Re: How to send array of parameters in web_submit_form ? - Micro Focus Community

agks7 · ‎2019-11-27

Hi!

I collect all INPUT TEXT on the page and write the value "test".

I have a code:

web_reg_save_param_attrib(
        "ParamName=inputTexts",
        "TagName=INPUT",
        "Extract=NAME",
        "Type=TEXT",
        "NotFound=warning",
        "Ordinal=ALL",
        SEARCH_FILTERS,
        "IgnoreRedirections=Yes",
        LAST);

    web_link("Start",
        "Text=Start",
        "Snapshot=t56.inf",
        LAST);

web_submit_form("1",
        "Snapshot=t57.inf",
        ITEMDATA,
        "Name={inputTexts}", "Value=test", ENDITEM, //Array in this place
        LAST);

It should look something like this.

web_submit_form("1",
        "Snapshot=t57.inf",
        ITEMDATA,
        "Name={inputTexts_1}", "Value=test", ENDITEM,

"Name={inputTexts_2}", "Value=test", ENDITEM,

.........................

"Name={inputTexts_count}", "Value=test", ENDITEM,

LAST);

But the data is dynamic.

I don't know how to do it here. The loop between ITEMDATA and LAST doesn't work or I don't understand something. Please help!

Firstly try changing in recording options General > Recording> HTML Advanced: A script containing explicit URLs only AND Record in separate steps & use concurrent groups. This will give complete arguments of web_submit_data()

If I understand correctly, you have the different number of ITEMDATA based on the previous request response. Try using text check and if condition based on the previous request response. For example:

   web_reg_find("Text=TEXTCHECK", "SaveCount=cCheckCount1", "Search=Body", LAST);

    web_link("Start",
        "Action=https://{URL}",
        "Method=POST",
        "Text=Start",
        "Snapshot=t56.inf",
        LAST);

if(atoi(lr_eval_string("{cCheckCount1}"))!=0)
    {
    web_submit_form("1",
        "Snapshot=t57.inf",
        ITEMDATA,
        "Name={inputTexts1}", "Value=test", ENDITEM, //Array in this place
        LAST);

     }
    else{
    web_submit_form("1",
        "Snapshot=t57.inf",
        ITEMDATA,
        "Name={inputTexts1}", "Value=test", ENDITEM, //Array in this place
        "Name={inputTexts2}", "Value=test", ENDITEM, //Array in this place
        LAST);

}

@agks7, I sketched here already an approach. But lets make it here a little more clear with some example code:

#include "stdlib.h"
#include "string.h"

#define LR_VARARGS_MAX 100
typedef struct { char *a[LR_VARARGS_MAX]; } t_lr_varargs;
t_lr_varargs f_args;
int f_i=0;

#define f_args_add(X) f_args.a[f_i++] = X

// Maintain a list of malloced arguments like: "Name={inputTexts_%d}"
char *f_args_param_list[LR_VARARGS_MAX];
int f_args_param_idx = 0;
void f_args_add_paramarr(char *pattern, int i) {
	char *p = (char*)malloc(strlen(pattern)+2+1); // For one number upto 2 digits.
	sprintf(p, pattern, i);
	f_args_param_list[f_args_param_idx++] = p;
	f_args_add(p);
}
void f_args_reset() {
	int i;
	for(i=0; i<f_args_param_idx; i++ ) {
		if( f_args_param_list[i] ) {
			free( f_args_param_list[i] );
			f_args_param_list[i] = NULL;
		}
	}
	f_args_param_idx = 0;
	f_i = 0;
}
Action()
{
int i,c;
// Parameter collection code goes here.
. . .
// web_submit_form("1", <== Move this to below argument build code.
        f_args_add("Snapshot=t57.inf");
        f_args_add(ITEMDATA);
        c = lr_paramarr_len("inputTexts");
        for(i=1; i<=c; i++ ) {
                f_args_add_paramarr("Name={inputTexts_%d}", i);
                f_args_add("Value=test");
                f_args_add(ENDITEM);
        } 
        f_args_add(LAST);
web_submit_form("1", f_args); // <== Always keep to any LR-function first argument with var-args.
f_args_reset();

I did not test this in all details. But with this approach you should be able to resolve this.

Note: no check on going beyond LR_VARARGS_MAX etc.

Have fun.

