loadrunner中自定义查找并替换函数

globas.h中定义  

//LoadRunner中没有直接的函数支持查找并替换字符串，因此可以封装一个lr_replace函数出来：


// ----------------------------------------------------------------------------
char *strReplace(const char *src, const char *from, const char *to)
{
  char *value;
  char *dst;
  char *match;
  int size;
  int fromlen;
  int tolen;

  size = strlen(src) + 1;
  fromlen = strlen(from);
  tolen = strlen(to);

  
  value = (char *)malloc(size);

  dst = value;


  if ( value != NULL )
  {

    for ( ;; )
    {
     
      match = (char *) strstr(src, from);
      if ( match != NULL )
      {

        size_t count = match - src;


        char *temp;


        size += tolen - fromlen;


        temp = (char *)realloc(value, size);

        if ( temp == NULL )
        {

          free(value);
          return NULL;
        }


        dst = temp + (dst - value);
        value = temp;


        memmove(dst, src, count);
        src += count;
        dst += count;


        memmove(dst, to, tolen);
        src += fromlen;
        dst += tolen;
      }
      else
      {

        strcpy(dst, src);
        break;
      }
    } 
  }
  return value;
}

// ----------------------------------------------------------------------------


// ----------------------------------------------------------------------------
int lr_replace( const char *lrparam, char *findstr, char *replacestr )
{
  int res = 0;
  char *result_str;
  char lrp[1024];


  sprintf( lrp, "{%s}", lrparam);


  result_str = strReplace( lr_eval_string(lrp), findstr, replacestr );


  if (result_str != NULL )
  {
    lr_save_string( result_str, lrparam );
    free( result_str );
    res = 1;
  }
  return res;
}

 

在Action中定义：

login()
{


lr_save_string("This is a string", "MyPar");


//web_convert_param( "MyPar",

//                   "SourceEncoding=PLAIN",
//                   "TargetEncoding=URL", LAST); 


lr_output_message("%s", lr_eval_string("{MyPar}"));


//lr_replace("MyPar", "+", "%20" );


//lr_output_message("%s", lr_eval_string("{MyPar}"));


lr_replace("MyPar", "ing", "旺仔" );   //将Mypar中的ing字符串用旺仔替换


lr_output_message("%s", lr_eval_string("{MyPar}"));
