Linux下gSOAP的使用 (c++)

1、下载gSOAP在gSOAP官网中可以找到最新的gSOAP安装包以及相关的文档gSOAP官网：http://www.cs.fsu.edu/~engelen/soap.htmlgSOAP下载地址：http://sourceforge.net/projects/gsoap2/files/2、安装gSOAPa、解压zip压缩包命令：unzip gsoap_2.7.17.zipb、进入解压后生成的文件夹gsoap-2.7命令：cd gsoap-2.7/c、切换到root用户命令：su输入密码d、配置编译环境在gsoap-2.7/文件夹下有一个configure文件，执行它，自动配置编译环境命令：./configuree、编译连接命令：makef、安装gSOAP命令：make install可用wsdl2h或者soapcpp2查看gSOAP是否已经安装成功用命令whereis gsoap查看gSOAP安装到的位置3、编写calc.h文件a、新建一个文件夹calc命令：mkdir calcb、进入calc命令：cd calcc、创建文件calc.h,在文件中写入以下内容，保存//gsoap ns service name: calc Simple calculator service//gsoap ns service style: rpc//gsoap ns service encoding: encoded//gsoap ns service namespace: http://localhost/calc.wsdl//gsoap ns service location: http://localhost/server.cgi//gsoap ns schema namespace: urn:calcint ns__add(double a, double b, double *result);int ns__sub(double a, double b, double *result);int ns__mul(double a, double b, double *result);int ns__div(double a, double b, double *result);int ns__pow(double a, double b, double *result);注意：a、以上的几行注释中，gsoap ns service不能删除，但可以修改b、ns__add等的ns后面是两个下划线4、调用soapcpp2自动生成相关的文件(为了方便代码管理，在calc文件夹下新建一个soap)当前工作目录为calc/soap命令：soapcpp2 -i ../calc.h注意：可能会报错，一般是不知道gsoap相关include文件的位置，可以使用命令soapcpp2 -i ../calc.h -I /usr/include/gsoap5、编写服务器端代码：server.cpp当前工作目录：calc#include "soap/soapcalcService.h"

#include "soap/calc.nsmap"   //这个头文件不加的话，在链接的时候，stdsoap2.cpp里面会报无法引用namespaces#include <iostream>using namespace std;int main(int argc, char **argv) {calcService calc;int port = 65531;if (calc.run(port)) {cerr << "Calc service run failed" << endl;exit(0);}return 0;}int calcService::add(double a, double b, double* result) {*result = a + b;return SOAP_OK;}int calcService::sub(double a, double b, double* result) {*result = a - b;return SOAP_OK;}int calcService::mul(double a, double b, double* result) {*result = a * b;return SOAP_OK;}int calcService::div(double a, double b, double* result) {if (b) {*result = a / b;} else {return SOAP_FAULT;}return SOAP_OK;}int calcService::pow(double a, double b, double *result) {*result = ::pow(a, b);if (soap_errno == EDOM) {char *s = (char*) soap_malloc(this, 1024);sprintf(s, "Can't take the power of %f to %f", a, b);sprintf(s,"<error xmlns=\"http://tempuri.org/\">Can't take power of %f to %f</error>",a, b);return SOAP_FAULT;}return SOAP_OK;}6、编写客户端代码：client.cpp#include "soap/soapcalcProxy.h"#include "soap/calc.nsmap"#include <iostream>using namespace std;int main(int argc, char **argv) {double a = 4;double b = 2;double result;calcProxy calc;calc.soap_endpoint = "http://localhost:65531";calc.add(a,b,&result);cout<<a<<"+"<<b<<"="<<result<<endl;calc.sub(a,b,&result);cout<<a<<"-"<<b<<"="<<result<<endl;calc.mul(a,b,&result);cout<<a<<"*"<<b<<"="<<result<<endl;calc.div(a,b,&result);cout<<a<<"/"<<b<<"="<<result<<endl;calc.pow(a,b,&result);cout<<a<<"^"<<b<<"="<<result<<endl;return 0;}7、编写Makefile文件:makefile、sources.mk、subdir.mk、soap/subdir.mk、objects.mk新建bin文件夹当前工作目录：calc/bin#文件：makefileRM := rm -rf# 引入相关的生成文件-include sources.mk-include subdir.mk-include soap/subdir.mk-include objects.mkifneq ($(MAKECMDGOALS),clean)ifneq ($(strip $(C++_DEPS)),)-include $(C++_DEPS)endififneq ($(strip $(C_DEPS)),)-include $(C_DEPS)endififneq ($(strip $(CC_DEPS)),)-include $(CC_DEPS)endififneq ($(strip $(SERVER_CPP_DEPS)),)-include $(SERVER_CPP_DEPS)endififneq ($(strip $(CLIENT_CPP_DEPS)),)-include $(CLIENT_CPP_DEPS)endififneq ($(strip $(CXX_DEPS)),)-include $(CXX_DEPS)endififneq ($(strip $(C_UPPER_DEPS)),)-include $(C_UPPER_DEPS)endifendif# 生成目标all: server client# 相关工具server: $(SERVER_OBJS) $(USER_OBJS)@echo '创建目标: $@'g++  -o"server" $(SERVER_OBJS) $(USER_OBJS) $(LIBS)@echo '完成创建目标: $@'@echo "\n"client: $(CLIENT_OBJS) $(USER_OBJS)@echo '创建目标: $@'g++  -o"client" $(CLIENT_OBJS) $(USER_OBJS) $(LIBS)@echo '完成创建目标: $@'@echo "\n"# 清空临时文件clean:-$(RM) $(SERVER_OBJS)$(CLIENT_OBJS)$(C++_DEPS)$(C_DEPS)$(CC_DEPS)$(SERVER_CPP_DEPS)$(CLIENT_CPP_DEPS)$(EXECUTABLES)$(CXX_DEPS)$(C_UPPER_DEPS)-@echo "\n"cleanall:-$(RM) $(SERVER_OBJS)$(CLIENT_OBJS)$(C++_DEPS)$(C_DEPS)$(CC_DEPS)$(SERVER_CPP_DEPS)$(CLIENT_CPP_DEPS)$(EXECUTABLES)$(CXX_DEPS)$(C_UPPER_DEPS) server client-@echo "\n"cleanexe:-$(RM) server client-@echo "\n".PHONY: all clean dependents cleanall cleanexe=====================================================================================================#文件：sources.mkO_SRCS := SERVER_CPP_SRCS := CLIENT_CPP_SRCS :=C_UPPER_SRCS := C_SRCS := S_UPPER_SRCS := OBJ_SRCS := ASM_SRCS := CXX_SRCS := C++_SRCS := CC_SRCS := SERVER_OBJS := CLIENT_OBJS :=C++_DEPS := C_DEPS := CC_DEPS := SERVER_CPP_DEPS := CLIENT_CPP_SRCS :=EXECUTABLES := CXX_DEPS := C_UPPER_DEPS := #
