gsoap+URL自动生成头文件与客户端代码流程

1、下载gsoap代码下载链接 https://download.csdn.net/download/u011186256/10711057

    下载以后解压，进入\gsoap-2.8\gsoap-2.8\gsoap\bin\win32这个目录下面有两个执行文件soapcpp2.exe 与wsdl2h.exe

    wsdl2h.exe这个是生成头文件的

    soapcpp2.exe这个是生成代码的。

2、以天气预报的url为例生成头文件

    天气预报的URL：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

3、cmd命令进入wsdl2h.exe这个所在的目录然后运行

命令解释：
wsdl2h -o 头文件名 WSDL文件名或URL
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

  运行命令：.\wsdl2h -o test.h http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

生成test.h头文件，正常运行打印如下：

gsoap-2.8\gsoap-2.8\gsoap\bin\win32>.\wsdl2h -o test.h http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

Saving test.h

Cannot open file 'typemap.dat'

To complete the process, compile with:
> soapcpp2 test.h
or to generate C++ proxy and object classes:
> soapcpp2 -j test.h

根据提示运行soapcpp2 test.h或者soapcpp2 -j test.h会有错误提示如下：

Critical error: #import: Cannot open file "stlvector.h" for reading.
Hint: use option -I (you can define multiple paths separated with ';')

解决这个问题要将gsoap-2.8\gsoap\import下的soap12.h，stdsoap2.h,stlvector.h,与./gsoap/stdsoap2.cpp下的stdsoap.cpp这几个文件复制到wsdl2h.exe所在的目录下。

然后运行soapcpp2 -j test.h或者soapcpp2 test.h，运行以后正确打印结果如下：

Compilation successful

然后运行

soapcpp2 -i -C -x alldevices.h

soapcpp2常用选项：

-C 仅生成客户端代码 

-S 仅生成服务器端代码 

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

-c 产生纯C代码，否则是C++代码(与头文件有关) 

-I 指定import路径(视自己的解压包目录而定)；

-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)

生成相关的代码。

4、导入vs2015工程中，创建工程，去掉预编译头，与工程采用Unicode字符集如下面两个图。

然后导入项目，在VC里新建项目，找到项目所在文件夹，将生成的soapC.cpp，soapH.h，soapStub.h，XXXWebServiceSoapProxy.cpp，XXXWebServiceSoapProxy.h，XXX.nsmap以及gSOAP系统文件stdsoap2.cpp和stdsoap2.h文件复制到该项目文件夹，同时加载到工程中。

其中soapC.cpp，soapH.h，soapStub.h，XXXWebServiceSoapProxy.cpp，XXXWebServiceSoapProxy.h，XXX.nsmap这几个文件在soapcpp2.exe所在目录下。stdsoap2.cpp和stdsoap2.h这两个文件在gsoap-2.8\gsoap这个目录下。
