How to convert special characters of an url in cakephp3? - url

I have an upload folder in webroot that contains my pictures. And I read picture path from database.
picture->path = 'uploads\pictures\pic1.png'
When I try to show pictures with line below
echo $this->Html->image('/'.$picture->path);
browser could not show pictures. This is the result html that generated with cakephp
<img src="/projects/bookmarker/uploads%5Cpictures%5Cpic1.png" alt="">
I think special characters such as %5C caused this problem.

Replace
picture->path = 'uploads\pictures\pic1.png'
with
picture->path -- 'uploads/pictures/pic1.png'
The above can be achieved with str_replace() in php.

Is there a script that can extract particular link from txt and write it in another txt file?

I'm looking for a script (or if there isn't, I guess I'll have to write my own).
I wanted to ask if anyone here knows a script that can take a txt file with n links (lets say 200). I need to extract only links that have particular characters in them, let's say I only need links that contain "/r/learnprogramming". I need the script to get those links and write them to another txt files.
Edit: Here is what helped me: grep -i "/r/learnprogramming" 1.txt >2.txt
you can use ajax to read .txt file using jquery
<script src=https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js></script>
<script>
jQuery(function($) {
console.log("start")
$.get("https://ayulayol.imfast.io/ajaxads/ajaxads.txt", function(wholeTextFile) {
var lines = wholeTextFile.split(/\n/),
randomIndex = Math.floor(Math.random() * lines.length),
randomLine = lines[randomIndex];
console.log(randomIndex, randomLine)
$("#ajax").html(randomLine.replace(/#/g,"<br>"))
})
})
</script>
<div id=ajax></div>
If you are using linux or macOS you could use cat and grep to output the links.
cat in.txt | grep /r/programming > out.txt
Solution provided by OP:
grep -i "/r/learnprogramming" 1.txt >2.txt
Since you did not provide the exact format of the document I assume those links are separated by newline characters. In this case, the code is pretty straightforward using Python/awk since you can iterate over file.readlines() and print only those that match your pattern (either by using a lines.contains(pattern) or using a regex if the pattern is more complex). To store the links in a new file simply redirect the stdout to a new file like this:
python script.py > links.txt
The solution above works even if links are separated by an arbitrary symbol s, first read the file into a single string and split it over s. I hope this helps.

Problem with attachments' character encoding using gmail gem in ruby/rails

What I am doing:
I am using the gmail gem in a Rails 4 app to get email attachments from a specific account at regular intervals. Here is an extract from the core part (here for simplicity only considering the first email and its first attachment):
require 'gmail'
Gmail.connect(#user_email,#user_password) do |gmail|
if gmail.logged_in?
emails = gmail.inbox.emails(:from => #sender_email)
email = emails[0]
attachment = email.message.attachments[0]
File.open("~/temp.csv", 'w') do |file|
file.write(
StringIO.new(attachment.decoded.to_s[2..-2].force_encoding("ISO-8859-15").encode!('UTF-8')).read
)
end
end
end
The encoding of the attached file can vary. The particular one that I am currently having issues with is in Finnish. It contains Finnish characters and a superscripted 3 character.
This is what I expect to get when I run the above code. (This is what I get when I download the attachment manually through gmail user interface):
What the problem is:
However, I am getting the following odd results.
From cat temp.csv (Looks good to me):
With nano temp.csv (Here I have no idea what I am looking at):
This is what temp.csv looks like opened in Sublime Text (directly via winscp). First line and small parts look ok but then Chinese/Japanese characters:
This is what temp.csv looks like in Notepad (after download via winscp). Looks ok except a blank space has been inserted between each character and the new lines seems to be missing:
What I have tried:
I have without success tried:
.force_encoding(...) with all the different "ISO-8859-x" character sets
putting the force_encoding("ISO-8859-15").encode!('UTF-8') outside the .read (works but doesn't solve the problem)
encode to UTF-8 without first forcing another encoding but this leads to Encoding::UndefinedConversionError: "\xC4" from ASCII-8BIT to UTF-8
writing as binary with 'wb' and 'w+b' in the File.open() (which oddly doesn't seem to make a difference to the outcome).
searching stackoverflow and the web for other ideas.
Any ideas would be much appreciated!
Not beautiful, but it will work for me now.
After re-encoding, I convert the string to a char array, then remove the chars I do not want and then join the remaining array elements to form a string.
decoded_att = attachment.decoded
data = decoded_att.encode("UTF-8", "ISO-8859-1", invalid: :replace, undef: :replace).gsub("\r\n", "\n")
data_as_array = data.chars
data_as_array = data_as_array.delete_if {|i| i == "\u0000" || i == "ÿ" || i == "þ"}
data = data_as_array.join('').to_s
File.write("~/temp.csv", data.to_s)
This will work for me now. However, I have no idea how these characters have ended up in the attachment ("ÿ" and "þ" in the start of the document and "\u0000" between all remaining characters).
It seems like you need to do attachment.body.decoded instead of attachment.decoded

