-】  -o  头文件名  wsdl文件名或者url

       例    ：  wsdl2h  -o  quote.h    http://services.xmethods.net/soap/urn:xmethods-delayed-quotes.wsdl

       Usage: wsdl2h  [-a] [-c] [-d] [-e] [-f] [-g] [-h] [-I path] [-j] [-l] [-m] [-n name] [-N name] [-p] [-q name] [-r proxyhost:port] [-s] [-t typemapfile.dat] [-u]
                                 [-v] [-w] [-x] [-y] [-z] [-o outfile.h] infile.wsdl infile.xsd  http://www... ...

 

     wsdl2h常用选项

            -o 文件名，指定输出头文件

            -n 名空间前缀 代替默认的ns

            -c 产生纯C代码，否则是C++代码

            -s 不要使用STL代码

            -t 文件名，指定type map文件，默认为typemap.dat

            -e 禁止为enum成员加上名空间前缀

              type map文件用于指定SOAP/XML中的类型与C/C++之间的转换规则，比如在wsmap.dat里写。

       关于typemap.dat，在下载的gsoap中是有另外一个，叫：WS-typemap.dat。 如果有多个wsdl文档，建议使用这个。

 

       wsdl2h针对多个文档： wsdl2h.exe  -sc  -t   WS-typemap.dat   -o   quote.h    a.wsdl  b.wsdl   c.wsdl

   b、soapcpp2的使用

       命令： soapcpp2  【】  头文件名 【-I】 import路径

       例   ：  soapcpp2   -L  -c  quote.h   -I  E:\gsoap-2.8\gsoap\import 

       soapcpp2常用选项

            -C  仅生成客户端代码

            -S  仅生成客户端代码

            -c   产生纯C代码，否则是C++代码

            -L   不要产生soapClientLib.c和soapServerLib.c文件

            -I    指定import路径

            -x  不要产生XML示例文件

            -i   生成C++包装，客户端为xxxxProxy.h(.cpp)，服务器端为xxxxService.h(.cpp)。

 

       soapcpp2针对多个文档： soapcpp2  -L -c  quote.h   -I  E:\gsoap-2.8\gsoap\import

       其实多个wsdl合并只需要在生成头文件的时候注意就可以了，源文件是通过头文件得到的。

 

      wsdl2h -sc -t WS-typemap.dat -o onvif.h deviceio.wsdl devicemgmt.wsdl imaging.wsdl media.wsdl ptz.wsdl

      soapcpp2 -L -c -x onvif.h -I D:\gsoap-2.8\gsoap\import
