在LoadRunner中转换字符串大小写的C语言函数

封装ConvertToXXX函数：

//ConvertToUpper function

int ConvertToUpper(char * sInput, char * sNew)

{

sInput = (char *)strupr(sInput);

lr_save_string(sInput,sNew);

}

//ConvertToLower function

int ConvertToLower(char * sInput, char * sNew)

{

sInput = (char *)strlwr(sInput);

lr_save_string(sInput,sNew);

}

//ConvertToTitle function

int ConvertToTitle(char * sInput, char * sNew)

{

int i = 0, s = 0, l = 0;

char buf1[50];

char buf2[2];

char n;

// Copy a single character into the address of [n]

strncpy(&n,sInput+i,1);

// Copy the single character into buf2

sprintf(buf2,"%c",n);

// Convert the contents of buf2 to uppercase

strupr(buf2);

// Overwrite the contents of buf1 with buf2

strcpy(buf1,buf2);

i++;

while(i < strlen(sInput))

{

// Overwrite buf2 with one character

strncpy(&n,sInput+i,1);

sprintf(buf2,"%c",n);

// If the previous character was a space then make the current character upper case

if(s == 1){

strupr(buf2);

strcat(buf1,buf2);

s = 0;

}

// Otherwise convert to lower case and concatenate the current character into the string buf1

else{

strlwr(buf2);

strcat(buf1,buf2);

}

// If the current character is a space set the value of [s] to [1] so that the next character gets capitalised

if(strcmp(" ",buf2)==0)

{

s = 1;

}

i++;

}

lr_save_string(buf1,sNew);

}

使用ConvertToXXX转换函数：

Action()

{

lr_save_string("testing is believing","str");

ConvertToUpper(lr_eval_string("{str}"),"UpperStr");

lr_output_message(lr_eval_string("{UpperStr}"));

ConvertToLower(lr_eval_string("{str}"),"LowerStr");

lr_output_message(lr_eval_string("{LowerStr}"));

ConvertToTitle(lr_eval_string("{str}"),"TitleStr");

lr_output_message(lr_eval_string("{TitleStr}"));

return 0;

}

输出：
