c 处理基于java服务端byte[]数组接收图片( xsd__base64Binary)
背景：java端基于webservice实现服务端，c作为客户端，通过gsoap传输图片给服务端。
实现步骤：
1、c端通过服务端wsdl文件生成客户端代码，图片接收部分的结构体如下：
struct xsd__base64Binary{
unsigned char *__ptr;
int __size;
char *id; /* optional element of type xsd:string */
char *type; /* optional element of type xsd:string */
char *options; /* optional element of type xsd:string */
};2、读取图片数据，并赋值给次结构体
merchantLogoByte.__ptr = soap_malloc( &add_soap, size);
memcpy(merchantLogoByte.__ptr, data, size); //data 图片数据
merchantLogoByte.__size = size; //size图片大小
3、代码示例
#include
#include
#include
#include "AppWebServiceSoapBinding.nsmap"
#include "soapH.h"
#include "soapStub.h"
#define BUFSIZE 10240
