gsoap快速webservice服务开发

gsoap快速webservice服务开发

1、编写头文件test.h

//gsoap ns service name: test
//gsoap ns service protocol: SOAP
//gsoap ns service style: rpc
//gsoap ns service namespace: http://192.168.1.7:8888/test.wsdl
//gsoap ns service location: http://192.168.1.7:8888
//gsoap ns service encoding: encoded
//gsoap ns schema namespace: urn:test

int ns__add(int a,int b,int *r);

2、编写服务端文件test.c

#include "soapH.h"
#include "test.nsmap"

int http_get(struct soap *soap);
int main(int argc,char **argv)
{
    int m,s;    // 主、从套接字
    struct soap soap;
    soap_init(&soap);
    soap.fget = http_get;<span style="white-space:pre">	</span>//用于http请求wsdl文件
    soap_set_namespaces(&soap,namespaces);
    if(argc < 2)
        exit(-1);
    m = soap_bind(&soap,NULL,atoi(argv[1]),100);
    if(!soap_valid_socket(m))
    {   
        soap_print_fault(&soap,stderr);
        exit(-1);
    }   
    fprintf(stderr,"Socket connection successful: master socket = %d\n",m);
    for(;;)
    {   
        s = soap_accept(&soap);
        fprintf(stderr,"New socket connect: slave socket = %d\n",s);
        if(!soap_valid_socket(s))
        {   
            soap_print_fault(&soap,stderr);
            exit(-1);
        }   
        soap_serve(&soap);
        soap_end(&soap);
    }   
    return 0;
}

int ns__add(struct soap *soap,int n1,int n2,int *result)
{
    *result = n1 + n2;
    return SOAP_OK;
}

int http_get(struct soap *soap)
{
    FILE *fd = fopen("test.wsdl","rb");
    if(!fd)
        return 404;
    soap->http_content = "text/xml";
    soap_response(soap,SOAP_FILE);
    for(;;)
    {
        size_t r = fread(soap->tmpbuf,1,sizeof(soap->tmpbuf),fd);
        if(!r)
            break;
        if(soap_send_raw(soap,soap->tmpbuf,r))
            break;
    }
    fclose(fd);
    soap_end_send(soap);
    return SOAP_OK;
}

3、Makefile

GSOAP_ROOT=/usr/local/gSOAP
WSNAME=test

CC=g++ -g -DWITH_NONAMESPACES
INCLUDE=-I $(GSOAP_ROOT)/include
SERVER_OBJS=soapC.o soapServer.o stdsoap2.o
ALL_OBJS=${WSNAME}server.o soapC.o soapServer.o

all:server
${WSNAME}.wsdl:${WSNAME}.h
    $(GSOAP_ROOT)/bin/soapcpp2 -c $(GSOAP_ROOT)/import ${WSNAME}.h

stdsoap2.o:$(GSOAP_ROOT)/src/stdsoap2.c
    $(CC) -c $? $(INCLUDE)

$(ALL_OBJS):%.o:%.c
    $(CC) -c $? $(INCLUDE)

server:Makefile ${WSNAME}.wsdl ${WSNAME}server.o $(SERVER_OBJS)
    $(CC) $(WSNAME)server.o $(SERVER_OBJS) -o ${WSNAME}server

clean:
    rm -f *.o *.xml *.a *.wsdl *.nsmap \
    $(WSNAME0)H.h $(WSNAME0)C.c $(WSNAME0)Server.c $(WSNAME0)Client.c \
    $(WSNAME0)Stub.* $(WSNAME)$(WSNAME)Proxy.* $(WSNAME)$(WSNAME)Object.* \
    $(WSNAME0)ServerLib.c $(WSNAME0)ClientLib.c $(WSNAME)server ns.xsd $(WSNAME)test \
    soaP*.* stdsoaP*.*

4、生成执行文件后在指定端口启用

#./testserver 8888 &

5、浏览器输入：http://192.168.1.7:8888 可看到wsdl文件内容，C#可以直接使用该链接添加web服务引用。

PS：不用C++的原因是发现当前版本（2.8.23），C++的服务端代码只能直接调取服务方法，无法用http方式获取wsdl文件，且一旦有http请求过来，会导致服务器崩溃。

PS的PS：其实就两句代码搞定（当然，前提是正确安装了gsoap，请移步安装gSOAP）

1、生成通信层相关代码

#soapcpp2 -c -S -L /usr/local/gSOAP/import test.h

解释一下，-c 是生成C语言版本的代码，-S是仅生成服务端代码，-L是不生成soapClientLib或soapServerLib

2、编译可执行文件

g++ -g -DWITH_NONAMESPACES -o testserver testserver.c soapC.c soapServer.c /usr/local/gSOAP/src/stdsoap2.c -I /usr/local/gSOAP/include/#

可以看到就引用了三个gsoap文件，soapC.c soapServer.c stdsoap2.c 以及相应的头文件。
