gsoap應用---利用gsoap工具生成代碼

1、gsoap是什麼?

          The gSOAP toolkit is an open source C and C++ software development toolkit forSOAP/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 toautomatically convert XML to/from C and C++ data. The toolkit supports options to generate pure ANSI C or C++ with or without STL.

        這是gsoap介紹的原文,簡單來說,gsoap就是一個工具,這個工具能夠做的事情就是自動從WSDL和XML文檔生成C/C++代碼,或者是逆向。這就是我所了解的gsoap。

記錄下:

        gSOAP編譯工具提供了一個SOAP/XML 關于C/C++ 語言的實作,進而讓C/C++語言開發web服務或用戶端程式的工作變得輕松了很多。絕大多數的C++web服務工具包提供一組API函數類庫來處理特定的SOAP資料結構,這樣就使得使用者必須改變程式結構來适應相關的類庫。與之相反,gSOAP利用編譯器技術提供了一組透明化的SOAP API,并将與開發無關的SOAP實作細節相關的内容對使用者隐藏起來。

  gSOAP的編譯器能夠自動的将使用者定義的本地化的C或C++資料類型轉變為符合XML文法的資料結構,反之亦然。這樣,隻用一組簡單的API就将使用者從SOAP細節實作工作中解脫了出來,可以專注與應用程式邏輯的實作工作了。gSOAP編譯器可以內建C/C++和Fortran代碼(通過一個Fortran到C的接口),嵌入式系統,其他SOAP程式提供的實時軟體的資源和資訊;可以跨越多個作業系統,語言環境以及在防火牆後的不同組織。

  gSOAP使編寫web服務的工作最小化了。gSOAP編譯器生成SOAP的代碼來序列化或反序列化C/C++的資料結構。gSOAP包含一個WSDL生成器,用它來為你的web服務生成web服務的解釋。gSOAP的解釋器及導入器可以使使用者不需要分析web服務的細節就可以實作一個用戶端或服務端程式。

2、gsoap使用

      gsoap通常帶有兩個工具: wsdl2h 和 soapcpp2。 wsdl2h主要是用來生成頭檔案的,而soapcpp2主要是利用wsdl2h生成的頭檔案來生成C檔案或C++檔案。

a、wsdl2h的使用

       指令:  wsdl2h  【-】  -o  頭檔案名  wsdl檔案名或者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常用選項

            -o 檔案名,指定輸出頭檔案

-n 名空間字首 代替預設的ns

-c 産生純C代碼,否則是C++代碼

-s 不要使用STL代碼

-t 檔案名,指定type map檔案,預設為typemap.dat

-e 禁止為enum成員加上名空間字首

              type map檔案用于指定SOAP/XML中的類型與C/C++之間的轉換規則,比如在wsmap.dat裡寫。

       關于typemap.dat,在下載下傳的gsoap中是有另外一個,叫:WS-typemap.dat。 如果有多個wsdl文檔,建議使用這個。

       wsdl2h針對多個文檔: wsdl2h.exe  -sc  -t   WS-typemap.dat   -o   quote.h    a.wsdl  b.wsdl   c.wsdl

   b、soapcpp2的使用

       指令: soapcpp2  【】  頭檔案名 【-I】 import路徑

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

       soapcpp2常用選項

            -C  僅生成用戶端代碼

-S  僅生成服務端代碼

-c   産生純C代碼,否則是C++代碼

-L   不要産生soapClientLib.c和soapServerLib.c檔案

-I    指定import路徑

-x  不要産生XML示例檔案

            -i   生成C++包裝,用戶端為xxxxProxy.h(.cpp),伺服器端為xxxxService.h(.cpp)。

       soapcpp2針對多個文檔: soapcpp2  -L -c  quote.h   -I  E:\gsoap-2.8\gsoap\import

       其實多個wsdl合并隻需要在生成頭檔案的時候注意就可以了,源檔案是通過頭檔案得到的。
