I'm trying to read data from a text file and join it with a post string. When there's only one line in the file, it works fine. But with 2 lines, my request is failed. Is each_line reading the line break? How can I correct it?
File.open('sfzh.txt','r'){|f|
f.each_line{|row|
send(row)
}
I did bypass this issue with split and extra delimiter. But it just looks ugly.

Overview. The IO instance is the basis for all input and output operations in Ruby. Using this instance, we can read a file and get its contents line by line using the foreach() method. This method takes the name of the file, and then a block which gives us access to each line of the contents of the file.
\r\n should probably do the trick.
Use File#readlines to Read Lines of a File in Ruby File#readlines takes a filename to read and returns an array of lines. Newline character \n may be included in each line. We must be cautious when working with a large file, File#readlines will read all lines at once and load them into memory.
\n is the newline character. It prints a new line.
Yes, each_line includes line breaks. But you can strip them easily using chomp:
File.foreach('test1.rb') do |line|
send line.chomp
end
