Online URL Encoder

I have a url that looks like that

http://example.com/index.php?id=111&title=word1 word2 word3

I need to encode the spaces before requesting the url with curl.

But how to urlencode the right parts of the url.

urlencode and rawurlencode encode the slashes of https the question mark etc.

I have a database 'myc' with documents, as

{  "total_rows": 3,  "offset": 0,  "rows": [{    "id": "lscc\u0000mycc",    "key": "lscc\u0000mycc",    "value": {      "rev": "1-35f379c3ea35ef0077b595923bf36151"    }  }, {    "id": "mycc\u0000a",    "key": "mycc\u0000a",    "value": {      "rev": "2-f3049e0b19f6969f01671889c8b1456f"    }  }, {    "id": "statedb_savepoint",    "key": "statedb_savepoint",    "value": {      "rev": "3-62ba0d88e905ef321c85c542bec7bd15"    }  }]}

I need to get the value stored in the keys/id like lscc\u0000mycc or mycc\u0000a.

When the keys are URL safe, we can just call http://localhost:5984/myc/statedb_savepoint. How do I access the same using GET request?

When I run, for example,

var uts46 = require('punycode');uts46.encode("💩⚽️🍊")

the output is:

xn--y8hw789ec0vgbfb

However, when I type the very same string of emojis ("💩⚽️🍊") into the address bar in Chrome, it resolves to

xn--y8h2559nb4a

Punycoder.com resolves to the second string as well.

Does anyone know why this could be, and how to alter punycode.js to produce the Chrome string?

I have the following code:

String a1 = "gùt";String a2 = "gùt";

When I do

URLEncoder.encode(a1, "UTF-8")URLEncoder.encode(a2, "UTF-8")

I am receiving different results. How is this possible?I was counting on the fact that I am receiving the same result. Is there a way I can use the encoder and get the same result for the same string value?

I'm looking for a (fast) standard implementation for base64url according to RFC4648 in C#.

I found HttpServerUtility.UrlTokenEncode but it looks like this doesn't follow RFC4648 (UrlTokenEncode adds a number at the end which indicates the number of = signs that were removed; see here and here).

Example:

base64 encoding:

Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes("AA")); //returns "QUE="

base64url encoding:

HttpServerUtility.UrlTokenEncode(System.Text.Encoding.ASCII.GetBytes("AA")); //returns "QUE1" but I would expect "QUE"
