gSOAP不正确的响应数据

我正试图在运行在Linux上的嵌入式系统上设置一个SOAP服务器，用于向它发送命令并获取响应。我选择使用gSOAP，因为我使用C编写代码。我编写了一个简单的gsoap服务器来运行我的嵌入式系统和客户端应用程序，以便在我的Linux PC上运行。现在我刚刚实现了服务器，因为它将请求中的命令数据复制到响应并发送。但是我在PC上收到的数据与我发送的数据不同。请帮忙。我重视我的服务器和客户端的代码gSOAP不正确的响应数据

页眉

struct data_packet 
{ 
    uint8_t *data; 
    int8_t data_length; 
}; 

int ns__send_command(struct data_packet cmd_packet, struct data_packet *resp_packet);

服务器

#include "soapH.h" // include the generated declarations 
#include "ns.nsmap" // include the XML namespace mappings 
int main() 
{ 
    struct soap soap; 
    int m, s, i; // master and slave sockets with loop variable 
    soap_init(&soap); 
    m = soap_bind(&soap, "10.0.0.10", 2012, 100); 
    if (m < 0) 
    soap_print_fault(&soap, stderr); 
    else 
    { 
    fprintf(stderr, "Socket connection successful: master socket = %d\n", m); 
    for (i = 1; ; i++) 
    { 
     s = soap_accept(&soap); 
     if (s < 0) 
     { 
      soap_print_fault(&soap, stderr); 
      break; 
     } 
    fprintf(stderr, "%d: accepted connection from IP=%d.%d.%d.%d socket=%d", i, 
     (int)(soap.ip >> 24)&0xFF, (int)(soap.ip >> 16)&0xFF, (int)(soap.ip >> 8)&0xFF, (int)soap.ip&0xFF, s); 
     if (soap_serve(&soap) != SOAP_OK) // process RPC request 
      soap_print_fault(&soap, stderr); // print error 
     fprintf(stderr, "request served\n"); 
     soap_destroy(&soap); // clean up class instances 
     soap_end(&soap); // clean up everything and close socket 
    } 
    } 
    soap_done(&soap); // close master socket and detach context 
} 

int ns__send_command(struct soap *soap, struct data_packet cmd_packet, struct data_packet *resp_packet) 
{ 
    resp_packet->data_length = cmd_packet.data_length; 
    resp_packet->data = (uint8_t*)soap_malloc(soap, sizeof(uint8_t*) * resp_packet->data_length); 
    memcpy(&resp_packet->data[0], &cmd_packet.data[0], resp_packet->data_length); 
    return SOAP_OK; 
}

客户

#include "soapH.h" 
#include "ns.nsmap" 

int main() 
{ 
    struct soap soap; 
    uint8_t cmd_ping[16] = {0x56, 0x69, 0x56, 0x4F, 0x70, 0x61, 0x79, 0x56, 0x33, 0x00, 0x18, 0x01, 0x00, 0x00, 0x04, 0x7E}; 

    struct data_packet cmd_packet; 
    struct data_packet resp_packet; 

    cmd_packet.data_length = 16; 
    cmd_packet.data = (uint8_t*)soap_malloc(&soap, sizeof(uint8_t*) * cmd_packet.data_length); 
    memcpy(&cmd_packet.data[0], &cmd_ping[0], cmd_packet.data_length); 

    soap_init1(&soap, SOAP_XML_INDENT); 

    soap_call_ns__send_command(&soap, "http://10.0.0.10:2012", "", cmd_packet, &resp_packet); 
    if (soap.error) 
    { 
     soap_print_fault(&soap, stderr); 
     exit(1); 
    } 
    else 
    { 
     int j; 
     printf("Command Data, length = %d\n", cmd_packet.data_length); 
     for(j = 0; j < cmd_packet.data_length; j++) 
      printf("%02X ", cmd_packet.data[j]); 
     printf("\n"); 
     printf("Response Data, length = %d\n", resp_packet.data_length); 
     for(j = 0; j < resp_packet.data_length; j++) 
      printf("%02X ", resp_packet.data[j]); 
     printf("\n"); 
    } 

    soap_destroy(&soap); 
    soap_end(&soap); 
    soap_done(&soap); 
    return 0;  
}

从客户端输出

Command Data, length = 16 
56 69 56 4F 70 61 79 56 33 00 18 01 00 00 04 7E 
Response Data, length = 16 
56 00 DE C0 F4 C8 45 09 04 00 00 00 F9 06 02 00
