gSoap-从客户端应用程序httpgettest.c中的响应解析自定义http标头

问题描述

gsoap-master拥有httpgettest.c文件来测试http获取请求并打印响应数据。

我想在同一应用程序中打印响应标头的特定键值。

我已搜索并找到以下解决方案 gSoap - parse custom http header from request

但是它不起作用。下面是修改后的代码

#include "soapH.h"
#include "httpget.h"

int my_parsehdr(struct soap *soap,const char *key,const char *val);

int main(int argc,char **argv)
{ struct soap soap;
  char *body;
  if (argc < 2)
  { fprintf(stderr,"Usage: httpgettest URL\n");
    exit(0);
  }
  soap_init(&soap);
  soap_register_plugin(&soap,http_get); /* register plugin */
  if (soap_http_get_connect(&soap,argv[1],NULL)
   || soap_begin_recv(&soap))
  { soap_print_fault(&soap,stderr);
    exit(1);
  }
  if (soap.http_content)
    printf("HTTP Content Type: %s\n",soap.http_content);
  body = soap_http_get_body(&soap,NULL);
  soap_end_recv(&soap);

  if (body)
    printf("HTTP Body:\n%s\n",body);

  soap.user = (void*)soap.fparsehdr; // to call fparsehdr() in our callback
  soap.fparsehdr = my_parsehdr;

  char *key = "Host";
  char *value = "";
  int return_val = soap.fparsehdr(&soap,key,value);
  printf("HTTP fparsehdr return val: %d \n",return_val);
  printf("HTTP header Key:%s\n",key);
  printf("HTTP header value:%s\n",value);
  
  soap_end(&soap);
  soap_done(&soap);
  return 0;
}

SOAP_NMAC struct Namespace namespaces[] =
{
    {NULL,NULL,NULL}
};

typedef int(*PARSEFUNC)(struct soap*,const char*,const char*);
int my_parsehdr(struct soap *soap,const char *val)
{
  printf ("\n\n Inside call back \n\n");
  // check key (non-NULL) and use val (non-NULL)
  return ((PARSEFUNC)(soap->user))(soap,val);
}

这里我使用了fparsehdr回调函数来解析标题键
