php 访问 Webservice (基于linux c/c++ gSOAP )

准备：

1.安装gSOAP库

2.参考网友资料生成web服务

一（通过端口访问web服务）

1）将安装好的gSOAP目录下的 stdsoap2.c 、stdsoap2.cpp、 stdsoap2.h、soapcpp2、wsdl2h文件拷到服务器目录下（地址自定义）

2）定义头文件（Standalone.h）

<span style="font-size:18px;">//gsoap ns service name:    add Simple StandaloneAdd service
//gsoap ns service style:    rpc
//gsoap ns service enconding:    encoded
//gsoap ns service namespace:    http://10.75.58.107/StandaloneAdd.wsdl
//gsoap ns service location:    http://10.75.58.107:18888

//gsoap ns schema namesapce:    urn:add

int ns__add(double a, double b, double *result);
</span>

头文件主要定义了服务的接口，注释部分不能缺少，这是定义即将生成的wsdl文件相关的属性（包括命名空间，服务所在位置，服务传送的方式等）

3）执行./soapcpp2 -c Standalone.h 生成与web服务相关的文件（命名空间，wsdl文件等,-c生成c文件）

 </port>
</service>

</definitions>
</span>

4）定义服务端文件（StandaloneAdd.c 实现头文件中的接口，并借助gSOAP 库函数处理特定的SOAP数据结构）

<span style="font-size:18px;">#include "soapH.h"
#include "add.nsmap"

int http_get(struct soap*soap) 
{ 
        FILE*fd = NULL;
        fd = fopen("add.wsdl", "rb"); //open WSDL file to copy
        if (!fd)
        {
                return 404; //return HTTP not found error
        }
        soap->http_content = "text/xml";  //HTTP header with text /xml content
        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; //cannot send, but little we can do about that
                }
        }
        fclose(fd);
        soap_end_send(soap);
        return SOAP_OK; 
} 

int main()
{
    struct soap soap;
    int master, slave;
    soap_init(&soap);
    soap.fget = http_get;
    master = soap_bind(&soap, "10.75.58.107", 18888, 100); 
    if(master < 0)
        soap_print_fault(&soap, stderr);
    else
    {
        //sprintf(stderr, "Socket connection successful:master socket = %d\n", master);
    	printf("Socket connection successful\n");
    while(1)
    {
        slave = soap_accept(&soap);
        if(slave < 0)
        {
            soap_print_fault(&soap, stderr);
            break;
        }
        //sprintf(stderr, "accepted connection from IP=%d.%d.%d.%d socket=%d",(soap.ip >> 24)&0xFF, (soap.ip >> 16)&0xFF, (soap.ip >> 8)&0xFF, soap.ip&0xFF, slave);
        if(soap_serve(&soap) != SOAP_OK)
            soap_print_fault(&soap, stderr);
        fprintf(stderr, "request served\n");
        soap_destroy(&soap);
        soap_end(&soap);
    }
    }
    soap_done(&soap);
}

int ns__add(struct soap *soap, double a, double b, double *result)
{
    *result = a + b;
    return SOAP_OK;
}
</span>

<span style="font-size:18px;">
</span>

5）定义客户端（ClientTest.c）

<span style="font-size:18px;">#include "soapH.h"
#include "add.nsmap"

const char server[] = "http://10.75.58.107:18888";

int main(int argc, char **argv)
{
    struct soap soap;
    double a, b, result;
    soap_init1(&soap, SOAP_XML_INDENT);
    a = strtod(argv[2], NULL);
    b = strtod(argv[3], NULL);
    
    soap_call_ns__add(&soap, server, "", a, b, &result);
    if(soap.error)
    {
        soap_print_fault(&soap, stderr);
        exit(1);
    }
    else
        printf("result = %g\n", result);
    soap_destroy(&soap);
    soap_end(&soap);
    soap_done(&soap);
    return 0;
    
}
</span>

6）编译服务端和客户端

gcc -o StandaloneAdd StandaloneAdd.c stdsoap2.c soapC.c soapServer.c

gcc -o ClientTest ClientTest.c stdsoap2.c soapC.c soapClient.c

7)开启服务

./StandaloneAdd

8)客户端连接webservice（本地远程皆可）

./ClientTest add 5 6

9)定义php客户端

<span style="font-size:18px;"><?php
	try{
		$soap = new SoapClient("http://10.75.58.107:18888/?wsdl");
		var_dump($soap);
		var_dump($soap->__getFunctions());
		echo $soap->add(1,5);                                  
	}catch(SoapFault $e){
		echo $e->getMessage();
	}catch(Exception $e){
		echo $e->getMessage();
	}
?>

</span>

（二）通过cgi访问web服务

定义头文件

<span style="font-size:18px;">// File: currentTime.h 
//gsoap ns service name: currentTime 
//gsoap ns service namespace: urn:currentTime 
//gsoap ns service location: http://10.75.58.73/currentTime.cgi 
int ns__currentTime(time_t& response);
</span>

生成wsdl文件

服务端文件

// File: currentTime.cpp 
#include "soapH.h" // include the generated declarations 
#include "currentTime.nsmap" // include the XML namespace mappings 
int main() 
{ 
   // create soap context and serve one CGI-based request: 
  return soap_serve(soap_new());
	// soap_destroy(&soap); // dealloc C++ data 
      	// soap_end(&soap);  
	// return 0;
} 
int ns__currentTime(struct soap *soap, time_t& response) 
{ 
   response = time(0); 
   return SOAP_OK; 
}

php访问

<?php

error_reporting(E_ALL);
ini_set('display_errors', true);
ini_set('display_startup_errors', true);


try{
   $soap = new SoapClient("http://10.75.58.73/cgi/currentTime.wsdl");
   // $soap = new SoapClient("http://10.75.58.190/webservice/add.wsdl");
	
	var_dump($soap);

	var_dump($soap->__getFunctions());
	//currentTime(currentTime $Body)
 	var_dump($soap->currentTime());
//echo $soap->add(11,15);
   
                                   
                                    
}catch(SoapFault $e){
    echo $e->getMessage();
}catch(Exception $e){
    echo $e->getMessage();
