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;
}

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}"));
