I want to turn \\\\Network Share\\Folder\\Folder\\File.jpg into a regular path - \\Network Share\Folder\Folder\File.jpg - for a JSON string that I am passing to JavaScript. My code is:
def searchFile(fileName):
for entry in os.scandir(folderToSearch):
if fileName.upper() in entry.path.upper():
if entry.is_file():
return entry.path
Which is returning with the extra backslashes. When I read the JSON data in JavaScript, it cannot find the file due to the extra backslashes. How do I transfer the data from Python to JavaScript?
I am using the eel library.
EDIT
This is how I am creating my JSON data to pass to JavaScript:
def createUserJSON():
UserData = {}
JSONData = []
UserData['fullName'] = "Test User"
UserData['email'] = "Test.User#test.com"
UserData['userImage'] = searchFile("TestUser")
json_data = json.dumps(UserData)
JSONData.append(json_data)
return JSONData
This then returns:
['{"fullName": "Test User", "email": "Test.User#test.com", "userImage": "\\\\Network Share\\Folder\\Folder\\File.jpg"}']
I want to store html code into sql database which I've encoded by using encodeURI() but it showing me multiple errors as below
I'm using dataType as <CLOB> also tried using NVARCHAR(MAX) but is showing same error.
Sharing my encoded html code below in string format tobe store into sql.

Above command i'm using for pushing data to db. QUESTION_DESC string i've encoded.original string is
<p>this kind of text i'm storing into database</p><pre class="code-
pre">var uri = "my test.asp?name=ståle&car=saab";
var enc = encodeURI(uri);
var dec = decodeURI(enc);
var res = enc + "<br>" + dec;
</pre>
Help will be appriciated
This was quite simple when i tried posting html code from middle ware.
The problem is when i tried to post an html code to database it was showing error because of some random double quotes. So while sending that html code from middle ware i just replaced the double quotes to ignore double quotes. i did like
my html code to be stored in db
var htmlCodeToBeStored =
"<p>this kind of text i'm storing into database</p><pre class="code-
pre">var uri = "my test.asp?name=ståle&car=saab";
var enc = encodeURI(uri);
var dec = decodeURI(enc);
var res = enc + "<br>" + dec;
</pre>"
I replaced above string with as below
htmlCodeToBeStored = htmlCodeToBeStored.replace(/"/g, "\"")
with that simple change i'm able to store my ans into data base.
var searchModel = #Html.Raw(Json.Encode(Model.schoolSearch));
Above code successfully encodes Model.schoolSearch to searchModel.
How can I get reverse?
I have json as a string I need to encode it as Model.schoolSearch
I have tried:
var model = #Html.Raw(Json.Decode(jsonText, Model.schoolSearch));
and
var model = #Html.Raw(Json.Decode<Model.schoolSearch>(jsonText));
But not working.
I want to get compress layer data from tmx file . Who knows libraries for decompress gzip and zlib string in javascript ? I try zlib but it doesn't work for me . Ex , layer data in tmx file is :
<data encoding="base64" compression="zlib">
eJztwTEBAAAAwqD1T20JT6AAAHgaCWAAAQ==
</data>
My javascript code is
var base64Data = "eJztwTEBAAAAwqD1T20JT6AAAHgaCWAAAQ==";
var compressData = atob(base64Data);
var inflate = new Zlib.Inflate(compressData);
var output = inflate.decompress();
It runs with displays message error "unsupported compression method" . But I try decompress with online tool as http://i-tools.org/gzip , it returns correct string.
Pako is a full and modern Zlib port.
Here is a very simple example and you can work from there.
Get pako.js and you can decompress byteArray like so:
<html>
<head>
<title>Gunzipping binary gzipped string</title>
<script type="text/javascript" src="pako.js"></script>
<script type="text/javascript">
// Get datastream as Array, for example:
var charData = [31,139,8,0,0,0,0,0,0,3,5,193,219,13,0,16,16,4,192,86,214,151,102,52,33,110,35,66,108,226,60,218,55,147,164,238,24,173,19,143,241,18,85,27,58,203,57,46,29,25,198,34,163,193,247,106,179,134,15,50,167,173,148,48,0,0,0];
// Turn number array into byte-array
var binData = new Uint8Array(charData);
// Pako magic
var data = pako.inflate(binData);
// Convert gunzipped byteArray back to ascii string:
var strData = String.fromCharCode.apply(null, new Uint16Array(data));
// Output to console
console.log(strData);
</script>
</head>
<body>
Open up the developer console.
