使用Gsoap创建WebService

(c++)

1.         下载编译Gsoap

gSOAP工具包是用于SOAP和REST XML Web服务以及通用C / C ++ XML数据绑定的C和C ++软件开发工具包。 该工具包分析WSDL和XML模式（单独或作为组合集），并将XML模式类型和SOAP / REST XML消息传递协议映射为易于使用且高效的C和C ++代码。 它还支持通过自动生成XML序列化代码和WSDL规范将（传统）C和C ++应用程序作为XML Web服务公开。

下载Gsoap2.8：Gsoap下载地址：https://sourceforge.net/projects/gsoap2/files

解压，编译，安装后，

解压目录/gsoap/目录下，找到stdsoap2.c，stdsoap2.cpp，stdsoap2.h三个文件，后续需要引入。

2.         编写webservice所需头文件

2.1 编写imageRg.h文件，实例如下：（标注区域都需要根据实际情况替换）

//gsoap ns service name: imageRg 

//gsoap ns service namespace: http://localhost/imageRg.wsdl 

//gsoap ns service location: http://localhost 

//gsoap ns service executable: imageRg.cgi  

//gsoap ns service encoding: encoded 

//gsoap ns schema namespace: urn:imageRg 

int ns__getPlateID(std::string imgdata, std::string &plateID);

2.2 根据gosap工具生成源文件

Soapcpp2是一个根据.h文件生成若干支持webservice的代码生成工具，生成的代码文件包括webservice客户端和服务器的实现框架，XML数据绑定等，具体说明如下：

使用soapcpp2时，可选项如下： 

实例：

在头文件所在目录执行：

root@worker:/opt/workspace/gsoap_headfiles/test# soapcpp2 -S -j -T resq.h

3.         添加生成的gsoap相关源码到工程目录

添加步骤2生成的源码到工程目录，项目不需要引入动态库。

工程结构：

├── CMakeLists.txt

├── CMakeLists.txt.user

├── drivermonitorhandle.cpp

├── driverMonitor.wsdl

├── include

│   ├── base64vimg.h

│   ├── data.h

│   ├── driver_monitor.h

│   ├── drivermonitorhandle.h

│   ├── driverMonitor.nsmap

│   ├── glog

│   │   ├── …

│   ├── ns.xsd

│   ├── soapH.h

│   ├── soapStub.h

│   ├── stdsoap2.h

├── lib

├── soapC.cpp

├── soapServer.cpp

├── stdsoap2.cpp

最后添加请求处理逻辑到工程中。
