  • LoadRunner字符串处理

    有些时候需要在某个字符串的前面用0补齐,以便满足长度的格式要求。

    在LoadRunner中可以封装出一个函数来处理这种问题:

    /*

    Function to pad a string to x characters adding the required character at the start of the string

    (Note string length limited by length of the array)

    Author: Steven Woodcock, Sopra Group

    Inputs:

    strCharToPad - The String that requires to be padded out i.e. "123456"

    cParamName - The name of the parameter you want the end value to be saved to

    iValLength - The length you want the string to be padded out to i.e. 9

    cValueToAdd - The character you want to pad the string out with, must be a single character i.e. "0"

    Outputs:

    Creates a LoadRunner parameter of a name specified in the input 'cParamName'

    */

    int lr_padstr(char* cCharToPad, char* cParamName, int iValLength, char* cValueToAdd){

           char cTemp[1024] = "";

           int iLoop = 0;

           int iMainLoop = 0;

           int iSubLoop = 0;

           for(iMainLoop = 0; iMainLoop < iValLength; iMainLoop++){

                  if (iMainLoop == strlen(cCharToPad)) {

                         iLoop = iValLength - iMainLoop;

                         for (iSubLoop = 0; iSubLoop < iLoop; iSubLoop++) {

                                strcat(cTemp, cValueToAdd);

                         }

                  }

                 

           }

           strcat(cTemp, cCharToPad);

           lr_save_string(cTemp, cParamName);

    }

    lr_padstr可以在指定字符串前补齐指定长度的某个字符,然后把修改后的字符串存入LoadRunner参数中。把以上代码放到lr_padstr.h头文件中,在LoadRunner脚本中引用:

    #include "lr_padstr.h"

    Action()

    {

           //     For the lr_padstr function

                  char * cShortValue = "123";

           //     For the sprintf function

                  char cPaddedValue[8] ="";

                  int iShortValue = 123;

                  int i;

           //     The lr_padstr function, written by Steven Woodcock can be used to pad with zeroes

                  lr_padstr(cShortValue,"pPaddedParameter",8,"0");

                  lr_output_message("Padded value is %s", lr_eval_string("{pPaddedParameter}"));

           //     The PadToX function can also be used to pad with other characters (e.g. x)

                  lr_padstr(cShortValue,"pPaddedParameter",8,"x");

                  lr_output_message("Padded value is %s", lr_eval_string("{pPaddedParameter}"));

           return 0;

    }
