I am trying to make a sms notification using nexmo. I dont know what it means Too few arguments to function Vonage\Client::Vonage{closure}(), 4 passed and exactly 5 expected. I was trying to search for the error and it said the error is in line 145 from folder vendor\nexmo\client-core\src\Client.php on line 145enter image description here
I have an api that returns 50 users.
Is there a way of looping through the api call
expand=users%5B1%3A50%5D
The 1 after B is the starting number and it will pull until 50 which is the number after A
I have a script that will store the responses to a text file but how can I loop through this adding increments of 50?
For example. having a variable in place of the numbers
expand=users%5B$num1%3A$num2%5D
expand=users%5B{1..50}%3A50%5D
The {1..5} will expand as 1 2 3 4 5
for example
$ echo abc{1..5}def
abc1def abc2def abc3def abc4def abc5def
now all you need is to loop over the expand
for api in $expand
do
#do something
done
I'm currently working on a Bash script that simulates rolling a number of 6-sided dice. This is all taking place within a virtual machine running Debian that's acting as a server. Essentially, my webpage simulates rolling the dice by using the query string to determing the number of dice to be rolled.
For instance, if my URL is http://127.0.0.1/cgi-bin/rolldice.sh?6, I want the webpage to say "You rolled 6 dice" and then, on the next line, print six numbers between 1 and 6 inclusive (that are of course "randomly" generated).
Currently, printing out the "You rolled x dice" header is working fine. However, I'm having trouble with the next part. I'm very new to Bash, so possibly the syntax or something similar is wrong with my loop. Here it is:
for i in {1..$QUERY_STRING }; do
dieRoll = $(( $RANDOM % 6 + 1))
echo $dieRoll
done
Can anyone help me figure out where I'm going wrong? I'll be happy to post the rest of rolldice.sh if needed.
Since .. requires its arguments to be literals, you have to use eval to substitute the variable:
for i in $(eval "echo {1..$QUERY_STRING}"); do
Or if you have the seq command, you can do:
for i in $(seq 1 "$QUERY_STRING")
I recommend the latter -- using eval with input from the user is very dangerous.
This program puzzles me. The goal of this program is to count the number of newlines in a file and output it in command prompt. Learnyounode then runs their own check on the file and sees if their answer matches your answer.
So I start with the answer :
var fs = require('fs');
var filename = process.argv[2];
file = fs.readFileSync(filename);
contents = file.toString();
console.log(contents.split('\n').length - 1);
learnyounode verifies that this program correctly counts the number of new lines. But when I change the program to any of the following, it doesn't print out the same number as learnyounode prints out.
file = fs.readFileSync(C:/Nick/test.txt);
file = fs.readFileSync(test.txt);
Shouldn't nodejs readFileSync be able to input an address and read it correctly?
Lastly, this program is supposed to print out the # of newlines in a program. Why does both the correct program and learnyounode print out the same number that is different from the amount of newlines everytime I run this program?
For example, the number of newlines in test.txt is 3. But running this program prints out a different number everytime, like 45, 15, 2, etc. Yet at the same time, it is verified as a correct program by learnyounode because both their answers match! What is going on?
EDIT:
test.txt looks like this
ok
testing
123
So, I tried your program on my local machine and your program works fine. I am not an expert on learnyounode. I just tried it after your question but I think I understand how it works. As such, here are the answers to your questions:
Shouldn't nodejs readFileSync be able to input an address and read it correctly?
This method from nodejs is working fine. You can try printing the contents of the file and you'll see that there are no problems.
Why does both the correct program and learnyounode print out the same number that is different from the amount of newlines everytime I run this program.
learnyounode is running your program with a different filename as input each time. It verifies the output of your program by running its own copy of correct code against the same file.
But when I change the program to any of the following, it doesn't print out the same number as learnyounode prints out.
That is because at this point, your code is processing a fixed file whereas learnyounode is still processing different files on each iteration.
This tripped me up too. If you read the learnyounode instructions closely they explicitly say...
"The full path to the file to read will be provided as the first command-line argument."
This means they are providing the path to their own file.
When you use process.argv[2], this is passing in the 3rd array item (the learnyounode test txt file) into your script. If you run a console.log(process.argv); you'll see the full array object looks something like this:
[ '/usr/local/bin/node',
'/Users/user/pathstuff/learnyounode/firstio.js',
'/var/folders/41/p2jvc80j26l7nty0sk0zs1z40000gn/T/_learnyounode_1613.txt' ]
The reason the validation numbers begin to mismatch when you substitute your own text file for their is because your file always has 3 lines whereas their unit tests keep passing in different length files via process.argv.
Hope that helps.
when you are using process.argv[2] in learnyounode, the argument is provided by learnyounode automatically, so it prints different number of lines like 45, 15, 2 etc at multiple times verification.
If you remember the second challenge "BABYSTEPS" carefully this was given:
learnyounode will be supplying arguments to your program when you run
learnyounode verify program.js so you don't need to supply them yourself.
That's why different line numbers at program.js verification on multiple times.
there are two different ways.
if you run program like:
node program_name.js
than you need to add path to text file:
node program_name.js text_file.txt
in this case make sure that files are in the same directory.
or you can run it with command:
learnyounode program_name.js
and than default text file will be provided by learnyounode. You can watch content of this text file by using
console.log(buffer)
Problem statement says
The full path to the file to read will be provided as the first
command-line argument.
So you've to pass the path/to/file as an argument.
Remember process.argv
you should use the following method to execute .js files
node program_name.js /path/to/text_file_name
rather than
learnyounode run program_name.js /path/to/text_file_name
on this method, Node.js will run your program with specify files of you enter on the command-line-interface.
wish this answer can help you programming. :)
I want to use expect_out to get the output for the last send
for the following snippet
while {[gets $cmds command]>=0} {
send "$command\r"
expect "*"
set result $expect_out(buffer)
puts $gout $result
}
but expect_out(buffer) seems to maintain all previous outputs
how can I achieve my goal? thanks
Untested, but try adding another expect * before sending the command.
When in doubt while developing an expect program, add exp_internal 1 to the top of your script.
