搞 了一下午:

开发服务器程序,需使用gSOAP生成服务器端代码框架。我们有两种做法:

  1. 编写WSDL,使用wsdl2h生成头文件,再soapcpp2生成框架代码;
  2. 编写头文件,使用soapcpp2生成框架代码;

这两种方式,结果是一样的,最终都有产生头文件,并生成代码。不同在于,在项目的开发中需要维护的文件不同,前者是需要维护WSDL文件,后者维护头文件。

我个人觉得第二种方式更好用,不仅仅是少了个步骤,而是WSDL的语法太难写了,有点XSD的味道。而头文件的编写,更接近于程序员的思考方式,比如定义消息结构,定义接口名称等。

gSOAP是非常智能的,它利用C/C++的注释来获取信息,所以在手工编写的头文件中,注释是用用处的,常以// gsoap 名字空间 …开头。做为学习,我准备为php blog程序wordpress写一个web service接口,名字叫wpsoap。


给出代码:

root@ubuntu:/home/aries/Aries/gsoap# cat add.h 
//gsoapopt cw
//gsoap ns2 schema namespace: urn:add
//gsoap ns2 schema form: unqualified
//gsoap ns2 service name: add
//gsoap ns2 service type: addPortType
//gsoap ns2 service port:http://websrv.cs.fsu.edu/~engelen/addserver.cgi
//gsoap ns2 service namespace: urn:add
//gsoap ns2 service transport: http://schemas.xmlsoap.org/soap/http
//gsoap ns2  service method-style:      add rpc
//gsoap ns2  service method-encoding:   
//add http://schemas.xmlsoap.org/soap/encoding/
//gsoap ns2  service method-action:     add ""
int ns2__add( int num1, int num2, int* sum );

注意:注释的的内容也必须加上

执行soapcpp2 -c add.h


3 添加一个服务端 addserver.c

root@ubuntu:/home/aries/Aries/gsoap# cat addserver.c 
#include "soapH.h"
#include "add.nsmap"

int main(int argc, char **argv)
{
    int m, s;
    struct soap add_soap;
    soap_init(&add_soap);
    soap_set_namespaces(&add_soap, namespaces);

    if (argc  /n", argv[0]);
        exit(1);
    } else {
        m = soap_bind(&add_soap, NULL, atoi(argv[1]), 100);
        if (m 

4 t添加 客服端 addclient.c

root@ubuntu:/home/aries/Aries/gsoap# cat addclient.c
#include "soapStub.h"
#include "add.nsmap"

int add(const char *server, int num1, int num2, int *sum)
{
    struct soap add_soap;
    int result = 0;
    soap_init(&add_soap);
    soap_set_namespaces(&add_soap, namespaces);
    soap_call_ns2__add(&add_soap, server, NULL, num1, num2, sum);
    printf("server is %s, num1 is %d, num2 is %d/n", server, num1, num2);

    if (add_soap.error) {
        printf("soap error: %d, %s, %s/n", add_soap.error, *soap_faultcode(&add_soap), *soap_faultstring(&add_soap));
        result = add_soap.error;
    }
    soap_end(&add_soap);
    soap_done(&add_soap);
    return result;
}

5 测试 上面的addtest.c

root@ubuntu:/home/aries/Aries/gsoap# cat addtest.c
#include 
#include 
#include 

int add(const char *server, int num1, int num2, int *sum);
int main(int argc, char **argv)
{
    int result = -1;
    char server[128] = {0};
    int num1;
    int num2;
    int sum;

    if (argc  num1 num2 /n", argv[0]);
        exit(1);
    }

    strcpy(server,argv[1]);
    num1 = atoi(argv[2]);
    num2 = atoi(argv[3]);
    result = add(server, num1, num2, &sum);

    if (result != 0) {
        printf("soap error, errcode=%d/n", result);
    } else {
        printf("%d + %d = %d/n", num1, num2, sum);
    }
    return 0;
}

注意:编译的时候我们需要gsoap包里的源代码文件,把stdsoap2.c和stdsoap2.h文件拷贝到当前目录


6 makefile

root@ubuntu:/home/aries/Aries/gsoap# cat makefile
GSOAP_ROOT = /mnt/hgfs/E/gsoap_2.8.17/gsoap-2.8/gsoap
WSNAME = add
CC = g++ -g -DWITH_NONAMESPACES
INCLUDE = -I$(GSOAP_ROOT)
SERVER_OBJS = soapC.o stdsoap2.o soapServer.o $(WSNAME)server.o 
CLIENT_OBJS = soapC.o stdsoap2.o soapClient.o $(WSNAME)client.o $(WSNAME)test.o

all: server
server: $(SERVER_OBJS) 
	$(CC) $(INCLUDE) -o $(WSNAME)server $(SERVER_OBJS) 

client: $(CLIENT_OBJS) 
	$(CC) $(INCLUDE) -o $(WSNAME)test $(CLIENT_OBJS)

cl:
	rm -f *.o *.xml *.a *.wsdl *.nsmap soapH.h $(WSNAME)Stub.* $(WSNAME)server ns.xsd $(WSNAME)test

root@ubuntu:/home/aries/Aries/gsoap# make
g++ -g -DWITH_NONAMESPACES    -c -o soapC.o soapC.c
g++ -g -DWITH_NONAMESPACES    -c -o stdsoap2.o stdsoap2.c
g++ -g -DWITH_NONAMESPACES    -c -o soapServer.o soapServer.c
g++ -g -DWITH_NONAMESPACES    -c -o addserver.o addserver.c
g++ -g -DWITH_NONAMESPACES -I/mnt/hgfs/E/gsoap_2.8.17/gsoap-2.8/gsoap -o addserver soapC.o stdsoap2.o soapServer.o addserver.o  

继续 make client


最后 文件如下:

add.add.req.xml  addserver    makefile         soapH.h          stdsoap2.h
add.add.res.xml  addserver.c  soapC.c          soapServer.c     stdsoap2.o
addclient.c      addserver.o  soapClient.c     soapServerLib.c
addclient.o      
addtest      soapClientLib.c  soapServer.o
add.h            addtest.c    soapClient.o     soapStub.h
add.nsmap        addtest.o    soapC.o          stdsoap2.c
