Pavan Kumar Pyneni,

The last output shown is correct JSON and the expected output not. JSON is a nested data structure and each member like "RequestBody" can have a single value like a string, or number etc, but also a List (something between [ ] ) or even an Structure (or Dict) with members between { }.

It you like to add to a JSON member a string, you need to escape each inner " with \ and might replace each newline with \n.

So this is also OK (I left out the new lines):

"RequestBody": "{\"Test\": null,\"Value\": 9878,\"Date\": null}"

To get the last value in RequestBody your have to escape each " in the result of lr_eval_string("{response}") before assigning it to parameter tmp.

I think also that you need quotes around the {tmp} in:

               "Value=\"{tmp}\"",

or make a json-stringify function that does all the work. E.g.

 // evaluate and stringify a json_param and puts it
 // as a string constant in param.
 void my_json_stringify(char *json_param, char *param)
 {
     char *p, *q;
     char *buf = (char*)malloc(strlen(json_param)+10);
     sprintf(buf,"Buffer={%s}", json_param);
     lr_eval_json(buf, "JsonObject=MY_MJO",LAST);
     free(buf);
     lr_json_stringify("JsonObject=MY_MJO","Format=compact", "OutputParam=my_json_stringify_param",LAST);
     p = lr_eval_string("{my_json_stringify_param}");
     buf = q = (char*)malloc(strlen(p)*2+2);
     *q++ = '"';                       // Start quote
     while(*p) {
         if( *p == '"' ) *q++ = '\\';  // Escape "
         *q++ = *p++;                  // Copy character
     }
     *q++ = '"';                       // End quote
     *q   = '\0';                      // End of String
     lr_save_string(buf, param);
     free(buf);
 }


// Example:
  lr_save_string("{\"Test\": null,\n\"Value\": 9878,\n\"Date\": null\n}", "ResponseBody");
  my_json_stringify("ResponseBody", "response2");
  lr_log_message(lr_eval_string("{response2}"));
// Log: "{\"Test\":null,\"Value\":9878,\"Date\":null}"

constant

Thank you for the idea. I used the below code to replace " with /".

char *string_replace(char *input_string,
    char *substring_to_be_replaced,
    char *substitution_string)

 {

// strstr function declaration
 char *strstr(const char *s1, const char *s2); 

// newstring variable the new string to be returned
// increase the buffer size if needed. Default is 200

char newstring[200]=""; 

// str is a temporary pointer to aid in creation of newstring;
// it points at the beginning of each substring that
// needs to be included in the new string.

char *str; 

// ptr is a pointer to hold strstr result.

char *ptr; 

str = input_string;

// search for substring_to_be_replaced and
// replace with substitution_string

 while((ptr = strstr(input_string, substring_to_be_replaced))!=NULL)
 {
 input_string = &ptr[strlen(substring_to_be_replaced)];
 ptr[0] = '\0';
 strcat(newstring, str);
 strcat(newstring, substitution_string);
 str = input_string;
 }

// concatenate the rest of the string

strcat(newstring, input_string);

return newstring;

 }
