I want to convert below String to URL
www.mydomain.com/key=अक्षय
I tried let urlToSend = URL(string: "www.mydomain.com/key=अक्षय")!
but it returns nil.
I'm getting that 'अक्षय' keyword from textField, it could be in any local language.
It works fine with English but not working with local language.
I used let url = URL(string: "www.mydomain.com")?.appendingPathComponent("key=अक्षय")
it gives www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
but now I want to www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
to www.mydomain.com/key=अक्षय
When working with URLs as strings, you should encode them to be valid as a URL; One of the most popular examples of encoding the URL is that the " " (space) would be encoded as "%20".
So in your case the encoded value of your url should be:
www.mydomain.com%2Fkey=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
As you noticed the value of the key
is changed
from: "अक्षय"
to:"%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF"
which will let the URL to be valid.
How to:
you could get the above result like this:
let string = "www.mydomain.com/key=अक्षय"
if let encodedString = string.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed), let url = URL(string: encodedString) {
print(url) // www.mydomain.com%2Fkey=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
}
Note that there is optional binding for both the encoded string and the url for the purpose of being safe.
Decoding the URL:
You could also returns to the original unencoded url (decoding it) like this:
let decodedString = "www.mydomain.com%2Fkey=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF"
if let unwrappedDecodedString = decodedString.removingPercentEncoding {
print(unwrappedDecodedString) // www.mydomain.com/key=अक्षय
}
Again, optional binding to be safe.
You need to encode the URL.
let urlString = "www.mydomain.com/key=अक्षय".addingPercentEncoding(withAllowedCharacters: .urlPathAllowed)
let url = URL(string: urlString!)
let decodedUrl = urlString?.removingPercentEncoding
Keep in mind that you shouldn't force unwrap URL's and strings, use if let or guard statements.
Try this thing:
let strURL = "www.mydomain.com/key=अक्षय".addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
let url = URL(string: strURL!)
Or you can use:
let strURL = "www.mydomain.com/key=अक्षय".addingPercentEncoding(withAllowedCharacters: .urlPathAllowed)
let url = URL(string: strURL!)
Instead of dealing with percent encodings explicitly, you can also build the URL piece by piece, using appendingPathComponent
:
let url = URL(string: "www.mydomain.com")?.appendingPathComponent("key=अक्षय")
// www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
Swift3.0
let baseUrl = "www.mydomain.com/key=अक्षय" // base url
let encodedUrl : String! = baseUrl.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) // remove the spaces in the url string
let typeUrl = URL(string: encodedUrl)! // convert the string into url
print(typeUrl) // www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
For Checking purpose
if let unwrappedDecodedString = encodedUrl.removingPercentEncoding {
print(decodedString) // www.mydomain.com/key=अक्षय
