Online URL Encoder

I'm trying to deploy my production ready code to Heroku to test it. Unfortunately, it is not taking JSON data so we converted into x-www-form-urlencoded.

params = urllib.parse.quote_plus(json.dumps({    'grant_type': 'X',    'username': 'Y',    'password': 'Z'}))r = requests.post(URL, data=params)print(params)

It is showing an error in this line as I guess data=params is not in proper format.

Is there any way to POST the urlencoded parameters to an API?

Many languages, such as JavaScript and PHP, have a urlencode() function which one can use to encode the content of a query string parameter.

"example.com?value=" + urlencode("weird string & number: 123")

This ensures that the &, %, spaces, etc. get encoded so your URL remains valid.

I see that golang offers a URL package and it has an Encode() function for query string values. This works great, but in my situation, it would require me to parse the URL and I would prefer to not do that.

My URLs are declared by the client and not changing the order and potential duplicated parameters (which is a legal thing in a URL) could be affected. So I use a Replace() like so:

func tweak(url string) string {  url.Replace("@VALUE@", new_value, -1)  return url}

The @VALUE@ is expected to be used as the value of a query string parameter as in:

example.com?username=@VALUE@

So, what I'd like to do is this:

  url.Replace("@VALUE@", urlencode(new_value), -1)

Is there such a function readily accessible in Golang?

I have an .avi file, which is located in a folder in my server. This folder's name has an accent mark.The thing is, when I put that file within a tag, it shows a txt file (the avi files codification, I asume) which obviously is an error. It just happens in Internet Explorer (version 11 at least) with https protocol.

This doesn't happend with mp4 files, neither with avi files which are located in a "non accented folder", neither with http protocol, neither when I paste the address directly in the browser, neither with Chrome or Firefox.

Examples to illustrate what I'm trying to say:

<a href="https://myserver.com/myAccentédFolder/myVid.avi" target="_blank">ERROR</a><a href="https://myserver.com/myNonAccentedFolder/myVid.avi" target="_blank">OK 1</a><a href="https://myserver.com/myAccentédFolder/myVid.mp4" target="_blank">OK 2</a><a href="http://myserver.com/myAccentédFolder/myVid.avi" target="_blank">OK 3</a>

So I know how to "fix" it… but what if I need all the casuistries?- Work with IE 11- The file to be .avi- The folder to have an accent mark- The address to be within a link- The address to be https protocol

What the %$&$% is going on?

It’s common that I make a request in Ruby that fails because the server doesn’t like the encoding. A common example is having spaces as + when the server only understands %20. Today I bumped into a server that doesn’t like unencoded hyphens (-), requiring %2D instead.

I’ve tried CGI.escape, URI.escape, ERB::Util.url_encode, WEBrick::HTTPUtils.escape, and none encodes hyphens.

In the past I’ve resorted to gsubing the offending characters as needed, but as I find more servers with more idiosyncrasies, I’d prefer a more stable solution.

Is there a standard (i.e. no external dependencies) approach that percent encodes everything that’s possible?

I’m not looking for just hyphen encoding or gsubing everything one at a time.

I am trying to open following URL in WKWebview,

https://chart.googleapis.com/chart?chs=200x200&chld=M|0&cht=qr&chl=otpauth://totp/mynameisanthony@gmail.com?secret=B6S2LGJTQHIDKIMU&issuer=someapp+Auth

        strQRImage =  @"https://chart.googleapis.com/chart?chs=200x200&chld=M|0&cht=qr&chl=otpauth://totp/mynameisanthony@gmail.com?secret=B6S2LGJTQHIDKIMU&issuer=someapp+Auth";        NSURL *url = [NSURL URLWithString:strQRImage];        [webview loadRequest:[NSURLRequest requestWithURL:url]];

when I run this code it gives nil value in url