I'm testing the script only on the INPUT TEXT. When there is only INPUT TEXT on the page, without RADIO and SELECT , the script should work. But there is ERROR (Error -27153: Either "Name" or at least one of "NamePfx" and "NameSfx" should be non-empty (before the "ENDITEM" argument number 5). I do not understand. Empty NAME can be due to the fact that more values are sent than there are fields for text input. Or what? I'm stupid. Help me pls. I am beginner

JHF Remmelzwaal · ‎2019-11-27

@agks7, please study the editor for posting (pressing icon with 3 dots shows you the icon to enter code in a readable way).

Even when you are a beginner you can build your own 'debug' code. Here is an example that you might use:

void f_args_debug()
{
	int i;
	for(i=0; i<f_i; i++ ) {
		lr_log_message("%2d, '%s' => '%s'", i, f_args.a[i], lr_eval_string(f_args.a[i]));
	}
}

Call the function just before the lr_submit_form. It will show all the arguments, you will see that "Name=..." argument is missing.

The very first post contained an error that I corrected by editing my post in 5 min after initial post. You where just too quick. Your function 'f_args_add_param' should just contain one more statement.

Excuse for this inconvenience.

P.S.

"I'm stupid. Help me pls. I am beginner", I think that you are right: It is stupid as a beginner to think that you are stupid that you cannot resolve an issue in advanced code, you did not write 😉

@JHF Remmelzwaal

Thank you very much for your help. It's a huge help in speeding up my learning. I have another question. In the version with Truclient I wrote a script with JavaScript. The code processed and filled INPUT TEXT, RADIO and SELECT. Is it possible to integrate this code into Action.c ? To work with the document.getElementsBy...Like there is a "web_js_run", but I don't know how to link it.

JavaScript code:

//******INPUT TEXT
//Create array of all inputs on the page
var inputArray = document.getElementsByTagName("input");

//Find all input text fields and fill it by value "test"
for (var t=0;t<inputArray.length;t++)
{
  if (inputArray[t].type=="text")
    inputArray[t].value="test";
}


//*******INPUT RADIO
//Create set for radiogroup names
let set = new Set();

//Create array of all inputs on the page
var radioArray = document.getElementsByTagName("input");

//Add radiogroup names in set
for (var t=0;t<radioArray.length;t++)
{
  if (radioArray[t].type=="radio")
    set.add(radioArray[t].name);
}

//Outside loop for enum names of radiogroup
set.forEach((value, valueAgain, set) => {
 
  var rad=document.getElementsByName(value); //create array for values in radiogroup 
  
  //Inside loop for enum values in each radiogroup and Find value with maximal length
  for (var i=1, max=rad[0].value, maxi=0;i<rad.length; i++) {
        
     	//Compare nearby values
    	if (rad[i].value.length>max.length)
          {
            max=rad[i].value; //max length value
            maxi=i; //index of max length value
            
          }
        }
        rad[maxi].checked=true;//check max length value if radiogroup
}
      			)
//******SELECTS     
//Create set for "select" names
let set = new Set();

//Create array of all "select" on the page
var radioArray = document.getElementsByTagName("select");

//Add "select" names in set
for (var t=0;t<radioArray.length;t++)
{
      set.add(radioArray[t].name);
}

//Outside loop for enum names of "select"
set.forEach((value, valueAgain, set) => {
  
	//One of "Select"
  var rad=document.getElementsByName(value);

	//Inside loop for enum values in each "select" and Find value with maximal length
  for (var i=1, max="", maxi=0;i<rad[0].options.length; i++) {
        if (rad[0].options[i].value.length>max.length)
          {
            max=rad[0].options[i].value; //max length value
            maxi=i; //index of max length value
          }
        }
        rad[0].value = max;//set max length value if "select"
	}
    			)

The answer is simple NO. Understanding why is important. TruClient works on an head-less browser (so has access to the DOM). Web protocol works on the network so there is no internal representation of the DOM.

You can use "web_js_run" to execute some java script code if you like, but hard to use.

You might describe in words your approach (algorithm). I cannot see your intention.

But you might make one wrong assumption and that is related to LR parameter expansion.

Read carefully the LR help on the functions: lt_eval_string and lr_paramarr_idx.

Use logging function like:

lr_log_message("Compare string '%s' with '%s' gives %d", names_i, names_i1, strcmp(names_i,names_i1));

You will find what is going wrong.