PHPEXCEL weird characters on form inputs

I need some help with PHPEXCEL library, everything works great, I'm successfully extracting my SQL query to excel5 file, I need to give this file to transport company in order to auto collect informations about packages, unfotunately the generated excel file has some ascii characters between each letter of the cell text, and when the excel file is imported you need to manually delete these charaters.
If I open the excel file, everything is fine I see: COMPANY NAME, If I open the excel file with notepad++, I see the cell values this way: C(NUL)O(NUL)M(NUL)P(NUL)A(NUL)N(NUL)Y N(NUL)A(NUL)M(NUL)E
If I open again the file with excel and save, then reopen with notepad++ I see COMPANY NAME.
So I do not understan why every time I create an excel file using PHPEXCEL my every letter of all words are filled with (nul) every letter.
So how do I prevent the generated excel file to include (nul) between every word????
Also if you open the original excel file generated from PHPExcel samples are also filled with (nul) and if you open and save it, the (nul) is gone.
Any help would be appreciated, thanks.
what is the (nul) ??? 0x00??? char(0)???
ok, here is the example:
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');
if (PHP_SAPI == 'cli')
die('Disponibile solo su browser');
require_once dirname(__FILE__) . '/Classes/PHPExcel.php';
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("Solidus")
->setLastModifiedBy("Solidus")
->setTitle("Import web")
->setSubject("Import File")
->setDescription("n.a")
->setKeywords("n.a")
->setCategory("n.a");
$objPHPExcel->setActiveSheetIndex(0)
->setCellValueExplicit("A1", "COMPANY")
->setCellValue('A2', 'SAMSUNG');
$objPHPExcel->getActiveSheet()->setTitle('DDT');
$objPHPExcel->setActiveSheetIndex(0);
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="TEST.xls"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
header('Cache-Control: private',false);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
ob_end_clean();
$objWriter->save('php://output');
As you can see from this little example, this scripts creates a file excel5 with 2 cells, A1 = COMPANY, A2 = SAMSUNG
when I send this file to the transport company, they import the file into their system, but as you can see from the picture, there is an weird character between each letter.
so I noticed every time I open the generated Excel5 with notepad++ file I get:
S(nul)A(nul)M(nul)S(nul)U(nul)N(nul)G
If I save the save with excel and then open it again with notepad++ I get:
SAMSUNG
and this file is ok for the transport company
so my question is, how should I avoid the file generated to contain thi '(nul) charachter between each letter????
some help?
weird characters
SAMSUNG
I found the soluion by myself, I explain just in case anyone has also this problem:
there is not way to change the way the excelfile is encoded by PHPEXCEL
so I figured out the problem was reading the file, I did some simulations and reproduce the problem, every time a read the file and put the result into inputs a get weird characters:
C�O�M�P�A�N�Y�
If I set the output enconding enconding as follows:
$excel->setOutputEncoding('UTF-8');
the file loads fine, so the problem was not creating the excel file, but reading the excel file.
If I print the variable with ECHO I get: "COMPANY",
if I put the variable on input as value I get: "C�O�M�P�A�N�Y�"
setting the output solves the problem, but I would like to know why the difference when I put the variable on input as value, thanks

SSRS Goto URL decoding and encoding

I am facing problem when passing value for url through data field.
I am passing value in goto url like this
="javascript:void(window.open('file:" &Fields!url.Value &"','_blank'))"
url value = /servername/foldername/FormuláriodeCalibração.xls
After report deployed and opened in internet explorer and clicked on the url. It is changing the url like this
/servername/foldername/FormuláriodeCalibração.xls
because of which I am unable to open the file.
Please help me in this.
Finally we come up with a solution of replacing non ASCII characters of Portuguese with HTML ASCII Codes.
For e.g. this is the actual file name of the attachment
TE-5180FormuláriodeCalibração(modelo)1271440308393(2)1338379011084.xls
We replaced the Portuguese characters with HTML ASCII Codes.
TE-5180FormuláriodeCalibração(modelo)1271440308393(2)1338379011084.xls
After these changes the above modified URL is passed in the place of actual URL and when it hits the server it was decoded properly and worked as expected.

Get the filepath of an image inserted into TWebBrowser in edit mode

When you insert an image into a TWebBrowser in edit mode, how do you get the filepath of the inserted image? When an image is inserted it includes the full path to the image in the html source, but in my case I need to modify the html source to only include the filename.
EDIT:
This is the html source after the image is inserted:
<IMG border=0 hspace=0 alt=delphi align=baseline
src="C:\Images\delphi.bmp">
I need to change
<IMG border=0 hspace=0 alt=delphi align=baseline
src="C:\Images\delphi.bmp">
to
<IMG border=0 hspace=0 alt=delphi align=baseline
src="HTML\delphi.bmp">
Yes I can get the path from the html but I'd like to try to copy the image file to the HTML folder then change the path to the HTML folder after the image is inserted without parsing the html. If the filepath can be obtained after the image is inserted I can add the code to copy the file to the HTML folder so that the image appears in the webbrowser with the new path...
Have you tried using the browser's DOM interfaces to read the src attribute and update it to what you want? Specifically, look at the src property of the IHTMLImgElement interface.
