how to pass a variable through a url


By : Maximillian Wells
Date : October 18 2020, 06:10 PM
wish helps you You are setting the variable in the url correctly. Now you just have to grab it. When you visit a webpage, you are using a GET request, so these "url variables" can be grabbed through the $_GET array.
All you have to do to accomplish this is do something like this:
code :
$myvar = $_GET['ws-id'];

How to pass a bash variable to sqlplus and then pass that output to another variable


By : Aleksey Lyashin
Date : March 29 2020, 07:55 AM
will be helpful for those in need So what I'm trying to do is to clear the audit logs of the PDB in an Oracle database. The name of the PDB can be different each time, so I cannot use tnsnames to sqlplus directly into the PDB to do this. I'm passing commands into bash and then passing those into a SQLPLUS command. Each of these work except for one and I can't seem to figure out how to get it to work. ,
The error I keep getting is
code :
alter session set container=select pdb_name from dba_pdbs where pdb_name != 'PDB$SEED';
                            *
ERROR at line 1:
ORA-65015: missing or invalid container name
alter session set container=select pdb_name from dba_pdbs where pdb_name != 'PDB$SEED';
sqlplus -S /nolog <<"EOF1"
  connect / as sysdba
  set echo off feedback off head off pages 0
  set serveroutput on
  column pdb_name new_value pdb
  select pdb_name from dba_pdbs where pdb_name != 'PDB\$SEED';
  alter session set container = &pdb.;
  delete from sys.aud$ where ntimestamp# < sysdate - 30;
  exit;
EOF1

Pass an output of stdout(jmeter) and pass it as variable string to another sampler

I wish this helpful for you This is my scenario I'm running a java program in bean shell sampler in j meter and getting the required string in STD OUT console. Even i have successfully wrote the required string to a output file. I need to extract the string from the file or console and pass it to other samples(the required string is present along with lot of information in the output so i need to extract string like "Required String:following Character" in advance , When ever You need to direct a output Use this following code
code :
System.setOut(new PrintStream(new BufferedOutputStream(new
FileOutputStream("path/to/file/output.txt")), true));
import userdir.UserClass;

UserClass obj1 =new UserClass(); obj1.method1();

System.setOut(new PrintStream(new BufferedOutputStream(new
FileOutputStream("path/to/file/output.txt")), true));
import java.io.FileNotFoundException;   
import java.util.Scanner;   
import org.apache.jmeter.samplers.SampleResult;

File file = new File("path/to/file/output.txt");  
String word = "Req String1";  
String word2 = "Req String2";  
Scanner scanner = null;  
String line;   
String s1;  
String s2;     
try {
   scanner = new Scanner(file); }    
  catch(FileNotFoundException e) {     //handle this }

 //now read the file line by line     

 while (scanner.hasNextLine()) {  
line = scanner.nextLine();

if(line.contains(word)) {   
   log.info(line);  
   s1=line;    
  //now the entire line along with Req String1 will be stored in s1
}

if(line.contains(word2)) { 
  log.info(line);
   s2=line;
}
 }

log.info("The value in Encrypt str  ="+s1);  
log.info("The value in Signatr str  ="+s2);  
String[] s1 = s1.split(":");  
String[] s2 =s2.split(":");  
//since my value in the line is Req String1:needed data

props.put("s1",s1[1]);  
props.put("s2",s2[1]);

log.info("The value in ORIGINAL Req String1  ="+props.get("s1"));
log.info("The value in ORIGINAL Req String2  ="+props.get("s2"));
scanner.close();

How to pass (rapidly updated) variable from ctypes C code to Python? Pass by reference?

around this issue Although you're familiar with the concepts, here's [Python 3.Docs]: ctypes - A foreign function library for Python.
Python code polling a memory area while the C code is running, implies more than one thread.
code :
#include <stdio.h>
#include <Windows.h>

#if defined(_WIN32)
#  define DLL_EXPORT __declspec(dllexport)
#else
#  define DLL_EXPORT
#endif

#define PRINT_MSG_2XI(ARG0, ARG1) printf("From C - [%s] (%d) - [%s]:  ARG0: 0x%016p, ARG1: %d\n", __FILE__, __LINE__, __FUNCTION__, ARG0, ARG1)


typedef struct Srtruct_ {
    int value;
    int sentinel;
} Struct;


DLL_EXPORT int func0(Struct *ptr) {
    int counter = 0;
    if (!ptr) {
        return -1;
    }
    while (ptr->sentinel) {
        ptr->value++;
        counter++;
        PRINT_MSG_2XI(ptr, ptr->value);
        Sleep(200);
    }
    return counter;
}
#!/usr/bin/env python3

import sys
import ctypes
import time
import threading


DLL_NAME = "./dll.dll"


class Struct(ctypes.Structure):
    _fields_ = [
        ("value", ctypes.c_int),
        ("sentinel", ctypes.c_int),
    ]


def thread_func(func, arg0):
    ret = func(arg0)
    print("\nFrom Python - Function returned {:d}".format(ret))


def main():
    dll = ctypes.CDLL(DLL_NAME)
    func0 = dll.func0
    func0.argtypes = [ctypes.POINTER(Struct)]
    func0.restype = ctypes.c_int

    data = Struct(30, 1)
    t = threading.Thread(target=thread_func, args=(func0, data,))
    t.start()
    time.sleep(1)
    print("From Python - Monitored value: {:d}".format(data.value))
    time.sleep(1)
    print("From Python - Monitored value: {:d}".format(data.value))
    data.sentinel = 0
    time.sleep(0.5)


if __name__ == "__main__":
    print("Python {:s} on {:s}\n".format(sys.version, sys.platform))
    main()
    print("\nDone.")

Why can I pass an integer as a task parameter but can't pass a struct variable?


By : user3555549
Date : March 29 2020, 07:55 AM
will be helpful for those in need The code you show is not taking an int value as a parameter. You pass the parameter using (void*)x, which is an expression that converts the int x to a pointer.
The function xTaskCreate accepts a pointer. You have given it a pointer, so the compiler does not complain. However, the pointer you have given it is not a pointer to x (which would be written as &x) but is a pointer converted from the value of x. Although the compiler does not complain, this is generally not the right thing to pass to xTaskCreate.