</body>
</html>
Running example: http://jsfiddle.net/9yH7M/
Alternatively you can base64 encode the array before you send it over as the Array takes up a lot of overhead when sending as JSON or XML. Decode likewise:
// Get some base64 encoded binary data from the server. Imagine we got this:
var b64Data = 'H4sIAAAAAAAAAwXB2w0AEBAEwFbWl2Y0IW4jQmziPNo3k6TuGK0Tj/ESVRs6yzkuHRnGIqPB92qzhg8yp62UMAAAAA==';
// Decode base64 (convert ascii to binary)
var strData = atob(b64Data);
// Convert binary string to character-number array
var charData = strData.split('').map(function(x){return x.charCodeAt(0);});
// Turn number array into byte-array
var binData = new Uint8Array(charData);
// Pako magic
var data = pako.inflate(binData);
// Convert gunzipped byteArray back to ascii string:
var strData = String.fromCharCode.apply(null, new Uint16Array(data));
// Output to console
console.log(strData);
Running example: http://jsfiddle.net/9yH7M/1/
To go more advanced, here is the pako API documentation.
I can solve my problem by zlib . I fix my code as below
var base64Data = "eJztwTEBAAAAwqD1T20JT6AAAHgaCWAAAQ==";
var compressData = atob(base64Data);
var compressData = compressData.split('').map(function(e) {
return e.charCodeAt(0);
});
var inflate = new Zlib.Inflate(compressData);
var output = inflate.decompress();
For anyone using Ruby on Rails, who wants to send compressed encoded data to the browser, then uncompress it via Javascript on the browser, I've combined both excellent answers above into the following solution. Here's the Rails server code in my application controller which compresses and encodes a string before sending it the browser via a #variable to a .html.erb file:
require 'zlib'
require 'base64'
def compressor (some_string)
Base64.encode64(Zlib::Deflate.deflate(some_string))
end
Here's the Javascript function, which uses pako.min.js:
function uncompress(input_field){
base64data = document.getElementById(input_field).innerText;
compressData = atob(base64data);
compressData = compressData.split('').map(function(e) {
return e.charCodeAt(0);
});
binData = new Uint8Array(compressData);
data = pako.inflate(binData);
return String.fromCharCode.apply(null, new Uint16Array(data));
}
Here's a javascript call to that uncompress function, which wants to unencode and uncompress data stored inside a hidden HTML field:
my_answer = uncompress('my_hidden_field');
Here's the entry in the Rails application.js file to call pako.min.js, which is in the /vendor/assets/javascripts directory:
//= require pako.min
And I got the pako.min.js file from here:
https://github.com/nodeca/pako/tree/master/dist
All works at my end, anyway! :-)
I was sending data from a Python script and trying to decode it in JS. Here's what I had to do:
Python
import base64
import json
import urllib.parse
import zlib
...
data_object = {
'_id': '_id',
...
}
compressed_details = base64.b64encode(zlib.compress(bytes(json.dumps(data_object), 'utf-8'))).decode("ascii")
urlsafe_object = urllib.parse.quote(str(compressed_details))#.replace('%', '\%') # you likely don't need this last part
final_URL = f'https://my.domain.com?data_object={urlsafe_object}'
...
JS
// npm install this
import pako from 'pako';
...
const urlParams = new URLSearchParams(window.location.search);
const data_object = urlParams.get('data_object');
if (data_object) {
const compressedData = Uint8Array.from(window.atob(data_object), (c) => c.charCodeAt(0));
originalObject = JSON.parse(pako.inflate(compressedData, { to: 'string' }));
};
...
I've written a PHP-script that parses a list from remote website and output the result as JSON form my iPhone app which is built on Titanium Mobile.
This is my header: header('content-type:application/json;charset=utf-8');
Also tried with ISO-8859-1 but problem persists.
I print the textResponse in the titanium console and see that the &-characters are represented as &. Same result when I make the same request in my web browser.
I try to replace & with & using replace('&', '&') but it has no effect, & is still &.
var events = JSON.parse(this.responseText);
Titanium.API.info(events);
for (var i = 0; i < events.length; i++) {
var id = events[i].id;
var title = events[i].title;
var amp = title.search('&');
if (amp != -1) {
title.replace('&', '&');
Titanium.API.info(amp);
Titanium.API.info(title);
}
var row = Titanium.UI.createTableViewRow({title: title, id: id, hasChild: true});
rowData[i] = row;
}
title = title.replace('&', '&');
You should post your php script as reference. You may want to make sure you are decoding the URLs prior to printing them to the JSON.
